I propose to reduce the number of states/provinces named in the first sentence of the Impact section. The study suggested that the added information about East Coast earthquakes may prompt a revision of equations that predict ground shaking. The shaking was Groundwater level changes (most <15 cm) were recorded at 48 wells as far as 550km from the epicenter, and the 40 3-component seismometers and 200 1-component seismometers, which were all deployed within about one week after the mainshock, provided the best-recorded aftershock sequence ever in the eastern U.S.No evidence of surface rupture has been found, but there were small sand boils identified near the epicenter caused by strong shaking as well as rock falls up to 245 km away. Is it worth including? Scientists who study eastern and central North America earthquakes often work from the hypothesis that modern earthquakes occur as the result of slip on pre-existing faults that were formed in earlier geologic eras and that have been reactivated under the current stress conditions. An earthquake with a preliminary magnitude of 5.9 struck Tuesday near the nation's capital and sent shock waves up and down the East Coast Ivtv 19:52, 23 August 2011 (UTC) The USGS is reporting that the earthquake was magnitude 5.8: [1] Ioeth ( talk contribs twinkle ) 19:53, 23 August 2011 (UTC) Because it wasn't. (Public domain. The lede says "No injuries or deaths were reported".
In fact two buildings in Baltimore collapsed due to the earthquake.
--Do we really need a list? It seems like Wiki[edia is turning into a place for the gossipy yentas to throw up a page that gets edited and re-edited. Right now the intro is the geology section, and the rest of the article concerns reports of the aftermath. This is one of the strongest earthquakes felt in the East Coast in history. However, they were mistaken and, after that initial report, it was never again reported that the Pentagon was evacuated.
Reported experiences for this earthquake provided data that can be used to more accurately estimate the shaking distribution from moderate-to-large future earthquakes in this area, as well as help us better estimate the magnitudes of older historical events with fewer historical accounts.
On average eyewitnesses hit the website 90s after the ground start shaking. Geology of the Piedmont The earthquake occurred in the Piedmont, a region of complex geology that is the metamorphic core of the Appalachian Mountain system. Shaking intensity variation can be due to propagation path effects, source directivity, and/or site...Nearly 1 year ago, on 23 August, tens of millions of people in the eastern United States and southeastern Canada were startled in the middle of their workday (1:51 P.M. local time) by the sudden onset of moderate to strong ground shaking from a rare magnitude (M) 5.8 earthquake in central Virginia. According to the U.S. Geological Survey, the epicenter of the quake was located near Cuckoo, in Louisa County. Extraordinary distance limits of landslides triggered by the 2011 Mineral, Virginia, earthquake; 2012; Article; Journal; Bulletin of the Seismological Society of America; Jibson, Randall W.; Harp, Edwin L. )Unlike California, which is situated on the western edge of the North American plate grinding along the very active San Andreas fault, the East Coast of the U.S. is on part of the North American tectonic plate that has been relatively passive during recent geologic time. I'm thinking not, but I have the source if it's deemed worthwhile. The 5.8 magnitude earthquake, which originated in Virginia, brought panic to the Pentagon and the White House, and sparked fears that the iconic Washington Monument would fall. Also, airport delays could be added?
