Petropavlovsk-Kamchatsky city of 180,000 is just 26 km from 'waking' Avachinsky on Pacific's ring of fire.
Avachinsky - also known as Avacha - and its big sister volcano Koryaksky tower over the Kamchatka capital of Petropavlovsk-Kamchatsky, giving it one of the most spectacular city views anywhere in the world.

Recent days have seen signs of activity on stratovolcano Avachinsky - 2,741 metres (8,993 ft) - prompting warnings to locals and tourists to stay away.

Vulcanarium website warned: 'Today, December 9, early in the morning, the first outbreaks were recorded in the crater of the volcano.

'Avacha has high gas contamination, you cannot get to the top.'

White Island Volcano erupts in New Zealand: At least five people dead & cruise ship tourists missing - UPDATE

White Island volcano, New Zealand

White Island volcano, New Zealand
A volcano erupted in New Zealand on Monday leaving at least one dead and seven tourists critically injured. Police said there could be more fatalities. 23 people have been transported to shore and over 27 remain on the island.

"We are working to confirm the numbers involved. At this stage, it is too dangerous for police and rescue services to go to the island. However, we continue to assess the conditions which would allow us to go onto the island", Police Deputy Commissioner John Tims said.

CEO of the New Zealand Cruise Association Kevin O'Sullivan confirmed that 30 to 38 of the victims are passengers of the cruise ship Ovation of the Seas.

The eruption began about 2:11 p.m. local time (0111 GMT) on White Island, about 50 kilometres from the east coast of North Island, authorities said, sending up smoke visible from the mainland.

Police is working with National Emergency Management Agency to coordinate the search and rescue operation.

Comment: Just a day earlier, New Zealand experienced a record in lighting strikes:
In the 24 hours leading up to 7am this morning, 109,000 lightning strikes were recorded over New Zealand and our surrounding waters, with 18,000 over the land.

Previously our records had only seen 44,000 strikes over both land and sea.
Update: New Zealand Herald reports:
At least five people are dead after Whakaari/White Island erupted today, and "a number" of people are still unaccounted for.

National Operation Commander Deputy Commissioner John Tims told a press conference at 9.10pm that New Zealanders and tourists are involved.

A number of the tourists are from the Ovation of the Seas cruise ship, but police cannot confirm nationalities.

Police do not know if there are people on the island alive tonight. The five people dead are people who were taken off the island today. The other 18 rescued all have injuries to some degree.


Smoke and ash rise from Sakurajima Volcano in Japan following series of eruptions

Sakurajima Volcano

Sakurajima Volcano
Smoke was seen rising from the Sakurajima Volcano in Kagoshima, Japan, on November 28, with the area impacted by a number of days of volcanic activity.

In total, "nine eruptions and eight explosions were detected between November 25 and 29 November 2019," according to VolcanoDiscovery.com.

The same report, which cites the Japanese Meteorological Agency, stated that the plume of smoke from the volcano reached 14,400-feet in altitude, resulting in a large amount of sulfur dioxide being released. The Japanese Meteorological Agency forecasted ashfall in the area on the same date.

The dramatic scene comes three weeks after the largest explosion at the volcano in three years.

Volcano in Guatemala erupts - 3 explosions an hour

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 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.
