| Scientists Finally Solve the Mystery of “Clockwork” Earthquakes |
|
|
2026-05-21 20:32:49 +00:00
 Scientists discovered hidden underwater “brakes” that may keep some earthquakes from becoming catastrophic. For more than 30 years, a fault line deep beneath the eastern Pacific Ocean has been producing remarkably consistent earthquakes. Located about 1,000 miles off Ecuador’s coast, the underwater fault generates magnitude 6 quakes every five to six years, striking in nearly [...]
