Severe storms cut power to hundreds of thousands, prompt disaster declaration in AR, states of emergency in MS, AL

Powerful winter storms continue to pound the U.S.  northeast with high winds and heavy snow, forcing thousands of flight cancellations.

  • Governor Beebe has declared a statewide disaster in the wake of Tuesday’s winter storm. Hundred of thousands remain without power in Central Arkansas amid freezing temperatures.
    • Beebe made similar declarations on Wednesday to ease federal regulations for the transport of utility crews and supplies, as well as poultry and poultry feed.
  • Up to 10 inches of snow is forecast for northern New England
  • Storms dumped record snow in Arkansas and north Texas.
  • “White-out” conditions reported in Indianapolis.
  • At least a dozen people have been killed and dozens more injured in weather-related incidents.
  • Gov. Walker declared a state of emergency in Wisconsin last week as the winter storm approached.

Snow Record Broken

A record snowfall of 4 inches was set at Elko, NV on Wednesday. This breaks the old record of 3 inches set in 1923.

Nicaragua

San Cristóbal, Nicaragua’s tallest volcano, has erupted spewing a 1.3-km column of volcanic cloud into the air.

  • About 1,500 residents who live within a 3-km radius of the volcano have been told to leave the area.
  • The 1,745-meter volcano sits about 140km northwest of the capital Managua.

Fuego Volcano Erupts

Posted by feww on September 13, 2012

DISASTER CALENDAR SYMBOLIC COUNTDOWN: 1,280 Days Left

[September 13, 2012] Mass die-offs resulting from human impact and the planetary response to the anthropogenic assault could occur by early 2016.

Guatemala’s Fuego volcano eruption forces tens of thousands of people to evacuate

Fuego’s powerful explosions ejected smoke and ash about 4km into the air, spewing two lava stream down the volcano flanks, accompanied by thousands of tons of volcanic ash and tephra.

About 35,000 people from two dozen villages nearest to the volcano have been evacuated, awaiting evacuation, or are on notice to abandon their homes depending on the wind direction, authorities said.

  • The 3,763 m volcano, dubbed the ‘Volcano of Fire,’  sits about 10km SW of the colonial city of Antigua (Pop: ~ 50,000) , Guatemala’s former capital, and is one of Central America’s most active volcanoes.

Nicaragua: 3,000 people are being evacuated as San Cristóbal volcano explodes

San Cristobal, Nicaragua’s highest volcano, exploded at least 3 times, expelling volcanic gases, ash and tephra about 1,500 meters into the air and forcing evacuations of thousands of people in the rural northwestern department of Chinandega.

Other Global Disasters/ Significant Events

United States.  Red Flag Warnings/Extreme Fire Danger. Critical Fire Weather Conditions are expected across parts of the Great Basin, Northern Rockies and Great Plains on Sunday, NWS said. Red Flag Warnings are in effect for parts of at least 12 states.

  • “Thunderstorms with little or no rain coupled with abundant lightning will offer a threat for critical fire weather conditions across portions of the northern Rockies on Sunday. Meanwhile, strong winds and low relative humidity will also create locally dangerous fire weather conditions across the northern and central Great Basin as well as the northern and central Great Plains.” NWS forecasters said.

VOW: Toba the Sleeping Colossus

Toba
Lake Toba, Sumatra, Indonesia – Landsat photo – Source: NASA

Lake Toba is a supervolcano, 100 kilometres long and 30 kilometres wide, and 505 metres (1,666 ft) at its deepest point. Located in the middle of the northern part of the Indonesian island of Sumatra with a surface elevation of about 900 metres (2,953 ft), the lake stretches from 2.88°N 98.52°E  to 2.35°N 99.1°E.  It is the largest volcanic lake in the world. It’s also the site of a supervolcanic eruption that occurred about 74,000 years ago, a massive climate-changing event. The eruption is believed to have had a VEI intensity of 8. This eruption, believed to have been the largest anywhere on Earth in the last 25 million years, may have had catastrophic consequences globally; some anthropologists and archeologists believe that it killed most humans then alive, creating a population bottleneck in Central Eastern Africa and India that affected the genetic inheritance of all humans today. (Source: Wikipedia).

