The investigation was designed to determine if metals and organic compounds historically used in industrial operations at the site resulted in a threat to the water resources in the area. The hydraulic units of concern in the study area are the upper semiconfining unit, the sand aquifer, and the lower semiconfining unit. The upper semiconfining unit ranges from about 1 to 19 feet in thickness and is composed of silt-and clay deposits with a geometric mean vertical hydraulic conductivity of 7.1 ? 10-3 feet per day. The sand aquifer is composed of a 1 to 5.5 foot thick sand deposit and is considered the primary pathway for ground-water flow and contaminant migration from beneath the study area. The geometric mean of the horizontal hydraulic conductivity of the sand aquifer was calculated to be 1.8 feet per day. The direction of flow in the sand aquifer is to the east, south, and west, away from a ground-water ridge that underlies the center of the site. Ground-water velocity through the sand aquifer ranges from 7.3 ? 10-2 to 2.7 ? 10-1 feet per day. The lower semiconfining unit is composed of sandy silt-and-clay deposits with a geometric mean vertical hydraulic conductivity of 1.1 ? 10-3 feet per day.\r\nVolatile organic compounds were detected in ground water beneath the study area. Pesticide compounds were detected in ground water in the western part of the study area. Partial or complete degradation of some of the volatile organic and pesticide compounds is occurring in the soils and ground water beneath the study area. Concentrations of most of the metals and major cations in the ground water show some variation within the study area and may be affected by the presence of a source area, pH, oxidation-reduction potential, precipitation-dissolution reactions, and ion exchange reactions. Antimony, thallium, and 1,1-dichloroethane were detected in water samples from one well each at concentrations above their respective U.S. Environmental Protection Agency maximum contaminant levels.","language":"ENGLISH","doi":"10.3133/ofr01307","usgsCitation":"Kay, R.T., Cornue, D.B., and Ursic, J.R., 2001, Geology, hydrology, and water quality in the vicinity of a brownfield redevelopment site in Canton, Illinois: U.S. Geological Survey Open-File Report 2001-307, 32 p. , https://doi.org/10.3133/ofr01307.","productDescription":"32 p.

San Salvador volcano is one of many volcanoes along the volcanic arc in El Salvador \n(figure 1). This volcano, having a volume of about \n110 cubic kilometers, towers above San Salvador, \nthe country’s capital and largest city. The city has a \npopulation of approximately 2 million, and a \npopulation density of about 2100 people per square \nkilometer. The city of San Salvador and other \ncommunities have gradually encroached onto the \nlower flanks of the volcano, increasing the risk that \neven small events may have serious societal \nconsequences. San Salvador volcano has not \nerupted for more than 80 years, but it has a long \nhistory of repeated, and sometimes violent, eruptions. The volcano is composed of remnants of \nmultiple eruptive centers, and these remnants are \ncommonly referred to by several names. The \ncentral part of the volcano, which contains a large \ncircular crater, is known as El Boquerón, and it \nrises to an altitude of about 1890 meters. El \nPicacho, the prominent peak of highest elevation \n(1960 meters altitude) to the northeast of the crater, \nand El Jabali, the peak to the northwest of the \ncrater, represent remnants of an older, larger \nedifice. The volcano has erupted several times \nduring the past 70,000 years from vents central to \nthe volcano as well as from smaller vents and \nfissures on its flanks [1] (numerals in brackets refer \nto end notes in the report). In addition, several \nsmall cinder cones and explosion craters are \nlocated within 10 kilometers of the volcano. Since \nabout 1200 A.D., eruptions have occurred almost \nexclusively along, or a few kilometers beyond, the \nnorthwest flank of the volcano, and have consisted \nprimarily of small explosions and emplacement of \nlava flows. However, San Salvador volcano has \nerupted violently and explosively in the past, even \nas recently as 800 years ago. When such eruptions \noccur again, substantial population and infrastructure will be at risk.

