You can put this solution on YOUR website! The intensity if the Columbia Earthquake was measured to be > 8.8 on a Richter Scale
On a Mercalli scale this is termed as a "GREATER CASTASTROPHE". It is describes as: Almost everything is destroyed. Objects are thrown into the air. The ground moves in waves or ripples. Large amounts of rock may move.
Earthquake Severity:
Richter magnitude and earthquake effects
less than 3.5 --> Generally not felt, but recorded.
3.5 - 5.4 --> Often felt, but rarely causes damage.
under 6.0 --> At most slight damage to well-designed buildings. Can
cause major damage to poorly constructed buildings over small regions.
6.1 - 6.9 --> Can be destructive in areas up to about 100 kilometers
across where people live.
7.0 - 7.9 --> Major earthquake. Can cause serious damage over larger
areas.
8 or greater --> Great earthquake. Can cause serious damage in areas
several hundred kilometers across.
Magnitude Richter --> TNT equivalent
-1.5 --> 6 ounces
1 --> 30 ounces
1.5 --> 320 pounds
2 --> 1 ton
2.5 --> 4.6 tons
3 --> 29 tons
3.5 --> 73 tons
4 --> 1000 tons
4.5 --> 5100 tons
5 --> 32000 tons
5.5 --> 80000 tons
6 --> 1 milion tons
6.5 --> 5 milion tons
7 --> 32 milon tons
7.5 --> 160 milion tons
8 --> 1 bilion tons
8.5 --> 5 bilion tons
9 --> 32 bilion tons
10 --> 1 trilion tons
12 --> 160 trilion tons
