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

Larger Shocks May Occur

Cluster of at least 9 shocks strike offshore Oregon

Earthquake measuring about 5.4Mw struck the offshore Oregon about 500km west of Eugene on Friday, May 07, 2010 at 17:46:15UTC.

Epicenter of the earthquake was located near 44.396°N, 129.437°W and occurred at a depth of  10 km (6.2 miles). The initial shock was followed by at least 8 other events [aftershocks] measuring a mean magnitude of about 4.4Mw.

Center of the cluster was about 1,000km (600 miles) south of  a magnitude 8.1 shock that occurred on the Queen Charlotte Fault off Queen Charlotte Island on August 22, 1949. That event was Canada’s largest earthquake since 1700.
