A 7.2 magnitude earthquake struck northwest Mexico’s Baja California state Sunday, rattling Arizona and southern California, and leaving at least two dead and more than 100 injured in Mexico, authorities saidAt least one person was killed in a building collapse in Mexicali, Mexico, according to the assistant director of civil protection in Tijuana.

The other victim died when he ran from his residence into the street and was hit by a car, said Alfredo Escobedo, Baja state’s director of civil protection.

More than 140 people were treated at local hospitals, including five who were in critical condition, said Rigaberto Lasoya, medical coordinator for the state of Baja. Some were being treated outside because there’s no electricity and water at the main hospital, Lasoya said.

All injuries are concentrated in Mexicali, officials said.In California and Arizona, there were no immediate reports of injuries and only limited reports of damages.The quake struck at 3:40 p.m. (6:40 p.m. ET) about 110 miles east-southeast of Tijuana, Mexico, according to the U.S. Geological Survey.

Pictures from Mexicali, a major metropolitan area and the capital of Mexico’s Baja California state, showed sides ripped off buildings, telephone poles toppled, roads cracked and supermarket aisles strewn with food that had fallen off shelves.

The entire city has lost power, according to Alan Sandoval, Tijuana’s assistant director of civil protection

iReport.com: Water splashes out of San Diego, California,Residents across Southern California and Arizona reported serious ground shakes.”We have not felt a shake like that since about 1979,” Michelle Tapia told CNN from Brawley, California, approximately 23 miles north of the Mexican border.

iReport.com: Pots clang in San Diego, California, homeJoe Madison was shopping at a Wal-Mart in Palm Springs, California, when he felt the earthquake.”I felt the entire store move, and people went running for the exits,” he said.Madison said people gathered outside in the parking lot until the shaking stopped.”We felt it for about 30 seconds. It was rolling,” San Diego County sheriff’s Lt. Scott Ybarrondo told CNN. “Nothing fell off the walls here, but we have reports of pictures falling off walls elsewhere in the county.”

The quake was the largest in the Baja California area since 1992, the USGS reported.iReport.com: Damage in a bookstore in Palm Desert, CaliforniaThe 1992 quake, which struck in Landers, California, triggered an earthquake the next day in Nevada and another quake 11 days later in Southern California, according to USGS seismologist Lucy Jones. Both were 5.7 magnitude quakes.

Jones said Sunday’s quake also could trigger others in the coming days, though she said the relatively quiet hours after Sunday’s quake make other big quakes less likely.There have been three large aftershocks so far, including one that registered a 5.5 magnitude, and other smaller temblors, USGS said.Chandeliers swung and water sloshed around in swimming pools in the Los Angeles suburbs, witnesses reported, while posters to Twitter reported feeling the quake in Phoenix, Arizona.

Capt. Steve Ruda, a spokesman for the Los Angeles city fire department, said there were isolated power outages and a few people reported trapped in elevators, but no injuries or structural damage were reported.Nine minutes after the Mexico quake, a magnitude 4.1 quake rattled windows in Santa Rosa, north of San Francisco. No damage was reported there, and Susan Potter, a USGS geophysicist, told CNN that was a separate quake from the one that struck in the Baja California desert.The USGS initially reported that the Baja California quake had a 6.9 magnitude. The USGS upgraded the quake about an hour later.

A 6.9 earthquake occured in San Diego6.9 earthquake hit the San Diego area around 3:45pm today, according to earthquake.usgs.gov. It is unclear what kind of damage was done, if any, but it is the third quake to hit with an epicenter in Baja, California this afternoon. Smaller aftershocks also occurred before and after the bigger jolt.
A 3.3 and 4.3 earthquake happened within a half hour of the biggest quake, and news sources are just starting to break the news about the big quake. Apparently the rattle lasted about 12 seconds, and Twitter was blowing up with people commenting on the rumble.

There were a few minor quakes in the San Francisco Bay Area today as well, but with magnitudes of less than 3.0. According to reports, today’s San Diego jolt occurred (16 miles) SSW of Guadalupe Victoria, Baja California, Mexico. The hypocentral depth was 20 miles, according to Stinque.com.

WASHINGTON The U.S. ambassador to Chile says he knows of no American deaths from the earthquake in Chile, but stresses that officials are having a difficult time getting information from the most devastated region of Conception.In an interview by telephone with CBS’s “The Early Show” on Monday, ambassador Paul Simons said, “We do not have any confirmed reports of Americans who have died.” He added that while officials have been able to contact “a few” of the estimated 1,000 Americans in Chile, “information is still very, very scarce.”Simons said that while life is returning to normal in the capital of Santiago, the Conception area near the epicenter of the magnitude 8.8 quake on Saturday suffers from “major devastation,” where power is out and water is in short supply.(AP)

Mexico City An earthquake measuring 8.8 that struck Chile SR 500 times more powerful than the earthquake that shook 7 SR Haiti last month. But the level of death and destruction in Chile sedahsyat not like what happened in Haiti. The number of victims of the earthquake in Chile less than the number of earthquake victims in Haiti. The death toll from the earthquake in Chile for a while just reached 300 people, while the death toll in Haiti through the 200 thousand inhabitants. In Chile, the number of people who lost their homes less than Haiti, and also telephone and communications network could be restored within 5 hours. Why does this happen?

As reported by the Los Angeles Times, Sunday (28/2/2010), explained that the earthquake happened in Haiti is more shallow depth of 10 kilometers and the epicenter was only a few miles of a densely populated area such as the capital of Port-au-Prince. Meanwhile, Chilean earthquake occurred at a deeper depth of about 35 kilometers and centered off the coast of the sparsely populated community. Other causes of, namely because Chile are relatively well prepared to face an earthquake. Past events in 1960, when the strongest earthquake ever SR 9.5 magnitude devastated Chile, became a valuable experience for the country. Schools and even an earthquake exercise routine for students.
