Volcano in Guatemala erupts - 3 explosions an hour

Volcano
The Guatemalan Santa Maria volcano has erupted regularly over November, according to INVISUMEH, the country's institute for volcanology. The organisation reported eruptions at the mountain's summit as much as three times per hour over one week.

According to INVISUMEH, explosions surfaced at Santa Maria one to three times per day from November 20 to 26.

The eruptions sent "avalanches" of material descending towards the east, west and southwest flanks of the mountain.

Explosions also coughed out a billowing plume of smoke into the sky, reaching 1,698-2,952 metres above Santa Maria's 12,000-foot height and drifting towards the west and southwest.

Some of this ash fell locally, around El Faro, Santa Maria, and Viejo Palma.

Indonesia's volatile Mount Merapi volcano erupted on Sunday (Nov 17) morning, spewing ash columns up to 1000m into the sky, an official says.

The volcano's eruption occurred at 10:46 am (0346 GMT) Sunday and lasted for 155 seconds, Agus Wibowo, a spokesman for the National Disaster Mitigation Agency (BNPB) said in a statement.

The ash cloud from the eruption was blown west, sprinkling a thin layer of ash on some parts of the village of Banyubiru Dukun, located on the side of the mountain, Wibowo said.

Earthquake swarm raises concerns for big volcanic eruption in Iceland

Earthquakes reported between November 11 and 12. The cluster of red dots corresponds to the Askja swarm.
One of the most active volcanic areas in the world is rumbling again.

Sitting atop the spreading Mid-Atlantic Ridge and one of the planet's hotspots, Iceland is famous for its seismic activity. There are about 130 volcanoes on the island and 30 active volcanic systems.

While volcanic behaviour is difficult to predict, researchers do look for certain seismic signs that indicate an eruption might be imminent. Over the past week, one of Iceland's volcanoes has been attracting attention. On November 6th, an earthquake swarm began at the Askja volcano, located on the eastern part of the island. Since then, roughly 700 earthquakes have been reported at the site, the largest of which was Magnitude 3.4.

Icelandic officials continue to monitor the volcano's activity, although, at the moment, they say the swarm is more likely due to the movement of the continental ridge rather than tremors involving the volcano itself, adding that swarms "occur regularly" around Askja.

Japan's Sakurajima volcano erupts in miles-high plume of ash

Japan's Mount Sakurajima volcano makes largest eruption in 3

Japan's Mount Sakurajima volcano makes largest eruption in 3 years
Japan's Sakurajima volcano shot smoke and ash miles into the sky on Friday in its biggest eruption in more than three years, Kyodo News reported.

The volcano, on the southernmost main island of Kyushu, spewed ash 5.5 km (3.4 miles) high, the first time the ash cloud from an eruption has exceeded 5 km since July 2016, Kyodo said, citing a local meteorological observatory.

The volcano has been highly active, erupting more than 100 times just this year, the report said, adding no damage has been reported so far.

Volcano erupts on island in Kagoshima Prefecture, Japan

Io-dake volcano

Io-dake volcano
Io-dake volcano, on the island of Satsuma Iojima in Kagoshima Prefecture, erupted at 5:35 p.m. on Saturday, the Meteorological Agency said.

The eruption shot plumes of smoke and ash more than 1,000 meters above the crater, and a small amount of ash may fall on the nearby village of Mishima during the night.

The agency has raised the alert level to 2 on a scale of 5 and urged people not to approach the volcano's crater.

The Kagoshima Prefectural Police and Mishima officials said they have not so far confirmed any injures among local residents.

Eruption from Sakurajima on 29 October
Eruptions with continuous pyroclastic flow may continue to occur.

The Japan Meteorological Agency (JMA) recorded two eruptions at the Minamidake summit crater and few volcanic earthquakes.

JMA in cooperation with the JMSDF Air Group confirmed a slight increase of white fumarole from the Showa crater.

Sakurajima has a large amount of volcanic gas (sulfur dioxide) released per day.

Etna volcano erupts again, magnitude 3.3 earthquake also reported

etna
A new eruption of the Etna volcano, accompanied by increased seismic activity, has been detected by specialists of the National Institute of Geophysics and Volcanology of Italy.

According to scientists, there was a magnitude 3.3 earthquake in the province of Catania on the east coast of Sicily on Friday night.

The epicentre was 9 km deep. Felt in Milo, Zafferana Etnea and Sant'Alfio.

There are no reports of casualties and destruction.

Underwater volcano eruption near Tonga could create a brand new island

White smoke plumes above Metis Shoal observed this week.
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.
