JELAWAT Intensifies to a Super Typhoon with 265kph Winds

Super Typhoon JELAWAT, described as “violent,” is currently packing maximum sustained winds of about 265 kilometer  per hour (kph), with wind gusts exceeding 325 kph, moving NNW in the Philippines Sea at forward speeds of about 12kph.

  • The Super Storm could top maximum sustained winds of 280kph in the next 12 hours, according to models.

Other Disasters, Significant Events

  • California, USA. A wildfire 50 miles east of San Diego has destroyed at least 3 dozen buildings including 20 houses, threatening more homes and forcing hundreds of residents to evacuate.
    • At least a dozen other homes have reportedly been damaged by the fire.
    • The 3,000-acre blaze may have started in Mexico, officials said.
  • Philippines Sea. Typhoon EWINIAR (TY 19W), currently positioned NNW of Mariana Islands, is heading north towards Tokyo, Japan with sustained winds of about 75kph.

Cleveland and Kīlauea Remain at ORANGE Alert

Explosion destroys dome in Cleveland summit crater

Sudden explosions of blocks and ash may occur, while the volcano remains active, with the ash clouds rising to above 20,000 feet above sea level, AVO said.

  • Elevation:  5,676 ft (1,730 m)
  • Location: 52.8222° N, 169.945° W
  • Quadrangle: Samalga

KILAUEA VOLCANO

19°25’16” N 155°17’13” W,
Summit Elevation 4091 ft (1,247 m)
Current Volcano Ale,rt Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary for past 24 hours:  The summit continued to inflate slowly while back-to-back DI events and sympathetic summit lava lake oscillations continued. Overnight, glow was visible within the Halema`uma`u gas plume and from sources within Pu`u `O`o crater. To the southeast, surface flows continued to be active on the pali and the coastal plain; there was no ocean entry. Seismic tremor levels were low; gas emissions were elevated: HVO


Kīlauea Volcano.  Active flows continued over a broad area on the coastal plain on April 5, 2012.  “This composite image combines a normal photograph and a thermal image to show the areas of active breakouts. Yellow areas are active flows while red areas are inactive, but still warm, flows. The flow front in the lower right was 1.6 km (1 mile) from the ocean,” HVO said.

Alert Level Increased for Iliamna Volcano, AK

Iliamna Activity – Color Code YELLOW Alert Level ADVISORY

Since January 2012 the earthquake rate at Iliamna Volcano has steadily increased and now exceeds normal background levels.

Pagan

Location: Mariana Islands  (18.13 ºN,  145.8 ºE)
Elevation: 570 m
Recent Eruption: 2006
Volcanic Alert Level: ADVISORY
Aviation Color Code: YELLOW

A gas and steam plume continued to extend downwind from the summit vent throughout the past week, but there were no further reports of unrest or activity at Pagan volcano, USGS said.

Mount Shasta and Shastina, California. USGS Photograph taken by Lyn Topinka, 1984 .

From: Miller, 1980, Potential Hazards from Future Eruptions in the Vicinity of Mount Shasta Volcano, Northern California: USGS Bulletin 1503

Mount Shasta is located in the Cascade Range in northern California about 65 kilometers (40 miles) south of the Oregon-California border and about midway between the Pacific Coast and the Nevada border. One of the largest and highest of the Cascade volcanoes, snowclad Mount Shasta is near the southern end of the range that terminates near Lassen Peak. Mount Shasta is a massive compound stratovolcano composed of overlapping cones centered at four or more main vents; it was constructed during a period of more than 100,000 years. … Two of the main eruptive centers at Mount Shasta, the Shastina and Hotlum cones were constructed during Holocene time, which includes about the last 10,000 years.

For more information including eruptive history and probable future potential hazard see: Mount Shasta and Vicinity, California


The most voluminous of the Cascade volcanoes, northern California’s Mount Shasta is a massive compound stratovolcano composed of at least four main edifices constructed over a period of at least 590,000 years.
Roughly 46 cu km of an ancestral Shasta volcano was destroyed by one of Earth’s largest known Quaternary subaerial hummocky debris avalanches, which filled the Shasta River valley NW of the volcano about 350,000 year ago.  The Hotlum cone, forming the present summit, and the Shastina lava dome complex were constructed during the early Holocene, as was the SW flank Black Butte lava dome. Eruptions from these vents have produced pyroclastic flows and mudflows that affected areas as far as 20 km from the summit. Eruptions from Hotlum cone continued throughout the Holocene. Shasta’s only historical eruption was observed from the ship of the explorer La Perouse off the California coast in 1786.  Photo by Dave Wieprecht, 1995 (U.S. Geological Survey). Caption: GVP


The deposits of an exceptionally large debris avalanche extend from the base of Mount Shasta volcano northward across the floor of Shasta Valley in northern California. The debris-avalanche deposits underlie an area of about 675 square kilometers, and their estimated volume is at least 45 cubic kilometers. Radiometric limiting dates suggest that the debris avalanche occurred between about 300,000 and 380,000 years ago. Hundreds of mounds, hills, and ridges formed by the avalanche deposits are separated by flat areas that slope generally northward at about 5 meters per kilometer. The hills and ridges are formed by the block facies of the deposits, which includes masses of andesite lava tens to hundreds of meters across as well as stratigraphic successions of unconsolidated deposits of pyroclastic flows, lahars, air-fall tephra, and alluvium, which were carried intact within the debris avalanche. The northern terminus of the block facies is near Montague, at a distance of about 49 kilometers from the present summit of the volcano. The flat areas between hills and ridges are underlain by the matrix facies, which is an unsorted and unstratified mudflowlike deposit of sand, silt, clay, and rock fragments derived chiefly from the volcano. Boulders of volcanic rock from Mount Shasta are scattered along the west side of Shasta Valley and in the part of Shasta Valley that lies north of Montague, at heights of as much as 100 meters above the adjacent surface of the debris-avalanche deposits. The boulders represent a lag that was formed after the main body of the avalanche came to rest, when much of the still-fluid matrix facies drained away and flowed out of Shasta Valley down the Shasta River valley and into the Klamath River. About 300 years ago, three rockfall-debris avalanches occurred from domes at the Chaos Crags eruptive center near Lassen Peak. The Chaos Crags avalanches traveled as far as 4.3 kilometers from their source areas. USGS Photograph taken September 22, 1982, by Harry Glicken. Caption: CVO

FEWW Volcanic Forecast:

(see: Sumatra’s Mt Kerinci Erupts )

1. The Loyalty – New Hebrides  Arc Collision. Intense volcanic activity should be expected throughout 2009 and beyond along the New Hebrides arc, the Vanatu region (also to the north to include Solomon Island and Santa Cruz Island), possibly continued along the New Hebrides Trench (to include Matthew and Hunter Island). Volcanoes that are located in the above-described area include:

  • Savo (Solomon Island)
  • Tinakula (Santa Cruz Island – SW Pacific)
  • Suretamatai
  • Motlav
  • Gaua
  • Mere Lava
  • Aoba
  • Ambrym
  • Lopevi
  • Kuwae
  • North Vate
  • Traitor’s Head
  • Yasur
  • Eastern Gemini Seamount
  • Matthew Island
  • Hunter Island

2. Pacific Plate subduction beneath the Okhotsk Plate. Subduction of the Pacific Plate beneath the Okhotsk Plate continues to create Intense volcanism. Starting 2009, however, a much greater than the average number of volcanoes located on the Kuril Islands island arc, Kamchatka volcanic arc and Japan trench to the south may erupt with renewed intensity.

Week 31 Volcano Watch

Recent activity at the Kilauea volcano has increased atmospheric levels of sulfur dioxide in the districts of Kau and Puna, Hawaii, resulting in a spike of sulfur of 9 parts per million, which is considered to be extremely high. (Source)