\n

Volcanic eruptions are not the only events that \npresent a risk to local communities. Another \nconcern is a landslide and an associated debris flow \n(a watery flow of mud, rock, and debris--also \nknown as a lahar) that could occur during periods \nof no volcanic activity. An event of this type \noccurred in 1998 at Casita volcano in Nicaragua \nwhen extremely heavy rainfall from Hurricane \nMitch triggered a landslide that moved down slope \nand transformed into a rapidly moving debris flow \nthat destroyed two villages and killed more than \n2000 people. Historical landslides up to a few \nhundred thousand cubic meters in volume have \nbeen triggered on San Salvador volcano by torrential rainstorms and earthquakes, and some have \ntransformed into debris flows that have inundated \npopulated areas down stream. Destructive rainfall- and earthquake-triggered landslides and debris \nflows on or near San Salvador volcano in September 1982 and January 2001 demonstrate that such \nmass movements in El Salvador have also been \nlethal.

This report describes the kinds of hazardous \nevents that occur at volcanoes in general and the \nkinds of hazardous geologic events that have \noccurred at San Salvador volcano in the past. The \naccompanying volcano-hazards-zonation maps \nshow areas that are likely to be at risk when \nhazardous events occur again.

This map was prepared as a collaborative effort with the Missouri Division of Geology and Land Survey, the Kansas Geological Survey, and the Nebraska Conservation and Survey Division. 

Map units and preliminary contacts between units were identified using stereoscopic pairs of high altitude, false color infrared, aerial photographs. Contacts were drawn on twelve USGS 7.5-minute topographic maps, and were checked in the field. U.S. Department of Agriculture Soil Survey maps at a scale of 1:62,500 for Buchanan County, Andrew County, Platte County, and Doniphan County were used to provide a general overview of the soils of the area. A U.S. Geological Survey map at a scale of 1:24,000 showing the geohydrology of Doniphan County, Kansas; soil surveys at a scale of 1:24,000 for Buchanan County, Andrew County, and Platte County; and soil survey at a scale of 1:20,000 for Doniphan were used to corroborate map contacts and field observations.

Dikes and irregular intrusive bodies of distinctive Oligocene biotite dacite and serially related hornblende latite and felsite occur widely in the central and eastern San Gabriel Mountains, southern California, and are related to the Telegraph Peak granodiorite pluton. Identical dacite is locally present beneath Middle Miocene Topanga Group Glendora Volcanics at the northeastern edge of the Los Angeles Basin, where it is termed Mountain Meadows Dacite. This study mapped the western and southwestern limits of the dacite distribution to understand the provenance of derived redeposited clasts, to perceive Neogene offsets on several large strike-slip faults, to test published palinspastic reconstructions, and to better understand the tectonic boundaries that separate contrasting pre-Tertiary rock terranes where the Peninsular Ranges meet the central and western Transverse Ranges and the Los Angeles Basin.

\n
\n

Transported and redeposited clasts of dacite-latite occur in deformed lower Miocene and lower middle Miocene sandy conglomerates (nonmarine, nearshore, and infrequent upper bathyal) close to the northern and northeastern margins of the Los Angeles Basin for a distance of nearly 60 km. Tie-lines between distinctive source suites and clast occurrences indicate that large tracts of the ancestral San Gabriel Mountains were elevated along range-bounding faults as early as 16–15 Ma. The tie-lines prohibit very large strike-slip offsets on those faults. Transport of eroded dacite began south of the range as early as 18 Ma.

\n
\n

Published and unpublished data about rocks adjacent to the active Santa Monica-Hollywood-Raymond oblique reverse left-lateral fault indicate that cumulative left slip totals 13–14 km and total offset postdates 7 Ma. This cumulative slip, with assembly of stratigraphic and paleogeographic data, invalidates prior estimates of 60 to 90 km of left slip on these faults beginning about 17–16 Ma.

\n
\n

A new and different palinspastic reconstruction of a region southwest of the San Andreas Fault Zone is proposed. Our reconstruction incorporates 20° of clockwise rotation of tracts north of the Raymond Fault from the easternmost Santa Monica Mountains to the Vasquez Creek Fault (San Gabriel south branch). We interpret the Vasquez Creek Fault as a reverse and right-lateral tear fault. Right slip on the tear becomes reverse dip slip on the northeast-striking Clamshell-Sawpit fault complex, interpreted as an offset part of the Mount Lukens Fault. This explains the absence of evidence for lateral offset of the Glendora Volcanics and associated younger marine strata where those are broken farther east by the eastern Sierra Madre reverse fault system. About 34 km of right slip is suggested for all breaks of the San Gabriel fault system.

