earthquakes

It was a Fourth of July Holiday weekend for the Central and South Coast no one will be forgetting soon, with nature topping the biggest fireworks shows with a reminder of the power of earthquakes. Seismologists say this is a new wakeup call for quake preparedness, ranging from securing heavy items like bookcases, to having emergency supplies on hand. It also highlights another form of preparedness: earthquake insurance.

People on the Central and South Coasts are still talking about the latest series of earthquakes to hit Southern California. A magnitude 7.1 quake centered near Ridgecrest, in the Mojave Desert was felt throughout our region.

A massive magnitude 7.1 earthquake in the Mojave Desert rocked much of California Friday night, and was felt throughout the Central and South Coasts.

There was a magnitude 5.0 quake at 8:16 p.m., followed by the 7.1 at 8:19 p.m.  The Thursday morning 6.4 quake in the same area near the city of Ridgecrest is now being called a foreshock of Friday night's quake.

What seismologists say was the largest earthquake to hit Southern California in 20 years rocked the region Thursday morning, and was felt on parts of the Central and South Coasts.

The U.S. Geological Survey says it was a magnitude 6.4 quake which hit at 10:33 a.m.  It was centered in the Mojave Desert, near the community of Ridgecrest.  It's about 150 miles northeast of Los Angeles.

Could an app in your smartphone soon give you a critical few seconds of warning that a major earthquake is on the way?

Los Angeles County has unveiled its app, and Ventura County is working to become a part of the system.

The new app is called the “Shake Alert LA” app. It’s linked to the U.S. Geological Survey’s Southern California network of quake sensors.

A pair of earthquakes rocked some of the Channel Islands.

A magnitude 3.3 quake hit the San Clemente Island area at 10:58 a.m. Thursday, followed by a 3.0 at 11:14. Both quakes were centered about six miles southeast of the island. San Clemente Island isn’t open to the public, because the 56 square mile island is home to some military facilities.

There are no reports of damage, or people feeling the quakes onshore. San Clemente Island is about 60 miles southwest of Dana Point, in Orange County.

An isolated part of the Channel Islands was rocked by a series of small earthquakes Tuesday.

Three quakes all registering between magnitude three and four hit early Tuesday morning, all centered about six miles southwest of San Clemente Island. That’s about 110 miles southeast of Ventura.

Small Earthquakes Rattle Central, South Coasts

Apr 9, 2018

There have been a series of small aftershocks off the South Coast in the wake of last Thursday big magnitude 5.3 quake in the Channel Islands.

There was a magnitude 2.4 quake south of Santa Cruz Island on Friday, and a 2.6 on Sunday. Also on Sunday, there was a magnitude 2.1 quake northwest of the island. Only a handful of people reported feeling the microquakes. They didn’t cause any damage.

It’s high brush fire season on the Central and South Coasts, and that’s creating a lot of concern about the potential for dangerous blazes.

But, government leaders and public safety officials say there’s the potential for an even larger scale disaster which looms in the background: A mega-earthquake. Democratic State Senator Hannah-Beth Jackson of Santa Barbara chaired a hearing in Sacramento to look at the question of how prepared are we for a huge temblor.

It’s a little known tectonic plate in the Pacific Ocean some 300 miles off the Pacific Northwest.

But, a UC Santa Barbara researcher says we need to learn more about it because it has the potential to trigger mega-earthquakes, and tsunamis.

There’s been a series of small earthquakes off the Central Coast.

There have been five quakes in the last week off of Lompoc, but only three were strong enough to be felt by people.

There was a magnitude 3.0 quake at 9:30 Wednesday night, centered 20 miles southwest of Lompoc. A magnitude 3.5 quake, the strongest in the series, hit at 7:45 Thursday night. No damage was reported.

A new study which shows a number of state courthouses could be at risk of collapse during a major earthquake includes some on the Central and South Coasts.

The list shows more than 100 courthouses statewide could suffer substantial damage, and cause a serious loss of life without costly upgrades.

Parts of the South Coast were rocked by a series of small earthquakes Tuesday night.

A pair of earthquakes rocked parts of the South Coast Sunday morning.

The first quake was a magnitude 3.5 temblor, and hit at 10:55 a.m.  It was centered near Montecito.  

The second one, a magnitude 3.1 earthquake, occurred at 11:56 a.m.  It also had an epicenter  near Montecito.  No damage was reported.

An earthquake fault in Ventura and Santa Barbara Counties may be much more dangerous than thought.

A team of researchers has just completed a study about the makeup of what’s called the Ventura-Pitas Point fault. They say it’s closer to the surface than previously believed, which means stronger shaking and more damage during a major quake.
