An 8-digit permanent numerical designation for all gaging stations has been adopted on a nationwide basis; stations are numbered and listed in downstream order. In the downstream direction along the main stem, all stations on a tributary entering between two main-stem stations are listed between these two stations. A similar order is followed in listing stations by first rank, second rank, and other ranks of&nbsp;tributaries. The rank of any tributary, with respect to the stream to which it is an immediate tributary, is indicated by an indention in the table. Each indention represents one rank. This downstream order and system of indention shows which gaging stations are on tributaries between any two stations on a main stem and the rank of the tributary on which each gaging station is situated.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr01103","usgsCitation":"2001, Index of stations— Surface-water

The data are in support of the project \"Prediction of Trace Element Removal from Coal\" --a Cooperative Research and Development Agreement (CRADA) with CQ Inc. The purpose of this CRADA is to apply modes of occurrence information to coal cleaning procedures. Techniques used in this study include sequential selective leaching procedures, scanning electron microscopy, X-ray diffraction analysis, and electron microprobe analysis. Selective leaching results indicate that greater than 40 percent of the elements Co, U, Be, Ca, Fe, Mn, Ba, Zn, Cd, Pb are associated with HCIsoluble carbonates, iron oxides, or monosulfides, greater than 40 percent of the Al, Cr and Mo are associated with HF-soluble silicates, greater than 40 percent of the Ni, Cu, As and Sb are associated with acid-insoluble phases and/or organic matter, and greater than 50 percent of the Hg is associated with HMDs-soluble pyrite. Thirty percent of the Th was leached by HCI and 30 percent of this element was leached by HF. Scanning electron microscopy indicates that quartz, kaolinite, illite and iron oxide, possibly hematite, are the major minerals present. X-ray diffraction analysis confirmed that quartz, kaolinite and hematite are present, but did not determine illite, indicating that illite in these coals is of low abundance or is poorly crystalline. Electron microprobe data indicate that concentrations of the chalcophile elements As, Se, Cu, Ni, Zn, and Cd in most pyrite grains are at or below the detection limit of about 100-200 ppm in both the as-mined coal and its corresponding simulated cleaned coal product. The results of this project should aid in the development of models for predicting the response of potentially toxic trace elements in commercial coal cleaning procedures.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr00323","usgsCitation":"Palmer, C., Mroczkowski, S.J., Kolker, A., Finkelman, R., and Bullock, J.H., 2001, Chemical analysis and modes of occurrence of selected trace elements in a Powder River basin coal and its corresponding simulated cleaned coal: U.S. Geological Survey Open-File Report 2000-323, 53 p. , https://doi.org/10.3133/ofr00323.","productDescription":"53 p.

In particular,\r\nloss of those coral species that\r\nare the building blocks of solid reef\r\nframework has significant negative\r\nimplications for economic vitality of\r\nthe region. What are the reasons for\r\nthis decline? Is it due to natural\r\nchange, or are human activities (recreational\r\ndiving, ship groundings,\r\nfarmland runoff, nutrient influx,\r\nair-borne contaminants, groundwater\r\npollutants) a contributing factor\r\nand if so, to what extent? At risk\r\nof loss are biologic resources of the\r\nreefs, including habitats for endangered\r\nspecies in shoreline mangroves,\r\nproductive marine and wetland\r\nnurseries, and economic fisheries.\r\nA healthy reef ecosystem builds\r\na protective offshore barrier to catastrophic\r\nwave action and storm\r\nsurges generated by tropical storms\r\nand hurricanes. In turn, a healthy\r\nreef protects the homes, marinas,\r\nand infrastructure on the Florida\r\nKeys that have been designed to\r\ncapture a lucrative tourism industry.\r\nA healthy reef ecosystem also protects\r\ninland agricultural and livestock\r\nareas of South Florida whose\r\nproduce and meat feed much of the\r\nUnited States and other parts of the\r\nworld.