Hawaiian lava lake hits new record high

January 17, 2012 – HAWAII – The orange glow atop Hawaii’s Mount Kilauea was a little stronger yesterday (Jan. 15) than it has been in recent weeks. The volcano’s lava lake lapped over the inner ledge of its vent, reaching a new high and bring molten rock closer than ever to the floor of Halema’uma’u crater. The level was about 80 feet (25 meters) below the crater floor, the highest level reached since the summit vent blasted open in March 2008, the U.S. Geological Survey reports. The lava lake last surged on Oct. 23, 2012, when the high mark was measured at 100 feet (31 m) below the crater floor. Since fresh lava appeared atop Kilauea in 2008, the lake level has varied from near the crater to out of sight, more than 650 feet (200 m) beneath the crater floor. The lake sits in a vent, which is actually a pipe-like crater within the smaller crater called Halema’uma’u. And Halema’uma’u is also a crater within a crater — the giant Kilauea caldera, the bowl left behind when the volcano blew its top about 1500 A.D. The USGS also reports that activity is up at Pu’u ‘O’o crater, 12 miles (19 kilometers) from the summit in the volcano’s East Rift Zone. The crater was awash with lava flows in recent days, and lava overflowed from its northeast lava lake and north spatter cone, the USGS said in a statement. At the coast, oozing flows continues to slowly drop into the ocean. This month marks the 30th anniversary of the eruption at Kilauea’s East Rift Zone. The volcano’s longest continuous rift zone eruption since the 15th century, the massive upwelling has created more than 500 acres of new land. -OAP

New Zealand rattled by 11,000th aftershock, following 2010 earthquake

January 17, 2012 – NEW ZEALAND – A magnitude-3.3earthquake that struck Christchurch this afternoon could be the 11,000th tremor since September 4, 2010. The quake hit at 12.55pm, 15 kilometers east of Christchurch at a depth of 6km. Over 163 people reported feeling the “moderate” shake on the GeoNet website. According to Christchurch Quake Map, the quake was the 11,000th the region has experienced since the magnitude-7.1 struck early on September 4 2010. GNS Science geological hazard modeler Matt Gerstenberger said 11,000 quakes was a significant but expected number for the region to have experienced. “Anyone living there knows what it has been like. However, it is in the range of what we would have expected for a region which has had a large earthquake.” Many of those quakes would not have been felt, he said. “Many would have been so small they wouldn’t have been noticed. Also, I’m not sure what the minimum magnitude for a quake is that is mapped on that website, but that [11,000] figure would be in the range, I suspect.” He did not expect the number of quakes mapped to go up greatly. “According to the aftershock sequence, the aftershocks will now be further apart and so the number will go up slowly over time,” he said. “There won’t be a huge or sudden increase.” –Stuff.NZ

