Magnitude 6.3 Earthquake Shakes Northern Chile

SANTIAGO, Chile – The U.S. Geological Survey says a magnitude 6.3 earthquake has struck northern Chile.

The quake, which was moderately deep at 82 kilometers (51 miles), struck at 3:32 a.m. local time Tuesday. The epicenter in Tarapaca was 73 kilometers (45 miles) east of the port city of Arica, and 87 kilometers (54 miles) southeast of the larger Peruvian city of Tacna.

No further information was immediately available.

Magnitude 6.3 Earthquake Strikes Northern Chile: USGS

WASHINGTON, United States – A 6.3-magnitude earthquake struck northern Chile early Tuesday, the US Geological Survey said.

The tremor hit 70 kilometers (43 miles) east of the coastal city of Arica, which is near the border with Peru, the US agency said.

The quake struck at a depth of 82 kilometers, it added.

Chile is one of the world’s most earthquake-prone countries. In the past seven years, it has had three quakes of a magnitude greater than eight.

The 1960 Valdivia earthquake in Chile was the strongest quake ever recorded at 9.5 on the magnitude scale, according to the US Geological Survey.

Chile lies on what is known as the Ring of Fire — an arc of fault lines that circles the Pacific Basin and is prone to frequent earthquakes and volcanic eruptions.

The north of Chile was struck by an 8.3-magnitude quake, followed by a tsunami in September 2015, killing 15 people.

6,1 Earthquake Rattles Tonga

Tonga was hit by strong 6,1 earthquake at 3.04am local time (3.04pm BST).

Damage or injuries have not yet been confirmed on the Pacific nation, which is made up of 169 islands.

No tsunami warnings are currently in alert, according to the Pacific Tsunami Warning Center.

The earthquake struck at a depth of six miles, around 117 miles north-west of the village of Pangai, which is home to 1,800 people.

It struck 154 miles north of Nuku’alofa, which is home to 22,400 people.

6.6-Magnitude Earthquake Strikes Off Alaska: US Geological Survey

WASHINGTON, UNITED STATES: A strong 6.6-magnitude earthquake struck off the west coast of the US State of Alaska Sunday, seismologists said, but no tsunami warning was issued.

The US Geological Survey (USGS) said the earthquake struck at a depth of 111.8 kilometers (69 miles) and 60 kilometers east of the remote Buldir Island in the Aleutian archipelago that is home to some 8,000 people.

“Overall, the population in this region resides in structures that are resistant to earthquake shaking, though vulnerable structures exist,” USGS said.

“The predominant vulnerable building types are unreinforced brick masonry and reinforced masonry construction.”

The Pacific Tsunami Warning Center did not immediately issue any warnings.

“There is a low likelihood of casualties and damage,” USGS added, assigning the event a “Green alert.”

Deep 6.4 Quake Strikes Near Fiji And Tonga

The Pacific Tsunami Warning Centre says there is no threat of a tsunami from a 6.4 earthquake which struck near Fiji and Tonga.

The US Geological Survery measured the quake, which occurred today at 1619 Fiji Time, at a depth of 98 kilometres.

According to disaster response authorities in Fiji, the quake’s epicentre was 846km south east of Suva, which is just to the west of the Tongan trench.

The co-ordinates of the quake are 23.713°S 176.937°W.

New Mexico Earthquake Topples Homes And Causes Fresh Alarm

A strong new earthquake shook Mexico on Saturday, toppling already damaged homes and a highway bridge and causing new alarm in a country reeling from two even more powerful quakes this month that together have killed nearly 400 people.

The US Geological Survey said the new magnitude 6.1 temblor was centered about 11 miles (18km) south-southeast of Matias Romero in the state of Oaxaca, the region most battered by a magnitude 8.1 quake on 7 September.

It was among thousands of aftershocks recorded in the wake of that earlier quake, which was the most powerful to hit Mexico in 32 years and killed at least 90 people.

There was some damage in Oaxaca but no immediate reports of new deaths. The federal police agency posted images online showing a collapsed bridge that it said had already been closed due to damage after the 7 September quake.

Bettina Cruz, a resident of Juchitan, Oaxaca, said by phone with her voice still shaking that the new quake felt “horrible”.

She said: “Homes that were still standing just fell down. It’s hard. We are all in the streets.”

Cruz belongs to a social collective and said that when the shaking began, she was riding in a truck carrying supplies to victims of the earlier quake.

Nataniel Hernandez said by phone from Tonala, in the southern state of Chiapas, which was also hit hard by the earlier quake, that it was one of the strongest aftershocks he has felt. “Since 7 September it has not stopped shaking,” he said.