\r\nIn cooperation with the National\r\nOceanic and Atmospheric Administration's\r\n(NOAA) National Marine\r\nSanctuary Program, the U.S. Geological\r\nSurvey (USGS) continues longterm\r\ninvestigations of factors that may\r\naffect Florida's reefs. One of the first\r\nsteps in distinguishing between natural\r\nchange and the effects of human\r\nactivities, however, is to determine\r\nhow coral reefs have responded to\r\npast environmental change, before the\r\nadvent of man. By so doing, accurate\r\nscientific information becomes available\r\nfor Marine Sanctuary management\r\nto understand natural change and\r\nthus to assess and regulate potential\r\nhuman impact better. The USGS studies\r\ndescribed here evaluate the distribution\r\n(location) and historic vitality\r\n(thickness) of Holocene reefs in South\r\nFlorida, relative to type of underlying\r\nbedrock morphology, and their varied\r\nnatural response to rising sea level.\r\nThese studies also assess movement\r\nand accumulation of sands, relative\r\nto direction of prevailing energy, and\r\norigin of the component sand grains.\r\nGeophysical data collected with highresolution\r\nsound-wave instruments\r\nthat provide pictures of the sediment\r\nand bedrock are used to interpret\r\nsediment thickness. Reef thickness is\r\ndetermined by collecting limestone\r\nrock cores by drilling. Drill cores\r\nthrough reefs are used to identify the\r\ncoral species that built them and to\r\ndetermine how reefs reacted to rising\r\nsea level. These data are supplemented\r\nby using isotope-dating techniques to\r\nderive the carbon-14 (C14) age of the\r\ncorals and mangrove peat in the cores.\r\nMangrove peat forms in very shallow\r\nwater and at the shoreline but is found\r\ntoday buried beneath offshore reefs.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey,","doi":"10.3133/ofr00164","issn":"0094-9140","usgsCitation":"Lidz, B.H., 2001, Environmental quality and preservation; reefs, corals, and carbonate sands; guides to reef-ecosystem health and environment: U.S. Geological Survey Open-File Report 2000-164, 3 sheets (2 folded) (6 p., [1] leaf of plates) :ill.

The geologic framework of the Roseburg area was established by the pioneering work of Diller (1898), Wells and Peck, (1961) and Ewart Baldwin (1974) and his students (see figure 3 in pamphlet, also shown on map sheet). Baldwin and his students focussed on the history of the Eocene Tyee basin, where the sediments lap across the tectonic boundary with the Mesozoic terranes and record the accretion of the Coast Range basement to the continent. Others have examined the sedimentary fill of the Tyee basin in detail, recognizing the deep marine turbidite facies of the Tyee Formation (Snavely and others, 1964) and proposing several models for the Eocene evolution of the forearc basin (Heller and Ryberg, 1983; Chan and Dott, 1983; Heller and Dickinson, 1985; Molenaar, 1985; see Ryu and others, 1992 for a comprehensive summary). Along the eastern margin of the quadrangle, both the Tyee basin and the Klamath terranes are overlain by Eocene volcanic rocks of the Western Cascade arc (Walker and MacLeod, 1991).\n\nThe thick Eocene sedimentary sequence of the Tyee basin has significant oil and gas potential (Armentrout and Suek, 1985; Gautier and others, 1993; Ryu and others, 1996). Although 13 deep test wells have been drilled in the Roseburg quadrangle (see figure 2 and table 1 in pamphlet, also shown on map sheet), exploration to date has been hampered by an incomplete understanding of the basin�s tectonic setting and evolution. In response, the Oregon Department of Geology and Mineral Industries (DOGAMI) initiated a five year assessment of the oil and gas potential of the Tyee basin.\n\nThis map is a product of a cooperative effort by the U. S. Geological Survey, Oregon State University, and DOGAMI to systematically map the sedimentary facies and structure of the Tyee basin. New geologic mapping of twenty-eight 7.5' quadrangles is summarized on the map (see figure 3, also shown on map sheet), and the digital database contains geologic information suitable for both 1:100K and 1:24K scale analysis. DOGAMI has published a compilation and synthesis of previous mapping (Niem and Niem, 1990), a basin-wide sequence stratigraphic model and correlations (Ryu and others, 1992), and a report on the oil and gas potential (Ryu and others, 1996). Readers interested in the oil and gas potential of the Roseburg quadrangle should use the map in combination with Ryu and others (1996) to address specific stratigraphic units and structural plays.