\n

New paleogeographic maps of the Paleogene basin margin and of a Middle Miocene marine embayment and strandline derive in part from our palinspastic reconstruction. These appealingly simple maps fit well with data from the central Los Angeles Basin to the south and southwest.

San Miguel volcano, also known as Chaparrastique, is one of many volcanoes along the volcanic arc in El Salvador. The volcano, located in the eastern part of the country, rises to an altitude of about 2130 meters and towers above the communities of San Miguel, El Transito, San Rafael Oriente, and San Jorge. In addition to the larger communities that surround the volcano, several smaller communities and coffee plantations are located on or around the flanks of the volcano, and the PanAmerican and coastal highways cross the lowermost northern and southern flanks of the volcano. The population density around San Miguel volcano coupled with the proximity of major transportation routes increases the risk that even small volcano-related events, like landslides or eruptions, may have significant impact on people and infrastructure.

San Miguel volcano is one of the most active volcanoes in El Salvador; it has erupted at least 29 times since 1699. Historical eruptions of the volcano consisted mainly of relatively quiescent emplacement of lava flows or minor explosions that generated modest tephra falls (erupted fragments of microscopic ash to meter sized blocks that are dispersed into the atmosphere and fall to the ground). Little is known, however, about prehistoric eruptions of the volcano. Chemical analyses of prehistoric lava flows and thin tephra falls from San Miguel volcano indicate that the volcano is composed dominantly of basalt (rock having silica content <53%), similar to the lava erupted by Hawaiian volcanoes. The chemical composition of eruptive products and the lack of evidence of large cataclysmic eruptions suggests that prehistoric eruptions probably were similar in nature to the historical eruptions. Unlike San Salvador and San Vicente volcanoes, San Miguel volcano does not appear to have had a history of violent explosive eruptions.

San Vicente volcano, also known as Chichontepec, is one of many volcanoes along the volcanic arc in El Salvador. This composite volcano, located about 50 kilometers east of the capital city San Salvador, has a volume of about 130 cubic kilometers, rises to an altitude of about 2180 meters, and towers above major communities such as San Vicente, Tepetitan, Guadalupe, Zacatecoluca, and Tecoluca. In addition to the larger communities that surround the volcano, several smaller communities and coffee plantations are located on or around the flanks of the volcano, and major transportation routes are located near the lowermost southern and eastern flanks of the volcano. The population density and proximity around San Vicente volcano, as well as the proximity of major transportation routes, increase the risk that even small landslides or eruptions, likely to occur again, can have serious societal consequences.

\n
\n

The eruptive history of San Vicente volcano is not well known, and there is no definitive record of historical eruptive activity. The last significant eruption occurred more than 1700 years ago, and perhaps long before permanent human habitation of the area. Nevertheless, this volcano has a very long history of repeated, and sometimes violent, eruptions, and at least once a large section of the volcano collapsed in a massive landslide. The oldest rocks associated with a volcanic center at San Vicente are more than 2 million years old. The volcano is composed of remnants of multiple eruptive centers that have migrated roughly eastward with time. Future eruptions of this volcano will pose substantial risk to surrounding communities.

