- A recent earthquake near Russia’s Kamchatka Peninsula suggests magnitude 9 “megathrust” quakes could occur more frequently than previously thought.
- Researchers found evidence of an “overshoot” phenomenon, where earthquake slip exceeded the equilibrium stress level, releasing strain from prior, unreleased seismic activity.
- This phenomenon poses a potential risk for other areas, including the Nankai Trough, Chishima Trench, and Sagami Trough.