\n\nStratigraphic terminology for the Tyee basin adopts the type sections, formation names, and framework of Ryu and others (1992, 1996), which were developed concurrently with the mapping and are recognized throughout the basin. For detailed discussion of nomenclature, type sections, lithology, thickness and distribution, age, contact relationships, and depositional environment of stratigraphic units, the reader is referred to Ryu and others (1992). In this report we focus on the spatial, temporal, and structural relationships between units revealed by geologic mapping. Map unit ages (see figure 4 in pamphlet, also shown on map sheeet) are adjusted slightly from Ryu and others (1992, 1996) to fit new coccolith age determinations (D. Bukry, cited in pamphlet), paleomagnetic polarity data (Simpson, 1977 and new data cited in pamphlet), and the time scale of Berggren and others (1995).","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr00376","usgsCitation":"Wells, R., Jayko, A.S., Niem, A.R., Black, G., Wiley, T., Baldwin, E., Molenaar, K.M., Wheeler, K., DuRoss, C., and Givler, R., 2001, Geologic map and database of the Roseburg 30' x 60' quadrangle, Douglas and Coos Counties, Oregon: U.S. Geological Survey Open-File Report 2000-376, Report: 55 p., 3 ReadMe files, 2 Plates: 49.09 x 31.30 inches and 43.89 33.06 inches, https://doi.org/10.3133/ofr00376.","productDescription":"Report: 55 p., 3 ReadMe files, 2 Plates: 49.09 x 31.30 inches and 43.89 33.06 inches","numberOfPages":"55","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":161054,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr00376.png"},{"id":397740,"rank":10,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_34069.htm","linkFileType":{"id":5,"text":"html"}},{"id":281852,"rank":3,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2000/0376/rbofrps.tar.gz","linkFileType":{"id":6,"text":"zip"}},{"id":281851,"rank":2,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2000/0376/rbofr.tar.gz","linkFileType":{"id":6,"text":"zip"}},{"id":281845,"rank":4,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0376/pdf/rb_geol.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":281846,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2000/0376/pdf/rb_sh2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":281847,"rank":6,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2000/0376/pdf/rb_sh1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":281848,"rank":7,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/2000/0376/rb_readme.txt","linkFileType":{"id":2,"text":"txt"}},{"id":281849,"rank":8,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/2000/0376/pdf/rb_readme.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":281850,"rank":9,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/2000/0376/rb_readme.doc"},{"id":2679,"rank":11,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/0376/","linkFileType":{"id":5,"text":"html"}}],"scale":"100000","datum":"National Geodetic Datum of 1929","country":"United States","state":"Oregon","county":"Coos County, Douglas County","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.0,43.0 ], [ -124.0,43.5 ], [ -123.0,43.5 ], [ -123.0,43.0 ], [ -124.0,43.0 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b15e4b07f02db6a49cc","contributors":{"authors":[{"text":"Wells, Ray E. 0000-0002-7796-0160 rwells@usgs.gov","orcid":"https://orcid.org/0000-0002-7796-0160","contributorId":2692,"corporation":false,"usgs":true,"family":"Wells","given":"Ray E.","email":"rwells@usgs.gov","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":false,"id":205216,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jayko, A.

Additional channel modification activities are likely on the Yellowstone, and there is concern over the short- and long-term cumulative effects of channel modification activities on physical processes and dynamics of the river, associated riparian vegetation, and fish and wildlife resources that depend on the river.</p>\n<p>This document represents a first step toward conservation of the riparian vertebrate community on the upper Yellowstone River, with expected changes due to bank stabilization activities. Conservation strategies should be based on the life histocy attributes of the species of interest and the expected landscape changes for a specific geographic region. In this document, species accounts summarize the distribution, abundance, life histories, and habitat associations of 69 bird species, 4 amphibian species, 5 reptile species, and 9 species of mammals known or assumed to occur in the study area, including 38 species designated as species of interest. A matrix is presented to assist managers in evaluating the degree to which a species may be negatively affected by riverbank stabilization activities.</p>\n<p>The degree of vulnerability of birds to bank stabilization activities and changes in stream flow is strongly related to the degree to which the species is tied to riparian habitats. Of birds, the 13 species that are riparian obligates are the most vulnerable to bank stabilization activities. Belted Kingfishers would suffer if fish populations decline. Harlequin Ducks, Spotted Sandpipers, and American Dippers would be negatively influenced by changes in stream and bank morphology, especially the loss of shallow water and braided channels.

