A powerful earthquake shook fishing villages along Mexico's Gulf of California.
The US National Earthquake Information Centre said yesterday's 6.9-magnitude quake was centred 331 miles south east of the border city of Tijuana.
Civil protection officials in the two states on either side of the earthquake - Baja California and Sonora - said there were no reports of damage or injury.
The quake came minutes after two others calculated at magnitudes 5.8 and 5.0, according to the earthquake centre.
The quakes were all centred in the middle of the narrow slice of sea between the Baja peninsula and Mexico's mainland, which should help cut down on its chances of causing major damage, said Don Blakeman, an analyst at the centre.
