Massive plumes of white smoke are rising kilometres over a remote spot in the Pacific after an underwater volcano erupted earlier this week, and it could potentially mean the arrival of a brand new island.

The eruption at Matis Shoal, a submarine volcano around halfway between the islands of Kao and Late in Tonga, was first noticed on Tuesday when a pilot with the Real Tonga airline flew over the area and alerted ground control to white columns of steam rising to about 5000 metres elevation.

GeoNet and the Wellington Volcanic Ash Advisory Centre, a department of Metservice, have been monitoring the situation, but say there is currently no risk to flights in the area.

Eruption column and pyroclastic flow at Shiveluch volcano

Eruption column and pyroclastic flow at Shiveluch volcano on Oct 2nd
A moderately large explosive eruption occurred on Shiveluch volcano earlier this morning, producing an ash plume that rose to 30,000 ft (10 km) altitude and a pyroclastic flow that traveled several km to the west from the active dome.

The eruption was likely a combination of explosion at the lava dome and a partial collapse of fresh material from the active part of the dome in its upper NE sector:


Volcano erupts in Costa Rica, prompting park closure

Volcano erupts
The eruption Monday of Poás Volcano in Costa Rica has prompted officials to temporarily close the popular tourist attraction because of a "high probability" of more eruptions.

The dawn eruption, captured on video by the Volcanological and Seismological Observatory of Costa Rica (OVSICORI), sent a column of ash more than a mile above the 8,885-foot volcano.

Poás Volcano National Park, located 29 miles northwest of the Costa Rican capital of San Jose, remained closed Tuesday and a reopening date had not been announced at the time of this post.

Papua New Guinea's volatile Ulawun volcano erupted early on Tuesday, sending a column of red lava shooting up into the sky and forcing the evacuation of recently returned residents.

Mount Ulawun, situated on the remote Bismarck Archipelago chain, displaced between 7 000 and 13 000 people from their homes when it last erupted in June.

Seismic activity started at midday on Monday before the volcano erupted at about 04:30 on Tuesday, according to Rabaul Volcano Observatory assistant director Ima Itikarai.

"It was noiseless and in the dark just before dawn; the eruption was visible (with) a distinct shard (of) red incandescent glow shooting up less than 100m from the base," he told AFP.
