Indonesia's Mount Lewotobi Laki-Laki erupts, forcing airport to close

mmmmm
A highly active volcano in eastern Indonesia erupted several times on Friday (Jun 5), spewing towering ash columns into the sky and forcing a local airport to close, authorities said.

Mount Lewotobi Laki-Laki on Flores Island erupted at 11.15am, sending volcanic material 2.5km into the air, the national volcanology agency said in a statement.

It came after several other eruptions earlier on Friday.

Lewotobi Laki-Laki falls under Indonesia's second-highest alert level for volcanic activity, with a 5km exclusion zone in force around its crater.

Hawaii's Kilauea volcano begins 48th episode

mmmmm
Hawaii's Kilauea volcano experienced its latest eruption episode Monday.

On Monday, June 1, at 4:40 a.m., Episode 48 of the ongoing Halemaʻumaʻu eruption at the summit of Kilauea began. The north vent is particularly active this episode, with occasional overflows from the south vent, according to the Hawaiian Volcano Observatory.

Around 6:30 a.m., officials observed fountaining over 500 to 650 feet above the north vent. The plume from this eruption is currently reaching 24,000 feet above sea level.

The National Weather Service said tephra, which is material that emerges from a volcano during an eruption, could be dispersed to the north based on the winds from the south at 10,000 to 20,000 feet above sea level.

Mount Marapi eruption ejects column of ash 2,000 meters high in West Sumatra, Indonesia

mmmmm
Indonesia's Mount Marapi spews ash column 2 kilometers into sky
The Geological Agency of the Ministry of Energy and Mineral Resources (ESDM) reported that Mount Marapi in West Sumatra Province had erupted by launching a volcanic ash column of approximately 2,000 meters above the peak.

The Acting Head of the Geological Agency, Lana Saria, in his statement in Jakarta, Saturday, said that the volcanic activity of the volcano with a height of around 4,891 meters above sea level was recorded at 08.42 WIB this morning.

"The observed ash column is gray with a thick intensity leaning towards the northeast. This eruption was recorded on the seismogram with a maximum amplitude of 30 mm and a temporary duration of one minute 25 seconds," he said.

New geyser is disrupting life in a small community in Michoacán, Mexico

mmmmm
Water burst forth some 15 meters from this backyard of a Michoacán farmer's house before subsiding, as geysers tend to do temporarily. Whether the phenomenon was a true geyser will be determined by scientific observation.
A suspected geyser that burst from the pig pens and backyard of a small Mexican farm this week has prompted evacuations, a school closure and a multi-agency scientific response, according to state and federal officials.

The hydrothermal eruption began overnight Monday in the rural community of El Salitre, about 135 kilometers west of Morelia, the capital of the west-central state of Michoacán.

Water, mud and gases began spewing from "the middle of pig pens on a small family farm," according to authorities.

As of late Wednesday morning, the geyser-like phenomenon was still active, though in a reduced, bubbling-mud state with constant gas emissions rather than a jet, according to Mi Morelia.

Earlier, authorities had reported an initial spout of about 15 meters, which subsided to eight meters.

An unknown number of pigs "died as the result of the eruption," according to N+, the news division of TelevisaUnivision.

Popocatépetl volcano erupts explosively in Mexico

mmmmm
This Thursday, May 28, the Popocatépetl volcano once again drew the attention of much of the country , as monitoring cameras captured the exact moment when Don Goyo had an explosive eruption that generated a column of smoke and gases kilometers long during the afternoon of this day.

It was through the different social media platforms that images of the enormous plume of smoke that came out of the crater of one of the most important volcanoes in the Mexican Republic began to be shared.

As can be seen in the images shared on different social media accounts, the fumarole of the Popocatépetl volcano after the explosive eruption carried gases and columns of smoke towards the southeast area of ​​Don Goyo.

The images that were shared clearly show the exact moment the explosion occurred , which left one of the most shocking images of the week in the central region of the Mexican Republic .

Meteor fireball seen over erupting Mayon Volcano in the Philippines on May 25

nnnnnn
A meteor was recorded passing over the slopes of Mayon Volcano on Monday evening, May 25, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).

