A measurement of 100 on the Richter scale is absurd. Since the scale is logarithmic, each unit increase is 10 times larger than the previous. So a 9.0 is ten times greater in power than an 8.0. Humans have never experienced an earthquake larger than a 9.5. An earthquake at 100 Richter would be 1091 times stronger than a 9.0, which makes no sense (I doubt there is enough energy in the earth to create such a force).

The chart below shows the energy yield of an earthquake in equivalent TNT weight. Looks like a 12 would theoretically tear the earth apart.

Richter TNT for Seismic Example

Magnitude Energy Yield (approximate)

-1.5 6 ounces Breaking a rock

1.0 30 pounds Large Blast at a Construction Site

1.5 320 pounds

2.0 1 ton Large Quarry or Mine Blast

2.5 4.6 tons

3.0 29 tons

3.5 73 tons

4.0 1,000 tons Small Nuclear Weapon ( 1 kiloton)

4.5 5,100 tons Average Tornado (total energy)

5.0 32,000 tons

5.5 80,000 tons Little Skull Mtn., NV Quake, 1992

6.0 1 million tons Double Spring Flat, NV Quake, 1994

6.5 5 million tons Northridge, CA Quake, 1994

7.0 32 million tons Hyogo-Ken Nanbu, Japan Quake, 1995; Largest Thermonuclear Weapon

7.5 160 million tons Landers, CA Quake, 1992

8.0 1 billion tons San Francisco, CA Quake, 1906

8.5 5 billion tons Anchorage, AK Quake, 1964

9.0 32 billion tons Chilean Quake, 1960

10.0 1 trillion tons (San-Andreas type fault circling Earth)

12.0 160 trillion tons (Fault Earth in half through center,

OR Earth's daily receipt of solar energy)
