The Popocatepetl volcano spews a cloud of ash and steam
Mexico's Popocatepetl volcano erupted twice on Sunday, blasting a column of ash, smoke and gas more than 1.5km into the sky.

A level-two yellow alert warning remains in effect following a second eruption at 6:34pm which sent a column of ash in a north-northwestern direction, following the initial eruption at 5:55am.

Mexican authorities have warned people to stay away from the crater due to the danger of falling "ballistic fragments," and called for extra attention to possible landslides. They also warned locals that ash may cover towns in the surrounding area.

'Mystery' eruption that cooled ancient world traced to El Salvador's Ilopango volcano

The sixth century was a rough time to be alive: Lower-than-average temperatures in the Northern Hemisphere triggered crop failure, famine, and maybe even the onset of bubonic plague. The ultimate culprit, scientists say, were two back-to-back volcanic eruptions — one in 536 C.E. and another around 540 C.E. The first likely happened in Iceland or North America. But the location of the second one has remained a mystery — until now.

Researchers studying ancient deposits from El Salvador's Ilopango volcano knew that a massive eruption had taken place there sometime between the third and sixth centuries. That event, dubbed Tierra Blanca Joven (TBJ), or "white young earth," sent a volcanic plume towering nearly 50 kilometers into the atmosphere.

To better pin down the date of this eruption, the scientists collected slices from three tree trunks embedded in TBJ volcanic ash 25 to 30 kilometers from the present-day lake that covers the caldera (above). The tropical hardwood trees likely died after being engulfed by the searing hot, gale-force winds containing the volcanic gases, ash, and pumice that would have swept outward after the eruption.

Underwater eruption discovered near Fonualei Island, Tonga

Satellite image of the pumice raft on 15 Aug
A new eruption, likely submarine, has occurred (or is still in progress) during the past days west of Vava'u Island in the Tonga archipelago. Its origin volcano is still a bit unclear, but the eruption, evidenced by fresh pumice rafts and steam plumes is most likely from a submarine volcano near or a vent of the small Fonualei volcano.

On 7 Aug, an observer sent us the following report:

"At around 10:40am on Wednesday 7 August, we noticed large clouds of smoke on the horizon at the location of Fonualei volcano. The plume continued to get larger over the next few hours. It seemed to pause and then erupt again."

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

Eruption of Popocatépetl this afternoon
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

lava
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
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 on Reunion Island is erupting for the fourth time this year

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.

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. Check out the Disaster Prediction App.

Weather extremes leading to Global food scarcity and high food prices are here now, and this book describes the expected changes, how to survive & thrive during future challenging times with practical preparations.

Volcano erupts near Tokyo for the first time in 4 years

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.
