The Cause

Santiago, Chile received an abnormal amount of rain over the last week causing dangerous conditions such as landslides and flooding. Mayor Catalina San Martin of the Las Condes district stated that the region received 5.7 inches (14.4 cm) of rain in recent days which is about nine times the average October rainfall. Some researchers argue that the escalation in rainfall may be in part due to the strengthening of a powerful El Niño which can bring wetter conditions to the Southern Hemisphere. 

Flooding and Landslides

Running through Santiago is the Mapocho River and the extreme raining conditions caused the river to overflow. Reports of overflows in local canals and drainage systems are also believed to worsen the condition. Heavy rain fell on the mountains east of Santiago and soaked the ground so thoroughly that a ravine, which is a natural channel that normally carries small amounts of water downhill, suddenly turned into a powerful stream. The rushing water picked up mud, rocks, and debris, and when a nearby canal overflowed, even more water poured into the area, creating a fast-moving flood that swept through streets and neighborhoods.

Evacuation orders were issued and multiple reports and videos show that the landslides and floods have swept away numerous vehicles in the region while also damaging private and public infrastructure. One video even shows the moment a bus is swept down a surging river of mud with passengers clinging to the roof.  Chile's disaster-response agency put 10 other districts on high alert for more landslides and schools were closed on Friday (10/09/2026). The U.S. embassy in Chile put out this warning:

Recovery Operations

No deaths have been reported so far, although six people were injured, including a 1-year-old child who suffered broken bones. Chilean firefighters rescued or evacuated more than 1,000 people, while the Chilean Army deployed specialist vehicles, infantry soldiers, and emergency response teams to assist with rescue and clean-up efforts.

The exact number of vehicles swept away remains unknown, and reports have not provided complete figures for damage to homes, roads, and businesses. It is also unclear whether all evacuations have been completed or how long affected streets will remain closed, as officials were still assessing the situation.
