What are the three types of earhquakes?
The three types of earthquakes are tectonic earthquakes, volcanic earthquakes, and collapse earthquakes. Tectonic earthquakes are the most common and are caused by the movement of earth's plates. Volcanic earthquakes occur in association with volcanic activity, while collapse earthquakes happen in underground mines and caverns.
Can an earthquake cause more earthquakes?
For the same place, yes, it is possible. This does not usually occur though, because most earthquakes will die off after a few minutes followed only by aftershocks. Once an earthquake occurs it causes and imbalance in the forces along nearby fault planes increasing the likelihood that those will also rupture. In this sense small earthquakes can trigger larger ruptures or vice versa. This is why it is sometimes possible to predict future large rupture from fore-shocks depending on the known recurrence interval and estimated built up stress.
Do earthquakes start at the epicenter?
Yes earthquakes start at the epicentre and in waves the energy ripples out across continents giving us the shaking feeling like an earthquake is happening.
