New Concerns Over Earthquakes In Oklahoma Near Vast Oil-Storage Facility ( 103 writes: The NY Times reported on October 14, 2015 that a magnitude 4.5 quake struck Saturday afternoon about three miles northwest of the Cushing Hub, a sprawling tank farm that is among the largest oil storage facilities in the world, now holding 53 million barrels of crude with a capacity for 85 million barrels. The Cushing oil hub stores oil piped from across North America until it is dispatched to refineries. The Department of Homeland Security has gauged potential earthquake dangers to the hub and concluded that a quake equivalent to the record magnitude 5.7 could significantly damage the tanks and a study by Dr. Daniel McNamara study concludes that recent earthquakes have increased stresses along two stretches of fault that could lead to quakes of that size. "It's the eye of the storm," says Dana Murphy, vice chairman of the state's oil and gas regulatory body, the Oklahoma Corporation Commission.

"When we see these fault systems producing multiple magnitude 4s, we start to get concerned that it could knock into higher magnitudes," says Daniel McNamara, author of a paper published online that a large earthquake near the storage hub "could seriously damage storage tanks and pipelines." "Given the number of magnitude 4s here, it's a high concern."


A Powerful 8.3-Magnitude Earthquake Strikes Off Chile's Coast 56

wooferhound writes: A powerful 8.3-magnitude earthquake struck off Chile's coast on Wednesday, according to a preliminary assessment from the U.S. Geological Survey. The quake's epicenter was about 54 kilometers (34 miles) west of Illapel, Chile, USGS said. It occurred around 7:54 p.m. (6:54 p.m. ET). Chile's national emergency agency issued a tsunami alert, ordering evacuations in coastal areas from Arica to Puerto Aysen.

Japan To Restart Nuclear Power Tomorrow After Energy Prices Soar 338

An anonymous reader writes: After the Fukushima meltdown, all of Japan's nuclear power plants were shut down, the last in late 2013. This week the government plans on starting up reactor No.1 at the Sendai nuclear power plant. Energy prices have risen 30% since 2011, and it is hoped that the plant will soon be producing a surplus of electricity. Not everyone is happy about the plant restarting. This weekend, about 2,000 protesters marched around the plant and voiced their opposition. "Past arguments that nuclear plants were safe and nuclear energy was cheap were all shown to be lies," said writer Satoshi Kamata, one of the demonstration organizers. "Kyushu Electric is not qualified to resume operations because it has not completed an anti-quake structure to oversee a possible accident as well as a venting facility."

What Will Happen When Cascadia Subduction Zone Slips 265

Noryungi writes: The New Yorker has published a chilling account of what would happen in the case of a major earthquake (roughly magnitude 9.0) inevitably striking the Cascadia subduction. "Under pressure from Juan de Fuca, the stuck edge of North America is bulging upward and compressing eastward, at the rate of, respectively, three to four millimetres and thirty to forty millimetres a year. It can do so for quite some time, because, as continent stuff goes, it is young, made of rock that is still relatively elastic. (Rocks, like us, get stiffer as they age.) But it cannot do so indefinitely." Most of the west coast of the U.S. and Canada is at risk, from Vancouver all the way down to Los Angeles and beyond. Most of the states and cities within this region are woefully under-prepared for a large earthquake. Scientists peg the odds at 1-in-3 for a quake within the next 50 years, and 1-in-10 for a really powerful one.

Humanitarian OpenStreetMap Team Responds In Nepal 25

An anonymous reader writes with news about the efforts of the The Humanitarian OpenStreetMap Team to help in the aftermath of the earthquake in Nepal. The team asks those living in the affected areas to help out by reporting which buildings are damaged, which are still standing, and where fissures and other quake damage is located. has a profile of their efforts which reads: Since the devastating earthquake in Nepal, there have been responses from all over the world from relief agencies, governments, non-profits, and ordinary citizens. One interesting effort has been from the crowdsourced mapping community, especially on, a free and open web map of the world that anyone can edit (think the Wikipedia of maps.) The Humanitarian OpenStreetMap Team (HOT), an NGO that works to train, coordinate, and organize mapping on OpenStreetMap for humanitarian, disaster response, and economic development, has mobilized volunteers from around the world to help map since the Haiti earthquake in 2010.

