Deep Earthquakes Suggest Well-Hydrated Mariana Subduction Zone

by Morgan Rehnberg 10 August 20222 March 2023

Earthquakes as deep as 50 kilometers below the seafloor were detected by 12 ocean bottom seismometers placed around the Challenger Deep.

Data from the J-OFURO3 satellite product showing monthly sea surface temperature variations across the global ocean. The red colors indicate sea surface temperature swings from month to month that are typically larger than 1.5°C, while dark blues and purples indicate variations that are typically smaller than 0.5°C.
