USGS upgrades Aleutian volcano alert level: volcano stirring after 28 year slumber

March 2015 ALEUTIAN ISLANDS –  The USGS upgraded the island’s volcano alert level status to “advisory” and its aviation code to “yellow” Wednesday after an increase in seismic activity. Citing increased seismic intensity, the U.S. Geological Survey is upgrading the volcano alert level status for Semisopochnoi, an Aleutian Island volcano, to “advisory,” the US geological agency said in a notice issued Wednesday morning. Semisopochnoi Island or Unyak Island is part of the Rat Islands group in the western Aleutian Islands of Alaska. The island is uninhabited and provides an important nesting area for maritime birds. The island is of volcanic origin, containing several volcanoes including Mount Cerberus. It has a land area of 85.558 square miles (221.59 km2), measuring 18 kilometers (11 mi) in length and 20 kilometers (12 mi) in width.
Seismic activity at the Semisopochnoi volcano began in January, but “has increased in intensity over the past few days,” USGS wrote in the notice. “In addition, we have detected brief periods of seismic tremor, which can indicate movement of magma or magmatic gases.” Semisopochnoi is remote even by Alaska standards. It lies on an island of the same name some 127 miles from Adak and 1,283 miles from Anchorage. The volcano last erupted in 1987. –Alaska Dispatch News

Mudslide in Peru highlands kills at least 7, destroys homes

Peru Mudslide
March 2015 PERUA mud-heavy torrent has sent auto-sized rocks crashing into a highlands town along Peru’s main east-west highway and national civil defense chief Carlos Castro says it killed at least seven people and destroyed 65 homes. The central highway remained blocked by debris on Tuesday from the previous night’s catastrophe.
Boulders loosed by two hours of heavy rains smashed through brick walls and floodwaters carried cars, animals and furniture through Chosica’s streets. Televised images showed police breaking through the wall of one home to recover the bodies of 23-year-old Ana Marino and her 3-year-old son, Stefano. Mother was clutching child. Residents asked authorities to send heavy equipment to clear the wreckage. A 1987 mudslide in Chosica killed 64 people. Peru’s weather service predicts heavy coastal rains through the rest of March. –Yahoo News

Volcanoes in Chile and Mexico shaken by explosive ash eruptions

Chile Volcano
March 2015CHILE - A steady stream of smoke and ash leaking from the Villarrica volcano has residents of a nearby town wondering if – or when – disaster might strike. Chilean officials raised threat levels to orange on Wednesday due to increasing signs of activity in the 2840-meter tall volcano, leaving area residents fearful of an eruption. ‘No one can sleep peacefully because the other day the eruption surprised us at 3 in the morning,’ said Francisco Valenzuela, a tour guide in the nearby resort town of Pucon. Many of the residents in towns and communities surrounding the volcano had to be evacuated earlier in the month, when lava and smoke erupted from the peak in the early hours of the morning.
‘It was spewing lava and ash hundreds of meters into the air,’ 29-year-old Australian tourist Travis Armstrong said. ‘Lightning was striking down at the volcano from the ash cloud that formed from the eruption.’ Adding to the threat of ash and lava, the peak is covered by a glacier cap and snow, causing some officials to worry the eruption could cause mudslides or force rivers to flood and jump their banks. –Daily Mail
Mexico: The volcano continues to produce sometimes strong vulcanian-type explosions that seem to have picked up in strength over the past days. An eruption at 03:08 am local time produced fountaining of lava several hundred meters high and appears to have caused a small pyroclastic flow. –Volcano Discovery

New Zealand community told to prepare for major quake along dangerous Alpine Fault

