Strong Earthquake Hits Near the Philippines

A strong earthquake hit tonight right off of the coast of Mindanao measuring to be 7.2. People have been advised to stay away form the coast as much as possible incase of more seismic activity and also incase of large waves that could inflict damage. So far there have been no immediate reports of severe damage or casualties, so hopefully it stays that way. The Pacific Tsunami Warning Center reported that there was a huge risk for large waves that could extend out to 190 miles. The Philippines weren’t too concerned about this earthquake because due to their location around the ring of fire. The Philippines are used to getting large earthquakes every year so a 7.2 earthquake that hit off the coast, which didn’t inflict a lot of damage didn’t concern the authorities too much. They even decided against sending out a tsunami warning, believing it wasn’t necessary. The earthquake;s epicenter also was incredibly deep in the ocean, making it more difficult to feel the earthquake on land.

6.9 Magnitutude Earthquake hits Chile

The strong 6.9 magnitude earthquake hit about 85 miles off the west coast of Chile on Monday, April 24.  Fortunately, the “quake-prone” nation was spared from any damage.  Although the epicenter of the earthquake was quite far from land, its focus was quite shallow, thus allowing it to be felt hundred of miles away.  If this earthquake had been closer to land, the 6.9 magnitude could have been responsible for much more sever damage.

The nations tsunami alarm even sounded during the earthquake since the quake hit out at sea.  At one clinic just north of Valparaiso, “people ran from the facility carrying children” and some of them headed for the hills to be above sea level if a tsunami did hit.  Officials soon cancelled the tsunami warning.

There were no reports of structural damage, but some cellphone networks were down.

CASE STUDY SUMMARY_WILLIAMS

I wrote about the Gujarat Earthquake which occurred on January 26, 2001. Fun fact: that day was also India’s 52nd Independence Day anniversary. I had never heard about this event, I stumbled across it when searching for topics to write about.

The Gujarat quake was a 7.7 magnitude quake which occurred in the morning of January 26, and it lasted for over two minutes. The epicenter of the quake was only 24 km deep, so the seismic waves did not have much time to dissipate before the broke the surface. This quake was the second most devastating quake in all of India’s recorded history, with 20,000 left dead, over 150,000 left injured, and over 400,000 displaced or homeless. The quake was followed by over 400 aftershocks felt all over the Gujarat state, as well as the rest of the country of India. These aftershocks continued for up to two months after the quake. This specific quake was caused by the Indo-Australian plate subjecting beneath the Eurasian plate,  also known as a thrust fault.

There was little to no preparation or mitigation for an earthquake of this size in the Gujarat state, which escalated the amount of damage. After the quake, buildings were found to have been lacking basic structural support, or didn’t meet the local building codes. Some engineers and building managers were found criminally negligent because of this, because of claims that more life could have been saved if the buildings were properly constructed.

Once the Indian government saw the magnitude of the destruction of the Gujarat state, relief aid was administered and help poured in. Once the general emergency phase was complete, the Government of Gujarat instated a new disaster management and preparation program. From this, The Gujarat State Disaster Management Authority was created, and still remains to this day. The authority switched from a pro-disaster oriented intervention to a pro-active prevention, mitigation, and pre disaster preparedness. Citizens are now better aware of hazards that come with a potential earthquake, and even though a quake so large happening again in the Gujarat state is slim, it is important to be prepared for the worst.

 

Chile Earthquake

An earthquake of a magnitude 7.1 hit 22 miles off of the west coast of Chile, near Santiago, the capital of Chile at a shallow depth of 6.2 miles below the sea, and about 85 miles. Chile is also well adverse with deadly earthquakes. There had been two significant aftershocks of 5.0 and 5.4.

A magnitude 7.1 quake is considered major and is capable of causing widespread and heavy damage, but the effects of this one would have been tempered because it was offshore.

Fortunately, there seems to be no immediate damage yet, but there are still some ongoing assessments taking place. There had been talk of ,mobile networks being down, but that is to be expected.

Thankfully there have been no reports of any deaths or many injuries.

Chilean authorities had initially ordered a preventive evacuation of the coastal area near Valparaíso, in the off chance of a tsunami, but canceled it shortly afterwards.

The order of a preventive evacuation caused alarm to the people of Chile and stayed with them even after the cancelation of it.

There have also been reports on some landslides in a few places.