More aggressive eruptive activity seen at many of world’s active volcanoes

January 17, 2012 – EARTH – Stromboli (Italy): The lava overflow that started on Monday and reached about 400 m elevation on the Sciara del Fuoco has stopped (for now).  Strong explosions felt in houses in the village continue to occur frequently and tremor remains elevated. Etna volcano: The strombolian activity inside Bocca Nuova crater has ended abruptly yesterday. Colima (Mexico) has entered a new eruptive phase withmore explosions during the past days. Popocatépetl (Mexico): Activity has not changed significantly: there are 1-2 weak emissions per hour, sometimes producing small quantities of ash. Glow from the summit remains visible at night. Some small volcanic earthquakes (below M2) have been occurring in the past days as well. Santiaguito (Guatemala): The activity has remained essentially unchanged but lower than last week. During 14-15 Jan, few weak explosions occurred from the dome, and glowing avalanches were observed from the fronts of the active lava flows on its flanks. Pacaya (Guatemala): Increased steaming has been observed today, but otherwise, there has not been any new activity. Numerous small earthquakes continue to be visible as evidence of fluid movements under the volcano. Fuego (Guatemala): Activity has been decreasing with few explosions and the lava flow reducing its length to 300 m. Nicaragua’s San Cristobal, Masaya and Concepcion volcanoes have not shown appreciable changes in their (seismic) activity of varying amounts of volcanic earthquakes and tremor. Nevado del Ruiz (Colombia): No other activity than degassing has been reported recently. Seismic activity remains elevated but at relatively low levels. A swarm of earthquakes occurred under the volcano on 15 Jan afternoon. Very small, but numerous, earthquakes are occurring at Machin, Galeras, and Cumbal volcanoes in Colombia. Reventador (Ecuador): Strong seismic activity including some explosion signals and a hot spot visible on satellite images suggest that the lava dome in the summit crater continues to be active. Tungurahua is currently calm. Copahue (Chile/Argentina border): No surface activity and no glow has been observed, but there is elevated seismic activity of low energy with more than 1700 events detected between 15-16 Jan. Alert level remains at Orange because of the risk of sudden phreatic explosions. Lokon-Empung (North Sulawesi, Indonesia): Another explosionoccurred this morning at 09:33 local time. It was weaker than the previous ones and produced a plume rising to about 12,000 ft (3.6 km) altitude and drifting NE, VAAC Darwin reported. Kilauea (Hawai’i): Activity has been stable with good magma supply maintaining relatively high levels of the lava lakes and feeding lava flows that continue to reach the ocean. Sakurajima volcano in Japan has maintained a rythm of 2-3daily explosions with ash plumes rising to 6-10,000 ft (1.8-3 km) altitude. White Island (New Zealand): The tremor has increased significantly during the past 24 hours. If this is caused by the volcano (and not wind), it could suggest a new eruption under way, but there have been no reports of any activity so far. Kizimen (Kamchatka): The new lava flow from the summit dome continues to be active on the north-eastern flank of the volcano. Incandescence of the volcano summit, hot avalanches and strong degassing accompany this process, KVERT reports. Tolbachik (Kamchatka): The eruption still continues with active lava flows being fed by the southern vent. KVERT reports tremor at higher levels than during the past week.  –Volcano Discovery

Ebola virus spreading to Asia: fruit bats in Bangladesh test positive for ebola antibodies

January 17, 2012 – BANGLADESH – EcoHealth Alliance, a nonprofit organization that focuses on local conservation and global health issues, released new research on Ebola virus in fruit bats in the peer reviewed journal, Emerging Infectious Diseases, a monthly publication by the Centers for Disease Control and Prevention (CDC). The study found Ebola virus antibodies circulating in ~4% of the 276 bats scientists screened in Bangladesh. These results suggest that Rousettus fruit bats are a reservoir for Ebola, or a new Ebola-like virus in South Asia. The study extends the range of this lethal disease further than previously suspected to now include mainland Asia. “Research on Filoviruses in Asia is a new frontier of critical importance to human health, and this study has been vital to better understand the wildlife reservoirs and potential transmission routes for Ebola virus in Bangladesh and the region,” said Dr. Kevin Olival, lead author and Senior Research Scientist at EcoHealth. Ebola virus, named after a river in the Democratic Republic of the Congo in Africa, where it was first recognized causes the disease – Ebola hemorrhagic fever. Ebola hemorrhagic fever is a severe, often-fatal disease in humans and non-human primates (monkeys, gorillas, and chimpanzees) that has appeared sporadically since its initial detection in 1976. Ebola virus is one of two members of a family of RNA viruses called the Filoviridae. Filoviruses are zoonotic pathogens (diseases that are transmitted from animals to humans) that cause lethal hemorrhagic symptoms among humans and non-human primates with case fatality rates up to 80 percent. Natural reservoirs of filoviruses have remained elusive for decades but current literature suggests that bats may be the primary natural hosts of Ebola virus. EcoHealth Alliance works to understand the dynamics of emerging diseases and the ecology of associated wildlife reservoirs to prevent and better control potentially pandemic outbreaks. “Bats tend to have a bad reputation and that’s unfortunate since they provide services that are vital for maintaining healthy ecosystems. Increasingly, spillover of viruses from bats and other wildlife occurs due to increased human activities that bring people into closer contact with wildlife, such as land-use change and agricultural practices. The next step is to determine whether this Ebola virus is actually causing disease in people, and if so, work to develop strategies that reduce contact with bats to protect human health, without harming bats,” said Dr. Jonathan Epstein, coauthor and Associate Vice President at EcoHealth Alliance. –Medical Xpress

