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 ...
Explosion of unserviceable ammunition and other military items The explosion of the Castle Bravo nuclear bomb. An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be ...
This then becomes an earthquake once triggered by a nuclear explosion in the epicenter or a vast electric pulse. [2] While a nuclear explosion can trigger an earthquake within a few tens of kilometers, earthquakes induced by explosions have been much smaller than the explosion. [3]
The earthquake bomb, or seismic bomb, was a concept that was invented by the British aeronautical engineer Barnes Wallis early in World War II and subsequently developed and used during the war against strategic targets in Europe. [1]
Earthquakes occur when two plates suddenly slip past each other, setting off seismic waves that cause the planet's surface to shake, according to the USGS. What is an earthquake, scientifically ...
An underground explosion concentrates this pressure wave, and a localized earthquake event is more probable. The first and fastest wave, equivalent to a normal earthquake's P wave , can inform the location of the test; [ 23 ] the S wave and the Rayleigh wave follow.
California has hundreds of active faults.
Friday’s earthquake was mild compared with some felt in California or the Caribbean, rating at 4.8 on the Richter scale. But “it’s pretty big for the Northeast,” said Joshua Russell, who ...
