An earthquake – also called a quake, tremor, or temblor – is the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity , from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage ...
Logo of the ANSS. The Advanced National Seismic System (ANSS) is a collaboration of the United States Geological Survey (USGS) and regional, state, and academic partners that collects and analyzes data on significant earthquakes to provide near real-time (generally within 10 to 30 minutes [1]) information to emergency responders and officials, the news media, and the public.

According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and ...
Páll Einarsson. 100 earthquakes hit Iceland since midnight. 09:11, Lydia Patrick. The strongest earthquake with a magnitude of 3.35 hit Vatnafjoll in South Iceland this morning at 5.56am, report ...
As Iceland has experienced a seismic swarm of 30,000 earthquakes in the last three weeks, Lydia Patrick maps which areas have been hit by the worst of the tremors:
A pie chart comparing the seismic moment release of the three largest earthquakes for the hundred-year period from 1906 to 2005 with that for all earthquakes of magnitudes <6, 6 to 7, 7 to 8, and >8 for the same period. The 2011 Japan quake would be roughly similar to Sumatra. Earthquakes of magnitude 8.0 and greater from 1900 to 2018.
Almost 100 earthquakes shook Iceland from midnight today, as the country remains apprehensive about an imminent eruption.. The strongest earthquake with a magnitude of 3.35 hit Vatnafjoll in South ...
The map and accompanying study offer precise information about the regions most at risk of earthquakes, and which types of quakes are likely to occur. The scientists also learned more about places ...