Thousands of dead fish wash up on coast of South Carolina

January 16, 2012 – PAWLEYS ISLAND, SC There is a mystery along the South Carolina coast. Thousands of dead fish washed up on the beach at the south end of  Pawleys Island Tuesday afternoon. The fish are menhaden, and the SC Department of Natural Resources have been notified of the incident. Menhaden fish are a small, oily fish that are used for fish oil and its oil is also an ingredient in lipstick and they are also used for livestock feed. -WLTX
Mystery intensifies over fish kill: Thousands of Atlantic menhaden – a baitfish that plays a key role in the South Atlantic ecosystem – were found washed up on the beaches in the south area of the Grand Strand on Tuesday and Wednesday, leaving S.C. Department of Natural Resources investigators trying to determine the cause. From DeBordieu, a private community just north of Georgetown, northward to Pawleys Island, a rough estimate of 30,000 to 40,000 menhaden in the 6-to-8 inch range were spread along the beach and first spotted by beachgoers taking advantage of the unseasonably warm weather. Researchers from the University of South Carolina’s Belle Baruch Institute for Marine & Coastal Sciences took ocean water samples from where the menhaden washed ashore at DeBordieu and found typical winter conditions in levels such as dissolved oxygen and salinity. A reddish slick was noticed in the water near the beach which researchers found to be decaying fish matter from the dead menhaden. When a fish kill occurs in the ocean, the culprit is often found to be an algal bloom such as red tide, widespread low levels of dissolved oxygen or, especially in the winter, colder-than-normal ocean water temperatures. The testing ruled out an algal bloom and widespread areas of low dissolved oxygen, or hypoxia, and the water temperature is above normal thanks to the recent stretch of warm weather. Mel Bell, Director of the Office of Fisheries Management for S.C. DNR, provided his agency’s theory on the kill. “On Friday we had a new moon (which caused) real high high tides and real low low tides,” said Bell. “Probably what happened was a school (of menhaden) got in an area of water on a high tide, in a hole or depression, and at low tide they were trapped and depleted the oxygen in the water. Then, all the fish would suffocate.  “We don’t know for certain, but given the results of the water sample analysis and the tides, that’s probably the best working hypothesis. Then when the tide came back in, it washed the dead fish out and they washed up on the beach.” -MBO

One dead, 900 hurt in heavy Japan snowfall

January 16, 2013 – JAPAN Heavy snow that blanketed eastern Japan over the holiday weekend left one man dead and 900 others injured, as Tokyo commuters Tuesday took to the slippery streets. A low-pressure system, dubbed a “bomb cyclone” by local press, dumped eight centimetres (three inches) of snow in nine hours, the heaviest snowfall in the region since January 2006, the Japan Meteorological Agency said. It left 13 centimeters of snow in neighboring Yokohama, while mountainous areas around Tokyo saw up to 30 centimeters.  A 71-year-old man in Shiojiri city, Nagano prefecture, died after falling into an open drain as he cleared snow around his house, a fire service spokesman said. National broadcaster NHK said at least 891 injuries had been recorded in Tokyo and the area around it, many of them elderly people who had slipped on snow-covered streets or motorists involved in accidents. The operator of the Tokyo Skytree, a 634-metre (2,080-foot) tower in the capital that opened last year, said security guards were patrolling the base to keep people away from possible ice falls. “We haven’t received any reports of damage or injury from falling blocks of snow,” said spokeswoman Ayumi Kimura, adding around 60 guards were in the area Tuesday. “We have confirmed snow has fallen in tiny chunks. But there has been a limited amount of snow that has fallen on the tower.” Major train services resumed operations in Tokyo, although many sections of road remained closed while crews cleared frozen snow. All Nippon Airways and Japan Airlines cancelled a combined total of 37 domestic flights while dozens of other flights experienced delays. International operations were not severely affected by the snow, the airlines said. On Monday, Japanese airlines cancelled more than 460 domestic flights, mainly to or from Tokyo’s Haneda airport, where runways were temporarily closed as workers removed snow. Around 3,400 people spent the night at Tokyo’s Narita airport on Monday, a spokesman said after train services running to the outlying facility were suspended. They returned to normal on Tuesday, he added. –Terra Daily
