UPDATES: Destructive tsunami in Russia’s Kamchatka Peninsula, with first tsunami waves in Japan arriving presently. This was a magnitude 8.8 “megathrust” quake. The dense Pacific plate is crunching against the Othotsk plate at a rate of 77 millimeters (3 inches) per year. The dense Pacific plate subducts, or sinks beneath the Othotsk plate, along the Kuril-Kamchatka Trench. That makes megathrust quakes. This is the biggest quake worldwide since the March 2011 Japan earthquake and tsunami disaste

A 9.0 megathrust earthquake along the Cascadia Subduction Zone would be one of the most destructive disasters in North American history. Scientists warn the 1,000 km fault from Vancouver Island to Northern California is capable of minutes of violent shaking, massive ground rupture, and a tsunami arriving within 15–30 minutes. This 15-second cinematic simulation shows how quickly the event could unfold — from the violent plate rupture offshore to the shaking in major cities like Seattle, Portland