Chile Earthquake

An earthquake with a 7.1 magnitude hit the west coast of Chile a couple of days ago. There was no immediate danger reported nor are there signs that there will be a tsunami. Originally, the authorities enforced an evacuation plan but later canceled it due to the Pacific Tsunami Warning Center saying that there will not be a tsunami. Yet, residents were still panicking. Although this is a major earthquake, the effects were tampered due to the fact that it hit the coast. Two aftershocks were reported: one with a magnitude of 5.0 and the other was a 5.4. Since the country runs along two tectonic borders, they are hit by huge earthquakes a lot.

Earthquake and aftershocks hit off coast of Chile

On April 24, an earthquake with a magnitude of 7.1 struck off the coast of Chile, which mainly affected the capital of Santiago. Two major aftershocks were felt from the earthquake,however it was determined that the quake would not cause a tsunami. Before this was determined, the coastal town of Valparaiso was meant to be evacuated, since it was the village closest from the center of the quake. Once the Pacific Tsunami Warning Center determined there would not be a tsunami, the evacuation order was lifted. Even though a 7.1 quake is considered a major earthquake, the effects were minimal and its thought to have been because the quake was centered far offshore. The aftershocks were recorded at magnitudes of 5.0 and 5.4. These were also felt in the capital city of Santiago. Even though the original quake and the aftershocks were fairly strong, only minimal structural damage was reported.

Tremor Sequence Of Chilean Coast

A 7.1 magnitude tremor has just been reported some 30km off the coast of Valparaiso, Chile.  The quake was broadly felt in the capital of Santiago, which is 100km inland from the coastal city.  Severe damage has yet to be reported.  Chilean authorities initially ordered a preventative evacuation of the coastal area near Valparaiso, around 60 miles west of Santiago, in case of a tsunami, but cancelled it shortly afterward.  This tremor closely follows an abnormal sequence that registered eight magnitude 5 earthquakes followed by 6 “aftershock” tremors measuring between 5.0 and 6.0 in magnitude.  In terms of magnitude and frequency, this sequence is unique since aftershock tremors are generally much weaker than the initial quake.  Seismic activity is expected to gradually increase of the Nazca plate continues to subduct under the deformed and faulted South American plate.

A small earthquake hit central California earlier today.  About 3 miles east of Santa Barbra, California, a little after 11 am local time the quake rattled the area. The magnitude was clocked at 3.6 according to the U.S. Geological Survey, and there has not been any reports about damages or injuries so far. There has been an influx of reports from hundreds of people on the geological survey’s website saying that they have felt the shaking nearly 60 miles north of the of Santa Barbra in Lompoc and as far south as Los Angeles County.

In addition, there was another earthquake of the same magnitude 3 km outside of Montecito, California at around 11:30 am local time. This may be why the geological survey website had reports of shaking so far south, but at this point it’s hard to tell.

 

2 earthquakes hit western Turkey

https://www.washingtonpost.com/world/europe/2-earthquakes-hit-western-turkey-cause-panic-in-the-streets/2017/04/21/e8f3524a-26a4-11e7-928e-3624539060e8_story.html?utm_term=.a2f35cf9a211

Turkey has reported that 2 earthquakes hit the western province of Manisa earleir today. These earthquakes had preliminary magnitudes of 4.9 and have caused panic in the streets. The first earthquake was centered in the town of Selendi and hit at 4:16 p.m local time, according to the government’s crisis center. The second quake hit about an hour later in the town of Sehzadeler, which was reported as being more shallow. The local media reported that the second earthquake begun some pandamonium, as residents rushed the streets in a panic.

There has not been any damage reported so far. Turkey lies on active fault lines, so the occurance of earthquakes is not a rare one.

Silverton earthquake preparedness event set April 27

The realization that natural disasters is a global fact occurred to the people of Silver Falls State Park after a magnitude 2.5 earthquake struck on December 21st. No damage happened following this earthquake. But this event rose the question, what if it had been stronger?

“Answers to such questions will be coming to Silverton as a legion of public-safety entities team with the American Red Cross in “Prepare Out Loud,” an earthquake and disaster-preparedness presentation fair set for 7 to 8:30 p.m. Thursday, April 27, at Silverton High School, 1456 Pine St.”

This event is free to the public and is helping raise awareness on how to prepare for such an event. The seismic activity that can occur along the Cascadia Subduction Zone is the prime focus on how to prepare for and how to recovery from a major earthquake that is prone to the area.

This is a great example of how this community is being proactive and preparing for a disaster to strike. This awareness and preparation could save lives and hopefully help for efficient recovery.