Ham Radio Fills Communication Gaps In Nepal Rescue Effort 141

itwbennett writes: Amateur radio has stepped in to fill communication gaps in Nepal, which is struggling with power outages and a flaky Internet after a devastating earthquake on Saturday killed over 5,000 people. Though 99 persons have ham licenses in Kathmandu, about eight use high-frequency (HF) radios that can transmit long distances, while another 30 have very high frequency and ultra high frequency sets for local traffic, said Satish Kharel, a lawyer in Kathmandu, who uses the ham call signal 9N1AA. The hobbyist radio operators are working round-the-clock to help people get in touch with relatives, pass on information and alert about developing crises.

Nepal Earthquake: Facebook To Google, How Tech Is Helping Survivors Reach Out 39

An anonymous reader writes: In the aftermath of the earthquake that struck Nepal, many social media sites and mobile applications have come up with features that could help locate friends and loved ones. From the Times of India: "Social networking website Facebook, and Google's Person Finder have helped locate the whereabouts of those stranded in quake-hit areas. For instance, members of one Himmatramka family residing in Birgunj in Nepal marked themselves safe on Facebook. 'Our relatives back in India were worried about our safety. So, we marked ourselves safe to inform them,' said Nitesh Himmatramka.

7.8 Earthquake Rocks Nepal, Hundreds Dead 114

An anonymous reader writes: Nepal was struck by an earthquake of magnitude 7.8 today, with an epicenter 80 km east of the country's second biggest city, Pokhara. Its effects were also strongly felt in the capital, Kathmandu. Casualty reports conflict, but authorities have indicated at least 500 are dead and many more are feared to be trapped. Nepal has declared a state of emergency for the affected areas, and asked for international humanitarian assistance. India and Pakistan have both offered help. Some Indian cities were affected by the earthquake as well, and there are reports of avalanches on Mt. Everest, which has many climbers at any given time.

Fault System Enables Larger Quakes In California 63

Taco Cowboy writes Researchers have mapped the land at the southern end of the Hayward Fault and found that the creep continued 15 km beyond to merge with the Calaveras Fault, which was thought to be independent. "The maximum earthquake on a fault is proportional to its length, so by having the two directly connected, we can have a rupture propagating across from one to the other, making a larger quake," said lead researcher Estelle Chaussard, a postdoctoral fellow in the Berkeley Seismological Laboratory. "People have been looking for evidence of this for a long time, but only now do we have the data to prove it". The 70-kilometer-long Hayward Fault is already known as one of the most dangerous in the country because it runs through large population areas from its northern limit on San Pablo Bay at Richmond to its southern end south of Fremont. Last month the U.S. Geological Survey estimated a 14.3 percent likelihood of a magnitude 6.7 or greater earthquake on the Hayward Fault in the next 30 years, and a 7.4 percent chance on the Calaveras Fault, but there is one problem — the estimate was based on the assumption that the two faults are independent systems, and that the maximum quake on the Hayward Fault would be between magnitudes 6.9 and 7.0. Given that the Hayward and Calaveras faults are connected, the energy released in a simultaneous rupture could be 2.5 times greater, or a magnitude 7.3 quake.

