Further International Seismic Reports

Three tremors were recorded this Friday in Colombia. [4] The last one reached magnitude 4.5 and occurred at 41 kilometers depth in Istmina. [4] A new seismic movement was reported on Friday 11 of September in Colombia, with the event in the department of Chocó reaching a magnitude of 4.5 according to the updated bulletin from the Colombian Geological Service. [4] The tremor occurred at 11:42 in the morning local time with a depth of 41 kilometers, and the epicenter was located in the jurisdiction of Istmina, Chocó. [4] Preliminary reports indicate the movement was felt in Cali, Pereira and other regions, prompting evacuations in some places due to the perception of the shaking. [4] No injuries or associated damage have been reported so far. [4] Two additional earthquakes were reported during the morning, one of magnitude 3.6 at a depth less than 30 kilometers in Pacific Ocean waters with epicenter approximately 104 kilometers from Mosquera, Nariño, and another of magnitude 2.6 at superficial depth near Frontino in the department of Antioquia.

What to watch next

Reports note that a replica of 6.9 occurred hours after an earlier 7.7 magnitude event on August 15 along the coast of the island of Flores in eastern Indonesia, though that replica caused no visible damage. [3] The Colombian Geological Service continues monitoring seismic activity and reminds citizens they can report felt movements through its Sismos Sentidos platform. [4]
