This document defines several natural disasters and weather events: a tsunami caused by an earthquake or volcanic eruption under the sea; an earthquake from movement along a fault line or volcanic activity; a hurricane or tropical cyclone with heavy rain and winds between 73-136 knots; soil erosion from flowing water; and global warming or climate change from an increase in the average temperature of the earth's atmosphere.

2. A cataclysm
resulting from a
destructive sea
wave caused by an
earthquake or
volcanic

3. Shaking and
vibration at the
surface of the
earth resulting
from underground
movement along a
fault plane of from
volcanic activity

4. A severe tropical
cyclone usually
with heavy rains
and winds moving
a 73-136 knots
(12 on the
Beaufort scale)

5. The washing
away of soil by
the flow of
water

6. An increase in the
average
temperature of the
earth's atmosphere
(especially a
sustained increase
that causes climatic