Four sites within the study area were continuously monitored using multiparameter recorders. Water quality sampling was also performed at these four locations in 1996 and 1997. Additional water quality sampling sites were added in 1998 for a total of 8 locations between Keno and Seiad.</p>\n<p>Temperature ranged from near zero &deg;C to &gt;25 &deg;C with cooler temperatures in early spring and fall, and maximum temperatures occurring in july and August of each year. Dissolved oxygen concentration ranged from near zero mg/L to &gt;13 mg/L with highest DO occurring in early spring and fall and lowest DO occurring in mid-summer. Air temperature was generally highly correlated with water temperature with r values ranging from 0.8 to 0.9 during the study period from 1996-1998. Water temperature in the study area exceeded chronic (&gt;16&deg;C) and acute (&gt;22&deg;C) criteria for salmonids during the summer months. Although chronic DO &laquo;7 mg/L) criteria were exceeded throughout most of the study area during the summer, in the free-flowing river below Iron Gate Dam the acute DO &laquo;5.5 mg/L) criteria were not exceeded.</p>\n<p>Nonpoint source pollution in the form of agricultural return flows, industrial, or sewage effluent entering the stream may have resulted in higher ammonia and total organic nitrogen concentrations at the upstream locations in the Klamath River study area (Keno and J.C. Boyle Powerplant). Nitrification of ammonia and organic nitrogen seemed to result in higher concentrations of nitrate in the downstream Klamath River (Iron Gate Dam). Total phosphorus concentration stayed relatively stable through the reservoirs in the study area, but decreased in the downstream direction between Iron Gate Dam and Seiad. Ortho-phosphorus concentrations increased longitudinally through the reservoirs, then decreased in the downstream direction between Iron Gate Dam and Seiad. An increase in ortho-phosphorus concentration can indicate internal cycling occurring in the reservoirs as well as photosynthesis.</p>\n<p>On an annual basis total phosphorus loading increased longitudinally from up- to downstream between Keno and Seiad. The increase was statistically significant (p =.03) indicating that the reservoirs in series in the Klamath River study area do not function as a nutrient sink. However, during the summer there was no statistically significant difference in total P loading when Keno, Iron Gate and Seia~ locations were compared, therefore, the reservoirs may act as a nutrient sink seasonally.</p>\n<p>The Klamath River study locations were generally nitrogen limited, although at Keno, a regUlar change from N limitation to P limitation occurred during the fall of all three years of the study. When the Klamath River annual nutrient loading values are compared to other rivers in the vicinity, the Carson, Truckee, and Long Tom Rivers also appear to be nutrient enriched. The Carson and South Yamhill Rivers seem to be N limited systems and the Wood, Long Tom, Snake and Truckee Rivers seem to be P limited systems.</p>\n<p>Implementing management strategies for reservoir operations to improve water quality and reduce nutrient concentration or loading in the Klamath River study area to benefit anadromous fisheries may be difficult and expensive. However, improving the thermal regime in spring to benefit YOY salmonids may be possible as is short-term relief in late summer for oversummering species. Decreases in nutrient concentration or loading accomplished through best management practices in the water shed may allow general protection of water resources in the Klamath Basin for future needs.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr2001301","usgsCitation":"Campbell, S.G., 2001, Water quality and nutrient loading in the Klamath River between Keno, Oregon and Seiad Valley, CA from 1996-1998: U.S. Geological Survey Open-File Report 2001-301, Report: vii, 55 p.; Data, https://doi.org/10.3133/ofr2001301.","productDescription":"Report: vii, 55 p.; Data","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":179581,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr2001301.PNG"},{"id":321213,"rank":3,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2001/0301/data.zip","text":"Data","linkFileType":{"id":6,"text":"zip"}},{"id":321212,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0301/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"California, Oregon","otherGeospatial":"Klamath River Watershed","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.1949462890625,\n              40.451127265872316\n            ],\n            [\n              -124.1949462890625,\n              42.98857645832184\n            ],\n            [\n              -121.058349609375,\n              42.98857645832184\n            ],\n            [\n              -121.058349609375,\n              40.451127265872316\n            ],\n            [\n              -124.1949462890625,\n              40.451127265872316\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0de4b07f02db5fd3c2","contributors":{"authors":[{"text":"Campbell, Sharon G.","contributorId":23173,"corporation":false,"usgs":true,"family":"Campbell","given":"Sharon","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":241439,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

ARC/INFO (Environmental Systems Research Institute) version 7.2.1 double-precision coverages of the various elements of the geologic map\n2. A PostScript (.ps) file to plot the geologic map on a topographic base, containing a Correlation of Map Units diagram and a Description of Map Units\n3. Portable Document Format (.pdf) files of:\na. This Readme; includes in Appendix I, data contained in fskn_met.txt\n\nb. The same graphic as plotted in 2 above. (Test plots from this .pdf do not produce 1:24,000-scale maps. Adobe Acrobat page-size settings control map scale.)\n\nThis release includes features not found in most other digital geologic maps, in that all polygons, lines, and points in the coverage are encoded with detailed, comprehensive geologic data contained in six INFO data tables (.rel). (See Matti and others, 1998a, 1998b, and 1998c, for information on how the encoding may be accessed and utilized.) No paper map is included in the Open-File Report, but a PostScript plot file containing an image of the geologic map sheet, topographic base, Correlation of Map Units (CMU), and detailed Description of Map Units (DMU) is. The Correlation of Map Units and Description of Map Units are in the editorial format of USGS Miscellaneous Investigations Series maps (I-maps) but have not been edited to comply with I-map standards. Within the geologic map data package, map units are identified by such standard geologic-map criteria as formation name, age, and lithology. Even though this is an author-prepared report, every attempt has been made to closely adhere to the stratigraphic nomenclature of the U.S. Geological Survey. Descriptions of units can be obtained by viewing or plotting the .pdf file (3b above) or plotting the PostScript file (2 above).

