East Coast: Historically, no tsunamis have been generated on the east coast, a consequence of the low level of seismic activity and the lack of vertical fault
Earthquakes, volcanism, and hydrothermal features go hand in hand at Yellowstone. The underground plumbing of hot water and magmas beneath Yellowstone is influenced by the same stresses that cause earthquakes.
It isn't that simple. There is not one magnitude above which damage will occur.
On January 19, 1968, a thermonuclear test, codenamed Faultless, took place in the Central Nevada Supplemental Test Area. The codename turned out to be a poor choice of words because a fresh fault rupture some 1200 meters long was produced.
No. Neither the USGS nor any other scientists have ever predicted a major earthquake. They do not know how, and they do not expect to know how any time in the foreseeable future.
To view a map of latest earthquakes or report a felt earthquake, check the Real-time Earthquake Map. Make sure you're Control Panel settings are allowing you to see earthquakes of all magnitudes
No. Of more than 150,000 Class II injection wells in the United States, roughly 40,000 are waste fluid disposal wells for oil and gas operations.
How are earthquakes recorded? How are earthquakes measured? How is the magnitude of an earthquake determined?
Earthquakes are recorded by a seismographic network. Each seismic station in the network measures the movement of the ground at the site. The slip of one block of rock over another in an earthquake releases energy that makes the ground vibrate.

How much energy was released by the magnitude 9.0 earthquake off the west coast of northern Sumatra?
Es 20X10^17 Joules, or 475,000 kilotons (475 megatons) of TNT, or the equivalent of 23,000 Nagasaki bombs.
