Volcanoes: Japan’s Mount Ontake eruption deaths likely to surpass 60 – Iceland volcano rocked by more quakes

October 2014NAGANO, Japan The eruption of Mount Ontake has left 16 missing and 47 dead so far, but phone calls and other records indicate the numbers are likely to grow, Nagano prefectural officials said Friday. After examining records assembled by police, firefighters and town officials, including missing persons reports and, in some cases, testimony from hikers who survived but have been unable to find their climbing companions, the true toll from the disaster is set to climb. Police said earlier that 46 of the 47 victims were bludgeoned to death by falling rocks ejected by the eruption and the other victim died of burns, although no magma was observed. On Friday, rain again forced the suspension of search and rescue operations on the 3,067-meter volcano, which straddles Nagano and Gifu prefectures. The search teams were drawn from the Nagano Prefectural Police, firefighters and Ground Self-Defense Forces. Rescuers are bringing the bodies off the mountain by helicopter and had recovered 47 by Wednesday. In Japan’s most deadly volcanic eruption in modern history, the top of Mount Ontake blew shortly before noon last Saturday, just when many hikers had reached the summit and were enjoying lunch in the autumn sunshine, enjoying clear views of the Northern Alps. Fall is the mountain’s busiest climbing season.
Day after day, bad weather has hampered the search for survivors and bodies, which may now lie beneath 30 cm or more of ash. And with a typhoon approaching early next week, the searchers might soon face the risk of ash-laden mudslides triggered by heavy rain. The layers of ash and freshly fallen rocks will make for unstable trekking as well. The Meteorological Agency projected heavy rain overnight, with up to 30 mm falling in Nagano by 6 a.m. Saturday and 40 mm in parts of adjacent Gifu. The Land, Infrastructure, Transport and Tourism Ministry warned that mudslides near Mount Ontake could cause the rivers below to flood, but said the areas most at risk are uninhabited. The town of Kiso, Nagano Prefecture, said it would evacuate residents at risk of landslides if a warning for heavy rain is issued. On Thursday, search activities were halted shortly before noon by rain, while previous forays were stopped by volcanic tremors and toxic gas. Ontake’s last major eruption was in 1979. It had minor eruption in 1991 and multiple volcanic tremors in 2007. –Japan Times                            
                                        Northern Iceland being transformed into volcanic hell
Iceland Volcano update: Fifty earthquakes have been picked up by sensors around the Holuhraun eruption site since 7 pm yesterday, according to the Icelandic Met Office’s update this morning. Most of the earthquakes have occurred in Bárðarbunga caldera and other in the northern part of the intrusive dike, channeling magma from the volcano to the fissure eruption in Holuhraun. Seven earthquakes larger than magnitude 3.0 hit the northern part of Bárðarbunga caldera since yesterday evening, the strongest of which measured magnitude 4.8 and occurred at 1:41 am. One minor earthquake of magnitude 2.4 hit at 9:57 yesterday evening 10.4 km (6.8 miles) southwest of Kópasker, Northeast Iceland. –Iceland Review
Sulfur dioxide (SO2) pollution from the Holuhraun eruption could be detected in Hvalfjörður, West Iceland, yesterday evening and in Norðlingaholt suburb of Reykjavík in the early afternoon. However, with maximum levels of 800 µg/m3 and 160 µg/m3, respectively, the pollution is much less severe than what it has been in North and East Iceland. On Wednesday morning a record SO2 level of 5,800 µg/m3 was measured outside the school Reykjahlíðarskóli by Lake Mývatn in Northeast Iceland. The highest level until then was 4,000 µg/m3, measured in Reyðarfjörður, East Iceland, about one month ago, ruv.is reports. At such high SO2 levels—above 2,000 µg/m3—people are advised to stay indoors. The levels are based on a ten-minute average and they rarely remain high for long periods at a time. By Lake Mývatn on Wednesday, the SO2 levels had dropped again by the time the school started at 8:30 am and so teaching took place as usual. –Iceland Review

    What has been interesting about this event(Iceland) is that many of us have been expecting an large eruption as we all see, but the interesting part has been the continual release of the Sulfur dioxide which of course is a toxic gas and and is also known to be part city air pollution or acid rain. Last month on a post on this site, the smell/odor reached Norway. The folks in Iceland are experiencing some respiratory issues, no doubt.

    no doubt.
    here’s what the National Park Svc in Hawaii has to say on the subject:
    http://www.nature.nps.gov/air/AQBasics/understand_so2.cfm

    “…Sulfur dioxide irritates the skin and mucous membranes of the eyes, nose, throat, and lungs. High concentrations of SO2 can cause inflammation and irritation of the respiratory system, particularly during heavy physical activity. The resulting symptoms may include pain when taking a deep breath, coughing, throat irritation, and breathing difficulties. High concentrations of SO2 can affect lung function, worsen asthma attacks, and aggravate existing heart disease in sensitive groups. This gas can also react with other chemicals in the air and convert to a small particle that can lodge in the lungs and cause similar health effects….
    “People particularly sensitive to sulfur dioxide include:
    People with lung diseases, such as asthma, chronic bronchitis, and emphysema will generally experience more serious health effects at lower SO2 levels.
    Children are at higher risk from SO2 exposure because they are more likely to have asthma, which may be aggravated by SO2 exposure. Their lungs are still developing.
    Older adults may be more affected by SO2 exposure, possibly because they are more likely to have pre-existing lung or cardiovascular disease.
    Active people of all ages who exercise or work vigorously outdoors have higher exposure to sulfur dioxide than people who are less active…”

    Accuweather update on Typhoon Phanphone, expected to make landfall in japan sometime tonight

    http://www.accuweather.com/en/weather-news/tokyo-japan-typhoon-phanfone/35131345
    “…The heaviest rain will bypass Tokyo and the rest of far southeastern Honshu to the north and west, instead targeting the zone from eastern Shikoku to the Honshu prefecture of Fukushima. Amounts of 150 to 250 mm (6 to 10 inches) are expected, triggering widespread and life-threatening flash flooding.
    “There will even be 300 millimeters (a foot) or more of rain in the mountains,” stated AccuWeather.com Meteorologist Adam Douty. That amount of rain is sure to cause not only flooding but also mudslides.
    Mount Ontake, site of Saturday’s deadly volcanic eruption, will be inundated with 100 to 200 mm (4 to 8 inches) of rain. Debris flows resulting from the torrential rain and ash are a serious concern around the volcano, further hindering the search for additional victims…”
