Earthquakes Today Strike Peru and Colombia, Largest 5.1
Earthquakes today struck Peru and Colombia on August 26, 2026, with the largest registering magnitude 5.1 in Colombia's Santander region at a depth of 149 km, following several smaller tremors overnight in both countries. [2]
Overview of Seismic Activity on August 26
Multiple earthquakes today occurred across Peru and Colombia within a 24-hour period, with the largest magnitude recorded at 5.1. [2] A separate USGS-reported magnitude 4.9 earthquake occurred 4 km east of Jordán, Colombia at 159.9 km depth. [4] A minor magnitude 2.5 quake struck 19 km west of Anchorage, Alaska at 15.4 km depth. [3] Peru recorded three earthquakes on August 26 while Colombia experienced seven small earthquakes overnight with two reaching magnitude 3.1 in Los Santos, Santander, followed by the magnitude 5.1 event at 11:45 a.m. local time near Los Santos at 149 km depth. [2] [5]
Earthquakes Reported in Peru
Peru recorded three earthquakes on August 26: magnitude 4.0 in Tumbes at 1:26 a.m. at 97 km depth, magnitude 3.6 near Chupaca in Junín at 2:40 a.m. at 10 km depth, and magnitude 3.5 near Huánuco at 5:02 a.m. at 15 km depth. [5] The first of the three movements occurred at 1:26:04 a.m. with epicenter 61 km east of Zarumilla in Tumbes at depth of 97 km. [1] Hours before 5:02 a.m., the IGP registered a movement in Junín with magnitude 3.6 at depth of 10 km and epicenter 17 km south of Chupaca. [5] The most recent occurred at 5:02:31 a.m. with epicenter 20 km west of Huánuco at depth of 15 km and intensity II-III in Huánuco. [5] The reports provided by the IGP for these three events do not constitute evidence of a relationship between the movements. [1]

Colombia’s Overnight Tremors and Mainshock
Colombia experienced seven small earthquakes overnight with two reaching magnitude 3.1 in Los Santos, Santander, followed by a magnitude 5.1 event at 11:45 a.m. local time near Los Santos at 149 km depth. [2] Between 1:08 and 6:00 a.m. seven sismos were reported in Chocó, Bolívar, Santander and Cesar, with the two of greater magnitude during that period reaching 3.1 and located in Los Santos, Santander, at depths near 150 km. [2] The magnitude 5.1 recorded at 11:45 is therefore significantly greater than the earthquakes reported during the early morning. [2] The Servicio Geológico Colombiano issued a bulletin placing the earthquake at 11:45 local time and establishing a depth of 149 km, noting it was a preliminary bulletin. [2]
Additional Global Activity and Tectonic Context
A minor magnitude 2.5 quake struck 19 km west of Anchorage, Alaska at 15.4 km depth. [3] Both Peru and Colombia lie in seismically active zones; Peru along the Pacific Ring of Fire due to Nazca and South American plate convergence. [1] Forty to 50 percent of Colombia's daily seismic activity concentrates in the Bucaramanga seismic nest, with the Servicio Geológico Colombiano network detecting around 80 quakes per day. [2] Colombia is a country with elevated seismic activity due to its complex tectonic context. [2]
Government Response and Damage Assessment
No official reports of casualties or material damage from the Colombian magnitude 5.1 event as authorities continued to assess impacts. [2] The Presidency of Colombia reacted minutes after the movement and confirmed it maintains permanent communication with authorities and risk management organisms to verify possible effects. [2] Until the last official information available, no consolidated balance of victims or material damage had been released. [2] The Presidency asked citizens to remain calm and stay attentive to information issued by official organisms. [2]
Safety Recommendations and Preparedness
Earthquakes cannot be predicted and multiple daily tremors do not necessarily signal a larger event. [1] Before a teluric movement, maintain calm and head to a previously identified safe zone. [1] Indeci recommends having a family emergency plan, identifying safe zones inside and outside the home, participating in drills and periodically reviewing the state of buildings. [1] It is also important to have an emergency backpack ready with basic elements to face the first hours after a possible disaster, including water, non-perishable foods, flashlight, battery radio, first aid kit, medicines, bandages and band-aids, alcohol or disinfectant, blankets, hygiene articles and specific products for babies, older adults or people with special needs. [1] After a strong movement, avoid approaching damaged structures and remain attentive only to information disseminated by official authorities. [1]
What to watch next: Authorities in Colombia continue verifying possible effects from the magnitude 5.1 event while the Servicio Geológico Colombiano monitors activity, and the IGP in Peru continues monitoring national seismic activity with updates available through its Centro Sismológico Nacional.
