Wabash Valley Seismic Zone
The Wabash Valley Seismic Zone (also known as the Wabash Valley Fault System or Zone) is a tectonic region located in the Midwest of the United States, centered on the valley of the Lower Wabash River, along the state line between southeastern Illinois and southwestern Indiana. Geology The Wabash Valley Seismic Zone consists largely of vertically oriented ("normal") faults deeply buried under layers of sediment. Although the tectonics of the region are still not fully understood and are the subject of ongoing research, these faults are thought by some to be associated with a branch of the New Madrid aulacogen, an old rift zone where the lithosphere actively began to pull apart at perhaps two separate times in the distant past. Present-day GPS measurements show that the region deforms at about 1–2 mm/yr with compression along the Wabash Valley Fault Zone, and extension in SW Indiana. The crust in the area has been weakened by the numerous faults, which remain active sites ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Andreas Fault
The San Andreas Fault is a continental transform fault that extends roughly through California. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal). The fault divides into three segments, each with different characteristics and a different degree of earthquake risk. The slip rate along the fault ranges from /yr. It was formed by a transform boundary. The fault was identified in 1895 by Professor Andrew Lawson of UC Berkeley, who discovered the northern zone. It is often described as having been named after San Andreas Lake, a small body of water that was formed in a valley between the two plates. However, according to some of his reports from 1895 and 1908, Lawson actually named it after the surrounding San Andreas Valley. Following the 1906 San Francisco earthquake, Lawson concluded that the fault extended all the way into southern California. In 1953, geologist Thomas Dibblee ...

West Salem, Illinois
West Salem is a village in Edwards County, Illinois, United States. The population was 786 at the 2020 census, down from 897 at the 2010 census. History The West Salem area was settled in the 1830s and early 1840s by Moravians primarily from Salem, North Carolina, and Hope, Indiana. Among the early settlers were Adam Hedrick and Peter Hinkle. From 1841 to 1846 the new Moravian settlers were working with the headquarters of the southern province of the Moravian Church in Salem (Old Salem), North Carolina, in establishing a congregation. William Eberman, the Moravian pastor at Hope, Indiana, was sent to visit and preach for them in the fall of 1841. Many other settlers followed, until by 1843, more than 80 families lived within a radius of what was to become West Salem, most of them Moravians. But in 1843, it was Martin Hauser, a Moravian home missionary also from Hope, Indiana, who would be instrumental not only in starting a Moravian Church, but also in helping to establish ...

Epicenter
The epicenter, epicentre () or epicentrum in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates. Surface damage Before the instrumental period of earthquake observation, the epicenter was thought to be the location where the greatest damage occurred, but the subsurface fault rupture may be long and spread surface damage across the entire rupture zone. As an example, in the magnitude 7.9 Denali earthquake of 2002 in Alaska, the epicenter was at the western end of the rupture, but the greatest damage was about away at the eastern end. Focal depths of earthquakes occurring in continental crust mostly range from . Continental earthquakes below are rare whereas in subduction zone earthquakes can originate at depths deeper than . Epicentral distance During an earthquake, seismic waves propagate in all directions from the hypocenter. Seismic shadowing occurs on the opposite s ...

Aftershock
In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to a consistent pattern. In some earthquakes the main rupture happens in two or more steps, resulting in multiple main shocks. These are known as doublet earthquakes, and in general can be distinguished from aftershocks in having similar magnitudes and nearly identical seismic waveforms. Distribution of aftershocks Most aftershocks are located over the full area of fault rupture and either occur along the fault plane itself or along other faults within the volume affected by the strain associated with the main shock. Typically, aftershocks are found up to a distance equal to the rupture length away from the fault plane. The patte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
