There's a 100 percent chance of an earthquake today.

Earthquakes are very common occurrences on this planet. So today -- somewhere -- an earthquake will occur.

It may be so light that only sensitive instruments will perceive its motion; it may shake houses, rattle windows, and displace small objects; or it may be sufficiently strong to cause property damage, injury, and death.

It is estimated that there are 500,000 detectable earthquakes in the world each year. 100,000 of those can be felt, and 100 of them cause damage.
