A magnitude 3.3 earthquake occurred at a depth of 1.7 km, 57 km northeast of Kelly, Wyoming. [1] This event formed part of the cluster of minor earthquakes today that affected multiple countries without causing damage or injuries. The precise location 57 km northeast of Kelly places the epicenter in a remote area of Wyoming according to the recorded data. [1] Depth measurements indicate the quake originated at 1.7 km, which aligns with typical shallow seismic activity patterns noted in the report. [1]
Colombia Quake in Chocó
A magnitude 3.7 earthquake struck at a depth of 38 km near Medio San Juan in Colombia's Chocó department at approximately 5:15 p.m. local time, 12 km from Sipí. [2] The Servicio Geológico Colombiano reported the movement telúrico with its epicenter in the municipality of Medio San Juan (Andagoya). [2] This quake registered a magnitude of 3.7 and occurred on the afternoon of September 6, 2026. [2] Colombian authorities encouraged residents to report felt tremors via an official online form and provided guidance on earthquake preparedness and response. [2]
Mendoza, Argentina Tremor
A magnitude 3.4 earthquake was recorded at a depth of 102 km near Uspallata in Mendoza province, Argentina, at 8:48 a.m. local time, with its epicenter 43 km north of Uspallata and 93 km northwest of Mendoza city. [4] The Instituto Nacional de Prevención Sísmica confirmed the event occurred at 8:48:05 local time with no damages or injuries reported. [4] The epicenter coordinates positioned it 120 km southwest of San Juan city as well. [4] Due to the intermediate depth of 102 km, surface perception remained limited and mainly noted in high mountain zones and elevated structures. [4]
Alaska Seismic Events
Two additional minor quakes of magnitude 3.2 and 2.9 struck near Dutch Harbor, Alaska, at depths of 10.8 km and 8.4 km respectively. [3][5] The magnitude 3.2 event took place 8 km west of Dutch Harbor at 10.8 km depth. [3] The magnitude 2.9 event occurred 5 km west of Dutch Harbor at 8.4 km depth. [5] These formed part of the day's minor earthquakes today recorded by monitoring agencies in the United States. [3][5]
Safety Guidance from Colombian Authorities
Colombian authorities encouraged residents to report felt tremors via an official online form and provided guidance on earthquake preparedness and response. [2] The Unidad Nacional para la Gestión del Riesgo de Desastres recommends families prepare an emergency plan that includes an evacuation route, identification of safe sites, and an emergency kit containing water, flashlight, radio, non-perishable food, and identification documents. [2] During a tremor, guidance advises maintaining calm and protecting oneself in structurally secure zones such as under a desk or near a column while avoiding doors, windows, or loose objects. [2] After the event, recommendations include acting with caution, not using elevators, avoiding running or pushing, evaluating structural damage before re-entering buildings, shutting off basic utilities if safe, and staying informed through official channels. [2] The Servicio Geológico Colombiano also highlighted the Sismo Sentido form at sismosentido.sgc.gov.co for reporting perceptions. [2]
What to watch next: Authorities continue to monitor for any follow-up activity in the affected regions while residents in Colombia can use the Sismo Sentido form to contribute reports.
