Comments Off on Kilauea’s crater has been dramatically altered by eruption

While Hawaii ‘s Kilauea volcano continues to erupt, this explosive episode of volcanic activity has already made a dramatic impact on the land, from the summit down to the ocean . Prior to the eruption, the crater summit presented as a massive lava pool. With the start of the eruption and the opening of fissures in early May, the lava drained from the crater toward lower ground. The subsequent explosions of ash and gas caused the crater to begin to collapse. Now, weeks later, the crater has become a steep, gray depression with a depth of 1,000 feet from the rim to its deepest point.   As the volcanic activity continues, so too does the deepening of the crater . The U.S. Geological Survey recently reported that the location of a GPS station within the crater dropped 200 feet within a week. Satellite images have helped to illustrate the speed and intensity with which the crater summit has deformed. “The fringes are so close together in the center of the caldera that they merge together and cannot be distinguished — a sign of the extreme and rapid style of subsidence happening at the summit!” wrote the USGS . Related: Kilauea lava boils away Hawaii’s largest freshwater lake in just a few hours While the images may be striking, Kilauea’s evolution is very much in line with what scientists expect to occur in the wake of an eruption and the subsequent draining of molten rock. “If you look at a lot of these big shield volcanoes, these collapse calderas are fairly common features,” Denison University volcanologist Erik Klemetti told Earther . Though such a crumbling of the caldera was anticipated, the ultimate conclusion of this eruptive event is yet to be determined. “I think it’s anybody’s guess,” Klemetti said. Meanwhile, the lava flow from the volcano is now more fluid and hotter than it was previously, posing a new, fast-moving danger to those in the region. Via Earther Images via USGS

Comments Off on New evidence shows humans survived massive volcanic eruption 74,000 years ago

In a newly published study , scientists reveal evidence that groups of humans survived a massive volcanic eruption at the Toba caldera, a supervolcano in Sumatra. “It is possible that people moved out of terrestrial locations and into this more productive coastal zone,” study co-author Curtis Marean told Inverse . “Think of it as a refuge.” Inland wildlife, plants and fungus faced a greater disruptive impact than those located closer to the coast, a key fact that enabled savvy human communities to survive the decade-long volcanic winter and endure the centuries-long consequences of the massive volcanic eruption 74,000 years ago. The Toba eruption was so powerful that shards of tephra, the rock debris projected from a volcanic event, managed to reach as far as South Africa , nearly 5,600 miles from the Toba caldera. “Glass shards are a form of tephra that preserve a record of the chemical composition of the lava erupted during the eruption. The shapes and sizes of the shards also provide information about the nature of the eruption,” study author  Gene Smith told Inverse . “We can tell quite a bit about a volcanic eruption by studying products ejected from the volcano.” Related: Wave of earthquakes shake Yellowstone’s super-volcano The researchers observed that the global impact of the Toba eruption encouraged communities to move to coastal areas, which were less affected by the eruption. The flexibility and attentiveness of these early human communities is worth noting, as modern society may not be quite as dynamic in the face of such an event. “Hunter-gatherer economies are very resilient, but I don’t think the complex modern economies are,” said Smith. “A Toba-like event is a civilization killer for us. Perhaps our study will waken people up to the potential of volcanic catastrophe.” Via Inverse Images via Depositphotos ,  Smith et al. and  Dr. Jayne Wilkins

Most active volcano in the Philippines sends locals and tourists fleeing

Comments Off on Most active volcano in the Philippines sends locals and tourists fleeing

Mount Mayon, the most active volcano in the Philippines , sent lava billowing down its slopes on Tuesday and prompted an evacuation of more than 21,000 locals who live in threatened areas. According to the Philippine Institute of Volcanology and Seismology, lava flowed as far as 1.2 miles from the crater while ash from the volcanic activity spread to several communities in the northeastern Albay Province, where Mayon is located. Although the sight of an active volcano is breathtaking, authorities have advised that people remain beyond the 3.7-4.3 mile danger zone around Mayon. “They say it’s beauty juxtaposed with danger,” Office of Civil Defense regional director Claudio Yucot said, according to CBS News . Of the at least 21,800 people to be displaced by Mayon’s most recent eruptive episode, over 16,800 have taken shelter in 22 schools throughout the region. Others found safety at the homes of relatives far from the danger zone. Locals have expressed concern for their livestocks, which authorities have met by setting up evacuation areas for animals such as pigs, poultry, water buffalo, and cattle.  Despite the vivid display of danger, the volcano’s current lava spell was sparked by lava fragments splitting from the lava flow, not from an explosive eruption from within the crater. Further, scientists have not observed the level of volcanic earthquakes that would indicate an imminent eruption. If such an eruption were to appear imminent, authorities say that they are ready for a large-scale evacuation operation. Related: Scientists construct new theory of Yellowstone’s supervolcano hotspot Mayon has erupted about 50 times in the past 500 years, often with great strength. Its first recorded eruption was in 1616 while the most destructive occurred in 1814, when 1,200 people were killed and the town of Cagsawa was buried. The most recent episode before the current occurred in 2013 when an eruption of ash killed five people who attempted to climb the volcano despite warnings. While Mount Mayon may be the most active, it certainly is not the only volcano in the Philippines. Mayon is a part of the Ring of Fire, an area in the Pacific in which seismic faults are plentiful and often produce earthquakes and volcanic activity.

