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

At Least 3 Powerful Earthquakes Strike Mindanao, Philippines

The Largest Quake in the Cluster Measured up  to 7.9M. The quakes struck at a depth of about 600km and did not cause a destructive tsunami.

About a dozen strong aftershocks, the largest of which  measured up to 6.0Mw  followed the mainshock.

    Powerful Earthquake Strikes Celebes Sea, S of Philippines

    Posted by feww on October 8, 2009

    Earthquake Measuring up to 7.1Mw Strikes Celebes Sea

    Powerful earthquake measuring up to 7.1 Mw Struck Celebes Sea, SE of Jolo, Sulu Archipelago, Philippines, on Wednesday, October 07, 2009 at 21:41 UTC at a depth of about 580km.

    The event followed another powerful earthquake that struck Moro Gulf (Mindanao, Philippines), on Sunday, October 04, 2009.

    On September 18, 2009, after a 5.5 Mw quakes struck south of Mindanao, FEWW forecast additional, more powerful,  earthquakes for the region.

    Latest Earthquakes Magnitude 5.5 +

    Posted by feww on September 19, 2009

    Latest Earthquakes Measuring Magnitude 5.5 or Larger since September 18, 2009

    The following significant earthquakes occurred within a 12-hour period.

    The Bali Earthquake detailed below was reported as a Magnitude  6.0  shock by the  European-Mediterranean Seismological Center. 

    GFZ Potsdam – Earthquake Bulletin
    Region: South of Bali, Indonesia
    Time: 2009-09-18 at 23:06:59.5 UTC
    Magnitude: 5.9
    Epicenter: 115.42°E 9.47°S
    Depth: 77 km
    Status: automatic

    The quake was described as “very strong” by a number of people who sopke to the media. People were reportedly jumping from building and running away from their homes in panic after the quake struck. Up to a dozen people have been injured, some hurt jumping from buildings while others were hit by falling debris, according to news reports quoting officials.  No tsunami warning was issued.

    An earthquake on the main Indonesian island of Java left more than 50 dead on September 2, 2009.

    The 9.3 Mw Sumatra-Andaman earthquake which caused the 2004 Indian Ocean tsunami that killed an estimated quarter of million people in 11 countries, was the second largest earthquake recorded on a seismograph. The earthquake was also characterized by the longest ever duration of faulting lasting about 10 minutes, which made the entire planet to vibrate about 1 cm triggering earthquakes as far north as in Alaska.

    FEWW Comments: More Mega-quakes should be expected in this region and other areas in the coming months. FEWW will post a separate [disturbing] forecast later.
