hazard (in risk equation)
(0-100% damaging capacity) x (hazard frequency). How damaging would a particular hazard be? How often does this occur?
geophysical or geological hazard. Rapid onset events (occur quite quickly), does not include slower-acting geophysical processes (environmental degradation, desertification, etc.), NOR human-generated or biological hazards (nuclear meltdowns, cholera epidemics, etc.)
