Which consequence results when deep-sea methane clathrates destabilize during a submarine earthquake?

💡 Explanation

Earthquakes trigger the release of seafloor methane hydrates via pressure reduction creating massive underwater landslides because gas hydrate instability causes substantial increases in sediment pore-water pressures, therefore tsunamis are amplified rather than just seismic shaking.
