Earthquake magnitudes were redetermined as necessary to make them as consistent as possible with the Gutenberg methods and results, which make up much of the data base. Measurement errors were estimated for the three variables for 58 moderate to large shallow-focus earthquakes. Regression analyses were then made utilizing the estimated measurement errors.</p><p>The regression analysis demonstrates that the relations among the variables magnitude, length, and displacement are stochastic in nature. The stochastic variance, introduced in part by incomplete surface expression of seismogenic faulting, variation in shear modulus, and regional factors, dominates the estimated measurement errors. Thus, it is appropriate to use ordinary least squares for the regression models, rather than regression models based upon an underlying deterministic relation in which the variance results primarily from measurement errors.</p><p>Significant differences exist in correlations of certain combinations of length, displacement, and magnitude when events are grouped by fault type or by region, including attenuation regions delineated by Evernden and others.</p><p>Estimates of the magnitude and the standard deviation of the magnitude of a prehistoric or future earthquake associated with a fault can be made by correlating&nbsp;<i>M<sub>s</sub></i>&nbsp;with the logarithms of rupture length, fault displacement, or the product of length and displacement.</p><p>Fault rupture area could be reliably estimated for about 20 of the events in the data set.

Intracanyon basalt flows record a granite canyon successively filled by lava and then recut at least five times in the last 2 million years. The most voluminous flow, Steamboat Rock Basalt, reached 60 kilometers downstream and spread out on the Snake River Plain just east of Boise. Lavas that reached the river were erupted from vents bordering the main canyon and adjacent tributaries. The river canyon was periodically flooded by basalt from these eruptions, reentrenched to a new lower level, then flooded again. This succession resulted in terraces of older flows high above the river and of younger flows lower on the canyon walls. The canyon-filling flows dammed the river and created deltas of pillow basalt and hyaloclastite overlain by massive subaerial basalt. Foreset beds in the hyaloclastite deposits and inclined pillows indicate flow into reservoirs behind the lava dams. A well-documented example of a lava dam is the one formed by the Smith Prairie Basalt, which is about 0.2 million years old. Potassium-argon ages calibrate a canyon history in which the river was lowered at a rate between 0.005 and 0.01 centimeter a year over the last 2 million years. The lava dams interrupted this lowering but were each rapidly incised in about a quarter of a million years at rates averaging 0.03 to 0.07 centimeter a year. </p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Cenozoic geology of Idaho","language":"English","publisher":"Idaho Bureau of Mines and Geology","publisherLocation":"Moscow, ID","usgsCitation":"Howard, K.A., Shervais, J.W., and McKee, E., 1984, Canyon-filling lavas and lava dams on the Boise River, Idaho, and their significance for evaluating downcutting during the last 2 million years, 13 p.","productDescription":"13 p.","startPage":"629","endPage":"641","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":355843,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":355842,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.idahogeology.org/product/b-26"}],"country":"United States","state":"Idaho","otherGeospatial":"Boise River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -116.54296874999999,\n              42.94033923363181\n            ],\n            [\n              -114.202880859375,\n              42.94033923363181\n            ],\n            [\n              -114.202880859375,\n              44.28453670601888\n            ],\n            [\n              -116.54296874999999,\n              44.28453670601888\n            ],\n            [\n              -116.54296874999999,\n              42.94033923363181\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"editors":[{"text":"Bonnichsen, Bill","contributorId":94358,"corporation":false,"usgs":true,"family":"Bonnichsen","given":"Bill","email":"","affiliations":[],"preferred":false,"id":740566,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Breckenridge, R.M.","contributorId":206461,"corporation":false,"usgs":false,"family":"Breckenridge","given":"R.M.","email":"","affiliations":[],"preferred":false,"id":740567,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Howard, Keith A. 0000-0002-6462-2947 khoward@usgs.gov","orcid":"https://orcid.org/0000-0002-6462-2947","contributorId":3439,"corporation":false,"usgs":true,"family":"Howard","given":"Keith","email":"khoward@usgs.gov","middleInitial":"A.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":740563,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shervais, John W.","contributorId":57753,"corporation":false,"usgs":true,"family":"Shervais","given":"John","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":740564,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McKee, E.H.","contributorId":20736,"corporation":false,"usgs":true,"family":"McKee","given":"E.H.","email":"","affiliations":[],"preferred":false,"id":740565,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
