A M8.8 earthquake just ruptured the subduction zone offshore Russia’s Kamchatka peninsula. This is one of the world’s truly huge earthquakes, and a triggered tsunami is currently traveling across the Pacific ocean.

This same fault ruptured on July 20th in a M7.4, and last August in a M7.1. We wrote about those earthquakes, wondering: should they be considered warnings of elevated risk? We didn't have a good answer then, and we still don't.
