In past postings I reported on what appears to be the average number of magnitude 6.5 or greater earthquakes that hit the Pacific Ring of Fire.
In going through the USGS’s Significant Earthquakes of the World, all the way back to 1999, it seems the Pacific Ring of Fire has about 50 per year.
The Pacific Ring of Fire involves not only the Pacific Plate, but the Nazca Plate, the Antarctic Plate, Cocos Plate, Juan de Fuca Plate, North American Plate, South American Plate, Scotia Plate, Filipino Plate, Eurasian Plate and Australian Plate, whew!
Well, from January 1 to February 12, 2012, there have already been seven “significant” earthquakes involving the plates of the Pacific Ring of Fire. In fact, so far, the only significant quakes for 2012 have been the seven around the Pacific Ring of Fire!
What about earthquakes in general? If you look at the USGS’s list of quakes from January 13 to February 4, 2012, the overwhelming majority are around the Pacific Ring of Fire. I counted at least 453 reported earthquakes around the Pacific Ring.
Most of the quakes are hitting Japan (with the most), California, Alaska, Mexico, Chile, countries on the Filipino Plate (like Indonesian islands getting hit almost as much as Japan), New Zealand and Vanuatu.
Vanuatu is a Southwestern Pacific Island north of New Zealand. Since the beginning of February it’s getting hit almost daily with quakes ranging from magnitude 4 to 5.
