Another cause of pestilence and famine is war and rumors of wars. Currently weather, crop failures, drought and finances are adding to the misery. But war is almost always a huge cause.

None of he above is usually reported in detail, especially with hard numbers to back up claims. :scratch

There was a 6.4 aftershock today. Now you know there are alot of biggies when we start ignoring a 6.4.

4 aftershocks today of magnitude 6.0+

Amazing, considering most aftershocks are in the 4-5 range and 6.0+ quakes are usually considered as seperate earthquakes

A 6+ on our west coast or anywhere in the US for that matter would be death and destruction. There have been so many bigger ones lately that we are becoming numb to the "lesser"6s.

Well, that all depends. I was in the Nisqually earthquake in 2001 which was 6.8, and it resulted in zero deaths and only light to moderate damage. Compare that to the Northridge earthquake of 1994, which was only 6.7, but resulted in 72 deaths and did catastophic damage. It's all based on the topography around where it hits, its depth, and how close to a major population center it is.

The thing to remember about the numerical rating of earthquakes is that the number only rates the amount of energy in the quake. A 4.0 quake very near to the surface and directly under a city will do more damage than a 7.0 quake at great depth and far away from a population center. Other factors are the makeup of the ground where the quake occurs. If the ground is solid rock it will transmit the energy to structures much more efficiently than if the quake happened in soft soil areas. There are many factors to consider but you just have to keep in mind that the size of the quake as in a 7.5 or so is less important than where it hits in most cases.

Yeah your right.
