Richter Scale:
< 3.4 (detected only by
seismometers)
> 8 (total damage, surface waves
seen, objects thrown in air)
For full definitions of Richter Scale, see
Section 3.5 Vulnerability by Hazard
Extreme heat—period of 3 consecutive
days which air temperature reaches 9oF
or higher on each day.
Extreme cold—period of 3 consecutive
days of minimum temperatures at or
below oF
Enhanced Fujita Tornado Damage
Scale:
EFo—winds 65-85 mph
EFa—winds 86-110 mph
EF2—winds 111-135 mph
EF3—winds 136-165 mph
EF4—winds 166-200 mph
EFs5—winds over 200 mph
Disease epidemics
Large-scale incidents of food or water
contamination
Extended periods without adequate
sanitation services
While no universally accepted standard
or scientific scale has been developed
for measuring the severity of all
landslides, severity can be measured
several other ways:
Steepness/grade of the Slope
(measured as a percent)
Geographical Area
= Measured in square feet, square
yards, etc.
= More accurately measured using
LIDAR/GIS systems
Overall:
Loss of crops
Inadequate quantity of drinking
water
Loss of water for fire protection
Increased risk of fire
Structural damage or collapse of
buildings
Damage or loss of infrastructure,
including roads, bridges, railroads,
power and phone lines, City
communications, City radio system,
power generation facility, domestic
water, and wastewater treatment
plant
Loss of water for fire protection
Increased risk of fire from gas break
Risk to life, medical surge
Overburdened power systems may
experience failures due to extreme
heat
Shortages of heating fuel in extreme
cold due to high demand.
Medical surge
Loss of municipal water supply for
drinking water and fire protection due
to freezing temperatures
Wind damage to structures and trees
Damage or loss of infrastructure,
including roads, bridges, railroads,
power and phone lines, City
communications, City radio system,
power generation facility, domestic
water, and wastewater treatment
plant
Environmental hazards resulting from
damage
Medical surge
Loss of natural resources
Burden on healthcare facilities
Possible quarantine to prevent disease
from spreading.