USGS geophysicist Paul Caruso said the new temblor was an aftershock of the 8.1 quake, and after a jolt of that size even buildings left standing can be more vulnerable.

“So a smaller earthquake can cause the damaged buildings to fail,” Caruso said.

President Enrique Peña Nieto tweeted: “At the moment the greatest damage has been to the Ixtaltepec bridge, which should be rebuilt, and structures with previous damage that collapsed.” He said government workers were fanning out in Juchitan to provide help to anyone who needs it.

Jaime Hernandez, director of the Federal Electrical Commission, said the quake knocked out power to 327,000 homes and businesses in Oaxaca but service had been restored to 72% of customers within a few hours.

Buildings swayed in Mexico City, where nerves are still raw from Tuesday’s magnitude 7.1 tremor that has killed at least 305 across the region. Many residents and visitors fled homes, hotels and businesses, some in tears. At the Xoco general hospital, which is treating the largest number of quake victims, workers ordered visitors to evacuate when seismic alarms began to blare.

That included Syntia Pereda, 43, who was reluctant to leave the bedside of her sleeping boyfriend. Jesus Gonzalez, 49, fell from a third-story balcony of a building where he was working during Tuesday’s quake and was awaiting surgery. But she controlled her emotions, went outside and came back when the trembling was over.

“We are getting used to this,” Pereda said. “Every so often we hear the alarm, you say, well, it is God’s will.”

Alejandra Castellanos was on the second floor of a hotel in a central neighborhood of Mexico City and ran down the stairs and outside with her husband. “I was frightened because I thought, not again!” Castellanos said.

Mayor Miguel Angel Mancera said there were no reports of significant new damage in the capital, and rescue efforts related to Tuesday’s quake were continuing. He reported that two people died of apparent heart attacks during the new temblor.

At the site of an office building that collapsed on Tuesday and where an around-the-clock search for survivors was continuing, rescuers briefly evacuated from atop the pile of rubble after the morning quake before returning to work.

As rescue operations stretched into day five, residents throughout the capital held out hope that dozens still missing might be found alive. More than half the dead 167 perished in the capital, while 73 died in the state of Morelos, 45 in Puebla, 13 in Mexico State, six in Guerrero and one in Oaxaca.

Frida Sofía, age 12: the Mexico City quake ‘survivor’ who was never there

Along a 60ft stretch of a bike lane in Mexico City, families huddled under tarps and donated blankets, awaiting word of loved ones trapped in the four-story-high pile of rubble behind them.

“There are moments when you feel like you’re breaking down,” said Patricia Fernandez Romero, who was waiting for word on the fate of her 27-year-old son. “And there are moments when you’re a little calmer. They are all moments that you wouldn’t wish on anyone.”

Families have been sleeping in tents, accepting food and coffee from strangers, people have organized to present a united front to authorities, who they pressed ceaselessly for information. They were told that water and food had been passed along to at least some of those trapped inside.

On Friday morning, after hours of inactivity blamed on rain, rescuers were readying to re-enter the site, joined by teams from Japan and Israel. Fernandez said officials told them they knew where people were trapped on the fourth floor. It’s the moments between those bits of information that torment the families.

“It’s that you get to a point when you’re so tense, when they don’t come out to give us information,” she said. “It’s so infuriating.”

UPDATE: Mexico Quake Fallout Has Been Personally Disturbing

As mentioned in yesterday’s article, an elementary school had collapsed as a result of the mag. 7.1 quake just south of Mexico City. It is hard for me to report on casualties related to any disaster, but when it comes to children, my emotions become a bit overwhelming. As many of you know, I have two young children, Alexa age 9 and Sophia age 5. Among my activities, I volunteer as a WatchDog at their elementary school (which I encourage every father to participate), giving me a great opportunity to enter-act with these bright beautiful children.

You might have guessed where I have been over the last several days last week… Yes, I got the call to venture off to Georgia dealing with that nasty Irma. Just got a call to head to Mexico, but this time my answer was ‘no’. We all have our limits and or, Achilles heel, mine is children. Perhaps I’m reacting to my own PTSD, or perhaps I’m just getting a bit older, or I just love my kids so much I would rather stay home with them and my wife being damn grateful we are all safe…for this time around.

As an aside, the Mexico City Emergency Management Team is well qualified, and it just so happened they were just completing ‘active scenario training’ at the time of this 7.1 quake.

More than 300 children were studying in their classrooms at Enrique Rébsamen primary school, in Mexico City’s southern Coapa district when the earth started violently shaking.

