Worldwide – Earthquake Activity is Way Up

A global surge of great earthquakes from 2004-2014 and implications for Cascadia

“The last ten years have been a remarkable time for great earthquakes. Since December 2004 there have been no less than 18 quakes of Mw8.0 or greater – a rate of more than twice that seen from 1900 to mid-2004.”

. . .  High on the list of areas ripe for a great quake is Cascadia, the Pacific Northwest, where the risk for great quakes had long been under appreciated. Evidence began surfacing about 20 years ago that there had been a great quake in the region in the year 1700. Since then the view of the great quake risk in Cascadia has shifted dramatically.

Arizona Area: Methane Hotspot

Four Corners Region of The United States Has Huge Methane Concentration in Its Atmosphere- Satellite Image shows

“Satellite data has spotted a large cluster of methane gas that covers the sky over a portion of the southwestern United States. The finding shows that the EPA or Environmental Protection Agency is dramatically failing to appreciate the severity of methane leaks into the atmosphere. Residents of the affected area are not affected by methane levels, however, this is one of the factors creating global warming. The leaks take place when methane is pumped into coal mines. Methane levels are starting to worry scientists. . . . “
