A magnitude 6.2 earthquake struck near the southern part of Mexico's Baja Peninsula Tuesday, the U.S. Geological Survey reports.
State civil defense director Carlos Rincon said there were no immediate reports of damages or injuries in La Paz, a tranquil fishing and resort city.
"We are calling on the public to remain calm in case there are aftershocks," Rincon said.
The offshore earthquake was centered about 47 miles north of La Paz, Mexico. The USGS said the quake occurred at about 4:45 p.m. local time.
About twenty minutes later, a 4.6-magnitude aftershock occurred about 24 miles north of La Paz. That quake was also centered in the Gulf of California.
