WORLDWIDE EARTHQUAKE REPORT OCTOBER 21
Two M5+ earthquakes occurred in the past 24 hours. The strongest was a M5 2 in Tonga. The earthquake occurred at an intermediate depth of 150.6 km beneath the epicenter late at night on Friday, October 21st, 2022, at 10:18 pm local time. Because of the depth, the quake might have been felt as
very weak in Bangai (pop. 1,700) located 69 km from the epicenter.

Possibly the 6.7 magnitude earthquake in Panama (Cocos plate) caused the increase of seismic activity in the Caribbean plate. In the last 24 hours the following earthquakes were recorded in the Caribbean region:
●M 2.5 - Mona Passage (Puerto Rico)
●M3.5 - 60 km SE of Punta Cana, Dominican Republic
●M 3.3 - 37 km N of San Antonio, Puerto Rico
●M 3.0 - 2 km SW of Palmarejo, Puerto Rico.
●M 2.5 - 5 km E of Mayagüez, Puerto Rico
●M 3.0 - 70 km N of Brenas, Puerto Rico
●M 2.6 - 4 km S of Magas Arriba, Puerto Rico.
Some experts point out that the energy from the M7.6 earthquake in Mexico is still migrating towards the Nazca plate. The Panama earthquake and recent activity in the Caribbean and South America seem to indicate this. In the past 24 hours, minor to moderate activity was also recorded in South America.
● M 4.2 - 84 km E of Arica, Chile
● M 4.7 - 41 km W of Ovalle, Chile
● M 4.7 - 84 km W of Abra Pampa, Argentina
● M 4.6 - near the coast of northern Peru
● M 4.4 - 52 km WSW of La Quiaca, Argentina
An earthquake of magnitude 4.4 occurred around noon on Friday, October 21st, 2022, at 1:45 pm local time near Al Hoceima, Al-Hoceima, Tanger-Tetouan-Al Hoceima, Morocco.