Alpine Fault
March 2015 NEW ZEALAND - A West Coast community will need to consider drastic changes to its town to prepare for an inevitable Alpine Fault earthquake. The fault runs diagonally through Franz Josef Township and geologists have recommended a “fault avoidance zone” 100 meters either side to protect buildings. GNS Science sent four of its geologists to Franz Josef to talk about what will happen when the Alpine Fault ruptures. The 600-kilometre fault has ruptured five times in the past 1100 years. Each time it produced an earthquake of magnitude 7.0 to 8.0, the last being in 1717. Dr Ursula Cochran said studying the fault was complicated because different sections had ruptured at different times. While researching a section of the fault in South Westland, Cochran and her team found evidence for 24 earthquakes over 8000 years. Based on this and similar research, scientists calculated the average interval between earthquakes was about 300 years in South Westland.
From that information, scientists conclude there is a 30 per cent chance of a large earthquake occurring on the southern section of the fault in the next 50 years. That is considered reasonably high by global standards. Fellow geologist Dr Jamie Howarth said an Alpine Fault earthquake would be accompanied by dramatic changes in the Southern Alps in the following decades. Scientists had found evidence of an influx of erosion material flowing into lakes and rivers following a large earthquake. Howarth said that could be seen as a “considerable delayed hazard” with implications for restoration of infrastructure such as road and rail links. Dr Rob Langridge has worked to map the fault and determine how much it will slip in the next large earthquake. He said there would likely be instantaneous movement between 7 to 8 meters horizontally and 1 to 2m vertically. Langridge has worked on the concept of a “fault avoidance zone” which is being considered for the Franz Josef Township. It would mean a 100m-wide zone along the fault, which runs diagonally through the township, with special considerations for buildings. The Westland District Council has proposed changes to its district plan to account for the earthquake risk in Franz Josef. It will hear public submissions on the changes on March 30 and 31. –Stuff NZ

Alternative factor: minor setback could delay LHC start-up by as much as five weeks

CERN Parallel Worlds
March 2015TECHNOLOGY - It may have been two years since the Large Hadron Collider went to sleep at the CERN headquarters but scientists are stirring to get it back up and running. Unfortunately all the experiments that have been waiting for the power up will have to wait as a short circuit has delayed the restart of the machine. Indeed, officials say that a minor glitch has forced a delay in the re-start of the world’s largest particle smasher, Europe’s multi-billion dollar Large Hadron Collider.
Actually the team found that a small metallic piece near one of the magnetic components needs to be removed before they can really get the machine going again; and this could take a week or so. But while this mishap is unexpected it is somewhat understandable, as CERN Director for Accelerators Frédérick Bordry explains: “Any cryogenic machine is a time amplifier, so what would have taken hours in a warm machine could end up taking us weeks.”
And even with this tiny snafu all systems are still go; no one on the team seems to be phased by it. As a matter of fact CERN Director General Rolf Heuer explains, “All the signs are good for a great run 2. In the grand scheme of things, a few weeks delay in humankind’s quest to understand our universe is little more than the blink of an eye.” Hopefully removing this small piece of metal will be easy. If the removal process is simple, the machine could be ready to fire up again in just a matter of days. If, however, the machine needs significant repairs it could take as many as five weeks before it will be ready for another attempt. –Pioneer News

A stiff new layer in Earth’s mantle? Earth’s interior hotter than previously believed