Toba catastrophe theory

The Toba catastrophe theory holds that 70,000 to 75,000 years ago, a supervolcanic event at Lake Toba, on Sumatra, plunged the Earth into a mini-ice-age lasting several thousand years, reducing the world’s human population to 10,000 or even a mere 1,000 breeding pairs, creating a bottleneck in human evolution. The theory was proposed in 1998 by Stanley H. Ambrose of the University of Illinois at Urbana-Champaign.

The Toba eruption (the Toba event) occurred at what is now Lake Toba about 67,500 to 75,500 years ago. It had an estimated Volcanic Explosivity Index of 8 (described as “mega-colossal”), making it possibly the largest explosive volcanic eruption within the last twenty-five million years. It had a volume 300 cubic km greater than the Island Park Caldera supereruption (2500 cubic km) of 2.1 million years BP.

The total amount of erupted material was estimated at about 2,800 km³ — about 2,000 km³ of ignimbrite that flowed over the ground, and some 800 km³ that fell as ash, with the wind blowing most of it to the west. The pyroclastic flows of the eruption destroyed an area of 20,000 square kilometers, with ash deposits as thick as 600 metres near the main vent [ cf, 1980 eruption of Mount St. Helens ejected about 1.2 km³;  of material, whilst the largest volcanic eruption in historic times, at Mount Tambora in 1815, emitted the equivalent of 100 km3 of dense rock.] The eruption was also about three times the size of the latest Yellowstone eruption of Lava Creek 630,000 years ago. (Source: Wikipedia).

volcanic features of toba
The eruption of 73,000 years ago left the Sibandung caldera.  Lake Toba is surrounded by two small, active volcanos as well as several updomed areas and hot springs. These features indicate that there is activity below the surface today and that pressure is rising. Samosir island, too, is evidence for upthrust from below. From the record it seems that Toba produces major eruptions every 300-400,000 years. Source: Andaman Org.

Volcanic features in and around Lake Toba:

Grey area: Present-day topographic depression
green area: Updomed areas

Area # 1.  Sibandung caldera: made 73,000 years ago by the Toba YTT event (Young Toba Ash)
Area # 2. Haranggaol caldera: made 500,000 years ago by the Toba MTT event (Middle Toba Ash)
Area # 3.  Sibandung caldera: made 800,000 years ago by the Toba OTT event (Old Toba Ash)

The MTT and OTT events were not as large as the YTT event of 73,000 years ago
but were still major eruptions of at least VEI 7.

Recent Activity

Large earthquakes have occurred in the vicinity of the volcano more recently, notably in 1987.  Other earthquakes have occurred in the area in 1892, 1916, and 1920-1922.

Lake Toba lies near the Great Sumatran fault which runs along the centre of Sumatra called the Sumatra Fracture Zone. The volcanoes of Sumatra and Java are part of the Sunda Arc, a result of the northeasterly movement of the Indo-Australian Plate which is sliding under the eastward-moving Eurasian Plate. The subduction zone in this area is very active: the seabed near the west coast of Sumatra has had several major earthquakes since 1995, including the 9.3 2004 Indian Ocean Earthquake [followed by the deadly tsunami] and the 8.7 2005 Sumatra earthquake, the epicenters of which were around 300 km from Toba Lake. (Source: Wikipedia).

Notes [Source: GVP]

RVO reported that during 28 August-3 September white and gray ash plumes from Rabaul caldera’s Tavurvur cone rose 1.5 km above the crater and produced ashfall in Rabaul town (3-5 km NW) and surrounding areas.

The Washington VAAC reported that on 6 September an explosion from San Cristóbal produced an ash plume that rose to an altitude no higher than 8.5 km (28,000 ft) a.s.l. The plume drifted 75 km W.

Calm Before Volcanic Storm?

A quiet week for new volcanic activity, at least by recent standards. With Galeras excluded, for obvious reasons, there were only three new activities reported this week.

It’s interesting to note that the first mention of West Mata was apparently made in an entry on  Vents Program. The entry 2008 Expedition to Lau Basin appears to be dated November 27, 2008, but later updated, posted by John Lupton, Chief Scientist. Perhaps Mr Lupton could clarify whether his organization plays by “Las Vegas Rules.”

Our Thanks also to Dr. Erik Klemetti for acknowledging this blog as the main source of his entry on the Saudi Arabian earthquake swarm.  We would love to inspect Dr Klemetti’s doctoral thesis.
