During 12-18 September there were some brief periods of NW winds that could mark the beginning of gradual wind transition from SE to NW winds, directions that would blow ash plumes away from Rabaul Town. Source: Rabaul Volcano Observatory (RVO) 10 June-16 June 2009 Cite this Report RVO reported that during 7-11 June white and occasionally blue plumes from Rabaul caldera's Tavurvur cone rose 1.5 km above the crater

Mr Cameron relates that on the morning of June 10th, he and the Vicar of Lyme Regis were on the ground close to the burning-mound, which was smoking as usual; but about half-past one on that day he was told that a landslip had taken place, and that the mound had been split in two by a fissure, so that its interior was exposed, looking like the inside of a brick-kiln, from the baked appearance of the shale and stone. The outward surface of the rock, at this part of the cliff, is very hot, as well the soil around the apertures, and small fragments of the stone retains very considerable degree of heat for a long time, after being detached from the larger blocks

The Journal of the American Medical Association stated in their September 18, 1943 issue, that "fluorides are general protoplasmic poisons that change the permeability of the cell membrane by certain enzymes." And, an editorial published in the Journal of the American Dental Association, October 1, 1944, stated, "Drinking water containing as little as 1.2 ppm fluoride will cause developmental disturbances.

GregK says: April 23, 2015 at 9:20 pm No Because the planet is moving across the hot spot so crust is being renewed along with volatiles Will it be an eruption from the current magma chamber or will it solidify and the big one will be from the next magma chamber in Montana? When it does blow life will certainly be uncomfortable for the whole planet for a while and, depending on the wind, North America in particular. As there have been three such eruptions in about the past 2,100,000 years, there are only two inter- eruptive periods from which to gauge any additional possible interval between the third and a potential fourth such event

stevengoddard says: April 19, 2010 at 4:56 am Tenuc (02:49:06) : A rising plume of very hot gas and ash generates a lot of friction, and thus charged particles and lightning. Depending on the degree of melting and the temperatures reached, the water either is incorporated into the mineralogy (plutonic rocks); is exsolved on the way up (basaltic to andesitic volcanics); or remains in the magma to help produce the explosive volcanics (andesitic to rhyolitic)

14, 2009) - The most detailed seismic images yet published of the plumbing that feeds the Yellowstone supervolcano shows a plume of hot and molten rock rising at an angle from the northwest at a depth of at least 410 miles, contradicting claims that there is no deep plume, only shallow hot rock moving like slowly boiling soup. Sunday, June 8, 2014 8:14 AM PDT (Sunday, June 8, 2014 15:14 UTC) Is Mauna Loa volcano beginning to stir? Over the past 13 months, the Volcano Observatory in Hawaii has recorded increased activity on the flanks and summit of Mauna Loa, the largest volcano on Earth

The San Andreas fault might also buckle, causing most of California to be devastated.Let us now briefly review this historic record of past super volcanic eruptions from Yellowstone Park. Russia is simply following the Illuminati Plan to cause enough massive disruption in the United States that our authorities would have the excuse to impose Martial Law, dissolving our Constitutional form of government and take our liberties away

For those who do not know much about the theory of plate tectonics; it states that there are twenty plates that cover most of the Earth's surface area.... For decades its water sources were tapped by the Los Angeles Department of Water and Power (DWP) to use for farming because the lake's high elevation would allow them to easily transport the water to the city and because the water was so saline, people believed it was worthless

Dams and reservoirs on several rivers could lessen the extent of future lahars by trapping all or much of the flow, but they could also increase a lahar's extent if a lahar displaced reservoir water and caused dams to fail. Geologists use this and other evidence to assess future hazard potential and to map zones in river valleys heading on Mount Rainier that could be inundated by future lahars

The size of a volcano is usually measured in terms of the volume of material erupted during its active life, and individual eruptions are measured in terms of the volume of material erupted during a particular period of activity. Gas-charged magma erupts at the surface in a fire-fountain which may play continuously (Hawaiian style) or pulsate discontinuously (Strombolian style) to build a cone of coarse tephra, commonly referred to as a scoria cone

This function includes the USGS Hazard Response Executive Committee, which provides executive direction, oversight, and support to USGS managers in responding to major hazard events. The USGS monitors active and potentially active volcanoes, assesses their hazards, responds to volcanic crises, and conducts research on how volcanoes work

Volcanic Gases and Their Effects

It also causes acid rain downwind from volcanoes because HCl is extremely soluble in condensing water droplets and it is a very "strong acid" (it dissociates extensively to give H+ ions in the droplets). At low concentrations it can irritate the eyes and acts as a depressant; at high concentrations it can cause irritation of the upper respiratory tract and, during long exposure, pulmonary edema

For example, low-silica basalt lava can form fast-moving (10 to 30 miles per hour) streams or can spread out in broad thin sheets as much as several miles wide. This simplified sketch shows a volcano typical of those found in the Western United States and Alaska, but many of these hazards also pose risks at other volcanoes, such as those in Hawaii

Vog is created when SO2 and other volcanic gases combine and interact chemically in the atmosphere with oxygen, moisture, dust, and sunlight over periods of minutes to days. In contrast to SO2 gas concentration near Kilauea, the amount of aerosol particles in Hawaii's air does not routinely exceed Federal standards, but the unique combination of acidic particles, trace amounts of toxic metals, and SO2 gas in vog may account for the wide variety of physical symptoms reported
