Comments Off on Montana earthquake felt along line of over 500 miles

An earthquake that rocked Montana yesterday was felt by people across hundreds of miles. The 5.8 magnitude earthquake struck the western part of the state close to northwest Helena at 12:30 AM local time, but was felt by people in multiple states and even Canada. The quake was large enough to wake people up. The recent Montana earthquake was shallow but was felt by people across a line over 500-miles-long from around Billings to Spokane, Washington. There weren’t any reports of injuries, according to Montana Public Radio, but people over a widespread area were awakened by the shaking. The earthquake was the strongest Montana has experienced in possibly over a decade – according to NPR a 5.6 magnitude earthquake struck in 2005.

The United States Geological Survey (USGS) said the earthquake “occurred as the result of shallow strike slip faulting along either a right-lateral, near vertical fault trending east-southeast, or on a left-lateral vertical fault striking north-northeast.” The earthquake hit around 230 miles away from Yellowstone National Park , and as it was felt over such a wide area some people wondered if the Yellowstone supervolcano had become active. But the park service said the area typically has over 1,000 earthquakes yearly, and experts have said it is very unlikely a large eruption will occur in the next 1,000 to 10,000 years. The earthquake may not have stemmed from the supervolcano but still rattled residents out of the routine of their daily lives. Volunteers pitched in to help clean up a local grocery store in Lincoln, the D&D Foodtown, which lost pickle jars and wine bottles – but assistant manager Ruth Baker said all of the eggs in the store survived.

Comments Off on China breaks ground on 12-mile treetop walkway in Fuzhou forest

China’s magnificent new walkway is giving people a treetop experience of Fuzhou’s sub-tropical forests unlike any before. Singapore-based LOOK Architects recently completed the first phase of the Fuzhou Forest Walkway, a snaking treetop walkway that will span over 19 kilometers (nearly 12 miles) at completion. The elevated pedestrian pathway looks like a dragon’s back threading down the lush Jinniushan mountain and offers urban dwellers the chance to reconnect with nature and brings attention to one of the city’s quickly diminishing green lungs. Covered in greenery thanks to a sub-tropical climate, Fujian’s capital of Fuzhou is one of China’s greenest cities and is famous for its numerous banyan trees that line the streets. LOOK Architects’ Fuzhou Forest Walkway brings nature closer to the city with an elevated path that covers the full breadth of Jinniushan mountain and offers beautiful views of the canopy , the city, and mountains beyond. The architects described the project as “a signature urban connector network that provides public accessibility to indigenous hinterland stretching north- east of Minjiang. Fudao signifies an awakened consciousness to improve lives of city dwellers by bringing nature within closer reach.” The project also presented the opportunity to open up and redevelop many parts of Jinniushan that had been inaccessible to the general public due to proximity to military camps and burial sites. The new enhancements included a modern columbarium complex constructed to rehouse exhumed graves, the adaptive reuse of an abandoned quarry into a new visitor’s center, and the transformation of an old bus depot Xikezhan into the main entrance that doubles as a food and beverage enclave. The walkway can be accessed via 10 different entrances, each with unique and eye-catching features such as the grand 24-meter-wide spiral ramp at the entrance of the existing Jinniushan indoor sports hall. Built with a gentle gradient, the elevated walkway is punctuated with amenities that include rest shelters, viewing decks, observation towers, and teahouses with bathrooms. The structure is also equipped with WIFI connectivity, touch-screen information boards, and visitor traffic monitors, giving the project the potential to set a new bar for China’s eco-routes. Related: Spiraling treetop walkway gives visitors a bird’s eye view of a Danish forest Environmental conservation is a major priority of the project. The walkway is made up of eight modular components that can be combined in various permutations, each made up of steel grating to allow natural light to pass through.

Comments Off on Scientists discover Antarctica is covered in rivers

For decades, scientists have known that summertime brings liquid meltwater to Antarctica’s ice sheets. But until now, they’ve had no idea just how extensive the continent’s network of rivers, streams, ponds, and waterfalls really is. A new analysis by scientists at  Columbia University’s Lamont-Doherty Earth Observatory has found that warmer months cause far more extensive melting than previously thought. That could be a problem as global temperatures continue to rise. Surface water can damage the ice shelves , weakening them and causing them to collapse into the ocean. Some of the channels identified in this survey allow meltwater to run harmlessly off into the sea, but in other areas, standing water can be a huge problem. In 2002, more than 2,000 lakes on the Larsen B ice shelf drained through the ice into the ocean below, causing the entire area to rapidly disintegrate. Related: Scientists warn rapidly-melting glacier in West Antarctica could cause serious global havoc The presence of water on the frozen continent does not yet appear to be the cause of widespread problems—but there’s also the possibility that warmer temperatures are causing sub-surface ice melt. Unfortunately, that phenomenon has been researched in far less detail, so it’s unclear exactly what effect it will have on the ice and rising sea levels in the future.

