Ground swell, a sort of foreunner jolt or warning shock- then the major ground wave tremor. there are also after shocks in many quakes, so we have a number of potentially destructive seismic waves.
It is called a tremor.
A small earthquake that happens after a larger one is called an aftershock. Aftershocks happen because the crust in the area where the main earthquake happened is adjusting to the earthquake's effects.
No, they can't tell that it is a foreshock until a larger earthquake happens. (The largest main earthquake is called the mainshock)
An earthquake is the movement of the tectonic plates, the little quake that happens after the main quake is called the aftershock.Aftershocks. If an aftershock is stronger than the original earthquake, it takes its place and trhe last earthquake becomes a pre-shock.
Most small earthquakes are just background seismicity. There is no way to tell whether a small event will be followed by a larger one. But if there is a larger earthquake afterwards, the first earthquake is called a "foreshock"
Yes, earthquakes can have foreshocks, which are smaller earthquakes that occur before the main event. These foreshocks can help seismologists to predict the likelihood and intensity of an upcoming larger earthquake.
An aftershock is an earthquake that comes after another, larger earthquake often within a few days.
The larger the magnitude of the earthquake, the larger the energy to be released by the earthquake.
It's a smaller (or sometimes larger) earthquake after the main earthquake
Fertilization
The amplitude of a magnitude 8 earthquake is 100 times larger than a magnitude 6 earthquake.