It is reproduced here in digital format to make widely available some unique images of mudstones. The images include description, interpretation, and Rock-Eval data that resulted from a high-resolution study of petroleum source rock variation of the Lower Cretaceous succession of the Mobil-Phillips Mikkelsen Bay State #1 well on the North Slope of Alaska. Our mudstone samples with Rock-Eval data plus color images are significant because they come from one of the few continuously cored and complete intervals of the Lower Cretaceous succession on the North Slope. This succession, which is rarely preserved in outcrop and very rarely cored in the subsurface, is considered to include important petroleum source rocks that have not previously been described nor explained \r\n\r\nAnother reason these images are unique is that the lithofacies variability within mudstone dominated successions is relatively poorly known in comparison with that observed in coarser clastic and carbonate successions. They are also among the first published scans of thin sections of mudstone, and are of excellent quality because the sections are well made, cut perpendicular to bedding, and unusually thin, 20 microns. For each of 15 samples, we show a thin section scan (cm scale) and an optical photomicrograph (mm scale) that illustrates the variability present. Several backscattered SEM images are also shown. Rock-Eval data for the samples can be compared with the textures and mineralogy present by correlating sample numbers and core depth. \r\n","language":"ENGLISH","doi":"10.3133/ofr2001480","usgsCitation":"Keller, M.A., Macquaker, J., and Lillis, P.G., 2001, High resolution study of petroleum source rock variation, Lower Cretaceous (Hauterivian and Barremian) of Mikkelsen Bay, North Slope, Alaska: U.S. Geological Survey Open-File Report 2001-480, 3 over-size sheets, 48 x 24 inches, https://doi.org/10.3133/ofr2001480.","productDescription":"3 over-size sheets, 48 x 24 inches","costCenters":[{"id":647,"text":"Western Earth Surface Processes","active":false,"usgs":true}],"links":[{"id":161108,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":8868,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/of01-480/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae1e4b07f02db68898e","contributors":{"authors":[{"text":"Keller, Margaret A. mkeller@usgs.gov","contributorId":1017,"corporation":false,"usgs":true,"family":"Keller","given":"Margaret","email":"mkeller@usgs.gov","middleInitial":"A.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":206416,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Macquaker, Joe H.S.","contributorId":21596,"corporation":false,"usgs":true,"family":"Macquaker","given":"Joe H.S.","affiliations":[],"preferred":false,"id":206418,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lillis, Paul G. 0000-0002-7508-1699 plillis@usgs.gov","orcid":"https://orcid.org/0000-0002-7508-1699","contributorId":1817,"corporation":false,"usgs":true,"family":"Lillis","given":"Paul","email":"plillis@usgs.gov","middleInitial":"G.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":206417,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":31552,"text":"ofr01223 - 2001 - Digital mapping techniques '01; workshop proceedings; May 20-23, 2001, Tuscaloosa, Alabama","interactions":[],"lastModifiedDate":"2012-02-02T00:09:06","indexId":"ofr01223","displayToPublicDate":"2002-04-01T00:00:00","publicationYear":"2001","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2001-223","title":"Digital mapping techniques '01; workshop proceedings; May 20-23, 2001, Tuscaloosa, Alabama","language":"ENGLISH","doi":"10.3133/ofr01223","usgsCitation":"Soller, D.R., 2001, Digital mapping techniques '01; workshop proceedings; May 20-23, 2001, Tuscaloosa, Alabama: U.S. Geological Survey Open-File Report 2001-223, 248 p., https://doi.org/10.3133/ofr01223.","productDescription":"248 p.","costCenters":[],"links":[{"id":2760,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/of01-223/ ","linkFileType":{"id":5,"text":"html"}},{"id":160767,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2001/0223/report-thumb.jpg"},{"id":59805,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0223/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a96e4b07f02db65ac2d","contributors":{"authors":[{"text":"Soller, David R. 0000-0001-6177-8332 drsoller@usgs.gov","orcid":"https://orcid.org/0000-0001-6177-8332","contributorId":2700,"corporation":false,"usgs":true,"family":"Soller","given":"David","email":"drsoller@usgs.gov","middleInitial":"R.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":5061,"text":"National Cooperative Geologic Mapping and Landslide Hazards","active":true,"usgs":true}],"preferred":true,"id":206366,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":31564,"text":"ofr01432 - 2001 - Lahar hazards at Agua volcano, Guatemala","interactions":[],"lastModifiedDate":"2013-11-22T13:29:20","indexId":"ofr01432","displayToPublicDate":"2002-04-01T00:00:00","publicationYear":"2001","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2001-432","title":"Lahar hazards at Agua volcano, Guatemala","docAbstract":"At 3760 m, Agua volcano towers more than 3500 m above the Pacific coastal plain to the south and 2000 m above the Guatemalan highlands to the north.