NASA considers puncturing Yellowstone supervolcano to save life on Earth

Comments Off on NASA considers puncturing Yellowstone supervolcano to save life on Earth

A new study from NASA’s Jet Propulsion unit has determined that the threat of a supervolcanic eruption to life on Earth may be more pressing than any interstellar collisions. An eruption of a supervolcano, like that found in Yellowstone National Park in the United States, could trigger a collapse of the global agricultural and economic systems and result in the deaths of potentially millions of people. Although NASA scientists can’t predict when such an event would occur, they have already begun preparing a preventative measure: drilling into the magma chamber of a supervolcano to cool it down. Although the potential consequences of a supervolcano eruption would be devastating, earthlings should rest easy knowing that the chance of such an eruption taking place this year is roughly 1-in-730,000. Even then, there is a chance that it could be nothing more than a little lava flow. Nonetheless, NASA scientists are preparing to deal with the problem before it happens. Related: World’s most active volcano harbors a tiny off-grid home—and you can stay overnight Magma eruptions occur only when it is thoroughly melted by intense heat; cooling magma down by 35 percent would prevent a supervolcano from erupting. To do this, the scientists envision using a drill to puncture above the chamber, where hydrothermal fluids are pushed to the surface. Adding water in this highly pressurized environment would be sufficient to cool the magma. To avoid fracturing the surrounding rock and potentially setting off an eruption, NASA scientists suggest drilling into the supervolcano from below. It is estimated that such a plan would cost around $3.5 billion, although governments would be encouraged to think of this as an investment : Excess heat could be captured and transformed into clean energy .

Comments Off on True North Detroit is an affordable live-work community made from prefab Quonset huts

A number of grassroots initiatives and organizations are revitalizing Detroit as a testing ground for urban innovation. Edwin Chan and his Los Angeles–based design practice EC3 recognized the potential of the city’s underutilized community spaces and recently completed True North Detroit , a half-acre live-work community made from lightweight prefabricated Quonset huts. This small complex of nine vaulted buildings offers affordable housing for Detroit’s growing creative population. Located in the Core City neighborhood, about two and a half miles northwest of downtown, the community breathes new life into an area that consists mostly of vacant lots. Related: America’s first urban ‘agrihood’ feeds 2,000 households for free “The majority of Detroit’s housing stock is either out of date or completely dilapidated,” Edwin Chan said. “Rather than being determined by ‘market demands,’ True North’s design is an inclusive and aspirational vision to create a new typology of affordable housing and to promote alternative, creative lifestyles in one of the world’s most iconic cities.” Related: These tiny houses help minimum wage workers become homeowners in Detroit The architects modified the original shape of the Quonset huts to create more elongated, higher spaces ideal for a variety of activities. The center island houses the kitchens, bathrooms, and utilities. This space is built from durable polycarbonate , while the rest of the structure has a more transparent envelope that allows natural light into the interior. Affordable materials and building methods were used in the construction of the apartments, which range from 475 to 1,600 square feet. + Edwin Chan + True North Detroit Via Archpaper

Comments Off on People are using recycled laptop batteries to power their homes

Why spend thousands of dollars on a Tesla Powerwall when you could build your own – for a fraction of the cost? This is a question many alternative energy enthusiasts have asked, and it is ultimately what has led hundreds of people to develop their own versions using recycled laptop batteries. Now that plans for DIY Powerwalls are being shared for free online, several people have created rigs capable of storing far more energy than the Tesla version. On Facebook , YouTube and in forums , people are learning how to safely create their own DIY versions that cost much less than a Tesla Powerwall. One of the most popular powerwall builders is Jehu Garcia . He told Vice, “It’s the future. It’s clean, simple, efficient and powerful.” Joe Williams , another DIY powerwall enthusiast, added ”The end result is being able to rely on something I not only built myself but understand the ins and outs of to power some or all of my electricity in my home. That is inspiring.” There are several DIY versions capable of storing more energy than Tesla’s Powerwall. On the French forum  Diypowerwalls.com , user Glubux said his powerwall can store 28 kWh of energy. “I run all the house with it, in fact I even bought an electric oven and induction cooking plate to use the extra energy during summer,” they said. Australian YouTuber Peter Matthews claims he has created a gigantic battery that can store 40 kWh of energy. Reportedly, it harvests power from over 40 solar panels on Matthews’ roof and stores nearly enough power for his home’s electricity needs. “The only things I don’t run are the big air conditioners and the water heating system,” he said. The alternative energy aficionado created DIYpowerwalls as well as the most popular powerwall Facebook group . Related: Mercedes takes on the Tesla Powerwall with a new battery for buildings Most of the powerwall hobbyists recommend using 18650 lithium-ion batteries for their projects. The batteries are usually encased in a colorful plastic and can be found inside electronics, such as laptops. If sourced online or from a computer store, the batteries will cost more than $5 a piece. If obtained second-hand, from old Dell, HP, Lenovo and LG laptops, it’s possible to save hundreds — if not thousands — of dollars on the project. Of course, one might meet challenges collecting the batteries , as tech companies frown upon their creative repurposing. A positive effect of the DIY powerwall trend is that it reduces waste . According to Carl E. Smith, the CEO and president of  Call2Recycle , approximately 95 percent of consumer batteries which are sold in the US are not recycled and are ultimately thrown away. ”Virtually all batteries can be recycled into valuable secondary products which is the biggest reason why they should not be landfilled and should be recycled instead,” he said. Though it can be time-consuming to source the used batteries, it’s a worthwhile investment according to DIY powerwall enthusiasts. And, if one carefully follows instructions when building their own version (such as those that follow), the risk of burning down one’s house is minimized. Ultimately, there is a risk associated with creating your own energy storage device, but the trend can’t be ignored as it grows in popularity.
