5.4 quake hits Baja California
Story Highlights
# Quake is centered about 100 miles east of Tijuana; no injuries, damage reported
# At least 15 aftershocks follow, some with preliminary magnitudes of 3.0 or greater
# 400,000 people without electricity and 1.2 million without cellular telephone service
# About 80,000 workers evacuated from factories to check buildings' structural integrity
LOS ANGELES, California (AP) -- A moderate earthquake rocked Baja California in Mexico, shutting down factories near the U.S. border and leaving about 400,000 people without power, authorities said Saturday. No major damage or injuries were immediately reported. The quake that struck around 11:15 p.m. Friday had a preliminary magnitude of 5.4, said Jessica Sigala, a geophysicist with the U.S. Geological Survey in Golden, Colorado. It was centered 16 miles southeast of the border town of Mexicali and about 100 miles east of Tijuana. "It has been felt pretty widely in Southern California, southwestern Arizona and probably northern Mexico," Sigala said.
It was followed by at least 15 aftershocks, including four with preliminary magnitudes of 3.8, 3.6, 3.5 and 3.0. The quake left about 400,000 people without electricity and 1.2 million without cellular telephone service, said Fire Capt. Rene Rosado, director of civil defense in Mexicali. About 80,000 workers were evacuated or were unable to enter factories for Sony Corp., Honeywell International Inc. and other major corporations that typically run 24 hours a day until the buildings could be checked for damage, he said. Two bridges showed 2- to 3-inch cracks and were closed until engineers could assess their safety, he said. The Baja peninsula is a geologically active region. In 2006, a magnitude 5.4 temblor struck the Mexicali area, but there were no injuries or damage

Earthquake Strikes Mexico Near U.S. Border
TIJUANA, Mexico — A moderate earthquake struck northwestern Mexico near the U.S. border Monday, prompting authorities to evacuate schools and resulting in at least one minor gas leak.
No major damage or injuries were reported from the temblor, which an expert said was likely an aftershock from a magnitude-5.4 quake three days ago.
The magnitude-4.9 quake hit around 10:30 a.m. local time (1:30 p.m. EST). It was centered about 20 miles southeast of the border city of Mexicali, and 24 miles southeast of the U.S. border city of Calexico, California, according to the U.S. Geological Survey. The magnitude was revised downward from an initial calculation of 5.1.
In Mexicali, an industrial border city of about 750,000, the quake caused the wall of a school to fall and started a gas leak in a second school, prompting authorities to evacuate all of the city's learning centers, said Alfredo Escobedo, civil protection director for the Mexican state of Baja California, which includes Mexicali. Escobedo said no injuries or other damages had been reported.
The latest earthquake came three days after the Mexicali area was rocked by a magnitude-5.4 quake that shut down factories and left 400,000 people without power. That quake was felt in parts of California and Arizona, the USGS said.
The latest temblor was likely an aftershock, said Julie Martinez, a geophysicist at the National Earthquake Information Center in Golden, Colo.
A series of smaller quakes, ranging from magnitudes 2.5 to 2.9, preceded Monday's temblor and there were at least five aftershocks, including one registering a magnitude-3.6, the USGS said.
In 2000, the northern Baja California region near Mexicali was rattled by a cluster of quakes, but they did not cause any apparent damage.

Magnitude-6.4 Earthquake Hits Southern Mexico, Effects Felt Hundreds of Miles Away
A magnitude-6.4 earthquake shook southern Mexico on Tuesday, but there were no immediate reports of major damage.
The quake gently swayed buildings in Mexico City and rocked parts of Mexico's southern Pacific and Gulf coasts. In the southern city of Tuxtla Gutierrez, many people fled into the streets and then lingered outside their homes, fearing aftershocks.
"It was horrible," said Cecilia Gomez, standing with her family outside her home. "It really scared me."
Daniel Roque, of southern Chiapas state's civil protection agency, said some residents reported panic attacks, but no damage was registered.
The U.S. Geological Survey said the quake struck at 6:50 a.m. (7:50 a.m. EST) and was centered 70 miles southwest of Tuxtla Gutierrez, near the border between Oaxaca and Chiapas states.

