The Quick Search form is very simple with only four search options available. If you expect that your search will result in a large number of results (more than 40), you can reduce the amount of time to obtain those results by limiting the number of results on each page at the bottom of the search form. Damage occurred as far away as Washington, D.C., and Charleston, S.C. The additional geographic search options are AMS sheet and physiographic province. Subsequent state-scale compilations, such as those by Johns and others, (1982), Stickney and Bartholemew (1987), and Hecker (1993) provided some supporting database and were the first true fault compilations. This numeric identifier allows us to clearly cite multiple-same year publications for authors.

In a first of its kind study U.S. Geological Survey (USGS) and Duke University seismologists have used tiny "microearthquakes" along a section of California’s notorious San Andreas Fault to create unique images of the contorted geology scientists will face as they continue drilling deeper into the fault zone to construct a major earthquake "observatory. http://scedc.caltech.edu/recent/ and also why all fault lines in California missing? Most recently, in 2018 it was revised again to 2.58 Myr, see GSA Geologic Time Scale. These fault segments are given a different value for name, number, code, or dip direction and so in the database each segment occurs as its own unique entity. […], […] And it was a very loud fart as 3 explosion-like loud booms were reported. A strike-slip fault is when two blocks slip past one another, like the San Andreas Fault line. Ever since the great magnitude 9.2 earthquake shook Alaska 50 years ago today, scientists have suspected that the quake's rupture halted at the southwestern tip of Kodiak Island due to a natural barrier.

The data presented in the compilation are extensively referenced using the standard USGS reference style, with the exception of attaching a unique number to each cited reference for convenience. This Site Might Help You. The Advanced Search form allows queries on the above four parameters and on geographic options, paleoseismic characteristics, and structural characteristics. The U.S. Geological Survey has a new website that offers a virtual tour of the Hayward fault. This map was created by a user. This map is a progress report.
