Where can I find photographs of earthquake damage?
Two sources for photographs that show earthquake damage are:
U.S. Geological Survey Photographic Library (see 'earthquakes' in the categories left column)
Steps to identification of a sonic boom:
The USGS sees either nothing on our seismic records or a fairly short high-frequency signal that doesn't look like an earthquake.
On rare occasions, we see the event on multiple stations, and the time difference between stations matches the speed of
Phenomena such as sheet lightning, balls of light, streamers, and steady glows, reported in association with earthquakes are called earthquake lights (EQL). Geophysicists differ on the extent to which they think that individual reports of unusual lighting near the time and epicenter of an earthquake actually represent EQL...Read Full Answer
There is nothing different about a cave that would make it immune to the shaking from an earthquake. Just as there are safer and less safer places to be on the surface of the earth during an earthquake, there are also various characteristics inside caves that make some cave locations safer or less safe than others. First...Read Full Answer
Why do earthquakes in other countries seem to cause more damage and casualties than earthquakes in the U.S.?
There is more damage and more deaths from earthquakes in other parts of the world primarily because of buildings which are poorly designed and constructed for earthquake regions, and population density.Read Full Answer
Groundwater levels in wells may oscillate up and down while seismic waves pass, and in some cases, the water level may remain higher or lower for a period of time after the seismic wavetrain has ended.Read Full Answer
"Booms" have been reported for a long time, and they tend to occur more in the Northeastern US and along the East Coast. Of course, most "booms" that people hear or experience are actually some type of cultural noise, such as some type of explosion, a large vehicle going by, or sometimes a sonic boom, but there have been...Read Full Answer
The way an earthquake feels depends on where you are, where the earthquake is, and how big the earthquake is:
A large earthquake nearby will feel like a sudden large jolt followed quickly by more strong shaking that may last a few seconds or up to a couple of minutes if it's a rare great event. The shaking
The U.S. Geological Survey has released two new videos about the Great Alaska Earthquake of March 27, 1964 to commemorate the upcoming 50th anniversary of the largest earthquake ever recorded in the United States. The videos include rare vintage film footage and photos of the earthquake damage, combined with modern interviews with some of the same scientists who first investig
To commemorate the upcoming 50th anniversary of the largest earthquake ever recorded in the United States, the U.S. Geological Survey has reissued a series of landmark reports covering the results of investigations of the Great Alaska Earthquake of March 27, 1964.

Meeting the challenge of the Loma Prieta earthquake: 20 years of scientific and technological advances
On October 17, the San Francisco Bay Area will be marking the 20th anniversary of the 1989 Loma Prieta earthquake -- the Bay Area's most significant and destructive earthquake during recent times. As part of the anniversary commemoration, the U.S. Geological Survey is holding an evening public lecture about scientific and technological advances in earthquake studies achieved since 1989.
The U.S. Geological Survey (USGS) will release an on-line virtual tour of the 1906 earthquake on Thursday, April 6, that will offer the public an opportunity to interactively view both historic information and up-to-the-minute science and hazard information on the most damaging earthquake in U.S. history.
Eyewitness accounts of the 1906 earthquake in San Francisco agree on a number of striking points, according to Jack Boatwright of the U.S. Geological Survey.
About 10 strong earthquakes have struck southern Illinois and Indiana during the past 12,000 years, according to a new study by geologist Steve Obermeier of the U.S. Geological Survey and archeologists Pat Munson and Rex Garniewicz of Indiana University.
"1964 Quake: The Great Alaska Earthquake" is an eleven minute video highlighting the impacts and effects of America's largest recorded earthquake. It is an expanded version of the four minute video "Magnitude 9.2". Both were created as part of USGS activities acknowledging the fifty year anniversary of the quake on March 27, 2014. The video features USGS geologist George Plafker, who, in the 1960's, correctly interpreted the quake as a subduction zone event. This was a great leap forward in resolving key mechanisms of the developing theory of plate tectonics. Landslide impacts and the extreme tsunami threat posed by these quakes are also discussed. Loss of life and destruction from the earthquake and accompanying tsunamis was the impetus for things like the NOAA Tsunami Warning Centers and the USGS Earthquake Hazards Program.
The May 12, 2008, Great Sichuan Earthquake, also called the Wenchuan Earthquake, occurred at 14:28 local time, in Sichuan Province, China. The earthquake magnitudes were Mw = 7.9 (USGS), Ms = 8.0 (Chinese Earthquake Administration). The epicenter was 80 km west-northwest of Chengdu, the capital city of Sichuan province. Damage by earthquake-induced landslides was catastrophic and accounted for many of the casualties. This photo is of the town of Qushan, Beichuan County, China, destroyed by strong shaking and catastrophic landslides. This photo was taken after deadly debris flows had recently impacted the area.

Ground view of collapsed building and burned area at Beach and Divisadero Streets, Marina District, San Francisco, following the October 17, 1989 Loma Prieta earthquake. At 5:04:15 p.m. (PDT), the magnitude 6.9 (moment magnitude; surface-wave magnitude, 7.1) earthquake severely shook the San Francisco and Monterey Bay regions. The epicenter was located at 37.04° N. latitude, 121.88° W. longitude near Loma Prieta peak in the Santa Cruz Mountains, approximately 14 km (9 mi) northeast of Santa Cruz and 96 km (60 mi) south-southeast of San Francisco.
The corner of the building collapsed into rubble.
This photograph, taken by George Lawrence from a series of kites five weeks after the great earthquake of April 18, 1906, shows the devastation brought on the city of San Francisco by the quake and subsequent fire. The view is looking over Nob Hill toward business district, South of the Slot, and the distant Mission. The Fairmont Hotel, far left. dwarfs the Call Building. (photo courtesy of Harry Myers).
Extensive damage to buildings and roads, and large boats washed far ashore, provide valuable information to tsunami researchers. Here, in Natori, Japan, south of Sendai, the height of damage indicates that the water flow from the tsunami wave was about 10 meters (33 feet).