Earth Mantle
March 2015GEOLOGY – By crushing minerals between diamonds, a University of Utah study suggests the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets three times stiffer. The discovery may explain a mystery: why slabs of Earth’s sinking tectonic plates sometimes stall and thicken 930 miles underground. The findings — published today in the journal Nature Geoscience — also may explain some deep earthquakes, hint that Earth’s interior is hotter than believed, and suggest why partly molten rock or magmas feeding mid-ocean-ridge volcanoes such as Iceland’s differ chemically from magmas supplying island volcanoes like Hawaii’s.  “The Earth has many layers, like an onion,” says Lowell Miyagi, an assistant professor of geology and geophysics at the University of Utah. “Most layers are defined by the minerals that are present. Essentially, we have discovered a new layer in the Earth. This layer isn’t defined by the minerals present, but by the strength of these minerals.” Earth’s main layers are the thin crust 4 to 50 miles deep (thinner under oceans, thicker under continents), a mantle extending 1,800 miles deep and the iron core. But there are subdivisions. The crust and some of the upper mantle form 60- to 90-mile-thick tectonic or lithospheric plates that are like the top side of conveyor belts carrying continents and seafloors.
Oceanic plates collide head-on with continental plates offshore from Chile, Peru, Mexico, the Pacific Northwest, Alaska, Kamchatka, Japan and Indonesia. In those places, the leading edge of the oceanic plate bends into a slab that dives or “subducts” under the continent, triggering earthquakes and volcanism as the slabs descend into the mantle, which is like the bottom part of the conveyor belt. The subduction process is slow, with a slab averaging roughly 300 million years to descend, Miyagi estimates. Miyagi and fellow mineral physicist Hauke Marquardt, of Germany’s University of Bayreuth, identified the likely presence of a superviscous layer in the lower mantle by squeezing the mineral ferropericlase between gem-quality diamond anvils in presses. They squeezed it to pressures like those in Earth’s lower mantle. Bridgmanite and ferropericlase are the dominant minerals in the lower mantle. The researchers found that ferropericlase’s strength starts to increase at pressures equivalent to those 410 miles deep — the upper-lower mantle boundary — and the strength increases threefold by the time it peaks at pressure equal to a 930-mile depth.
And when they simulated how ferropericlase behaves mixed with bridgmanite deep underground in the upper part of the lower mantle, they calculated that the viscosity or stiffness of the mantle rock at a depth of 930 miles is some 300 times greater than at the 410-mile-deep upper-lower mantle boundary. “The result was exciting,” Miyagi says. “This viscosity increase is likely to cause subducting slabs to get stuck — at least temporarily — at about 930 miles underground. In fact, previous seismic images show that many slabs appear to ‘pool’ around 930 miles, including under Indonesia and South America’s Pacific coast. This observation has puzzled seismologists for quite some time, but in the last year, there is new consensus from seismologists that most slabs pool.” How stiff or viscous is the viscous layer of the lower mantle? On the pascal-second scale, the viscosity of water is 0.001, peanut butter is 200 and the stiff mantle layer is 1,000 billion billion (or 10 to the 21st power), Miyagi says.
Slab subduction triggers earthquakes and volcanoes
For the new study, Miyagi’s funding came from the U.S. National Science Foundation and Marquardt’s from the German Science Foundation. “Plate motions at the surface cause earthquakes and volcanic eruptions,” Miyagi says. “The reason plates move on the surface is that slabs are heavy, and they pull the plates along as they subduct into Earth’s interior. So anything that affects the way a slab subducts is, up the line, going to affect earthquakes and volcanism.” He says the stalling and buckling of sinking slabs at due to a stiff layer in the mantle may explain some deep earthquakes higher up in the mantle; most quakes are much shallower and in the crust. “Anything that would cause resistance to a slab could potentially cause it to buckle or break higher in the slab, causing a deep earthquake.” Miyagi says the stiff upper part of the lower mantle also may explain different magmas seen at two different kinds of seafloor volcanoes.
Recycled crust and mantle from old slabs eventually emerges as new seafloor during eruptions of volcanic vents along midocean ridges — the rising end of the conveyor belt. The magma in this new plate material has the chemical signature of more recent, shallower, well-mixed magma that had been subducted and erupted through the conveyor belt several times. But in island volcanoes like Hawaii, created by a deep hotspot of partly molten rock, the magma is older, from deeper sources and less well-mixed. Miyagi says the viscous layer in the lower mantle may be what separates the sources of the two different magmas that supply the two different kinds of volcanoes.  –Science Daily

Climate change study has revealed Gulf Stream system slow down

March 2015CLIMATE CHANGE - The Gulf Stream is one of the most important heat transport systems on the planet. It efficiently brings heat from the equator to the Northern Hemisphere through ocean currents. But a recent study indicates that it has been slowing down, which is most interesting because it results in cooling of the region when most other parts of the world are warming up. Michael Mann, one of the study researchers, comments, “Common climate models are underestimating the change we’re facing, either because the Atlantic overturning is too stable in the models or because they don’t properly account for Greenland ice sheet melt, or both. That is another example where observations suggest that climate model predictions are in some respects still overly conservative when it comes to the pace at which certain aspects of climate change are proceeding.”
The Distinguished Professor of Meteorology at Penn State, comments that the new study found evidence that this Atlantic overturning, or the Gulf Stream system is, indeed slowing down. And this, of course, means, less warm ocean water from the tropics and Southern Hemisphere is getting pumped north, alternately less cold water is getting pushed southward.
Study author Stefan Rahmstorf, of the Potsdam Institute for Climate Impact Research (PIK), comments, “If the slowdown of the Atlantic overturning continues, the impacts might be substantial. Disturbing the circulation will likely have a negative effect on the ocean ecosystem, and thereby fisheries and the associated livelihoods of many people in coastal areas. A slowdown also adds to the regional sea-level rise affecting cities like New York and Boston. Finally, temperature changes in that region can also influence weather systems on both sides of the Atlantic, in North America as well as Europe.” –PN
