The earthquake struck 25 kilometres south of Gisborne, but was felt across the island just one day after a deadly volcano eruption on White Island
A strong 5.3-magnitude quake shook New Zealand's North Island, just hours after a lethal volcanic eruption killed five and left eight others missing. No damage or casualties have been reported following the latest tremor.

The quake struck at a shallow depth of some 25km (15 miles) around Gisborne on Tuesday, about 150km (93 miles) south of the recently erupted submarine volcano on White Island.

While local news reports said the seism could be felt in neighboring towns - including Cambridge, Hunterville, Dannevirke and Wellington - there are currently no reports of damage or injuries, nor any danger of a tsunami, according to Gisborne Civil Defense Manager Wiremu Tamati.

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.'

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

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 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.

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.
