In the time between mega-earthquakes, smaller earthquakes continuously occur between oceanic and continental plates (background earthquakes). Where a lot of energy is released through these earthquakes, we observe coastal mountains that rise faster. In contrast, slow-uplifting coastal areas coincide with fewer background earthquakes.

Using a method to better locate the source of weak tremors from regions with complex geological features, researchers found that many tremors originate from the shear zone, an area of high fluid pressure, in the Nankai Trough, which is schematically shown here with structures of tectonic plates and fault lines.

Making sense of commotion under the ocean to locate tremors near...

Closeup of the stomach area of a fossil ichthyosaur, Guizhouichthyosaurus, showing part of the body of another large marine reptile. The ichthyosaur had swallowed its prey shortly before it died and was fossilized. This is the oldest known direct evidence of megapredation, or a large animal eating another large animal.
