#Aviation alert raised to #Orange as #smoke #eruption at #MetisShoalVolcano in #Tonga

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.

Cleveland Volcano, Alaska Alert Level Raised To ORANGE

A small explosion was detected yesterday at 14:57 UTC (05:57 AKST) on seismic and infrasound sensors. A small ash plume was observed heading ENE at an altitude of about 15,000 ft (5 km). 
 
The Alaska Volcano Observatory (AVO) raised the aviation alert level of the volcano to Orange
 
“Explosions from Cleveland typically produce relatively small volcanic ash clouds that dissipate within hours; however, more significant ash emissions are possible. 
 
Cleveland volcano is monitored with a limited real-time seismic network, which inhibits AVO’s ability to detect precursory unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data.”
