A second large flash flood of 2026 has struck Nepal’s Gorkha district, just west of the area affected by the August Trishuli River flood. This second flood occurred in the early hours of Sunday, 11 October 2026, on the Budhi Gandaki River. While not as large as the August Trishuli flood, the Budhi Gandaki still produced significant damages in the area.

On 9 October 2026 at 12:56 PM local time (17:56 UTC), a moment magnitude (Mw) 7.7 earthquake struck the Azuero Peninsula in southern Panama. The mainshock was followed by a vigorous sequence of aftershocks, i ncluding an Mw 6.6 earthquake approximately 2.5 hours later , a Mw6.1 and Mw6.0 in the following days. The earthquakes cause widespread slope failures across the region.
On the morning of August 26, 2026 (Nepal local time), a catastrophic debris flood swept through central Nepal along the Lhende Khola–Bhote Koshi/ Trishuli river system, causing significant damage across three districts (Rasuwa, Nuwakot and Dhading). The flood moved exceptionally fast (up to 75 km/hr), was sediment-laden, and extreme in scale. The CLaSH rapid response team has collected information and performed intial analysis on the event.

A M7.4 earthquake occurred near the west coast of Colombia on 10 August 2026 destroying thousands of homes and causing significant damage. Imagery is limited in the region but the CLaSH rapid response team mapped nearly 600 landslides, however, majority of these failures appear to be small and in the densely forested region west of Cartago.
Two sequential earthquakes, M7.2 and M7.5, struck northern Venezuela on 24 June 2026 and produced widespread damage and thousands of casualties in the area. USGS and GEER led responses to this event. The CLaSH rapid response team has been coordinating with both agencies and remains on standby to provide support as the situation develops.

On 8 June 2026, a M7.8 earthquake struck offshore southern Mindanao, Philippines, causing widespread damage including building failures, significant landsliding and coastal change. The CLaSH rapid response team mapped nearly 7,000 landslides in the region. More information on the virtual response can be found here and plans to further these initial findings. CLaSH is working closely with Filipino collaborators and considering a field deployment.
