Recent Earthquakes

On Apr. 5, 2010, its Easter Sunday in San Diego and on a day you'd probably least expect, a 7.2 earthquake. The epicenter struck Mexicali, Mexico. Given that the earthquake took place, there were reports of roughly 19 aftershocks ranging from 3.5 - 5.1. The strong earthquake swayed structures from Los Angeles to Tijuana, killing two people in Mexico, blacking out metropolitan areas, forcing the entire evacuation of hospitals as well as nursing facilities, plus prompting a California border area to shut down its downtown area. People from San Diego as well as Los Angeles to Phoenix, AZ and Las Vegas, NV experienced the earthquake on different levels. This has been among the most powerful earthquakes to hit Southern California in many decades. The earthquake had been felt the hardest throughout Mexicali.

On December 26, 2004 giant forces that had been building up deep within the Earth for more than 100 years had been released abruptly shaking the ground violently and unleashing a series of killer waves that sped throughout the Indian Ocean at the speed of a jet airliner. By the end of the day more than 150,000 people were dead or missing and millions more had been homeless in 11 countries, making it perhaps the most damaging tsunami ever. The epicenter of the 9.0 magnitude quake appeared to be under the Indian Ocean close to the west coastline of the Indonesian island of Sumatra, according to the USGS, that monitors earthquakes throughout the world. The violent movements of sections of the Earth's crust, known as tectonic plates, displaced a massive amount of water, sending tremendous shock waves in every direction. The actual quake appeared to be greatly experienced in Sumatra, the Nicobar and Andaman Islands, Malaysia, Myanmar, Singapore, Thailand, Bangladesh and India. According to the U.S. Geological Study, the magnitude of the earthquake was unfortunately greater than the Richter magnitude appeared to be 9.0. Such magnitude would make this earthquake to be the fourth largest in the world since 1900 and the biggest since the 1964 Alaska earthquake.

On October 17, 1989, at 5:04 p.m. Pacific daylight time, millions of television viewers' world wide had been settling in to look at the third game of the World Series. And surprisingly, instead, people saw their own television set sets go black when tremors hit San Francisco's Candlestick Park. Although the earthquake was centered in a rural section of the Santa Cruz Hills, 100kms towards the south, major damage occurred within the Marina District of San Francisco from the Loma Prieta earthquake. Essentially the most tragic result of the violent trembling appeared to be the fall of some double-decked sections of Interstate 880. The ground motions caused the upper deck to swing, shattering the concrete structure columns alongside a one-mile section of the interstate. Top of the deck then collapsed upon the lower roadway, flattening automobiles as though these were aluminum cans. This earthquake, known as the Loma Prieta tremble due to the point of origins, claimed 67 lives.

During mid-January 1994, fewer than five years after the Loma Prieta earthquake ravaged portions of the San Francisco Bay Area, a major earthquake struck the Northridge area of Los Angeles. Although not the actual fabled "Big One," this specific moderate 6.7 magnitude earthquake left 57 lifeless, a lot more than five,000 seriously injured, and also thousands of people without having water as well as electricity. The damage exceeded billion and seemed to be attributed to a previously undiscovered fault which in turn ruptured eighteen kms (11 miles) underneath Northridge

Earthquake activity has forced more and more people to prepare for possibly the "Big one" that has been talked about for years. The idea seems to have been recently suggested that a huge earthquake may hit California within the near future. Even though there may be no real proof of this happening, the recent earthquake activity cannot be ignored.