Majority of Americans support Paris climate deal as Trump reconsiders pulling out

Comments Off on Majority of Americans support Paris climate deal as Trump reconsiders pulling out

A new survey shows strong bipartisan support in the US for staying in the Paris climate agreement that formally commits its 193 signatories to reducing greenhouse gas emissions to avert dangerous climate change. The Chicago Council on Global Affairs poll of 2,061 Americans finds that 71 percent agree that the US should participate in the pact, including a majority of Republicans (57 percent), Democrats (87 percent) and Independents (68 percent). President-elect Donald Trump has previously stated that he believes climate change is a hoax and that he intends to pull the US out of the Paris climate deal as soon as he takes office. However, in a potentially major reversal if he holds to it, Trump told New York Times reporters during a visit to the Midtown Manhattan newsroom that human activity is connected to climate change and that he would keep an open mind on the landmark climate accord. Related: Al Gore reaches out to work with Donald Trump on climate change On the link between human activities and climate change, Trump said that “I think there is some connectivity. Some, something. It depends on how much.” And when pressed on the Paris climate deal, Trump said that “I’m looking at it very closely. I have an open mind to it.” While this is a stunning reversal on his previous positions regarding man-made global warming, it remains to be seen whether Trump will change his policies that currently advocate for more oil, coal and natural gas at a time when many climate experts are warning that we have no carbon budget left and that we must keep remaining hydrocarbon reserves in the ground to sustain a livable climate. Trump’s new stance accepting human-induced climate change also goes against the climate deniers and fossil fuel industry insiders placed on his transition team and cabinet. The survey’s lead author Dina Smeltz, a senior fellow on public opinion and foreign policy at the Chicago Council, told The Washington Post that “an increasing percentage of Republicans now say that some gradual action should be taken” to address climate change concerns and that the American public “has been growing in their support for mitigating climate change.” + Chicago Council survey: Growing support in US for some climate action Via The Washington Post Lead image via Wikimedia , others via Wikimedia

Comments Off on 1.5 billion birds disappear from North Americas skies

A startling survey of North American skies reveals there are 1.5 billion less birds flying about than there were decades ago. Some species’ populations have recently become threatened , while others are projected to be nearly decimated within the next 40 years. An array of factors, mostly human-induced, are responsible for the alarming drop. “It’s the death of a thousand cuts,” stated the survey’s co-author Judith Kennedy, of Environment Canada. “We’re really getting down to the dregs of some of these populations.” Numerous government, environmental, and university-based agencies combined to conduct the most comprehensive, up-to-date Partners in Flight survey, which follows trends in continental bird populations . Related: 9 things you can do to help wild birds this summer 86 species of birds were classified as threatened by habitat loss, climate change , and plummeting population sizes. These include the Canada warbler and evening grosbeak, whose numbers have dropped 92 percent since 1970. Even the beloved snowy owl has experienced a 64 percent dip. Logging of forests, pesticides in grasslands, and an overabundance of cats – who kill an estimated 2 billion birds per year – all contribute to the downfall of the continent’s birds. Birds help human populations by gobbling up pesky insects and pollinating plants. Kennedy stresses the importance of making changes in our behaviors that affect native bird populations, stating, “It’s too late for us to worry when we’re down to the last few hundred.” Via The Star Images via Flickr , Wikipedia

USGS, EPA investigate link between underground wastewater disposal and Oklahoma’s largest earthquake

Comments Off on USGS, EPA investigate link between underground wastewater disposal and Oklahoma’s largest earthquake

On Saturday, a magnitude 5.6 earthquake shook north central Oklahoma , prompting the U.S. Geological Survey (USGS) to investigate whether the quake was caused by the oil and gas industry’s practice of underground wastewater disposal . The quake, which is reportedly the largest in the state’s history, damaged some buildings but there have been no reports of injuries or deaths. Many environmental scientists have long suspected that industrial activities like this are linked to, and can even cause, earthquakes, and hopefully soon the USGS will have answers about what is happening in Oklahoma. Saturday’s earthquake occurred near the city of Pawnee at 8:03 a.m. local time and was reportedly felt in six surrounding states. The quake was somewhat unusual because it occurred on a fault that seismologists didn’t even know existed. In fact, the fault that triggered the quake runs perpendicular to the larger well-known fault system. This is the key feature of the earthquake that piqued the interest of USGS researchers, who suspect that human activity may be partially responsible for kicking off the tremor. The Environmental Protection Agency is also investigating the causes and implications of the earthquake. Related: Surge of earthquakes in Oklahoma puts fracking under fire “Without studying the specifics of the wastewater injection and oil and gas production in this area, the USGS cannot currently conclude whether or not this particular earthquake was caused by industrial-related, human activities,” the USGS said in a statement. “However, we do know that many earthquakes in Oklahoma have been triggered by wastewater fluid injection.” State regulators at the Oklahoma Corporation Commission have ordered oil and gas operators to shut down 35 disposal wells that may have contributed to this weekend’s earthquake in what Governor Mary Fallin has called “a mandatory directive.” The wells located within five miles of a 10-mile section of the fault linked to the quake, and they have been ordered to shut down within seven days, and all the other wells must be shut down within 10 days. Last year, a series of earthquakes in Oklahoma had many scientists and environmentalists pointing fingers at fracking, the common practice in the oil and gas industry of injecting high-pressure liquids underground to open fissures, in an effort to gain access to oil and gas. As industry activity in the state has steadily grown, so too have the number of earthquakes measuring at least 3.0 on the Richter scale. After the  magnitude 5.1 quake between Tulsa and Oklahoma City in February, 2015 , residents feared that the worst was yet to come. With this weekend’s quake now being called the strongest ever in the state, and plenty of oil and gas industry drilling ongoing, nobody is sure at this point what to expect next.

