The Semeru volcano in Indonesia's East Java province erupted five times on Friday, spewing volcanic ash up to 900 meters over its peak, according to the Center for Volcanology and Geological Hazard Mitigation.

"The first eruption was at 6.29 a.m. local time, with a column of white to grey ash as high as 500 meters heading to the southwest," said Semeru Volcano Monitoring Post officer Liswanto, Xinhua news agency reported.

The second eruption occurred at 6.50 a.m. local time, launching ash as high as 600 meters above its peak, while the third eruption occurred at 7.28 a.m. local time, releasing an ash column as high as 700 meters.

Volcanic ash was thrown up to 500 meters in the fourth eruption and 900 meters in the fifth, which happened at 7.57 a.m. and 8.05 a.m. local time, respectively.

Authorities have urged people to stay out of the danger zone within a 5 km radius and 13 km southeast of the crater to prevent harm from hot clouds, lava flows and lahars.

People are advised to avoid rivers that originate from the Semeru crater against possible cold lava flows.

Concepción Volcano, the largest on Ometepe Island, launched a huge column of smoke and ash, while residents heard rumbles. Much of the island received volcanic ash from the crater, according to reports on social media.

The explosions from Concepción, which reaches a height of 1610 meters, began shortly after two in the afternoon, according to authorities who activated an alert system on Ometepe Island.

On social media, inhabitants of the paradisiacal island —which is home to the small cities of Altagracia and Moyogalpa— as well as tourists, shared videos and photos showing a large column of smoke rising into the sky, and ash visible in the environment.

"We can see how the Moyogalpa pier is covered in ash. Since I've lived on the island, I've never felt this pure adrenaline here, I had never seen it," a user on TikTok recounted, showing a video at the island's main port.

NNNNNNNNNNN
In Azerbaijan, the Bozdag-Guzdek mud volcano has erupted for the first time in 15 years. The mud eruption lasted nine minutes and produced seismic signals that were detected by the country's Republican Seismic Survey Center. The eruption occurred on May 13 at 2:13 a.m. local time.

The mud volcano has a vent 3.5 kilometers deep and is located near the Sangachal oil field. It is one of the largest oil and gas producing areas in Azerbaijan and is located near the city of Baku on the Absheron Peninsula. Consequently, the mud volcano has nothing to do with real volcanism or magmatism: its eruptions are linked to methane gas, of which there is more than enough in the area. This is also reflected in the high number of mud volcanoes, which promote organic compounds. There are over 700 known mud volcanoes in the world, half of which are in Azerbaijan.

A volcano in eastern Indonesia erupted on Wednesday and spewed an ash tower almost a mile into the sky, prompting officials to raise an alert level to the second-highest and warn people to keep away.

Mount Ibu, located on the island of Halmahera in North Maluku province, erupted at 11:11 am local time (0211 GMT) and sent a thick column of dark smoke and ash above the peak.

The volcano spewed an ash tower 1.5 kilometres (0.93 miles) above the peak, Indonesia's volcanology agency (PVMBG) said.

"Based on the results of visual and instrumental monitoring... Mount Ibu's activity level has been raised from level two to level three" of a four-tiered system, said PVMBG chief Hendra Gunawan in a statement Wednesday.

Authorities formed an exclusion zone between three and five kilometres around the volcano's crater.


Comment: Update May 13

Indiatvnews.com reports:
Indonesia's Ibu volcano erupted on Monday morning, spewing thick columns of grey ash several kilometres into the sky, the country's volcanology agency said. The volcano on the remote island of Halmahera erupted at 9.12 am for about five minutes, projecting ash into the sky as high as 5 km (3.1 miles), officials said, after a smaller eruption was recorded as Friday.

The alert status of the volcano remains at the second-highest level, according to Hendra Gunawan, head of Indonesia's Volcanology and Geological Hazard Mitigation Centre. All activities within a five-kilometre radius of the volcano were prohibited, he added. "If it starts to rain ash, we recommend people who are near the volcano to wear a mask and glasses," Hendra said.

Footage of the eruption shared by the centre showed clouds of grey ash billowing from the crater. The official said a booming noise was also heard. No evacuation of residents has been reported so far.

Attention

Odd earthquake swarm in Central Europe hints at magma activity in region far from tectonic boundary

© honza28683 via Getty ImagesThough it's nowhere near a tectonic plate boundary, the Vogtland region is known for its earthquake swarms.
An odd earthquake swarm on the border of Germany and the Czech Republic may hint at magma moving deep below the surface.

The quakes are in Vogtland, a region known for regular, low-level earthquake swarms. These swarms tend to last several weeks and lead to mostly mild shaking. The largest known quakes from the area are around magnitude 4.5, said Torsten Dahm, a geophysicist at the GFZ German Research Centre for Geosciences who's leading a project monitoring this region.

Dahm and his colleagues recently finished deploying a new network of seismometers installed in boreholes in the Vogtland area. These seismometers captured a late-March earthquake swarm unlike others seen in the area — the center of the swarm jumped 9 miles (15 kilometers) to the north, compared with previous swarms. And instead of occurring on a vertical fault line underground, it seems to have taken place on a near-horizontal underground structure.

Comment: There's certainly been a significant number of 'surprising' and 'unusual' seismic and volcanic reports in recent years, and it seems reasonable to suppose that this signals an uptick in activity: Volcanoes, Earthquakes And The 3,600 Year Comet Cycle

Authorities had warned the threat from the volcano was not over after it erupted more than half a dozen times this month, sparking the evacuation of more than 6,000 people.

Ruang, located in Indonesia's outermost region of North Sulawesi province, erupted at around 01:15 am local time (1715 GMT Monday) and twice more Tuesday morning, the volcanology agency said in a statement.

The volcano sent a tower of ash more than five kilometres (3.1 miles) into the sky, it said.

The agency also re-instated a six-kilometre (3.7-mile) exclusion zone and said locals should be aware of "the potential for ejections of incandescent rocks, hot clouds and tsunamis due to eruption material entering the sea".

Nearly 800 individuals have been evacuated because of the eruption of the Ruang volcano, located on the Sangihe Islands in North Sulawesi, Indonesia. It's part of the Pacific Ring of Fire, which is known for its frequent volcanic eruptions and seismic activity.

The eruptions at the Ruang volcano occurred multiple times since Tuesday (Apr 16). As the magma rose to the surface and erupted, it produced various volcanic materials, including lava flows and ash clouds. The delicate situation prompted the authorities to elevate the alert level to the second highest.

Heruningtyas Desi Purnamasari from Indonesia's Center for Volcanology and Geological Hazard Mitigation (PVMBG) reportedly told Reuters that recent earthquakes on the island triggered the eruptions. This resulted in the emission of dangerous "explosive hot clouds" reaching heights of 1.8 km.

"We must clear the island because we anticipate there could be more eruptions. No activity is allowed within four kilometres from the crater," Purnamasari said.

Taal Volcano in Batangas exhibited increased volcanic activity with five phreatic eruptions occurring within a 24-hour period, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).

In its latest bulletin, Phivolcs reported that between 12 a.m. Friday and 12 a.m. Saturday, Taal experienced five phreatic eruptions, with one event lasting for 13 minutes.

A phreatic eruption, according to Phivolcs, is a steam-driven explosion that occurs when water, either below the ground or on the surface, is heated by magma, lava, hot rocks, or fresh volcanic deposits.

During the same monitoring period, a total of fifteen volcanic earthquakes, including six volcanic tremors, with durations ranging from two to four minutes each, were recorded.

Plumes reaching heights of up to 2,400 meters were observed drifting southwest and northwest.