Developers Race To Develop VR Headsets That Won't Make Users Nauseous 164 writes Nick Wingfield reports at the NYT that for the last couple of years, the companies building virtual reality headsets have begged the public for patience as they strive to create virtual environments that don't make people physically sick. "We're going to hang ourselves out there and be judged," says John Carmack, chief technology officer of Oculus, describing what he calls a "nightmare scenario" that has worried him and other Oculus executives. "People like the demo, they take it home, and they start throwing up," says Carmack. "The fear is if a really bad V.R. product comes out, it could send the industry back to the '90s." In that era, virtual reality headsets flopped, disappointing investors and consumers. "It left a huge, smoking crater in the landscape," says Carmack, who is considered an important game designer for his work on Doom and Quake. "We've had people afraid to touch V.R. for 20 years." This time around, the backing for virtual reality is of a different magnitude. Facebook paid $2 billion last year to acquire Oculus. Microsoft is developing its own headset, HoloLens, that mixes elements of virtual reality with augmented reality, a different medium that overlays virtual images on a view of the real world. Google has invested more than $500 million in Magic Leap, a company developing an augmented reality headset. "The challenge is there is so much expectation and anticipation that that could fall away quite quickly if you don't get the type of traction you had hoped," says Neil Young. (More, below.)

How a Shaking Stadium Is Helping Scientists Track Earthquakes 25

vinces99 writes Researchers are installing three seismometers in Seattle's CenturyLink stadium to monitor shaking from Seahawks fans during Saturday's NFL playoff game. The new, faster data transmission will show crowd motion on the website before a touchdown shows up on the 10-second delayed TV broadcast. Researchers dub these "Early Earthquake Rowdiness Warnings." A guaranteed shaking and intense public interest gives the seismologists a unique opportunity to test new technology that gives seconds to minutes warning of a real earthquake.

Quake On an Oscilloscope 71

An anonymous reader writes: Developer Pekka Väänänen has posted a fascinating report on how he got Quake running on an oscilloscope (video link). Obviously, the graphic details gets stripped down to basic lines, but even then, you need to cull any useless or unseen geometry to make things run smoothly. He says, "To cull the duplicates a std::unordered_set of the C++ standard library is used. The indices of the triangle edges are saved in pairs, packed in a single uint64_t, the lower index being first. The set is cleared between each object, so the same line could still be drawn twice or more if the same vertices are stored in different meshes. Before saving a line for end-of-the-frame-submit, its indices in the mesh are checked against the set, and discarded if already saved this frame. At the end of each frame all saved lines are checked against the depth buffer of the rendered scene. If a line lies completely behind the depth buffer, it can be safely discarded because it shouldn't be visible."

LA Mayor Proposes Earthquake Retrofits On Thousands of Buildings 178 writes The LA Times reports that Ls Angeles Mayor Eric Garcetti has proposed the most ambitious seismic safety regulations in California history that would require owners to retrofit thousands of buildings most at risk of collapse during a major earthquake. "The time for retrofit is now," says Garcetti, adding that the retrofits target buildings "that are known killers. Complacency risks lives. One thing we can't afford to do is wait." The mayor's plan calls for thousands of wood buildings to be retrofitted within five years, and hundreds of concrete buildings to be strengthened within 30. The retrofitting requirements must be approved by the City Council, and would have to be paid for by the building owners, with the costs presumably passed on to tenants and renters. The costs could be significant: $5,000 per unit in vulnerable wooden buildings and $15 per square foot for office buildings, Business owners, who have expressed concern in the past that these kinds of programs may be unaffordable, said the cost of retrofitting some buildings could easily exceed $1 million each. "This will cost us billions of dollars in the private and public sector," says Garcetti. "But we cannot afford not to do it."

The last major earthquake in Los Angeles was the 6.7-magnitude Northridge quake, which killed close to 60 people in 1994. But it was not close to the catastrophe that seismologists predict if there is a major shift on the San Andreas fault, and the fact that it has not produced a major quake in recent years has fed a sense of complacency. Seismologists now say a 7.5-magnitude event on the Puente Hills would be "the quake from hell" because it runs right under downtown Los Angeles and have estimated that would kill up to 18,000 people, make several million homeless, and cause up to $250 billion in damage. "We want to keep the city up and running after the earthquake happens," says Lucy Jones aka "The Earthquake Lady," a seismologist with the United States Geological Survey and something of a celebrity in a city that is very aware of the potential danger of its location. "If everything in this report is enacted, I believe that L.A. will not just survive the next earthquake, but will be able to recover quickly."

