An intermittent smoke eruption towering to 15,000-17000ft above the summit of the Metis Shoal Volcano, Ha’apai, this morning, has an increased likelihood of an eruption, with an aviation VONA alert now increased to Orange, the Tonga Meteorological Service advised at 10:20am.

Metis Shoal submarine volcano is located near Kao in Tonga’s Ha’apai Group, and is famous for its previous pumice eruptions that have created large pumice rafts.

Real Tonga pilots flying between Tongatapu and Vava’u on flights R4801 and R4802 this morning observed the intermittent smoke eruption, with continuous white plumes of wispy ash cloud.

“We just reconfirmed with the pilot on his way back that 25-30nm north of Kao, towering smoke erupting up to 15,000-17,000ft,” Tonga Met reported this morning, before upgrading an earlier Yellow alert to Orange.

Tonga Met Director, ‘Ofa Fa’anunu said that so far there had been no earthquakes detected in the area of the smoke eruption.

“The Town Officer of Fotuha’a Island, Sifa Fuakolo, first reported to us 8:30pm last night but [we] couldn’t verify till this morning’s Real Tonga flight.”

He said Tonga Met will issue a new Volcano Observatory Notice for Aviation (VONA) this evening, after domestic flights come in and any other shipping reports or observations are received.

#MountMerapi #Volcano erupts in #Indonesia’s #Java island, triggering #Orange #Aviation warning

Orange Alert

Mount Merapi, an active volcano in Indonesia’s Java island, erupted on Monday afternoon, spewing a column of ash up to 3 km high and forcing the authority to issue a warning for planes, national volcanology agency said.

The volcano located on the border of Central Java and Yogyakarta provinces erupted at 4:31 p.m. Jakarta time with hot ash from the crater, and the wind blew the ash towards southwest, the agency said in a statement.

A volcano observatory notice for aviation was issued by the agency with the status of orange, indicating the possibility of a further eruption.

No-go zone has been put in place for in a radius of 3 km from the crater. People living near the volcano were warned of the possibility of rains of ash.

Mount Merapi is one of Indonesia’s 129 active volcanoes and has regularly erupted since 1948.

The volcano is located about 28 km north of Yogyakarta city and thousands of people live on the flanks of the volcano.

Alert Level Raised To Orange At #Villarrica #Volcano In Central #Chile

Orange Alert Raised

Sernageomin has raised the alert level to Orange for the first time since 2015 due to escalating seismic tremor and a more turbulent lava lake (present in some form since late 2014). Although fairly unlikely, it is possible that a repeat of the March 2015 paroxysmal event could soon occur if there is a similar trend in activity. An exclusion zone of 2km is in force.

#Eruption at #AsamayamaVolcano, Alert Level Raised #Japan

A small eruption was observed Wednesday on Mt. Asama in eastern Japan, prompting the volcanic alert level to be raised from 1 to 3 on a scale that goes up to 5, while there were no immediate reports of injuries, the weather agency and local authorities said.

The eruption occurred at 10:08 p.m. near the crater of the 2,568-meter-high volcano, with smoke reaching about 1,800 meters above the mountain, according to the Japan Meteorological Agency. The elevated alert level means people should not approach the mountain.

The agency warned of possible flying rocks and pyroclastic flows within about a 4-km radius of the crater.

At a press conference early Thursday, the agency said no pyroclastic flows had occurred in the latest eruption, while urging people to stay out of harm’s way by following instructions from local authorities.

The agency said the volcano spewed ash deposits as far as 200 meters from the crater, which is situated on the border between Gunma and Nagano Prefectures. The eruption lasted about 20 minutes.

Gunma’s Naganohara town office advised 28 people at a campsite at the foot of the mountain to evacuate. The site is located within the 4-km radius.

The town of Karuizawa in Nagano closed the starting points of two trails up Mt. Asama, located about 140 kilometers northwest of Tokyo.

Volcanic ash could fall on the three prefectures of Gunma, Nagano and Niigata, according to the agency.

The government set up a liaison unit at the crisis management center of the prime minister’s office after the eruption.

In June 2015, Mt. Asama experienced a small-scale eruption and the agency lowered the alert level from 2 to 1 in August last year.

Large #Ash #Eruption At #UlawunVolcano In #NewBritain, #PapuaNewGuinea

Unrest has once again escalated and a new phase of major eruptive activity occurred between around 10:00 and 11:00 UTC today, sending a mushroom cloud to 19km, as in the VEI 4 eruption in June. This event appears to have been smaller and has now ended- satellite imagery shows the ash cloud drifting away from the volcano. The Rabaul Volcano Observatory sent out an alert of increasing seismicity yesterday, with more advanced warning than in June, which reflects the smaller size of this event.
