Mount Sakurajima erupts in fiery blast

AP, KYODO, REUTERS, STAFF REPORT – FEB 5, 2016

Mount Sakurajima, a volcano that overlooks the city of Kagoshima, erupted Friday with a fiery blast that sent lava rolling down its slope.

The Meteorological Agency said Sakurajima, which is about 50 km from Kyushu Electric Power Co.’s Sendai nuclear plant in Kagoshima Prefecture, erupted at 6:56 p.m.

Local television showed an orange burst out of the side of the volcano, near the summit, accompanied by lightning-like flashes. Dark gray smoke billowed into the sky.

There were no immediate reports of injuries.

The Meteorological Agency banned entry to the area, expanding an existing no-go zone around the crater to a 2-kilometer radius.

Australia’s only two active volcanoes have both erupted in Feb 2016 – and scientists on board a ship conducting research nearby caught the rare event on film.

The Big Ben volcano on remote Heard Island in sub-Antarctica, almost 1800 kilometres north of Australia’s Antarctic base at Davis Station, erupted a combination of poisonous gases and red-hot lava. It was the first time it had done so in decades.

We witnessed the lava descending Big Ben interacting dramatically with the snow and ice cover of the mountain.

The other volcano, on the neighbouring McDonald islands, erupted gas only. Scientists on board the CSIRO’s RV Investigator were visiting the islands to conduct research into the concentration of iron in Antarctic waters.

“We witnessed the lava descending Big Ben as it interacted dramatically with the snow and ice cover of the mountain,” said ANU volcanologist Professor Richard Arculus, who witnessed the eruption first hand.

Popocatépetl volcano (Mexico) update: moderately strong explosion, recent lava dome destroyed

The volcano had a relatively strong explosion yesterday evening at 20:31 local time.

It produced a 2 km ash column and ejected incandescent fragments that landed in to up to 3.5 km distance on the eastern and southeastern flanks, igniting some bush fires on the upper slopes of the volcano.

An overflight on Saturday with the help of a Federal Police helicopter showed that yet another cycle of dome growth and destruction has recently completed at El Popo (and a new one is about to begin): during their survey, CENAPRED scientists observed that the most recent lava dome, which had been growing since January and lately contained up to approx. 2 million cubic meters of lava, was missing, obviously destroyed by the volcano’s recent series of explosions. In its place, a new inner crater approx. 50 m deep and 325 m in diameter was seen. Likely, the near future will see another dome growing inside it.

Scientists monitoring Mt Ruapehu after volcano displays signs of elevated activity

HEATING UP: Temperatures on Mt Ruapehu have been increasing in recent weeks.

An aerial observation was being conducted over Mt Ruapehu yesterday after temperatures in the active volcano’s bubbling Crater Lake rose to the hottest on record.

On Saturday, a tourist flight over the Crater Lake observed “vigorous steaming” at the lake and disturbance of the surface itself with “upwelling bubbles”.

This sort of activity had not been seen in years while Crown research institute GNS Science said a temperature of 44C was “the hottest lake temperature we have recorded since the new lake was established post-2000”.

A flurry of volcanic earthquakes reported on Tuesday had now stopped. However, the seismic network at Ruapehu continues to record volcanic tremors.

GNS volcanologist Brad Scott had been closely monitoring activity overnight on Saturday and said there had been only more tremor and an insignificant change in lake temperature of around 0.3 of a degree.

“There has been little or no change from yesterday – activity has been dominated by volcanic tremors with no distinct or individual volcanic earthquakes.”

But the elevated temperatures did not necessarily mean an eruption was imminent.

“In fact, if you track back through the record, sometimes it has erupted from cold lake temperatures. This is what makes it difficult for us, as there’s no fixed pattern.

“In the end, it’s an active volcano and we should always pay respect to it.”

The developments weren’t enough to upgrade Mt Ruapehu’s volcanic alert level, which remained at 1.

The last time it erupted was on September 25, 2007, causing a 7 minute earthquake, two lahars and flying rocks – one of which crushed the leg of primary school teacher William Pike when it landed on Dome Shelter near the crater.

Since then, there have been warnings in 2008, 2011, 2012 and this year – none of which resulted in another major event.

Meanwhile, unrest was continuing at the volcano at White Island, where a minor eruption occurred last month. While there hadn’t been another event as large, Mr Scott said, small geysering at the crater and a series of volcanic earthquakes indicated there was still “significant unrest” at the offshore volcano in the Bay of Plenty.- Wanganui Chronicle
