Landslides from the 7 September 2021 M=7.1 Guerrero earthquake in Mexico
In the evening of 7 September 2021 (local time) a M=7.1 earthquake struck close to the city of Acapulco in Mexico. This event was shallow, leading to potentially high levels of damage in the worst affected areas. Wikipedia is calling this the 2021 Guerrero earthquake, but time will tell as to whether this is adopted as the formal name for the event.
At least three people were killed and 20 more were injured, a comparatively light toll for an event of this magnitude. Interestingly, one of the major impacts appears to have been landslides, although fortunately there are no known fatalities from these events.
Some images are emerging of landslides triggered by this event. The best set I have found so far is in the Daily Sabah, which has a gallery of images of the impacts of the earthquake, several of which show landslides:-
Given the topography and the scale of the earthquake, it seems likely that larger landslides will have occurred in the more remote mountainous areas of the epicentral zone. As yet I have not seen any images of such events, but it is likely that reconnaissance and fact-finding visits will be organised in the coming days. I would welcome any information that loyal readers can provide.
