5.4 Magnitude Earthquake Shakes Southers California Today July 7, 2010′ The United States Geological Survey downgraded the earthquake to 5.4.Originally the earthquake was 5.9 and 5.7. There was a lot of aftershocks according to the website of United States Geological Survey. The depth of the earthquake was 8.7 miles and 14 kilometers.The earthquake was felt as far away as Las Vegas.

The strongest earthquakes of the last twenty years to hit California date back to 1992 and 2005 -both with a magnitude 7.2. Borrego Springs California Earthquake 5.4 occured on July 7, 2010 at 4:53PM (PDT) 11:53 (GMT) according to Caltech and USGS. The epicenter was 15 miles northwest of Borrego Springs, California.In San Diego, California skyscrapers swayed.

An earthquake measuring 5.0 degrees on the Richter scale hit on Tuesday Venezuela's Sucre state and there were no reports of casualties or material damage, the head of Venezuela's Foundation of Seismologic Investigations said. Francisco Garces told state-run Venezolana de Television that the earthquake occurred at 9:17 a.m. local time (1347 GMT), some 32 kilometers south of Guiria in Sucre, 400 kilometers east of Caracas.

Garces said that security institutions are on alert for the earthquake, which was followed minutes later by an aftershock of 2.8 degrees. Garces discarded the possibility of an eventual tsunami. Also on Tuesday, an earthquake measuring 5.4 degrees on the Richter scale hit the regions of Maule and Bio Bio in the center-south region of Chile, without causing casualties or material damage.

An earthquake, also known as a quake, tremor, temblor or seismic activity, is the result of a sudden release of energy in the Earth's crust that creates seismic waves. Earthquakes are measured with a seismometer; a device which also records is known as a seismograph.

At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacing the ground. When a large earthquake epicenter is located offshore, the seabed sometimes suffers sufficient displacement to cause a tsunami.

The shaking in earthquakes can also trigger landslides and occasionally volcanic activity. In its most generic sense, the word earthquake is used to describe any seismic event, whether a natural phenomenon or an event caused by humans, that generates seismic waves.

A 6.4-magnitude earthquake hit northern Japan early today, but there was no tsunami warning and no immediate reports of damage, US and Japanese seismologists said. The underwater quake happened at 6:56am (2156 GMT Sunday) off Iwate prefecture, 500 kilometres north of Tokyo, according to the US Geological Survey.

Its depth was estimated at 24 kilometres, USGS said. No tsunami warning was issued by the Japan Meteorological Agency. Around 20 per cent of the world's most powerful earthquakes strike Japan, which has developed one of the most sophisticated tsunami warning systems. Residents routinely hold drills to prepare for major earthquakes.

A moderate earthquake measuring up to 5.2 on the Richter scale again hits the Andaman islands on Friday, Jul 2, Meteorologists said.The quake hit the islands in night around 11:53 pm. However as of now no damages to life, property and tsunami warning is reported.

The quake struck at the depth of 27 kilometres south of Port Blair at a place situated at 9.9° N Latitude and 91.8° E Longitude in the Andaman sea, the Meteorological department said. Indian Ocean islands usually witnesses frequent earthquake and tsunami, resulting a huge lose to life and property.

Research flights are launched over Southern California to try to determine how, or whether, the 7.2 Easter earthquake affected other fault lines.Three months after a magnitude 7.2 earthquake erupted on the U.S.- Mexico border, seismologists are on a quest to determine whether the massive rupture put more pressure on fault lines in Southern California, increasing the likelihood of more temblors.

The Easter Sunday quake was the largest to rock the region in nearly two decades, producing thousands of aftershocks and actually shifting the Earth's crust as much as 10 feet. Preliminary analysis shows that the Mexicali quake placed more pressure on at least two Southern California fault lines: the Elsinore and the San Jacinto. Both those faults run through the Inland Empire and are relatively close to the border fault that produced the big quake.

 A strong earthquake measuring 6.5 degrees at the Richter scale shook southern Mexico on Wednesday morning. According to the U.S. Geological Service (USGS), the earthquake occurred at 2:22 a.m. local time, with a depth of 10 km in Oxaca state, some 480 km to the country's capital of Mexico City. The earthquake was strong felt in Mexico City. So far, there are not reports of damages or victims.

A strong earthquake hit southern Mexico's Oaxaca state early Wednesday, the U.S. Geological Survey reported. The magnitude 6.2 quake rattled the region at 2:22 a.m. local time and was centered about 220 miles south-southeast of Mexico City. The Oaxaca state Civil Protection Agency reported no damage or loss of life. The earthquake was also felt in Mexico City and Acapulco, about 150 miles from the epicenter.

"It was long ... slow waves ... the kind we sometimes feel here," according to a receptionist at the Crowne Plaza Acapulco Hotel. There was no damage at the hotel, she said, adding some people were woken up by the quake and called the front desk to find out what was happening.

NASA radar images show that Calexico, California was moved as much as 2 1/2 feet (80 cm) south as well as pushed down into the Earth by a magnitude 7.2 earthquake that hit Baja California on April 4, 2010. Does that mean that Calexico is now part of Mexico or has the United States just claimed a couple of feet of Mexican land? I’ll leave that to the politicos  to decide.

The April 4th Baja California quake is called the El Mayor-Cucapah earthquake. It was the strongest earthquake to strike that region in almost 120 years. It was centered 32 miles south-southeast of Calexico. Two people were killed and hundreds were injured. Apparently, it also moved the borders of Mexico and the U.S. as well.

 The death toll from a powerful string of earthquakes that shook Indonesia's Papua province last week has climbed to 17, a government official said Monday. "Most of the deaths occurred when a truck carrying 13 people plunged off a cliff because of the earthquake," said Priyadi Kardono, head of Indonesia's national disaster management agency. "There are 2,556 houses badly damaged. We have a team there and aid has already started to be flown in."

At least six earthquakes struck the region during a several-hour period Wednesday afternoon. Four quakes rattled the region within an hour's time. The largest was a magnitude 7.0. The epicenters of the earthquakes were clustered within 90 kilometers (56 miles) of each other and some 180 kilometers (110 miles) north of Enarotali, Indonesia. "People ran out of their houses and headed for higher ground in fear of a tsunami," Denni Siregar, the police chief of the Yapen Island sector, said shortly after the quakes.
