A welcomed break for Japan. One good thing since the Honshu Earthquake


We are now at the 24 hour mark since an after shock of magnitude 6.0 or higher has struck. While this may seem as a very thin silver lining, the fact that Japan is now shaking hourly with only 5.x magnitude and lower aftershocks is significant. This is a case where you could honestly say, “well, you would have to be there to understand”.

Here are descriptions to give you a feel for the difference between the magnitude 5 aftershocks that Japan is feeling today and the magnitude 6 they were feeling yesterday.

5.0–5.9 Moderate Can cause major damage to poorly constructed buildings over small regions. At most slight damage to well-designed buildings. 800 per year

6.0–6.9 Strong Can be destructive in areas up to about 160 kilometers (100 mi) across in populated areas. 120 per year

In terms of dynamite stacked up and exploded all at once, a 5 magnitude earthquake is equivalent to about 500 tons of TNT. A magnitude 6 earthquake is equivalent to 15 thousand tons of TNT exploded at once.

Depending on how far away you are from Honshu, this may mean the difference between being able to sleep for the first time since the earthquake, or spending another sleepless night.

Oh, and just in case you still haven’t gotten the severity of the initial 8.9 Magnitude earthquake at Honshu….. have you ever heard of Krakatoa? The 1883 eruption of Krakatoa is considered to be the loudest sound ever heard on the planet. That was an 8.7 magnitude earthquake. The Honshu earthquake was the equivalent of just over of 400 million tons of TNT blown up at once. “Millions of tons” is know as “mega-tons” and is the term used to measure modern atomic weapons. Each of the 6 magnitude earthquakes they were feeling yesterday were equivalent to the atomic bomb dropped on Japan in WWII. The 400 megaton earthquake is stronger than any nuclear weapon in any arsenal anywhere in the world. In fact it is the equivalent of the United States dropping over 25 of its largest nuclear bombs on the Honshu at once.
