Question

Which of the following statements about earthquakes is true?
A.
The date of future earthquakes cannot be precisely predicted.
B.
Earthquakes occur at regular intervals, usually every five years.
C.
Earthquakes can only occur on dry land or under water at depths less than 100 meters.
D.
Earthquakes and volcanic eruptions always occur at the same time.

Answer 1

A.

Explanation: Scientists can estimate where earthquakes are likely and the probability over years, but they cannot precisely predict the exact date and time of a future quake. Options B, C and D are false (quakes are not strictly periodic, can occur at great depths and under the sea, and do not always coincide with volcanic eruptions).
