How many earthquakes over magnitude 8 were recorded in 1978?
In 1978, there were two earthquakes recorded with a magnitude over 8. One occurred in the Fiji region on September 12 with a magnitude of 8.1, and the other in the Andreanof Islands, Alaska on March 9 with a magnitude of 8.2.
What would a magnitude 10 earthquake do?
While a magnitude 9 could cause extensive damage, a magnitude 10 is almost unimaginable. There would be so much pressure on the Earth's crust that it would crack, causing uncountable volcanic eruptions, tsunamis, and unrepairable damage. A possible 900000 or more deaths would occur.
What was the worst earthquake that has happened to the US?
The worst US earthquake in terms of impact on people was probably the 1906 San Francisco Earthquake which is estimated to have led to the deaths of over 3,000 people and to have left between 227,000 and 300,000 people homeless out of a population of 410,000. In terms of magnitude, the worst earthquake in recorded US history was the 1964 Alaska earthquake which had a moment magnitude of 9.2. This makes it the most powerful earthquake recorded in the US and Canada and the second most powerful earthquake recorded on Earth by seismometer.
How long do after shocks happen after an earthquake?
By this you could mean 2 things:How long after the main earthquake do aftershocks occur?A: This depends on the magnitude of the main quake, and the faultline and how much tension there is between the tectonic plates.2. For how long after the main earthquake do aftershocks occur?A: This again depends on the magnitude of the main earthquake and the faultline.
