Volcanoes
Manam island is a volcanic cone that towers out of the sea north of the Papua New Guinea mainland and has a history of eruptions, with major activity in November 2004 forcing the evacuation of some 9,000 people.
The volcano has erupted a number of times since then and spewed lava and ash last month.
A series of tremors around Manam triggered a warning system on Monday and the volcano began erupting shortly after, the Rabaul Volcanological Observatory said.
Our colleague Marc Szeglat (www.vulkane.net) reported that continuous spattering, in addition to sometimes relatively strong strombolian explosions, can often be seen from from the NE vent.
A total of at least 7 vents are currently active (spattering, strong degassing and/or explosions) in the crater terrace.
The alert status of the volcano had been raised last week.

The Anak Krakatau volcano continues to throw out hot ash in a photograph taken from an Indonesian naval patrol boat on 28 December.
Scientists said Anak Krakatau now has a volume of 40-70 cubic metres, having lost up to 180m cubic metres of volume since the eruption on 22 December.
The analysis from Indonesia's Centre for Volcanology and Geological Disaster Mitigation demonstrates the power of the tsunami that crashed into 186 miles of coastline in Sumatra and Java.
More than 420 people died in the waves that reached up to 2m in height, and 40,000 were displaced.
The centre said the crater peak was 110m high on Friday, compared to 338m in September.
Experts have largely relied on satellite radar images to work out what happened to the volcano. Cloud cover, continuing eruptions and high seas have hampered inspections. The centre said it would get more precise results from further visual inspections.

John Woodrum, shovels his car on Sunday, Dec. 9, 2018, in Roanoke, Va. A massive storm brought snow, sleet, and freezing rain across a wide swath of the South on Sunday — causing dangerously icy roads, immobilizing snowfalls and power losses to hundreds of thousands of people.

This is the third such incident reported this year the state which is very close to Chittagong in Bangladesh.
Earlier in mid-April, at two spots, namely Baishnavpur and Ghagrabasti of Sunroom, lava-like liquid erupted along with fire and gas.
In the recent incident from a few days ago, the local villagers of Jalifa were scared to find lava erupting from the lower portion of the electric pole on the roadside and reported the matter to the fire extinguishing team and local police. A team of firefighters rushed to the spot and tried to spray water and foam, but failed to stop the ongoing eruption that had already burned the spot.
Meanwhile, scientists from the Department of Science, Technology and Environment of the Government of Tripura also visited the spot. After examining the spot and analysing the samples collected from the spot they concluded that the fire, smoke and other materials running out of the ground is due to a fault line that passes through that area beside the displacement of the underground tectonic plates in that region and which is creating huge subsurface heat causing the incident.
Comment: A few months ago a mysterious burning hole with flames shooting out of it was discovered in Midway, Arkansas which baffled geologists. See also:

Activity has recently returned to a moderate level following a hiatus for most of the year.
Explosions like this are typical for Sheveluch- many have happened in the past 25 years as dome-building continues.

Mount Agung volcano erupts, as seen from Kubu, Karangasem Regency in Bali, Indonesia on June 29, 2018.
Mount Agung has been erupting periodically since it rumbled back to life in 2017, when it grounded hundreds of flights and left 120,000 visitors stranded.
On Sunday morning, the volcano - which is about 70 kilometres from the tourist hub of Kuta - sent ash skywards as it erupted for about three minutes, according to the country's volcanology centre.
"Residents near Mount Agung as well as climbers and tourists should not carry out any activity in the danger zone or within a four-kilometre radius from the crater," the centre said in a statement.

The phreatic or ash explosions occurred at 8:17 a.m. and 8:28 a.m. that generated grayish to grayish white ash plumes 600 meters and 200 meters above the crater, respectively based on Phivolcs' latest bulletin.
Phivolcs director Renato Solidum said the explosions were possibly triggered by the sudden degassing of magma inside the volcano's chamber.
Mayon remains under Alert Level 2 after its full-blown eruption episodes that started January and simmered down in March early this year.











Comment: Meanwhile the number of injured in the volcano-triggered tsunami in Indonesia jumped significantly to 14,059 from 7,202 say reports, as search and rescue operations continue. See also:
