1,000-foot-long fissure opens on Hawaii’s Kilauea as experts prepare for an explosive eruption

Two new fissures cracked open on Hawaii’s erupting Kilauea volcano over the weekend, and magma and rock burst into the air. Local Mark Clawson, who hadn’t evacuated, told Reuters , “It is a near-constant roar akin to a full-throttle 747 interspersed with deafening, earth-shattering explosions that hurl 100-pound lava bombs 100 feet into the air.” The eruptions have destroyed almost 40 buildings and one fissure threatens to disrupt a nearby geothermal plant. Meanwhile, the lava lake in Kilauea has been dropping, prompting experts to prepare for a possible explosive eruption. A new fissure that looks to be around 1,000 feet long is one of the biggest, Reuters said. Hawaii’s Civil Defense ordered more evacuations over the weekend as Kilauea continues erupting . Over 10 days, almost 2,000 people have been told to evacuate. The Hawaiian Volcano Observatory said in an update on Sunday evening local time the eruption “is still evolving and additional outbreaks of lava are possible.” They warned communities downslope of the fissures “could be at risk from lava inundation” and that “activity can change rapidly.” Related: Hawaii’s Kilauea volcano eruption has destroyed 26 homes and caused thousands to flee Toxic gases continue to spew as well; Reuters said trees withered and vegetation turned brown in places with strong sulfur dioxide emissions. All this prompted some officials to prepare residents for the possibility of an eruption. “We’ve got all the warning signs we need,” said Steve Brantley, deputy scientist-in-charge at the Hawaiian Volcano Observatory to the  Honolulu Star-Advertiser . “There may not be any additional warning before the magma actually starts moving up to the surface.” The Civil Defense told people living in lower Puna to be prepared to leave, and that “there may be little to no advance notice to evacuate.” Reuters quoted Major Jeff Hickman of the Hawaii National Guard as saying, “We’ve been telling them, ‘Evacuate if you can, because if we have to come in and get you we’ll be putting first responders at risk. There’s a point where we’ll tell our first responders, ‘Nope, you can’t go.’” While the fissures post a risk where they form, the real concern about eruption comes from the fact that the lava level has been dropping inside the volcano. If the volcano does erupt, it could send boulders the size of refrigerators into the air and plumes as high as 20,000 feet, with debris and ashfalls landing tens of miles downwind. The Washington Post reported the volcanic eruption doesn’t just threaten homes, but a geothermal plant residents have been concerned about for a long time. Lawsuits have targeted the Puna Geothermal Venture for its location on an active volcano . Authorities are worried over potential explosions or gas leaks because of Kilauea’s activity. Operations stopped on May 3 and workers removed potentially hazardous chemicals from the facility as a precaution. Via Reuters and The Washington Post Images via the U.S. Geological Survey

After 250 earthquakes in 24 hours, Hawaii’s Kilauea volcano might erupt

Comments Off on After 250 earthquakes in 24 hours, Hawaii’s Kilauea volcano might erupt

Out of the five volcanoes on Hawaii’s Big Island, Kilauea is the most active — and it’s threatening to erupt. After a collapse event at the Pu’u ‘?’? vent, in the volcano’s East Rift Zone, around 250 earthquakes happened. Authorities are warning people to remain on alert, because scientists observed magma flowing under a main road close to houses. Will Kilauea erupt? Seismic activity could result in a lava breakout, but Hawaiian Volcano Observatory scientists can’t say exactly what time or where it might happen. The crater collapse and earthquakes are “associated with the continued intrusion of magma into the East Rift Zone to locations east of Highway 130. An outbreak of lava from the lower East Rift Zone remains a possible outcome of the continued unrest,” according to the observatory. The Independent said there are homes in that part of the island, and Highway 130 leads to an access point enabling visitors to hike or cycle to a lava viewing area.

The Hawaii County Civil Defense Agency said areas that could be impacted are Leilani Estates, Nanawale Estates or Kapoho. The Hawaiian Volcano Observatory offered resources for those who want to stay updated about Kilauea ; sign up for notification emails from the Volcano Notification Service at this USGS website or sign up for the Civil Defense Emergency Notification System at the County of Hawaii website . The volcano’s activity hasn’t always been explosive in the past, but a 1924 eruption spewed ash and rocks into the air and killed one man. The summit crater gushed rock and lava across 75 acres in 2008, and a view point was damaged. + Hawaiian Volcano Observatory (1, 2) + County of Hawaii Via The Independent and CNN Images via Depositphotos and U.S. Geological Survey

Tesla’s Powerwall faces stiff competition from several other storage products

Comments Off on Tesla’s Powerwall faces stiff competition from several other storage products

While Tesla ‘s Powerwall may be the most well-known example of residential solar energy storage systems, it is not the only one and is facing increased competition. Nearly all major residential solar companies are now developing a similar household energy storage system, either independently or in collaboration with another company. Among those companies, SunRun, Vivint Solar and SunPower seem to be the most viable competitors to Tesla’s residential solar operations. The increased competition is good news for consumers as well as the renewable energy sector generally, indicating that the industry is maturing and spreading. SunRun now maintains the largest market share in the American residential solar industry , in part thanks to its ability to work with internal and external installation partners. This means that SunRun is able to more quickly scale up its distribution. The company’s Brightbox system incorporates LG Chem batteries into a control system (designed by SunRun) and is currently available in Arizona, California, Hawaii, New York, and Massachusetts , with more states coming online in 2018. Related: Nova Scotia Power pioneers new energy storage system using Tesla Powerpacks Vivint Solar is collaborating with Mercedes-Benz to develop a 2.5 kW-hr energy storage system that can be expanded up to a 20 kW-hr system for household needs. Mercedes-Benz already has energy storage products available in the more developed European market, which puts it in a good place as the American market grows. Last but not least, SunPower will launch its home energy storage system under its Equinox product line in 2018. Because they are geared towards high-end customers, those with the most funds to invest in new technology, it may see more rapid growth than its competitors. Regardless of the commercial success of any individual company, the flurry of activity in the American residential energy storage is a welcome sign as the United States, like the rest of the world, must move forward towards a clean energy economy.

Super blue blood moon eclipse to occur for the first time in 150 years

Comments Off on Super blue blood moon eclipse to occur for the first time in 150 years

On January 31, turn your eyes to the sky, because the moon is going to do something that it hasn’t done in a century and a half. On the last day of the month, lucky celestial viewers are going to witness a super blue blood moon eclipse. So what is a super blue blood moon eclipse? Let’s break it down. The supermoon is when the full moon is closest to the Earth, so it looks extremely bright and big. A blue moon is when the moon is full for a second time in a calendar month. Then, while all that is happening, there is going to be a total lunar eclipse . And as if that wasn’t enough, it’s also going to be a blood moon at the same time – something that occurs when blue light filters out of the atmosphere during an eclipse, making the moon appear red. Related: Missed the Blood Moon? Watch the Event Unfold Through NASA’s Stunning Footage In the U.S., the eclipse itself won’t be very visible except in Hawaii and Alaska. But viewers in New Zealand, Australia, parts of Asia, and Indonesia are in for a real treat. And in case you were wondering, the answer is no. The super blue blood moon eclipse doesn’t mean anything special, except that it is an exciting convergence of multiple interesting lunar phenomena. Via Phys.org Images via Deposit Photos ( 1 , 2 )
