I continued looking around for some more information on the link between solar effects and earthqaukes and I found a youtube video.
It is an interview with Piers Corbyn. The interviewer covers some other aspects of the Japan earthquake for a few minutes before interviewing Piers.
Piers Corbyn is an astrophysisist with an incredible record of weather predictions based on solar and lunar effects. When it comes to the sun, the moon, and our weather – he is one of the world’s best. The video is definitely worth a listen.
And over at Climate Realists there is an article describing what might have caused thee other volcanoes to erupt about the same time as the Japan earthquake.