Phivolcs said its Ligñon Hill IP Camera in Legazpi City captured the meteor at around 10:33 p.m., but noted that it disintegrated while still in the atmosphere and did not reach the slopes of Mayon.

At the time of the sighting, the active volcano in Albay was on its 140th consecutive day of effusive eruption, marked by the slow outflow of lava and intermittent pyroclastic density currents.

Earlier in the evening, the volcano generated lava collapse-fed pyroclastic density currents (PDCs), or "uson," along the Mi-isi and Basud gullies, as well as minor strombolian activity, which refers to short explosive bursts that eject glowing volcanic material and produce brief lava fountains.

New research from the University of St Andrews has precisely dated an eruption from Newberry Volcano and discovered that its ash spread more than 5,000 km across the globe, far further than previously thought for an eruption of its size.

Published in Quaternary Science Reviews, researchers identified ash particles from the Newberry Pumice eruption of Newberry Volcano (Oregon, U.S.) in a Greenland ice core by geochemical fingerprinting — matching the chemical elements in the far-flung ash particles to volcanic deposits of the Newberry Pumice ash from its most recent "Big Obsidian" eruptive period.

Previous dates had narrowed the timing of the eruption to an approximate 140-year window around the turn of the 7th Century AD. Finding the ash in the ice allowed researchers to pinpoint the timing of the Newberry Pumice eruption to within two years of 686 AD, due to the very precise age models that have been developed for Greenland ice cores.

Comment: The Dark Age was exacerbated not only by volcanic explosions: 536 AD, the year the sky went dark

No tsunami is expected following a magnitude 6.0 earthquake that occurred about seven miles to the east-southeast of Honaunau in the South Kona area of Hawaii Island.

According to the U.S. Geological Survey, the earthquake occurred at 9:46 p.m. It was centered about 3.7 miles east-southeast of the Honaunau-Napoopoo area along the western flank of Mauna Loa, at a depth of 14 miles.

The Pacific Tsunami Warning Center said no tsunami was generated by the earthquake.

A second, weaker magnitude 3.2 earthquake occurred six minutes later, just to the northwest of the first about 13 miles beneath the surface.

Campi Flegrei, a volcanic caldera west of Naples, is speeding toward a transition within the next decade, a new study suggests, but researchers can't yet say whether that transition will be an eruption or some other change in the volcano's internal plumbing.

The caldera, also known as the Phlegraean Fields, is home to about 500,000 people who would be at risk in the event of an eruption. The caldera stretches about 9 miles (15 kilometers) in diameter and formed in a massive eruption 40,000 years ago. Other, smaller eruptions have happened since, including an explosive one in 1528 that built Monte Nuovo, a 433-foot (132 meters) cinder cone.

"Our paper identifies when the system is likely to reach a breaking point, but it cannot determine what will happen at that breaking point with the current data," said study first author Davide Zaccagnino, a postdoctoral researcher who studies geological hazards at the Southern University of Science and Technology in Guangdong, China.

Ash from Bezymianny volcano eruption covers 2 villages in Kamchatka, Russia - ash column of up to 10 km high

mmmmm
In the Ust-Kamchatsky district in the village of Mayskoye and the settlement of Kozyrevsk fell out Ash from the eruption of Bezymyanny volcano. Ash column burst out to a height of up to 10 km with the volcano's height being 3020 meters.

Volcanologists have assigned the volcano a "red" hazard rating, meaning it poses a hazard to air travel. Emergency services have not received any complaints or calls from residents. There was minor ash fall in Kozyrevsk, and about 3 mm in Maysky.

Volcanic ash is dangerous to humans. Emergency workers recommend staying indoors and closing windows and doors whenever possible. Inhaling ash can cause allergic reactions, so wear respirators and headbands soaked in a soda solution. It's best to cover equipment with plastic and avoid using it until the ashfall subsides. Bringing ash into your home, including on your clothing, is not recommended. When cleaning ash from your home, wear a mask and goggles.

In the administration of the Ust-Kamchatsky District announced theThey will distribute free masks in the villages of Krutoberegovo and Mayskoye, the settlements of Kozyrevsk, Klyuchi, and Ust-Kamchatsk.

Previous major ashfall passed In Kamchatka three years ago, after the Shiveluch volcano eruption, the ash layer on the snow reached several centimeters.
