What would a 10 on the Richter scale do?

The Richter Scale is logarithmic, meaning it goes up by levels of ten, so a magnitude 10 earthquake is 10 times larger than a magnitude 9. That’s the only place that I could think of that could trigger such a quake. This is really bad, because this means that we get violent shaking over a really wide area.

What is the Richter magnitude of the strongest earthquakes?

The largest recorded earthquake was the Great Chilean earthquake of May 22, 1960, which had a magnitude of 9.5 on the moment magnitude scale. The larger the magnitude, the less frequently the earthquake happens.

How long does a 7.0 earthquake last?

Generally, only seconds. Strong ground shaking during a moderate to large earthquake typically lasts about 10 to 30 seconds. Readjustments in the earth cause more earthquakes (aftershocks) that can occur intermittently for weeks or months.

What is the atomic bomb equivalent to a 7.0 earthquake?

A magnitude 4.0 earthquake is only equivalent to about 6 tons of TNT explosives, but because the Richter scale is a base-10 logarithmic scale, the amount of energy released increases quickly: A magnitude 5.0 earthquake is about 200 tons of TNT, magnitude 6.0 is 6,270 tons, 7.0 is 199,000 tons, 8.0 is 6,270,000 tons,

Can you see earthquakes from space?

Because Earthquakes are just small vibrations by the tectonic plates. Only a part of the earth is experiencing tremors. With naked eye observations it is unlikely that you can detect an earthquake from space. However you may be abe to see the devastation of cities or massive fires started as a consequence of the quake.