Newly discovered ‘ghost galaxy’ full of dark matter is as big as the Milky Way

Comments Off on Newly discovered ‘ghost galaxy’ full of dark matter is as big as the Milky Way

Astronomers have discovered, with the aid of some powerful telescopes, a galaxy made up mostly of dark matter . Dragonfly 44, as it has been named, is roughly the same size as our Milky Way but with far fewer stars. Rather, the galaxy appears to be composed largely of dark matter, which does not emit light or interact with electromagnetic radiation. Although there is much more to learn about the mysterious dark galaxy, scientists’ initial findings have surprised astronomy experts more than once. Studies of Dragonfly 44 began with curiosity, as many deep space explorations do, after it was identified last year as little more than a smudge-like spot on an image of the Coma Cluster of galaxies captured by the Sloan Digital Sky Survey (above left). Right away, astronomers knew they had to investigate, and time-lapse images captured by the Gemini North telescope (above right) show the galaxy’s diffuse nature. “Very soon after its discovery, we realized this galaxy had to be more than meets the eye. It has so few stars that it would quickly be ripped apart unless something was holding it together,” Yale University astronomer Pieter van Dokkum, lead author of the study, told Phys.org. Related: Newly discovered dwarf galaxy may be falling into the Milky Way More powerful equipment was needed to get a better look, so the team turned to the W.M. Keck Observatory and the Gemini North telescope , in Hawaii, for help. Van Dokkum’s team was able to measure the velocity of stars in Dragonfly 44 by comparing images taken over six nights. Star velocity is a key element in gaining an understanding of the composition of a far-away galaxy, because it can help convey the galaxy’s mass. A higher velocity suggests a galaxy of higher mass. Knowing that the galaxy had very few stars (and thus not much light) but a mass closer to that of the Milky Way, researchers concluded that the newly discovered galaxy must be comprised mostly of dark matter . “Amazingly, the stars move at velocities that are far greater than expected for such a dim galaxy. It means that Dragonfly 44 has a huge amount of unseen mass,” said co-author Roberto Abraham of the University of Toronto. Further studies of Dragonfly 44 may help scientists finally come to an understanding of what dark matter actually is, which has eluded researchers since its existence was first suggested nearly a century ago. A paper on the initial study of Dragonfly 44 was recently published in the Astrophysical Journal Letters.

A swarm of earthquakes rattles central California

Comments Off on A swarm of earthquakes rattles central California

A series of small earthquakes rattled central California , beginning Sunday evening and continuing into Monday, but the U.S. Geological Survey (USGS) says there is no cause for alarm. The phenomenon, called an earthquake swarm, is actually fairly common in regions with a high level of geological activity (such as California). Despite the number of quakes—18 or more within a day’s time—the strongest registered a magnitude 3.7, which is not very strong as earthquakes go and no significant damage has been reported. With a sharp increase in earthquake activity, one might wonder whether bigger quakes are on the way. But USGS reports that swarms like this have not been connected to larger earthquakes occurring in the same region. The agency’s definition of an earthquake swarm, or seismic swarm , is actually fairly loose, referring simply to a cluster of small quakes happening in one area with no requirement for a set time period. The quakes don’t even have to occur along the same fault line to be considered part of the swarm. Related: Chance of California megaquake within next three decades increases The earthquake swarm in California may already be over, or additional tremors may still be on the horizon, but it’s unlikely they will lead to anything more substantial. Yellowstone National Park has seen a number of earthquake swarms over the years, with the largest happening in 2004, 2009, and 2010. That most recent swarm included more than 2,000 quakes over the course of a month. Although several registered a magnitude over 3.0, the swarm didn’t lead to any type of larger earthquake or other catastrophic event. Via Gizmodo Images via Shutterstock and  USGS
