Eruption at Bulusan Volcano; Classes suspended in two towns in the Philippines
Bulusan Volcano in Sorsogon province spewed ashes anew Tuesday morning producing a 1-kilometer high grayish steam and ash plume which drifted towards the west-southwest.
The volcano, which has similar unrest just more than a month ago, generated two steam-driven explosions at 11:02 am and 11:20 am yesterday, the first event lasted for approximately 10 minutes
The ash column, according to accounts of local residents of Barangay Cogon in Irosin town, was accompanied by rumbling sound. The second event was smaller and lasted for about 1 minute based on seismic record.
“We have immediately deployed personnel in the area to conduct initial assessment of the possible areas most likely to be affected by the ashes once they dropped upon reaching its peak,” said Engr. Raden D. Dimaano, chief of the Provincial Disaster Risk Reduction Management Office of Sorsogon.
Mayor Antonio H. Alindogan immediately activated the Municipal DRRM Council thru SMS and verbal communication and declared suspension of classes in affected barangays and designated evacuation centers.
He likewise coordinated with the Philippine Army to be on standby for transportation, search and rescue and retrieval operation; the Philippine National Police for transportation, peace and order, traffic control; the Bureau of Fire Protection for possible fire incidence and washing-out of ashes in affected areas; the Department of Education to ready the evacuation centers; and with the Department of Interior and Local Government for on-time reports and accurate instructions to convene the DRMM Council.
According to Juban Municipal Disaster Risk Reduction and Management Officer Lizpeth H. Nicolas said they conducted inventory of stockpiled goods for possible distribution to evacuees while Juban Quick Emergency Response Team (JQERT) assisted during site visit in affected barangays in the distribution of face masks to residents and advised community to stay indoor especially children, seniors, and person with illness.
“We have also alerted the residents of Brgy. Putting Sapa and Añog and were made ready for anytime possibility of evacuation,” said Nicolas.
In Juban, Brgy. Puting Sapa with 147 households was heavily affected by ashfalls. Other areas affected are Barangays Añog with 115 households, Bacolod with 303, Catanusan with 192, and Buraburan with 389 households.
Juban MDRRMC conducts continuous site inspection to affected barangays.
Meanwhile, DepEd Sorsogon initially reported that suspension of classes were put in effect in all levels, private and public, in Juban and Irosin towns in Sorsogon due to Mt. Bulusan’s restiveness.
Residents in Putting Sapa were already advised to evacuate in Juban Central School least the situation gets worst.
DepEd Schools Division Superintendent Danilo E. Despi along with other DepEd personnel right away conducted an on-site inspection and monitoring.
Alert Level 1 (abnormal) status is maintained over Bulusan Volcano. This indicates that hydrothermal processes are underway beneath the volcano that may lead to more steam-driven eruptions.
Phivolcs in its advisory reminded the local government units and the public that entry to the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to the possibility of sudden and hazardous steam-driven or phreatic eruptions.
“Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as ejection from any sudden phreatic eruption can be hazardous to aircraft,” said Phivolcs.
Furthermore, people living within valleys and along river/stream channels are also advised to be vigilant against sediment-laden stream flows and lahars in the event of heavy and prolonged rainfall.
DOST-PHIVOLCS is closely monitoring Bulusan Volcano’s activity and made assurance that any new development will be relayed to all concerned.

Thousands flee Volcano Sinabung eruption in Indonesia

A resident rides his motorcycle as Mount Sinabung spews ash at Namanteran village in Karo Regency, Indonesia’s North Sumatra province yesterday
More than 10,000 villagers have fled a rumbling volcano in western Indonesia this month, most in recent days after a series of violent eruptions, an official said yesterday.
Authorities raised the alert status of Mount Sinabung, on Sumatra island, to the highest level at the start of June after detecting a sharp increase in activity.
The volcano, which came back to life two years ago after a period of inactivity, erupted violently at the weekend, spewing hot ash and rocks high into the air.
Sinabung — which killed 16 people in a fierce eruption last year — was continuing to belch out a thick plume of smoke high into the sky yesterday, covering homes far away with a coating of ash.
Around 7,500 residents have been evacuated from their villages following the weekend eruptions, disaster agency official Tri Budiarto said.
They “left their homes on motorcycles, in cars and on military trucks. They were from six villages located in the danger zone south and southeast of the volcano,” he said.
Several thousand people fled their homes at the start of the month when the alert status was lifted, and the total number of evacuees now stands at 10,714, said the disaster agency. The evacuees are sheltering in government buildings and places of worship in Kabanjahe town, around 10 kilometres from Sinabung.
Volcanic activity remained high yesterday, with Sinabung spewing out rocks and hot gas over a distance of three kilometres four times since early morning, said Armen Putra, head of the volcano observation post.
“We could still feel tremors. Ash one to two millimetres thick covered roads and homes located 15 kilometres away,” he said. “It could take weeks before it eases, but for now, it is dangerous for people living nearby so we have recommended for them to evacuate.”
After Sinabung rumbled back to life in 2013, more than 10,000 people fled from nearby villages. Some have returned home but more than 6,000 of the original evacuees are still living in shelters.
The volcano has also had a devastating economic impact, with the disaster agency estimating it caused more than $100mn in damage last year and in 2013 in a broad range of areas, including infrastructure, farming and tourism.
Sinabung is one of 129 active volcanoes in Indonesia, which sits on the Pacific Ring of Fire, a belt of seismic activity running around the basin of the Pacific Ocean.

NEAR RECORD WATERS AT CHATFIELD’S DAM IN DENVER, COLORADO, USA

High water at Chatfield (credit: CBS)
Recent heavy rain combined with the melting of above-average snow pack in the South Platte River Basin have pushed water levels at Chatfield Reservoir to near historic readings.
As of 8:31 a.m. on June 16 the gauge at Chatfield was less than a foot shy of the highest crest on record.
That was 5,447.60 feet measured on May 25, 1980.

While the high water is causing some flooding at the park and has closed some boat ramps, it is still far from compromising the dam.
The water would have to reach 5,500 feet to top the flood control pool and crest the spillway.
It’d have to reach 5,527 feet to top the dam.