Nevada Earthquake Swarm Increases Chance of Larger Quake 65

An anonymous reader writes Hundreds of small earthquakes have been gaining in strength in northwestern Nevada. The Nevada region bordering California and Oregon was hit by 18 quakes in less than 24 hours, with magnitudes measuring from 2.7 to 4.5. According to CNN: "This does not necessarily mean a big one will come, state seismologists said, but they added that it's good to be prepared, just in case. Seismologists refer to such quake groupings as swarms, and the U.S. Geological Survey has detected them regularly. They can produce thousands of small tremors."

John Romero On Reinventing the Shooter 266

An anonymous reader writes: John Romero helped bring us Doom, Quake, and Wolfenstein, but he's also known for Daikatana — an immensely-hyped followup that flopped hard. After remaining on the periphery of game development since then, Romero announced last month that he's coming back to the FPS genre with a new game in development. Today, he spoke with Develop Magazine about his thoughts on the future of shooters. Many players worry that the genre is stagnant, but Romero disagrees that this has to be the case. "Shooters have so many places to go, but people just copy the same thing over and over because they're afraid to try something new. We've barely scratched the surface."

He also thinks the technology underpinning games matters less than ever. Romero says high poly counts and new shaders are a distraction from what's important: good game design. "Look at Minecraft – it's unbelievable that it was made by one person, right? And it shows there's plenty of room for something that will innovate and change the whole industry. If some brilliant designers take the lessons of Minecraft, take the idea of creation and playing with an environment, and try to work out what the next version of that is, and then if other people start refining that, it'll take Minecraft to an area where it will become a real genre, the creation game genre."

Changing the Rules of a 15-Year-Old Game: Quake Live Update Causes Controversy 170

An anonymous reader writes: As id Software aims for a larger, more mainstream audience for its free-to-play shooter Quake Live (based on 1998's Quake III Arena) on Steam, big changes are afoot. A new update was pushed out last week which adds some new, more beginner-friendly features to the game. These include weapon loadouts, which grant players a weapon of their choice when they spawn, timer icons, which indicate when the all-important powerup items will spawn, and an automatic bunny-hop to gain extra speed. The changes have been met with hostility from longtime players who prefer the "purist" rules of old and the duel format. As the writer points out, however, if the update helps attract more elite players to the gamer, it could breathe new life into a very old game.

Magnitude 6.0 Quake Hits Northern California, Causing Injuries and Outages 135

As numerous sources report, an earthquake of magnitude 6.0 struck California early Sunday morning, with an epicenter about 9 miles south of Napa. According to the San Francisco Chronicle's account, Some power lines down in western Contra Costa County, but Bay Area bridges appeared to be fine, according to the California Highway Patrol. There were widespread reports of power outages, gas leaks and flooding in the North Bay, with at least 15,000 Pacific Gas and Electric Co. customers without power in Vallejo, Napa, Rohnert Park, Santa Rosa and Sonoma. Police reminded motorists to stop at darkened intersections. ... In Benicia, several miles from the epicenter, the quake was strong enough to knock pictures off mantles. Bay Area bridges appear to have survived the quake -- significant, in that the L.A. Times reports that USGS estimates peg it as "the largest earthquake to strike the Bay Area since the Loma Prieta temblor of 1989," and says that injury reports (especially from glass) are streaming in from the area around Napa. The Times also has a larger estimate of customers suffering power outages: "more than 42,000" around the northern Bay Area. Unsurprisingly, social media channels are full of pictures showing some of the damage.

For those in California, did you feel the quake? (And from how far away?) Update: 08/24 13:15 GMT by T : Also in earthquake news: an even stronger quake (magnitude 6.4) on Saturday struck central Chile, shaking Santiago -- nearly 70 miles from the epicenter -- for more than half a minute, but with "no immediate reports of fatalities or serious damage."
