Earthquake, another violent tremor right here… More…
The shallow depth of the earthquake, only 9 kilometers below the seabed, confirms its shallow nature and explains why it was clearly detected by seismic monitoring instruments.
The precedent of the great earthquake of 1700
Researchers note that the entire region is part of the Cascadia subduction zone, a gigantic geological structure nearly a thousand kilometers long, considered one of the most dangerous in the world.
Historical and geological research has shown that this fault was responsible for one of the most powerful earthquakes ever recorded in the region. In January 1700, the Cascadia subduction zone generated a megathrust earthquake estimated at between magnitudes 8.7 and 9.2, accompanied by a tsunami that crossed the entire Pacific Ocean and reached the coast of Japan.
