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

Powerful Quake Strikes Vladivostok Region

Earthquake measuring up to 7.0Mw strikes near China-Russia-North Korea border area

A powerful quake measuring up to magnitude 7.0 Struck  near China-Russia-North Korea border region (42.7ºN131.1ºE) on Thursday, February 18, 2010 at 01:13UTC, at a depth of about 590 km.

The quake was felt as far east as the eastern coast of Honshu, east of Tokyo, Japan’s Meteorological Agency (JMA) reported.

The event was the 12th earthquake measuring between 7.0 and 7.8 to strike the region since 1900, and the fourth such event since 1990, according to USGS earthquake data.

The quake epicenter appears to be located in sparsely populated Chinese territory. It too deep to cause any tsunami, or major damage to the nearest major cities of Vladivostok, Russia,  and Chongjin, North Korea. As of posting, there was no report of injuries as a result of this event.