In an instant, concrete walls and ceilings in parts of the school came crashing down, crushing students as young as first-graders. Neighbors, relatives of the children and even a passing taxi driver rushed toward the giant plume of dust, prying away debris with their bare hands, desperately searching for any sign of life Tuesday afternoon. They worked through the night.

By Wednesday morning, rescuers had carried out at least 25 bodies, twenty-one of them were students with names like Daniela, Diana and Oscar. They were all believed to be 7 or 8 years old and were still dressed in their white and black school uniforms.

Those killed at the school were among at least 230 people who perished across five states in Tuesday’s magnitude 7.1 earthquake. Dozens of buildings collapsed across central Mexico, including large office buildings and apartment towers in Mexico City.

Details of the girl located on Wednesday have not been given. Rescuers detected her after she moved her hand and a hose was lowered to supply her with water.

Civil Protection volunteer Enrique Gardia told the assembled crowd that a thermal scanner had detected several survivors trapped between slabs of concrete.

“They are alive! Alive!” he shouted. “Someone hit a wall several times in one place, and in another there was a response to light signals with a lamp,” he added.

One mother, standing nearby waiting for news of her seven-year-old daughter, told reporters: “No-one can possibly imagine the pain I’m in right now.”

At least 209 schools were affected by the quake, 15 of which have suffered severe damage.

Popocatépetl Volcano Activity

The National Center for Disaster Prevention reported that, so far, there has not been an increase in the activity of the Popocatépetl volcano and remains at Alert Level ‘Advisory’ and Aviation code ‘Orange’.  The most recent report indicated the monitoring systems identified 256 low intensity exhalations, one explosion, as well as 15 volcano-tectonic earthquakes with magnitudes between 1.5 and 2.5.

During the night, no incandescence was noticed on the crater and since the morning of this Wednesday the volcano has been observed with a weak emission of water vapor and gas.

From dawn and up to the time of this report the volcano has been seen with a weak emission of steam and gas. NCDP emphasizes that people ‘Should Not’ go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments.

The scenarios foreseen for this phase are:

Explosive activity of low to intermediate level – Ash fall in nearby towns – Possibility of short range pyroclastic flows and mudflows.

Special emphasis is placed on the following recommendations:

Continue the safety radius of 12 km, so staying in that area is not allowed – Keep the controlled traffic between Santiago Xalitzintla and San Pedro Nexapa through Paso de Cortés – Civil Protection authorities, keep your preventive procedures, in accordance with their operational plans – People, be alert to the official information disseminated.

In case of ashfall, address the following recommendations:

Cover nose and mouth with a wet handkerchief or face mask – Clean eyes and throat with pure water – Avoid contact lenses to reduce eye irritation – Close windows or cover them up, and stay indoors as much as possible.

Popocatepetl Volcano monitoring is performed continuously 24 hours a day. Any change in activity will be reported in due course.

Bali’s Mt. Agung Volcano Threatens to Erupt

A marked increase in the number of earthquakes happening below Mount Agung volcano in eastern Bali, Indonesia, over the past few weeks has authorities keeping a close watch on the situation. Stopping just short of calling for evacuations, the latest alert issued by the national and local government agencies now forbids climbing of the mountain and orders evacuations within 7.5 km of the summit.

Although infrequent, eruptions of Mt Agung have been among the largest of the past 100 years of global volcanic activity. More than 1,000 people died during the last eruption in 1963.

Our ability to predict eruptions has improved dramatically since this last event, so we can hope such a death toll will not occur again.

Mt. Agung is one of many similar volcanoes in Indonesia and the Ring of Fire surrounding the Pacific and eastern Indian oceans. But during its sporadic eruptions, Agung has been one of the most prominent injectors of volcanic ash and sulfur dioxide into the atmosphere.

This type of activity can have effects that are more widely felt than by just the population of Bali.

Earthquakes on the Rise Near Yellowstone Supervolcano

Recent data from the University of Utah shows the northwest corner of Yellowstone National Park has seen a spike in earthquakes. Miles underneath the park sits one of the world’s largest volcanoes, known as the Yellowstone super volcano.

According to FOX31’s sister station, there have been 1,200 earthquakes in the park since the beginning of June. Jamie Farrell, Research Professor of Seismology at the University of Utah, says this is a large swarm, but adds the activity is otherwise pretty normal for the volcanic area.

“We get a lot of calls as to whether people should cancel plans to go to Yellowstone and the answer is decisively no,” he said. “This is how volcanoes act, and it’s pretty normal.”

Researchers say that there are typically between 1,500 and 2,000 earthquakes a year in Yellowstone.
