Analysis Debunks Claim of World's Deepest Earthquake in Japan
Originally Published 6 months ago — by Earth.com
A new analysis refutes the claim that the world's deepest earthquake occurred in Japan, showing that the deepest aftershocks linked to the 2015 Bonin Islands quake were only about 422 miles deep, within the upper mantle, and not in the lower mantle as previously thought. The study used advanced seismic techniques to identify only shallow aftershocks, suggesting that the mantle's 410-mile boundary acts as a barrier to deeper earthquakes, and emphasizing the importance of precise seismic data in understanding Earth's interior.
