Scientists discover hidden “brakes” that stop massive earthquakes

A mysterious underwater fault near Ecuador has been producing nearly identical magnitude 6 earthquakes every five to six years, baffling scientists for decades. Researchers now believe the fault contains hidden “brake zones” where seawater and unusual rock structures work together to stop quakes from becoming even larger. The discovery came from ultra-detailed seafloor recordings that captured how the fault behaves before and after major earthquakes.
