Puerto Rico in Bunkers~~~Could This Take This Long in France or Florida?

Here is the set that was played at the La Isla Bonita 2 Fundraiser for Puerto Rican earthquake relief. It was an amazing night and I hope that this helps you relive it if you were there.
Listen, stream and share, but most of all DANCE!

GUÁNICA, P.R. — Nearly two months after an earthquake sent the population of southwest Puerto Rico rushing into the streets, thousands of people are still slumbering each night under camping tents, on cots, in their cars and in enormous open tents that serve as government shelters.

Long after a 6.4-magnitude earthquake sent powerful shock waves across the island on Jan. 7, the ground continues to shake. Over the past week, 43 earthquakes classified as “significant” have struck, according to the Puerto Rico Seismic Network, part of a prolonged and terrifying series of seismic events not seen on the island since 1918.  A house in the town of Guánica recently collapsed after a fresh 3.8 magnitude temblor.

And while most of the recent aftershocks have been relatively mild — only five over the past week exceeded 3.5 in magnitude — the cumulative damage and constant rattling have left many Puerto Ricans with their confidence deeply shaken.

Hundreds of families are unable to pay for repairs to their ravaged homes. Others are unwilling to trust government inspectors’ assurances that their houses are safe.
“I expected to be relocated to a trailer or a hotel,” said Pedro A. Ramírez, a 65-year-old war veteran who was still staying last week in a government shelter in Guánica with his wife, daughter and two grandchildren. “I am not expecting them to give me a house. But the only way to get assistance for food is by being here, so they force you to be here. It’s a trap.”

The number of earthquake survivors still living outdoors has surfaced as a tricky challenge for local and federal agencies that are struggling to find housing on an island where more than 8,000 homes are in need of an overhaul as a result of the temblors.

More than two years after Hurricane Maria brought devastation that in some places has still not been repaired, emergency management officials facing the latest natural disasters appear to lack cohesive strategies to keep survivors safe and are improvising as they go along, according to a number of local officials, legal advocates and academic analysts who are watching the response.

“If they learned anything from Hurricane Maria, they are not making it apparent,” said Yarimar Bonilla, an anthropologist at Hunter College who has spent extensive time in the camps. “Maybe they learned that they don’t have to do anything and people will sort it out because that’s what they are doing.”

Shelters were located in flood-prone areas, causing some of the dormitory-style tends to be flooded with mud, and more than 150 schools have yet to reopen.  Distrust of the government prompted many people to set up their own camps along busy roads rather than use shelters managed by the authorities.

Mr. Ramírez and his family stayed under a large, three-sided tent provided by the island government. He and his wife took turns keeping watch over their salvaged belongings while they waited to find out whether the Federal Emergency Management Agency would offer enough disaster aid to repair their damaged home. When their 12-year-old grandson had to go to the bathroom, Mr. Ramírez accompanied him: a registered sex offender from his neighborhood was also staying at the shelter.

After almost two months, the family finally gave up on waiting for federal assistance and went to a relative’s house.

“My granddaughter is asthmatic and spent the whole time at the camp coughing,” Mr. Ramírez’s wife, Nancy Santiago, said.

Out of the roughly 8,300 houses that were damaged in the Jan. 7 earthquakes, about 2,500 are uninhabitable, according to the Puerto Rico Department of Housing.
The Federal Emergency Management Agency has so far allocated $20 million to about 8,500 applicants, most of that for home repairs and some to pay for rent.  More than 30,000 people applied.

But government officials insist that at least half of the people sleeping under the stars are responding not to structural damage to their homes, but to the emotional strain of frequent tremors. There were more than 3,000 quakes within about 20 miles of the epicenter of Puerto Rico’s quake in January alone, according to the Puerto Rico Seismic Network.

The U.S. Geological Service said the aftershocks will continue for “years to decades” and that there is up to a 30 percent chance of an aftershock as big as the Jan. 7 quakes.

“Fear is the greatest enemy we have right now,” said Elizabeth A.  Vanacore, a seismologist at the University of Puerto Rico.

Calls to the island’s suicide hotline have soared to up to 1,600 a day, according to the government mental health agency.

“It keeps shaking and the cracks in the house open even more,” said  Edel Santiago, 39, who set camp in a parking lot with his wife, son and 73-year-old mother, who has Alzheimer’s disease.
He said his family was one of many who were denied aid because their homes were certified as safe, a ruling he disagreed with.

“They certified my house as green, even though it has big, ugly cracks,” Mr. Santiago said. “The guy from FEMA said I could not live there, then another inspector came and put a green sticker on it.”

FEMA sent inspectors to nearly 30,000 homes and gave green armbands to any shelter resident whose house passed, though they were still allowed to remain at the shelter. People who disagree with the safety assessment on their house are being offered money to hire structural engineers, said Alex Amparo, FEMA’s coordinator in Puerto Rico.

“You see the green armband, you know their house is OK, but there is an emotional fear they have,” he said. “At this point, our job is not really to judge them, but to help them through that.”
FEMA has spent more than $2 million to help Puerto Rico’s office of mental health services provide help to rattled residents, including counseling to reassure them that it is safe to go home if their house has passed inspection. Counselors are suggesting that some people may feel safer by sleeping in their living room near an escape route.

Despite the hundreds who remain in camps,  most people have returned home as the tremors have diminished in frequency, Mr. Amparo said.

“If I had 800 people sleeping outside last night, I have to get that to zero,” he said in late February.

The Puerto Rico government reported that fewer than 600 people remained outdoors in 24 different official and informal shelters as of last week. But that does not count a large number of people camping out on their own properties.

FEMA records obtained by The New York Times show that as of Feb. 25, the agency still showed more than 3,000 people living in “emergent” conditions, based on information provided in applications for federal aid. This included nearly 600 who said they were staying in their vehicles and 1,603 living in tents.  The bulk of the people outside their homes had been denied aid because they had insufficient damage to their homes or had insurance, the records show.

FEMA records also show that most people who received cash assistance got less than $500.

And although 1,000 families qualified for placement in hotels, just 157 of them have taken the government up on the offer, as people refuse to leave their neighborhoods, Mr. Amparo said.

Jenniffer Santos-Hernández, a research professor at the University of Puerto Rico who has visited the camps, said the authorities have not done enough to provide temporary housing near people’s homes. She visited one community that is building one-room shacks with metal roofs that she said to look like something from a shantytown.

“There is no sense of urgency,” she said. “These are inhumane conditions.”

William Rodríguez Rodríguez, Puerto Rico’s administrator of public housing, said the government’s response plan has been adjusted along the way to deal with problems as they arose. The biggest challenge, he said, has been dealing with a disaster that, unlike a hurricane, does not seem to end.

“This directly affects people’s spirit,” he said. “We are used to an event that once it passed, it’s over and we can recover. In this case, it’s a constant effort.”

Mr. Rodríguez Rodríguez said the Puerto Rico government — which is bankrupt — is offering a combination of options to those with damaged homes, including federal housing vouchers and public housing. There is enough housing supply for everyone, he said, but people in the hard-hit south are going to have a hard time if they insist on staying in their neighborhoods. 

“They have to be open to moving,” he said.

“We are blind, and only the government has eyes,” the leaders said in a statement.

 The 8x12 foot wooden homes with metal roofs will not be suitable for hurricane season, which begins in June

 “We feel safe,” Amelia Vélez said of the temporary wooden homes in the encampment. “But we have to have a Plan B.”

Rosita Leomaris Hernández, one of the leaders, said officials seem oblivious to the many obstacles people face: the waiting list for federal Section 8 housing assistance is often a year-long; apartment rentals require a year lease, and some of the hotels FEMA is using are too close to the epicenter of most of the quakes. People who earn more than $1,000 a month did not qualify for most aid, she said.

“What the people are demanding is help to rebuild their homes,” she said.

In Yauco, Amelia Vélez, 38, and a few dozen members of her family who are appealing their denials from FEMA for money to repair their homes are making do with 8- by 12-foot wooden structures with metal roofs that a local pastor built for them at the edge of a cliff. She likes her new digs but recognizes that hurricane season starts on June 1, and the structures are not suitable for storms.

“We feel safe,” she said among the hammering of nails. “But we have to have a Plan B.”

Take A Look A Puerto Rico After The Two Devastating Earthquakes

A colonial-era church built in the late 1800s has stood in the central plaza of Guayanilla on the southern coast of Puerto Rico for more than 100 years.
On Tuesday morning, shocked locals inspected its ruins. 
“All that’s left is one wall and half of another wall,” Glidden Lopez, a spokesperson for the municipality of Guyanilla told the Miami Herald
Puerto Rico was hit by a devastating magnitude 6.4 earthquake around 4 a.m. Tuesday. It leveled homes, decimated at least one of Puerto Rico’s already-struggling schools, and collapsed an iconic natural rock bridge that had stood on Puerto Rico’s south coast for thousands of years.  
At least one person is confirmed dead, and Tuesday’s tremor — the strongest in 102 years — is only the latest in a series of more than 400 quakes more powerful than magnitude 2 that have shaken the island since late December. 
And the seismic activity is still ongoing: The U.S. Geological Survey reported dozens of aftershocks off Puerto Rico’s southern coast throughout the morning on Tuesday. Preliminary readings indicated that one of those clocked in at 5.6 on the Richter scale, hitting south of the island just hours after the larger quake. 
Gov. Wanda Vazquéz declared a state of emergency Tuesday, and top officials on the island said it was too soon to fully assess how bad the damage was. About 300,000 people on the island are without access to clean water, the governor said at a news conference
The island’s still reeling from 2017’s Hurricane Maria, which destroyed much of the island’s infrastructure. The electrical grid, which even prior to Maria badly needed repairs, hasn’t recovered. Post-Maria recovery essentially ground to a halt last year as federal funds dried up. 
That leaves the island vulnerable to earthquakes like the ones that have hit the island in recent weeks. 
Here’s what we know about the damage the quakes have caused so far: 
  • Puerto Rico’s two largest power plants were damaged, which plunged much of the island into a blackout on Tuesday. The largest had suffered “severe damage,” and might take days to get back online. After Maria, much of the island was without power for 11 months. Already, local officials are warning their residents that it could be weeks before power is fully restored. 
  • Hundreds of public schools have been shuttered due to budget cuts in the last three years in Puerto Rico. One of the ones that was still open, in Guanica, was badly damaged by Tuesday’s earthquake. 
  • The island’s largest hospital in San Juan was briefly without power on Tuesday morning, but Puerto Rican power authority told CBS News it had been restored by around 11 am
  • More than 300 people across Puerto Rico have taken to shelters, unable to return to their either collapsed or heavily damaged homes.
  • In Ponce, another city on Puerto Rico’s southern coast, cops reportedly evacuated 150 people from buildings that were in danger of collapsing, including a nursing home. 
  • Monday’s quake toppled the natural rock arch, Punta Ventana, a popular tourist spot in Guayanilla, on the island’s southern coast. “We’ve lost an important symbol of our town and our natural heritage,” Guayanilla Mayor Nelson Torres Yordán said, according to the Washington Post
All this has prompted the island’s government to ask for the Trump administration for a federal disaster declaration. The Federal Emergency Management Authority says that that request is currently “under consideration.”

How Portugal's Biggest Disaster Initiated A Scientific Discipline for a State Of Readiness

Why You Should Care?
Because a 1755 quake shook thinkers and movers into serious action.

Capital City


Most of the population of Lisbon was in church when the first quake hit. It was the morning of All Saints Day, 1755, and this was the most prominent city in one of the world’s most powerful countries. None of that mattered, of course, when the shaking started.

The Lisbon quake is still a defining moment in the city’s history. Estimated to be an 8.5 magnitude or higher on the modern-day Richter scale, it was followed by two smaller quakes and a tsunami, as high as 15 meters, then by days of fires that engulfed the city. Hundreds of aftershocks happened over subsequent months. No official death count exists, but sources both contemporary and modern estimate somewhere between 10,000 and 60,000 people died (the population numbered about 1 million at the time). About 82 percent of the city’s buildings were destroyed, among them churches, cathedrals, royal palaces, and the opera house.

That the rich and the outwardly godly weren’t spared in the quake may have been one factor that spurred what amounted to an existential crisis among some Europeans. While many did turn to religion in the time of crisis — and 18th-century Portugal had its share of spiritual leaders blaming the quake on human sin, a phenomenon that persists today — science and philosophy also had their part to play. Thinkers like Voltaire, Rousseau and Immanuel Kant (there’s more on Kant; keep going) all meditated on the earthquake and what it meant for humankind and its trust in fate.

The birth of seismology — the science of earthquakes and their accompanying phenomena — is often traced right back to 1755, and specifically to one man: Sebastião José de Carvalho e Melo, the Marquis of Pombal. Technically serving as Secretary of State to King Joseph I, Pombal took on a much larger role in the aftermath of the quake, explains Mark Molesky, author of This Gulf of Fire: The Destruction of Lisbon, or Apocalypse in the Age of Science and Reason. “The king was kind of shell-shocked — he and his family were almost killed by this,” Molesky says, “and he essentially gave power to Pombal, and Pombal ruled in his name for about 20 years.”

It was Pombal who ordered that a questionnaire about the earthquake be filled out for every district of the city: How many aftershocks? Did the sea rise or fall before the tsunami? Which parts of the city were damaged by fire, and to what extent? That data, still housed in Portugal’s archives, has allowed modern researchers to examine and reconstruct the details of the 1755 quake with the benefit of modern scientific theory.

This is not to say that the scientists of the day were on the right track when it came to the earthquake’s causes. Astronomer John Michell put forth an elaborate theory involving a wave of force, much like a sound wave, perhaps caused by a volcano superheating rock layers in the earth. Immanuel Kant — yes, that one — appropriated ancient theories invented by Aristotle, who thought quakes might be caused by wind passing through underground caverns. Kant, feeling that winds weren’t strong enough to cause such devastation, decided it might be explosions in underground caverns.

Of course, the study of plate tectonics has given us insight into what actually causes earthquakes. But the plot of Dwayne “the Rock” Johnson’s classic San Andreas aside, that knowledge hasn’t actually made quakes easier to predict. Knowledge is power, except when it isn’t: The scientific quest kicked off in Lisbon 263 years ago still doesn’t have the answer it was truly searching for.

Pombal’s contributions didn’t lead to much prevention. But preparation, that he could do. Tasked with rebuilding Lisbon almost from the ground up, Pombal rebuilt many neighborhoods on a system of logical grids in an architectural style still known as Pombaline — notable for being some of the first modern architecture to incorporate anti-seismic safety features, like wooden frames that could sway without breaking. The new buildings, which also used wooden lattice frames meant to evenly distribute the force of a quake, and doors, windows, and walls were built to standard sizes. And soldiers were ordered to march heavily around buildings to stress-test them. Note: There hasn’t yet been an opportunity to test this in real life — 1755 remains the biggest earthquake Portugal has ever experienced.

Pombaline Lisbon has been placed on a list of candidates to become a World Heritage site, not just for its now-iconic orderly architectural style, but as a commemoration of Portugal’s contribution to being prepared.

Scientists ] Water Extraction Caused Deadly Earthquake in Spain Last Year

Spain Man Made Quake

MASSIVE extraction of groundwater helped unleash an earthquake in southeastern Spain last year that killed nine people, injured at least 100 and left thousands homeless, geologists has said.
The finding added a powerful piece of evidence to theories that some earthquakes were human-induced, they said.
Seismologists were surprised by the May 11, 2011 earthquake which happened 2km northeast of the city of Lorca.
The quake struck in the Eastern Betics Shear Zone, one of Spain's most seismically active regions, where there has been a large number of moderate-to-large temblors over the past 500 years.
But the May event was unusual because it was so devastating and yet so mild - only 5.1 magnitude - in terms of energy release.
Researchers led by Pablo Gonzalez of the University of Western Ontario in Canada probed the mystery.
Reporting in the journal Nature Geoscience, they found that the quake occurred at a very shallow depth, of just 3km, so the shockwave swiftly reached the surface with little to dampen it on the way.
The quake also happened on a complex but dormant fault that ripped open after water had been extensively pumped out of a neighbouring aquifer, causing a domino effect of subterranean stresses, they said.
Gonzalez' team first used ground-radar imaging by the European satellite Envisat to build a map of how terrain around Lorca changed before and after the quake.
The picture confirmed that the event had occurred on the so-called Alhama de Murcia fault, which slipped between 5cm and 15cm.
They then investigated the Alto Guadalentin Basin, an aquifer lying just 5km south of the fault, where they found widespread evidence of subterranean subsidence from water extraction.
Between 1960 and 2010, the level of groundwater from this aquifer fell by at least 250m, according to records from local wells.
A computer model put together by the team suggests what happens: lowering of the water table caused part of the crust, located next to the Alhama de Murcia fault, to break.
This led to an "elastic rebound" of the crust that in turn cranked up horizontal pressure on the fault, bringing it that much closer to rupture.
The investigation adds to anecdotal evidence that human activities, ranging from exploration for shale gas, quarrying and even water reservoirs, can cause quakes.
"Our results imply that anthropogenic [man-made] activities could influence how and when earthquakes occur," the study said.
In a commentary, Jean-Philippe Avouac, a geologist at the California Institute of Technology said water extraction at Lorca probably accelerated a natural process of stress accumulation rather than unleashed the earthquake by itself.
Even so, "the consequences are far-reaching", Professor Avouac said.
He pointed to carbon storage, a still-experimental technique in which carbon dioxide from a fossil-fuel power station is pumped into underground caverns rather than released to the atmosphere, where it would add to global warming.
"For now, we should remain cautious of human-induced stress perturbations, in particular those related to carbon dioxide sequestration projects that might affect very large volumes of crust," Professor Avouac said.
"We know how to start earthquakes, but we are still far from being able to keep them under control."