This document provides a brief introduction into how to run and use the programs ph2dt and hypoDD to compute double-difference (DD) hypocenter locations. It gives a short overview of the DD technique, discusses the data preprocessing using ph2dt, and leads through the earthquake relocation process using hypoDD. The appendices include the reference manuals for the two programs and a short description of auxiliary programs and example data. Some minor subroutines are presently in the c language, and future releases will be in c.</p>\n<br/>\n<p>Earthquake location algorithms are usually based on some form of Geiger’s method, the linearization of the travel time equation in a first order Taylor series that relates the difference between the observed and predicted travel time to unknown adjustments in the hypocentral coordinates through the partial derivatives of travel time with respect to the unknowns. Earthquakes can be located individually with this algorithm, or jointly when other unknowns link together the solutions to indivdual earthquakes, such as station corrections in the joint hypocenter determination (JHD) method, or the earth model in seismic tomography.</p>\n<br/>\n<p>The DD technique (described in detail in Waldhauser and Ellsworth, 2000) takes advantage of the fact that if the hypocentral separation between two earthquakes is small compared to the event-station distance and the scale length of velocity heterogeneity, then the ray paths between the source region and a common station are similar along almost the entire ray path (Fréchet, 1985; Got et al., 1994). In this case, the difference in travel times for two events observed at one station can be attributed to the spatial offset between the events with high accuracy.</p>\n<br/>\n<p>DD equations are built by differencing Geiger’s equation for earthquake location. In this way, the residual between observed and calculated travel-time difference (or double-difference) between two events at a common station are a related to adjustments in the relative position of the hypocenters and origin times through the partial derivatives of the travel times for each event with respect to the unknown. HypoDD calculates travel times in a layered velocity model (where velocity depends only on depth) for the current hypocenters at the station where the phase was recorded. The double-difference residuals for pairs of earthquakes at each station are minimized by weighted least squares using the method of singular value decomposition (SVD) or the conjugate gradients method (LSQR, Paige and Saunders, 1982). Solutions are found by iteratively adjusting the vector difference between nearby hypocentral pairs, with the locations and partial derivatives being updated after each iteration. Details about the algorithm can be found in Waldhauser and Ellsworth (2000).</p>\n<br/>\n<p>When the earthquake location problem is linearized using the double-difference equations, the common mode errors cancel, principally those related to the receiver-side structure. Thus we avoid the need for station corrections or high-accuracy of predicted travel times for the portion of the raypath that lies outside the focal volume. This approach is especially useful in regions with a dense distribution of seismicity, i.e. where distances between neighboring events are only a few hundred meters. The improvement of double-difference locations over ordinary JHD locations is shown in Figure 1 for about 10,000 earthquakes that occurred during the 1997 seismic crisis in the Long Valley caldera, California. While the JHD locations (left panel) show a diffuse picture of the seismicity, double-difference locations (right panel) bring structural details such as the location of active fault planes into sharp focus.</p>","language":"English","doi":"10.3133/ofr01113","usgsCitation":"Waldhauser, F., 2001, hypoDD-A Program to Compute Double-Difference Hypocenter Locations (Version 1.0): U.S. Geological Survey Open-File Report 2001-113, 25 p., https://doi.org/10.3133/ofr01113.","productDescription":"25 p.","onlineOnly":"Y","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":175481,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":4190,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0113/","linkFileType":{"id":5,"text":"html"}},{"id":282065,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0113/pdf/hypoDD.pdf"},{"id":282066,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2001/0113/HYPODD_1.0.tar.gz"}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ce4b07f02db5fc319","contributors":{"authors":[{"text":"Waldhauser, Felix","contributorId":59106,"corporation":false,"usgs":true,"family":"Waldhauser","given":"Felix","email":"","affiliations":[],"preferred":false,"id":241347,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
