On Wednesday, the U.S. Geological Survey accidentally sent out an alert for a major earthquake in 2025.

The LA Times reports that the alert was originally sent by a Caltech staffer, who was trying to correct the location of an earthquake that struck Santa Barbara in 1925.

The alert said the quake would reach a 6.8 magnitude, and was set for June 25, 2025, the same day the 1925 earthquake struck.

The USGS released a statement online:
