From NPR: Powerful Earthquake Roils Central Mexico, Leaving At Least 42 People Dead
Powerful Earthquake Roils Central Mexico, Leaving At Least 42 People Dead September 19, 2017 3:41 PM ET By Colin Dwyer

Updated at 5:33 p.m. ET

Thirty-two years to the day after an earthquake killed thousands of people in Mexico, a powerful quake rattled the country's central region Tuesday. Buildings shivered in Mexico City, shattering facades and sending clouds of dust skyward.

Residents who just hours before had taken part in large simulated earthquake drills to mark the anniversary emptied into the streets when the real quake struck.

In its preliminary assessment, the U.S. Geological Survey said the magnitude 7.1 earthquake's epicenter was just over 3 miles east-northeast of Raboso, in the state of Puebla some 75 miles southeast of Mexico City.

At least 42 people were killed in the neighboring state of Morelos, according to a report issued by Gov. Graco Ramirez. It was not immediately clear how many others had died in the surrounding areas.

"I could barely stand up. There was glass falling everywhere. I really thought the building was going to fall," reporter Emily Green told NPR from Mexico City. "It was a terrifying experience."

Photographs depicted rescue workers wheeling away residents on stretchers, though it was not immediately clear how many people were injured or killed in the capital city.

As NPR's Jon Hamilton notes, the densely populated city is "especially vulnerable to earthquakes, because much of it is built on a former lake bed, which can amplify the effects of distant quakes."

Videos purported to show buildings shaking under the strain, including a whole office building in the neighborhood of Roma Norte.

"We don't have an estimate yet from authorities of how many buildings — but just photos and videos from people in the street show there are many buildings collapsed so far," reporter James Fredrick told NPR. "The civil protection agency of Mexico City has confirmed that they're beginning excavation work for people trapped inside collapsed buildings."

Another problem loosed by the quake: Gas leaks have been reported across the city, some of which have already resulted in fires, according to Fredrick.

The earthquake also comes less than two weeks after a massive temblor struck southern Mexico, killing dozens of people.

The 1985 earthquake that officials were marking Tuesday left thousands dead and parts of Mexico City in ruins. Univision's Enrique Acevedo noted that a national earthquake drill was scheduled for 1 p.m. local time.

"There are lots of people on the street and folks crying, a little bit beside themselves," Green said.

This is a developing story. Some things that get reported by the media will later turn out to be wrong. We will focus on reports from police officials and other authorities, credible news outlets and reporters who are at the scene. We will update as the situation develops.

Another 6.4 earthquake or aftershock hit Oaxaca this morning; strong tremors felt in Mexico City.

https://www.rt.com/news/404298-mexico-e ... hits-usgs/

Earthquake warning sirens are currently sounding in Mexico City while the head of the city government has advised that emergency protocols have been activated following a 6.4 temblor in the city of Ixtepec in the southern state of Oaxaca.

Initial reports from the Mexican Seismological authority said the quake struck at 07:53 am local time at a depth of 10 kilometers with an epicenter approximately 12 km north of the City of Ixtepec. This is around 530km south of Mexico City.

Heard this on NPR earlier this evening, been waiting for it to show up on the website so I could share (it's short, 3:11 minutes). I need to hear stories like this. Not only does it restore my faith in humanity, but affirms the kind of role I hope to play if a truly serious natural disaster ever hits my part of the world. This is why I prep.

That's the trouble with earthquakes. They go on for weeks and months after the initial big quake. The worst day I experienced from the Northridge quake was one afternoon about three weeks after. I was in a small store cleaning out the breakage and resetting the soda cooler as aftershocks kept rolling through every few minutes . Some strong enough to knock the shelves back down as the store owner was on the phone alternately pleading, raging and sobbing to different vendors and financial/insurance companies trying to get deliveries or other essential services for his building.
As of now I bet you got me wrong

From CNBC: California prepping for 'limited public roll out' next year of its quake early warning system
California prepping for 'limited public roll out' next year of its quake early warning system

The West Coast's earthquake early warning system known as ShakeAlert is in the testing stage, although California plans a "limited public roll out" in 2018.

Funding the warning system has been a challenge and the Trump administration's 2018 budget request failed to include money for it.

The House agreed to restore funding for quake warning as part of a package of spending measures passed this month, and the bill is now in the Senate.

Mexico City's devastating 7.1 quake on Sept. 19 killed more than 220 people but the capital city's early warning system may have saved lives.

Jeff Daniels @jeffdanielsca Published 6 Hours Ago CNBC.com

Blaring sirens from a public warning system for incoming earthquakes in Mexico City may have helped save lives this month but the U.S. West Coast lacks a similar system and funding has been a challenge.

President Donald Trump didn't provide funding for the seismic warning system known as ShakeAlert in his 2018 budget proposal. But a bipartisan effort is underway in Congress to restore funding the West Coast earthquake early warning system, and it is now in the Senate's hands.

"We're really behind here in the U.S.," said Richard Allen, director of University of California-Berkeley's Seismological Laboratory. He notes that Mexico's quake warning system was installed in the 1990s and Japan's been running one since 2007.

Work on the earthquake early warning system started a decade ago as a collaboration between the U.S. Geological Survey and several universities on the West Coast that run the seismic sensor networks.

Today, the ShakeAlert system remains in the testing stage, although California is making preparations for a "limited public roll out" in 2018, according to Ryan Arba, branch chief of the earthquake and tsunami program at the California Governor's Office of Emergency Services.

Yet a wider roll out to the general public is still years away since current public alert infrastructure networks for things such as flash floods and hurricane weather alerts are considered too slow for effective warning on earthquakes. Existing cellular towers could be used to send alerts to smartphones, but consumers might need new handsets to support the added capabilities.

"There are challenges doing a full public roll out, such as the ability to link up with people's mobile phones in a way that doesn't compromise the system," said Arba. "So much data has to go through at one time in order to deliver this alert. It ends up becoming a bandwidth issue."

According to the California official, the state is working with cell communication providers and the handset developments to overcome the technology hurdles.

Depending on the location of a tremor, the earthquake warning time can range from seconds to minutes. It would send alerts to give people time to shelter under a desk or table, or hold onto something to potentially avoid injuries during the shaking.

Scientists estimate the public in L.A. could get about a minute warning if a major earthquake were to occur along the southern end of the 800-mile San Andreas fault. Similarly, if it starts in the northern end of the feared fault, the San Francisco Bay area would get about a minute's time of warning.

When the rupture starts closer to the city, though, that means there would be less warning.

In the case of Mexico City, the magnitude 7.1 quake on Sept. 19 that killed more than 220 people was centered about 76 miles from the capital city and the warning sirens gave people about 15 to 20 seconds advance notice before the shaking started — enough time for some to flee buildings and get to safer spots. Some credit the warning sirens with saving lives.

"There's video of people evacuating with the sirens going and then the buildings collapsing, clearly demonstrating the utility of the warning system," said Allen.

The Berkeley seismologist pointed out he's traveling to Mexico City next week as part of a fact-finding team to talk with both the operators and the users of the early warning system. "We want to learn how it performed and how people used it so that we can hopefully learn some lessons that we can apply here in California," he said.

At present, about 200 beta testers in California receive earthquake early warning alerts from the prototype system, including researchers, scientists, key agencies, and companies such as Disneyland in Anaheim. Bay Area Rapid Transit, the commuter rail system in the San Francisco Bay area, uses the alerts to automatically slow or stop the trains prior to the shaking.

California has a goal of about 1,000 seismic sensors statewide for a complete build-out of its early warning system. The state is at the halfway point in terms of reaching that goal.

In April, the Pacific Northwest Seismic Network, which operates from the University of Washington, announced it joined ShakeAlert and would be issuing warnings of incoming earthquakes to pilot users in Oregon and Washington. The list of participants invited for the Pacific Northwest testing includes large corporations such as Boeing, Microsoft, Intel as well as hospitals, utilities, transit agencies and emergency managers.

Funding for the early warning system has come from the federal government, the state of California, as well as other sources. The federal government has spent more than $23 million already to improve ShakeAlert. The USGS estimates it will cost another $38 million to completely build out the system on the West Coast, and roughly $16 million annually to run it and maintain it.

In May, the Trump administration submitted a fiscal 2018 budget request that targeted the USGS with cuts. And it didn't include $10.2 million, the amount provided by Congress in fiscal 2017, to support development of the agency's quake warning system.

However, Republican Rep. Ken Calvert, who chairs a subcommittee determining the spending levels for the USGS, led an effort in the House to restore funding. A bill that funds the USGS and other agencies was included in a package of spending measures that was approved by the House on Sept. 14. That bill is now pending in the Senate.

"Nothing is more important than the safety of our families and communities, and making strong investments in the right technology to detect natural disasters today could save countless lives and help prevent massive economic losses in the future," Sen. Patty Murray (D-WA) said in a statement to CNBC. "That's why I've long supported robust funding for Washington state's early warning system and fought back against President Trump's deep cuts to our disaster preparedness infrastructure."

Meantime, Sen. Maria Cantwell (D-WA) along with the senators from California and Oregon all signed a letter earlier this year to urge the subcommittee overseeing Interior Department appropriations to increase the USGS's earthquake-related programs. Specifically, they urged the panel include at least $16.1 million for development, operation and maintenance of the West Coast ShakeAlert system.

The Senate Appropriations Committee has not yet debated its version of the bill that funds the earthquake early warning system. But one insider expressed confidence the committee would reject the president's proposed cut to the USGS quake warning program.
