It is one of the official regions in the Great ShakeOut Earthquake Drills movement. [1] The first drill, known as The Great Southern California ShakeOut, took place on November 13, 2008, [2] was the largest earthquake drill in U.S. history up until that time, and involved 5.3 million participants. [3] The Earthquake Country Alliance organized ...
The 1993 Scotts Mills earthquake, also known as the "Spring break quake", occurred in the U.S. state of Oregon on March 25 at 5:34 AM Pacific Standard Time. With a moment magnitude of 5.6 and a maximum perceived intensity of VII (Very strong) on the Mercalli intensity scale, it was the largest earthquake in the Pacific Northwest since the Elk ...
Quake (natural phenomenon) A quake is the result when the surface of a planet, moon or star begins to shake, usually as the consequence of a sudden release of energy transmitted as seismic waves, and potentially with great violence. The types of quakes include earthquake, moonquake, marsquake, venusquake, sunquake, starquake, and mercuryquake.

The 4.7-magnitude earthquake was felt as far as San Diego and north into the coast of Bakersfield. Seismologist Dr. Lucy Jones explains why some residents felt the earthquake while others didn't.
An earthquake struck the East Coast of the United States on Friday morning, according to the U.S. Geological Survey, causing buildings to shake and rattling nerves from Maryland to Maine.
Influenced by the monumental and permanent land art earthworks of the early 1970s, the installation was a conceptual feedback loop between the seismic activity of California and the mechanical reflection of these frequent seismic events which controlled the earthquake shake table. Each time an earthquake occurred an array of 5/8 inch steel rods ...
v. t. e. The Modified Mercalli intensity scale (MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth. (The " Mw ...
