Popocatépetl volcano (Mexico): Elevated activity, 13 explosions during 24 hours

The level of activity of the volcano remains high, with frequent moderate to strong explosions, which often produce ash plumes of several kilometers height and eject lava bombs and blocks to up to approx. 1 km distance from the crater.

In its latest report a few hours ago, CENAPRED reported that during the most recent 24 hour interval, the volcano produced 162 exhalations (passive emissions of steam, gas and low amounts of ash), 13 explosions at 00:34, 01:00, 01:45 (image 1), 01:47, 02:08, 02:27, 02:33, 03: 20, 03:39, 05:56, 06:44, 08:10 and 08:27 local time, as well as 711 minutes of tremor.

Clearly, the flux of magma currently rising inside the volcano is elevated compared to the average of the pat years. This could calm down gradually again or increase further, something impossible to predict. The alert level remains unchanged at "Yellow Phase 2".

3km exclusion zone after Mt Merapi spews lava in Indonesia

Indonesian authorities banned residents and trekkers from doing activities within 3 kilometers from the summit of Mount Merapi as the volcano located between Central Java and Yogyakarta provinces spewed hot lava on Wednesday morning.

Mount Merapi spewed the hot lava as far as 950 meters, heading to upstream of Gendol River in the two provinces' border area at 04:52 Jakarta time, Spokesperson of Indonesia's National Disaster Management Agency (BNPB) Agus Wibowo said.

The hot lava emission from the Merapi crater lasted around 95 seconds was recorded to have maximum amplitude of 50 millimeters, he added.

The volcano that stands at 2,968 meters tall above the sea level has been showing significant escalation of volcanic activities in the last several days with 10 intense land tremors were recorded in various degrees on Saturday.

Volcano in Russian far east emits ash to 5 km

The Karymsky volcano on the Kamchatka Peninsula in Russia's Far East emitted ash to an altitude of 5 km Wednesday, according to the Institute of Volcanology and Seismology of the Far Eastern Branch of the Russian Academy of Sciences.

"A moderate eruptive activity of the volcano continues and ash explosions of up to 6 km could occur at any time," it said in a statement, warning that it could affect low-flying aircraft.

The institute has attributed orange color code to the activity, which under the aviation color code map signifies that a volcano is exhibiting heightened unrest with an increased likelihood of eruption or that a volcanic eruption is underway with either minor ash emission or none at all.

As one of the most active volcanoes on the peninsula, the 1,486-meter-high Karymsky volcano is located 115 km north of Petropavlovsk-Kamchatsky, the administrative center of Kamchatka region.

Piton de la Fournaise volcano (La Réunion Island)

The erupting volcano has entered the fourth day of the eruption on Wednesday, August 14, after activity began after 4pm local time on Sunday.

Since the eruption started, two volcanic fissures split the mountain's east flank wide open, spewing rivers of lava towards the coast.

Aerial pictures of the volcano show bright streams of molten rock slowly making their way towards the coastal highway RN2.

Amateur volcanologists and witnesses to the incredible event were photographed watching the eruption along the same road.

Mexico's majestic Popocatepetl volcano erupted early on Tuesday (August 13) morning, in a dramatic show of ash, water vapour and gas under a canopy of stars.

The dramatic eruption at 5:43 am local time (1143 GMT) spewed ash followed by incandescent rock.

Adapt 2030 Ice Age Report: Underwater volcano eruption & Typhoon Lekima same day Taiwan

At 5:30 am a 6.0 earthquake hit off the Taiwan coast under a stratavolcano beneath Turtle Island (GuiShan Island). Interestingly that seemed to signal an underwater volcanic eruption at the same time Typhoon Lekima neared the island. Is it an Earth - Sun electrical connection? The Ionosphere Map shows nothing unusual but when three typhoons form over the western Pacific and earthquakes are popping off all over the place at he the same time perhaps we should look to the electromagnetic coupling between the Sun and Earth for causation.

Screengrab captured by Jiji Press from a Japan Meteorological Agency surveillance camera on Aug 7, 2019 showing an eruption of Mount Asama in central Japan.

A volcano near Tokyo erupted for the first time in four years, throwing ash and smoke nearly 2km into the sky and sparking warnings not to approach the mountain.

Mount Asama, about 140km northwest of the Japanese capital, exploded overnight and prompted the national meteorological agency to raise its alert level to three out of five, meaning people should avoid the crater.

The agency warned that large rocks and fast-moving flows of hot gas could affect a radius of 4km from the crater and that nearby towns could be hit by smaller rocks and ash depending on prevailing winds.

Video captures spectacular upward lightning display at Guatemala's Volcan de Agua

upward lightning was spotted at Guatemala’s Volcan de Agua

Upward lightning shooting from the top of a mountain has been captured on camera by an amateur photographer.

Alyssa Barrundia, a missionary living in Guatemala, captured the spectacle at Volcan de Agua in the south of the Central American country on Friday.

Ms Barrundia said it was the second time in the past few weeks the striking spectacle had occurred at the volcano, but the first time she had witnessed it personally.

"It was quite spectacular," she told PA.

Papua New Guinea's Ulawun volcano erupts again - ash column rising to colossal 63,000 ft (19.2 km)

Another high-level eruption took place at Ulawun volcano at 10:30 UTC, Aug 03. It follows the ejection to 63,000 feet (19.2km) on June 26 which was the world's first full-scale subplinian eruption since Calbuco, Chile in 2015, which ranked as a VEI 4.

A repeat of that June 26 eruption has just taken place (Aug 03), firing another colossal ash column to 63,000 feet (19.2 km) a.s.l. and comfortably into the stratosphere, according to the Volcanic Ash Advisory Center (VAAC) Darwin,

Particulates ejected to altitudes above 32,800 feet (10 km) have a direct cooling effect on the planet.

This large eruption was preceded by two smaller, though still significant puffs, on Aug 03 — one to 25,000 feet (7.6 km) and the other to 50,000 feet (15.2km). While two powerful ejections have occurred since the 'big one' — both to an estimated 45,000 feet (13.7 km) a.s.l.

This latest eruptive activity looks set to be at least as big as 2000's eruption, which ranked as a VEI 4.

Water discovered in Hawaii's Kilauea volcano could trigger explosive eruptions

In this Thursday, Aug. 1, 2019, aerial photo, a small pond of green water is seen at the lowest point of Kilauea volcano's Halemaʻumaʻu Crater in Hawaii Volcanoes National Park in Hawaii. The discovery is the first time water has been observed in the Big Island crater in recorded history. When lava interacts with water it can cause explosive eruptions, but scientists say it's too soon to know if the pond will cause a violent reaction.

For the first time in recorded history, a pond of water has been discovered inside the summit crater of Hawaii's Kilauea volcano, a development that could signal a shift to a more explosive phase of future eruptions.

After a week of questions about a mysterious green patch at the bottom of the volcano's Halemaumau crater, the former home of a famed lava lake, researchers confirmed the presence of water on Thursday, officials with the U.S. Geological Survey told The Associated Press on Friday.

"The question is what does this mean in the evolution of the volcano?" USGS scientist emeritus Don Swanson said.

Halemaumau has never had water since written observations began, he said, so the pond is unusual.
