The seismic event occurred at 12:53 Italian time, or 4:53 a.m. on the northwest coast of the United States. According to data collected by experts, the hypocenter was located approximately 9 kilometers below the ocean floor.
Along these geological structures, movements occur through lateral sliding of rock masses, frequently triggering shallow earthquakes like the one recorded in recent hours.
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.
