Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

[July 20, 2012] Mass die-offs resulting from human impact and the planetary response to the anthropogenic assault could occur by early 2016.  SYMBOLIC COUNTDOWN: 1,335 Days Left to the ‘Worst Day’ in Human History…

Izu-hanto Japan hit by another quake

Posted by feww on December 18, 2009

Shallow earthquake measuring 5.3Mw strikes 75 km (45 miles) E of Shizuoka, Honshu, Japan

The quake was the latest event in a swarm of earthquake that have struck the area since Thursday.

The latest event was located at 35.0N, 139.1E, and occurred at 08:45 JST on 18 Dec 2009, and at a “very shallow” depth, JMA said.

FEWW Comment: More intense seismic activity may occur in the region. Other geophysical events including seismic, volcanic activity and submarine eruptions may be occurring. The geophysical events in the region could herald a change to the map of Japan.

Large Swarm of Quakes Strike Near Honshu, Japan

Posted by feww on December 17, 2009

Earthquake Measuring M5.3 Strikes Eastern Honshu, Japan

The earthquake was preceded by a large swarm of smaller quakes which began striking SSW of Tokyo, near the south coast of Honshu, early Thursday Japan time.

JMA has recorded about 5 dozen quakes measuring 2.0 to 5.3 Mw in the Izu-Hanto region. It appears that submarine volcanic eruptions may be occurring.

The northern Izu Island arc is a tectonically active region, where several destructive interplate [and intraplate] earthquakes, severe earthquake swarms and volcanic eruptions have previously occurred.
