Is a 4.5 earthquake strong?

Events with magnitudes greater than 4.5 are strong enough to be recorded by a seismograph anywhere in the world, so long as its sensors are not located in the earthquake’s shadow. The following describes the typical effects of earthquakes of various magnitudes near the epicenter.

Is a 3.5 earthquake bad?

Earthquakes that fall between 3.0 to 3.9 on the scale are considered minor. We can feel the earthquake, and objects inside are going to shake around, but there very rarely is damage.

Is a 10.0 earthquake possible?

No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. … No fault long enough to generate a magnitude 10 earthquake is known to exist, and if it did, it would extend around most of the planet.

How far away can you feel a 9.0 earthquake?

In a place with complex geology, every rock contact scatters and absorbs seismic energy, so that far away you’d probably feel it but not see damage or casualties. In the U.S. Midcontinent, with layer-cake geology that makes efficient wave guides, a 9.0 event would probably produce appreciable damage 565 miles away.

What’s the longest earthquake ever recorded?
