A preliminary 4.7 magnitude earthquake shook Baja California on Tuesday, with its effects felt by some residents in Southern California and Arizona. The United States Geological Survey (USGS) reported the quake occurred approximately 9 kilometers north of Delta, Mexico, at a depth of 15.6 kilometers.

The seismic event was initially registered as a 5.0 magnitude before being downgraded. Residents submitted reports to the USGS's “Did You Feel It” tracker indicating they felt the earthquake.

The USGS also stated there is a 66% probability of an aftershock measuring 3.0 magnitude or greater occurring within the next week.
