Eruption at Kerinci on 28 Sep 2018
Indonesia's highest volcano seems to have increased during the past week.

Following a moderately strong vulcanian-type explosion on 28 Sep, several other smaller to moderate explosions and ash emissions have occurred.

During the past days, Darwin VAAC report ash plumes from the volcano that rose to an altitude of 4.3 km (14,000 ft) a.s.l. and drifted SW and W.

Kerinci is one of Indonesia's most active volcano and has been the site of intermittent, mild explosive activity for years. Most of its usually smaller explosions go unnoticed.

High levels of seismic activity reported at Grenada's Kick 'em Jenny underwater volcano

The University of the West Indies Seismic Research Center (UWI SRC) on Tuesday reported there have been high levels of seismic activity at the Kick 'em Jenny underwater volcano in the past few days.

Grenada's National Disaster Management Agency (NaDMA) said in a statement that since the episode began on the afternoon of September 30, several events have taken place. The largest of those occurred on Monday at 3:24 a.m., 3:35 a.m. and 3:56 a.m. of magnitudes 3.5, 3.5 and 3.3 respectively.

The UWI SRC said it is currently analysing the data and will update further after complete processing,

NaDMA has informed marine interests and the general public that the threat level at the volcano, located about five miles north of Grenada, remains at yellow, so the exclusion zone of 1.5 kilometres must continue to be observed.

The yellow alert means "the volcano is restless: seismicity and/or fumarolic activity are above the historical level, or other unusual activity has been observed, or can be expected without warning".

Volcano erupts on Indonesia's Sulawesi days after fatal earthquake & tsunami

Natural disasters continue to plague Indonesia, with the Mount Soputan volcano erupting on the island of Sulawesi just days after a devastating tsunami, triggered by a massive earthquake, struck the island, killing hundreds.

After months of increased seismic activity, the Soputan volcano finally blew off steam on Wednesday morning, sending an ash column as high as 4,000 meters into the air. Ash plumes are now moving in the west and northwest direction, with an alert level III issued for the active volcano.

Communities residing within a 6.5 km radius of the summit are being advised to stay clear of the area due to potential threats of lava flow and dangers from the ash clouds. Locals who chose to stay in the vicinity of Soputan are being instructed to wear face masks to cover the nose and mouth, in order to avoid respiratory problems.

So far there have been no reports of casualties or damage on the island, already heavily devastated by last Friday's quake and tsunami which claimed the lives of over 1,300 people.



Eruption and ash emission are continuing while the Volcano Observatory Notice for Aviation (VONA) has, meanwhile, been updated to the color code Orange by the Ministry of Energy and Mineral Resources.

Popocatépetl Volcano spews ash on Mexico City

Popocatepetl volcano

Popocatepetl volcano
Ash spewing from the Popocatepetl volcano has reached the southern neighborhoods of Mexico's capital.

The National Center for Disaster Prevention warned Mexicans on Saturday to stay away from the volcano after activity picked up in the crater and it registered 183 emissions of gas and ash over 24 hours.

The center was monitoring multiple rumblings and tremors. Images on social media showed thin layers of ash coating car windshields in neighborhoods of Mexico City such as Xochimilco.

Geophysicists have noticed an increase in activity at the volcano that sits 45 miles (72 kilometers) southeast of the capital since a 7.1-magnitude earthquake rocked central Mexico in September 2017. The volcano known as "Don Goyo" has been active since 1994.

Turrialba Volcano shows high ash emission in Costa Rica

Turrialba Volcano

Turrialba Volcano
The Turrialba volcano has shown a strong ash emanation on Monday, after the strong eruptions of the past 12 hours on this Costa Rican hill in the province of Cartago, some 70 kilometers southeast of San Jose.

A report from the Vulcanological and Seismological Observatory of Costa Rica (Ovsicori) states the Turrialba began its emanations at 22:00 local time this Sunday and still remains, when the column rises to about 500 meters above the crater.

At dawn, Turrialba Volcano is covered with a great amount of ash emanation, which is blowed by the wind towards the northeast with influence on Guapiles, Pocora and surrounding places', in the direction of the Caribbean coast, indicates Ovsicori, belonging to the National University.

The eruptions of the 3,340-meter-high colossus -the second highest in the country after Irazu, measuring 3,432 meters- have been active since January 2010. They generally affect the Central Valley, home to 60 percent of the country's five million inhabitants.

Arenal, Irazu, Poas, Rincon de la Vieja and Turrialba are the five active volcanoes out of the 150 existing in Costa Rica, according to the most recent geological data.

One of the cauldrons in the ice cap of Vatnajökull above the monster volcano Bárðarbunga.
A sharp earthquake swarm was detected in the Bárðarbunga caldera early morning today, Monday. A 3.0 magnitude quake, with an epicenter 7.6 km (4.7 mi) east of Bárðarbunga peak, on the eastern edge of the caldera of the central volcano, at a depth of 3.4 km (2.1 miles) was detected at 6:09 in the morning. Half a dozen smaller aftershocks were detected.

The Bárðarbunga system has been showing increasing levels of activity for the past year or so, following the 2014-15 Holuhraun eruption at the northern edge of the system.

Hot spots at Barren Island volcano suggesting lava flows from the crater on the northern flank of the cone
A new eruption seems to be going on at the remote island (the only active volcano of India): since around 25 Sep, a strong thermal signal has been visible on satellite data and suggests lava flows on the north flank of the active cone, probably reaching the NW coast.

Anak Krakatau erupted 44 times
With the 45+ eruptions at Krakatoa in Indonesia over the weekend and the Minbu Mud Volcanoes in Myanmar starting to uptick, makes you wonder what is happening under the plate and if it is on regular cycles that can be mapped because volcanic eruptions are one event that occurs during Grand Solar Minimums.

Krakatoa volcano stirs to life

The volcanic island of Krakatau (previously called Krakatoa) is situated in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The name is also used for the surrounding island group comprising the remnants of a much larger island of three volcanic peaks which was obliterated in a cataclysmic 1883 eruption.

In 1927, a new island, Anak Krakatau, or "Child of Krakatoa", emerged from the caldera formed in 1883 and is the current location of eruptive activity.

In the NASA photos below, you can see some stunning images of the volcano as it's been stirring to life again
