Earthquake, either causing the event
or caused by the event (measured
using the Moment Magnitude
Intensity or Mercalli Scale)
There are also multiple types of
landslides:
Falls: A mass detaches from a steep
slope or cliff and descends by free-
fall, bounding, or rolling
Topples: A mass tilts or rotates
forward as a unit
Slides: A mass displaces on one or
more recognizable surfaces, which
may be curved or planar
Flows: A mass moves downslope
with a fluid motion. A significant
amount of water may or may not be
part of the mass
Like flooding, landslides are unique in
how they affect different geographic,
topographic, and geologic areas.
Therefore, consideration of a multitude
of measurements is required to
determine the severity of the landslide
event.
Lightning Activity Level:
Level 1
Level 2
Level 3
Level 4
Level 5
Level 6
For full definitions of Lightning Activity
Level, see Section 3.5 Vulnerability by
Hazard
Depth of snow ina given time frame
(ex. 2 or more inches per hour over a 12-
hour period)
Blizzard—violent snowstorm with
minimum winds of 35 mph and visibility
less than % mile for 3 hours
Ground snow load factor
Ice Storm—Sperry-Piltz Ice
Accumulation Index:
o—little impact
5—catastrophic damage to exposed
utility systems
For full definitions of Sperry-Piltz Ice
Accumulation Index, see Section 3.5
Vulnerability by Hazard
Geomagnetic Storms:
Gs—Extreme
G4—Severe
G3—Strong
G2—Moderate
G1a—Minor
Solar Radiation Storms:
Smoke and fire damage to structures
Disruption to power lines, traffic
control systems, and communications
Damage to critical electronic
equipment
Injury or death to people involved in
outdoor activity
Disruption to road network
Damage to trees and power lines,
communications, gas lines
Structural damage to roofs/collapse.
Increase in CO, other hazards
Space weather can produce
electromagnetic fields that induce
currents in wires, disrupting power
lines and causing widespread power
outages
