WHAT HAVE YOU LEARNED ABOUT EARTHQUAKES AND EARTHQUAKE PREDICTION?

Earthquakes can’t be fully predicted right now but we can estimate when a new one will occur. For example, scientists think there’s a 2%, 10%, or 50% chance of an earthquake occurring in the San Andres fault. But scientists think they will be able to predict earthquakes soon.

WHAT FACTORS INFLUENCE EARTHQUAKE PREDICTION?

Movement of the plates Heat Past Earthquakes Type of boundary

WHERE ON EARTH DO MOST OF THE REALLY BIG EARTHQUAKES STRIKE?

Almost every big earthquake has occurred on convergent boundaries. For example, the recent Japan earthquake was on a convergent boundary. A few of the small ones also occurred on transform boundaries.
