Draft:List of Magnitudes for Natural Disasters

From Wikipedia, the free encyclopedia

This is a list of magnitudes for natural disasters like Earthquakes

Magnitude -15

[edit]

Equates to the amount of a piece of dust falling off a table[1]

Piece of dust

Magnitude -8

[edit]
Grain of sand

A grain of sand falling from a hourglass[1]

Magnitude -7

[edit]

A feather falling to the ground[1]

Magnitude -6

[edit]

A key press on a light keyboard[1]

Magnitude -5

[edit]

A key press on a IBM Model M mechanical keyboard[1]

Magnitude -4

[edit]

A penny falling off a dog[1]

Magnitude -3

[edit]

A cat pushing your phone off a table[1]

Magnitude -2

[edit]

A cat falling off a table[1]

Magnitude -1

[edit]

A football player[1]

Magnitude 0

[edit]

A football team running into your neighbors garage [1]

Magnitude 1

[edit]

A partially loaded cement truck falling[1]

Magnitude 2

[edit]

Felt slightly by some people. No damage to buildings.

Magnitude 3

[edit]

Often felt by people, but very rarely causes damage. Shaking of indoor objects can be noticeable.

Magnitude 4

[edit]

Noticeable shaking of indoor objects and rattling noises. Felt by most people in the affected area. Slightly felt outside. Generally causes zero to minimal damage. Moderate to significant damage is very unlikely. Some objects may fall off shelves or be knocked over.

Magnitude 5

[edit]

Can cause damage of varying severity to poorly constructed buildings. Zero to slight damage to all other buildings. Felt by everyone.

Magnitude 6

[edit]

Damage to a moderate number of well-built structures in populated areas. Earthquake-resistant structures survive with slight to moderate damage. Poorly designed structures receive moderate to severe damage. Felt in wider areas; up to hundreds of kilometers from the epicenter. Strong to violent shaking in the epicentral area.

Magnitude 7

[edit]

Causes damage to most buildings, some to partially or completely collapse or receive severe damage. Well-designed structures are likely to receive damage. Felt across great distances with major damage mostly limited to 250 km from the epicenter.

Magnitude 8

[edit]

Major damage to buildings, and structures likely to be destroyed. Will cause moderate to heavy damage to sturdy or earthquake-resistant buildings. Damaging in large areas. Felt in extremely large regions.

Magnitude 9

[edit]

Near total destruction – severe damage or collapse to all buildings. Heavy damage and shaking extend to distant locations. Permanent changes in ground topography.
