Rose Canyon fault is MORE dangerous than thought

The Rose Canyon fault in California generates powerful tremors almost twice as frequently as previously believed, and it could trigger a 7.4 magnitude earthquake. Pictured – Destruction after the magnitude 6.7 Northridge earthquake hit Los Angeles in 1994 (stock image)

If you live in California then you’ve heard the saying quake country. We’ve all experienced a major quake in our life time. I remember the one quake that scared the life out of me.

Buildings collapsed as a result of the earthquake

It was January 17, 1994 the time was 4:30 on Martin Luther King Jr day, no school or work that day, saved thousands of lives in my opinion. Just imagine all those people that would have been on the freeways that collapsed! I didn’t sleep for days because I was scared that there would be another earthquake but stronger. 

According to seismologist Tom Rockwell “A powerful quake in the mid-to-upper 6s could cause liquefaction around San Diego and Mission bays and locally in Mission Valley, and cause the land to be offset across the fault, which would damage buildings.” The Rose Canyon fault stretches almost 40 miles, from San Diego bay in the south before veering offshore near La Jolla and reaching as far north as Oceanside.

A New System Could Text You 30 Seconds Before An Earthquake Hits

It’s been 23 years since the last major earthquake shook Los Angeles and caused some $10 billion in property damage. Now, a consortium of seismologists from universities along the west coast are working under the U.S. Geological Survey to build an early warning system for future earthquakes.

So, how does an earthquake warning system work? First, during an earthquake, there are two kinds of tremor waves: P waves and S waves. P waves are the initial tremors, and are less significant than the secondary (and much more severe) S waves. Furthermore, P waves travel at the speed of sound, meaning that modern GPS and communication systems travel faster than earthquakes. “That means it would take more than a minute for, say, a magnitude 7.8 earthquake that starts at the Salton Sea to shake up Los Angeles, 150 miles away, traveling on the state’s longest fault, the San Andreas,” adds the Los Angeles Times. And in that minute, sensors along the fault and around the Southland can detect the changes and begin broadcasting alerts.

Here’s What an Earthquake Looks Like Underwater

Have you ever wondered what an earthquake looks like under water?

Well, a group of divers in the Philippines found out first-hand. While filming their dive, an earthquake that measured 5.6 on the Richter Scale shook the bottom of the ocean. Jan Paul Rodriguez was holding the camera when the earthquake occurred.

“It felt like there was a huge propeller of a big boat turning around directly above us,” he said to Newsflare. “We heard underwater the trembling of rocks under the ground and we felt the shock wave, it hurt our ears, feeling heavy breathing and sudden changes in pressure. The seabed pumped up and down immediately followed by a strong shaking of the ground and small rocks falling.” For more on this click here.
