Researchers discovered a massive 1,180-ton boulder inland in Tonga, evidence of a 6,900-year-old tsunami likely caused by a submarine landslide or volcanic activity, revealing that ancient waves may have been more than twice as high as recent events, informing modern hazard assessments.
A new study suggests that aftershocks can occur decades or even centuries after the original earthquake. Researchers analyzed historical earthquakes in North America and found that nearly a third of modern quakes in the Missouri-Kentucky area were likely aftershocks from an event in 1811-12, while about 16% of recent quakes in the Charleston region are probably aftershocks from a quake in 1886. Recognizing aftershocks is crucial for assessing a region's disaster risk.
