What is a normal fault in science?
normal fault – a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.

| 7.0 to 7.9 | Major earthquake. Serious damage. | 20 |
| 8.0 or greater | Great earthquake. Can totally destroy communities near the epicenter. | One every 5 to 10 years |
What is the most dangerous type of fault?
Reverse faults, particularly those along convergent plate boundaries are associated with the most powerful earthquakes, megathrust earthquakes, including almost all of those of magnitude 8 or more. Strike-slip faults, particularly continental transforms, can produce major earthquakes up to about magnitude 8.
Do small earthquakes mean a big one is coming?
Small cluster of earthquakes may be warning sign of larger one to come, researcher says. Most earthquakes we feel come after smaller ones. That’s according to a new study as scientists try to predict when and where earthquakes might occur.