Earthquake Shakes Guantanamo Bay, No Damage to U.S. Base
The magnitude-4.4 tremor occurred at 9:09 a.m. EST and was centered about 35 miles southeast of the base in the southeast corner of Cuba, the Navy said.
Base spokesman Bruce Lloyd said the two-story headquarters building, Bulkeley Hall, shook for several seconds when the earthquake struck.
"We thought a truck had hit the building, a good size truck," Lloyd told The Associated Press.
There was no significant damage to any buildings on the base, according to Cmdr. Sylvester Moore, the executive officer of the Navy base.
Earthquakes are not unusual in the Caribbean, though this was the first felt at Guantanamo this year, the Navy said.

Quake swarm near the border has residents on edge
Residents of the Imperial Valley are living on shaky ground these days.
Since Friday, cities such as Calexico and El Centro, as well as Mexicali across the border, have been rocked by hundreds of earthquakes, from tiny to teeth-rattling -- three have registered a magnitude of 5.0 or more.
The onslaught of temblors is known as a swarm, in which quakes of varying sizes can strike every few minutes, said Kate Hutton, a staff seismologist at the California Institute of Technology. The Imperial Valley and Baja are prone to the swarms, she said; they can last a few days to a week.
Though the quakes aren't breaking any geologic records, they've caused several sleepless nights for Calexico resident Barbara Lopez.
"It's been scary," said Lopez, a 27-year-old apartment leasing agent, of what she describes as nonstop quakes. "You're like constantly thinking: 'Is the big one going to hit? Are we prepared?' Of course we're not."
Lopez has already stashed her $300 mirror between the couch and the wall, along with her computer and breakable family photos. She and co-workers at Desert Properties in El Centro spent part of Tuesday running through earthquake drills in the office.
Firefighters in the region say that although the quakes are jangling people's nerves, they have not caused any structural damage or injuries.
"In the grand scheme of California earthquakes, they've been pretty mild," said Richard Burns, a battalion chief in the El Centro Fire Department. The Calexico Fire Department sent a mutual assistance team to Mexicali recently to check for damage to the city's downtown but didn't find anything serious, said Calexico firefighter Joe Guerra.
The region sits atop a geothermal area, where past volcanic activity has kept underground rocks hot, Hutton said. That heats the groundwater, which could lubricate local fault lines.
El Centro coffee shop cashier Gloria Estrada has been running for cover in doorways at home and work over the last few days. Although her radio crashed to the floor on a recent night, in her opinion the locals "are used to it."
Lopez describes the tremors, which scare her young daughters, "like a big rumble, then all of a sudden the house starts moving."
"Right when you're like going back to sleep, it starts shaking."
Fortunately she has a built-in earthquake alarm: Her two basset hounds, Tiny and Tubby, start barking each time the earth's about to move.

Magnitude 5.0 Quake Shakes California-Mexico Border
An earthquake swarm rattling for nearly two weeks under the California-Mexico border region unleashed another nerve-jangling jolt and numerous aftershocks Tuesday.
The day's big quake struck at 2:41 p.m., centered in Mexico about 20 miles southeast of Calexico, a U.S. border city of more than 37,000 residents. There were no reports of any injuries or damage in Imperial County on the U.S. side, authorities said.
The U.S. Geological Survey reported the quake was magnitude 5.0 but USGS geophysicist Rafael Abreu said it occurred in the area of a seismic network operated by Mexico which put it at 5.3. Such differing magnitude reports and later adjustments of magnitude are common.
"It started off with a little jolt, then a rumble," said Sgt. Mike Misteriel of the Imperial County Sheriff's Department. The aftershocks producing a rolling sensation, he said.
It was the fourth moderate quake since the swarm began on Feb. 8, raising anxiety in southeastern California and across the border in the sprawling Baja California city of Mexicali. Some Calexico residents who are used to the region's frequent quakes said they're rattled by the current swarm.
