The USGS warning system that knows when rumbling volcanoes will blow their mountain tops
The National Volcano Early Warning and Monitoring System is standardizing and modernizing the nation's hodgepodge of USGS and academic volcano monitoring stations.
Modified drones help scientists better predict volcanic eruptions
With the help of drones, we could predict when the next major eruption could happen.
Hitting the Books: Volcanoes, mortal enemy of the mighty telescope
In The Last Stargazers: The Enduring Story of Astronomy's Vanishing Explorers, author Emily Levesque shines a light on today’s astronomers, a hearty breed of scientist willing to endure uncomfortable work conditions, odd hours, and some of the most remote sites on the planet for a chance to unlock the secrets of the cosmos. In the excerpt below, Levesque recalls the time a volcanic eruption in Washington state derailed a sky survey in Hawaii and led to one of the most epic log entries in scientific history. Telescopes actually have something of an interesting quirk when it comes to these tremors: they’re pointed so incredibly carefully and kept so incredibly still that even the tiniest and earliest shake of an earthquake can show up dramatically in the view of the telescope.

The drama and fury of Kilauea's volcano from space
Hawaii's Kilauea Volcano is causing all kinds of havoc. So far, it's wiped out at least 600 homes including a neighborhood called "Vacationland," completely filled in Kapoho Bay and rained olivine gems from the sky. Now, its destruction has been caught by the ESA Copernicus satellite Sentinel-2B (in visible and infrared light) with some dramatic enhancements from photo and geography enthusiast Pierre Markuse.
The gear you need to celebrate 4/20 like a responsible adult
It's 4/20 everybody, the High Stoner Holiday where we burn our trees rather than decorate them! The celebrations mark a magical moment when everybody can get the giggles with reckless abandon while satiating their munchies with traditional holiday tidings like Abba-zabba and Taco Bell. Today offers neophyte cannabis enthusiasts and hardcore stoners alike an opportunity to indulge in the mild euphoric of their choice with like-minded friends and family, or really, anybody standing with a dutchie on their right-hand side. But just as Christmas suffers from SantaCon, 4/20 celebrations attract their own brand of red-eyed knuckleheads who make the rest of us look bad. So unless you want to get lumped in with the folks who still proudly display their Scarface poster from college, put down that comically large blunt and read on.
Catching lightning in a volcanic bottle
What do you get when you marry two of Earth's most dramatic natural events, lightning and volcanoes? The answer is a "dirty storm," an infernal melange of lightning, magmatic fire and ash that surpasses even the wildest Hollywood disaster movie effects. If the volcano has enough energy, dozens of bolts -- which blast upwards, rather than downwards -- can spawn in the ash. At the Volcán Calbuco in Chile, photographer Francisco Negroni captured a stunning example of the phenomenon, winning second prize at this year's Epson Pano awards.
Study finds massive volcano range hidden in Antarctica's ice
A new study claims to have found a huge expanse of volcanoes lurking beneath the ice in Antarctica. Scientists unearthed a total of 91 previously undiscovered volcanoes -- some stretching up to 3,850 metres (12,600 feet) in height -- in the region known as the West Antarctic Rift System (WARS). The area is comparable to the densely concentrated volcanic regions in east Africa and North America, according to researchers from the University of Edinburgh.
Satellites may predict when a volcanic eruption will end
We've discussed how satellites are being used to research natural disasters, including monitoring the Earth's movement to predict landslides. Now, scientists have begun using satellite data to predict when volcanic eruptions' lava flow will end.
NASA AI auto-captured the changes in famous Ethiopian volcano
Artificial intelligence can help satellites and other spacecraft observe interesting phenomena before humans even spot them. Case in point: NASA's Earth Observing 1 (EO-1) spacecraft started capturing images of Ethiopia's Erta Ale volcano as soon as it developed a new fissure in late January. Volcanologists are keeping a close eye on Erta Ale, since it's one of the handful of volcanoes with lava lakes at the summit. They sent in requests asking NASA to use its Earth Observing-1 satellite to snap photos of the eruption, but by that time, the images were already available.
Stare into an active volcano with Google Street View
Standing next to a boiling lake of molten rock the size of two football fields has got to be awe-inspiring, but it's also pretty damn dangerous. Google partnered with two explorers to capture images of one such volcano as they rappelled down the walls of the Marum crater on Ambrym, an island a thousand miles off the coast of Australia. The team carried a Street View camera during their journey to let you see this natural wonder with Google Maps.
Mars may have had explosive volcanoes
The prevailing wisdom is that Mars has long been a stable planet. Without tectonic plates, it didn't have the violent upheavals that lead to earthquakes and explosive volcanoes here on Earth... did it? Not so fast. Scientists combing over data from NASA's Curiosity rover have found evidence suggesting that explosive volcanoes were a reality in the past. Samples from the planet's Gale crater include high concentrations of the mineral tridymite, which you tend to see around explosive volcanoes here on Earth. If so, the material was most likely carried from volcanoes to the crater by ancient water streams.
First 3D map of Earth's interior shows where volcanoes come from
It's no secret that Earth's volcanoes are the result of magma rising through the planet's mantle, but have you wondered just where those 'roots' run? UC Berkeley can provide an answer. It just created the first-ever detailed 3D map of the Earth's interior by studying the path of seismic waves. The model shows mantle plumes (where the hot rock flows) starting at the bottom of the core-to-mantle boundary and climbing to the top, where they connect to volcanic hotspots in the Earth's crust. As it turns out, the plumes don't take a straight path -- they often spread out as they merge with the colder upper mantle. It's also clear that most of the world's volcanoes (such as those in the Pacific's island chains) ultimately come from two large "blobs" of hot rock at the core boundary.

Controlling a jetpack is looking easier and easier, and I don't care if flight only lasts 30 seconds y'all, this stuff is happening! And Nike unveiled a new line of shoes for people with disabilities and it's the best use case for a non-gym basketball shoe that we've ever seen. Good job guys.
Watch a brave drone get dramatically close to an erupting volcano
DJI has just shown off one of the most spectacular drone videos we've ever seen of an erupting volcano, so close it resulted in a melted a GoPro camera. The pilot, Eric Cheng, captured the footage at the Bardabunga volcanic system in Iceland using an off-the-shelf DJI Phantom 2 drone equipped with a GoPro Hero 3+ camera. After an eleven hour journey over nearly impassable terrain, his team arrived to within 2 km of the volcano, which was spewing lava as high as 150m (460 feet) in the air.
Spiritual Guidance: Top 10 trinkets for the pre-raiding shadow priest
Every week, WoW Insider brings you Spiritual Guidance for discipline, holy and shadow priests. All armor is pretty much the same. That may have always been the case, when it comes down to it, but it seems especially noticable in Cataclysm. Each armor slot has the same "stat budget," with the only differences between pieces of equipment at the same item level being the secondary stats that piece contains. Thanks to reforging, finding the right piece of armor isn't a big deal -- we can just find something close to what we need and modify it until it meets our specifications. Our two trinket slots are special, though. Trinkets don't carry around the same intellect and stamina that all other equipped pieces of armor do. It's notoriously difficult to rank which trinket is best, because they all have special "on-use" or "proc" effects that vary from piece to piece. Of course, it's those differences that make trinkets so compelling. The right trinket can make a huge impact in your DPS. For those of you who have yet to raid, there are 10 solid DPS caster trinket options -- six ilevel 346 rares and four ilevel 359 epics -- that you can choose from if you have the patience (or gold). Most have a huge spellpower proc. Some offer haste. One special little trinket offers intellect. We'll break them all down in this week's quest to answer the question, "What trinket is right for me?"
Inhabitat's Week in Green: fly like a bird, bend batteries in half, and spray clothing from a can
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. This week saw several amazing feats of aeronautics as we showcased the world's first continuous flight of a human-powered ornithopter and the sun-powered Solar Impulse plane embarked upon an incredible voyage across Switzerland. We also watched transportation take off as BMW unveiled a zippy new electric scooter, Sanitov launched a GPS enabled cargo tricycle in London, and this week's Green Overdrive show took us off-roading on a souped-up e-bike! Renewable energy tech also energized the globe as several countries in Central America launched plans to tap volcanoes for power and China developed the world's first directly solar-powered air conditioning unit. Energy storage also got a big boost as Stanford researchers unveiled a new type of bendable battery made out of paper - just the thing to power the flexible e-readers of the future. In other news, this week we brought you exclusive coverage of the greatest green designs from this year's London Design Festival and we showcased the latest in wearable tech - instant spray-on clothing in a can! Finally, we tackled an issue that has plagued tech junkies forever - those impossible-to-open clamshell plastic packages.
Silicon carbide sensors developed for transmitting inside volcanos
There's one serious obstacle to volcano research: volcanos, like, shoot lava. Sure, you could aim a thermal camera at one from a safe distance, but where's the fun in that? On the other hand, researchers at Newcastle University are developing silicon carbide-based components for a device that they say will be able to withstand 900° Celsius temperatures -- just the thing to sense what's going on inside a volcano and transmit the info in real-time. Not only will this allow researchers to better understand conditions leading up to an eruption, it might also someday signal an eruption before it occurs. "At the moment we have no way of accurately monitoring the situation inside a volcano," says NU's Dr. Alton Horsfall. "With an estimated 500 million people living in the shadow of a volcano this is clearly not ideal." Since silicon carbide is more resistant to radiation than plain ol' silicon, the tech can also be used inside nuclear power plants or even as radiation sniffers in places that might face a terror attack.
Monsoon Vulkano do-it-all media box starts shipping, gets unboxed
Looking for one box to rule them all? If so, you must have glossed right over Monsoon's Vulkano launch, but lucky for you, there's a reminder coming in the form of a 'now shipping' proclamation. Just weeks after the $379 mega-box -- which aims to replace all of those other STBs under your television -- went up for pre-order, the earliest of adopters have started to receive their devices. We're still waiting on a proper critique, but if you're yearning to have a glance at what the future of media looks like, give those links below a look. Just kidding about that last part, by the way. [Thanks, Dan]
Power Gig throws fake guitars into volcano, dooms mankind
Hey, Seven45 Studios? We need to have some words about your recent viral advertisement for Power Gig: Rise of the SixString, which is posted just after the jump. Provided the footage therein is real -- and in this day and age of fancy-schmancy video editing software, who really knows -- then we're terrified for the future of Iceland. After all, we think we can all agree that what the April eruptions of Eyjafjallajökull were missing were ballistic, Skittle-colored shards of molten plastic. Check out the edgy (and quite possibly felonious) ad just past the jump.
Monsoon Vulkano all-in-one DVR/placeshifting/media streaming box ready for preorder, ships August 10
Monsoon -- after taking advantage of a few delays since our initial hands-on by adjusting the name and pricing -- is finally ready to show off the followup to its HAVA line of placeshifting media streamers, the Vulkano. Integrating a video processor and local storage into its slim frame, the Vulkano accepts HD video over its analog inputs for recording and live streaming to other devices (PC, Mac, iPhone/iPad, Blackberry and Android players will be available at launch, with a Symbian version on the way) or it can convert recordings locally for them to be downloaded over WiFi or 3G and stored on those devices for offline viewing. Remote scheduling and channel changing functionality (controlling connected set-top boxes via IR blaster) isn't a shocking new feature, but this goes a step further by bringing internet videos to your TV (YouTube, local UPnP devices) Boxee and Popbox style, and other big names like Hulu, Netflix, Google TV, Amazon Yahoo! Widgets and a full HTML browser are promised to show up in firmware updates soon. Believers can hit the site to preorder now, with units ranging from the $279 Vulkano with 8GB of SD card storage, up to a $379 Vulkano Pro with 1TB eSATA HDD included and other sizes planned in between.
