Ring of Fire Volcanoes

  • Global Volcanic Activity Heating Up, as Earthquakes Intensify

    The volcanic unrest is increasing around the world.

    There are currently 26 volcanoes erupting around the world and 13 showing enhanced activity. More than 100 earthquakes have been reported near or at volcanic peaks

    The Ring of Fire is currently heating up. As shown in the map above, there are 26 erupting volcanoes (red), 13 showing enhanced signs of explosion (orange) and 45 in unrest.

    Moreover, many earthquakes happen right under or near volcanoes probably announcing movement of magma or magma chamber refill. Yes more than 100 have happened as of 5:00 pm UTC. So that number might also increase in the next hours or so.

    And to better prove what I am saying, look at the maps and ressources I have compiled below:

    Erupting volcanoes

    Popocatépetl (Central Mexico)

    Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 19000 ft (5800 m) altitude or flight level 190 on July 13, 2020.

    Pacaya (Guatemala)

    Effusive eruption of the volcano continues at elevated levels. INSIVUMEH reported that the lava flows on the southwest, northwest and northeast flank (currently about 150 m long) remain active.

    Fuego (Guatemala)

    Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150.

    And here the full report:

    Sangay (Ecuador)

    Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 19000 ft (5800 m) altitude or flight level 190.

    Sabancaya (Peru)

    Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 24000 ft (7300 m) altitude or flight level 240 and is moving at 10 kts in S direction.

  • Major Eruption at Fuego Volcano, Ash to 15,000 Ft, Guatemala

    The Fuego volcano in Guatemala has undergone a major explosion on September 1, 2020, sending a cloud of ash up to 4,700 meters into the sky, after volcanologists have observed an increase in its activity in recent days.

    On Monday, August 31, ongoing strombolian activity caused lava to eject up to 300 meters above the summit of the volcano.

    The eruption sparked “moderate to strong avalanches of material“, and lava reportedly started to descend down the slopes of the volcano.

    Weak to moderate explosions were recorded at six to nine-hour intervals, and an ash plume reached approximately 4,500 to 4,700 meters into the sky.

    Latest Fuego eruptions

    During previous eruptions, the Fuego volcano has caused major devastation.

    The Fuego volcano erupted in June 2018, and it was the volcano’s most violent eruption in four decades.

    Volcanologists believe the ash plume from the eruption propelled up to 33,000ft in the air.

    The eruption killed more than 190 people, making it one of the deadliest volcanic eruptions in Guatemala’s history.

    The Fuego eruption on June 3 affected more than 1.7 million people in three of Guatemala’s states.

  • Major Eruption at Sangay Volcano, Ashfall Turns Night into Day

    The strong eruption of Ecuador’s Sangay volcano on September 20, 2020, has covered tens of thousands of hectares of banana production under a carpet of ash.

    And the explosion ejected so much ash that it turned the day into night across the province of Chimborazo in Ecuador.

    According to exporter association Acorbanec, around 55,000ha of banana plantation have been affected. We estimate that this will lead to a 25% fall in the weekly exportable offer from the affected farms for at least a month,” Richard Salazar told Fruitnet

    Sangay volcano is one of the highest active volcanoes in the world and one of Ecuador’s most active ones. Since June, it has registered very high levels of activity.

    In the last days, the strongest eruption occurred on Sunday morning, with ash continuing to fall until Monday night.

    Juan José Pons, coordinator of a group of four grower-exporter associations known as the banana cluster, said that areas such as Naranjito, El Triunfo, in Guayas, and Mata de Cacao (Babahoyo), Los Ríos, are among the most affected.

    The ash shower interrupts the proper ripening process of the banana, so now the workers in the field will have to do a more meticulous job to avoid the loss of product,” he explained to El Comercio.

    Ecuador exported 260.64m boxes of bananas between January and August 2020, an increase of 8.45 per cent on 2019.

    Shipments to the European Union were up 12.47 per cent compared with the same period last year, while exports to the Middle East, Eastern Europe and Africa increased by 18.99 per cent, 32.75 per cent and 28.10 per cent respectively.

    Meanwhile, explosive activity continues at Sangay volcano. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 21000 ft (6400 m) altitude or flight level 210 on September 24, 2020.

  • Mt. Sinabung Explodes, Ash Cloud Turns Day into Night

    Sinabung volcano in Indonesia had a spectacular eruption on August 10.

    The powerful volcanic eruption sent a thick and dense ash plume approx. 16,400 ft (5,000 m) in the air, changing day into night.

    This is an alert for all of us to avoid red-zone areas near Sinabung,” said Armen Putera, a local official with Indonesia’s Volcanology and Geological Hazard Mitigation Centre.


    Ballistic impacts of volcanic bombs and pyroclastic flows are likely in a 3-km zone around the main crater as well as 4-5 km along the SE and NE flanks.

    Ash turns day into night

    Small communities nearby were coated in a layer of thick ash as at least one village went from day to night in a matter of minutes.

    It was like magic – when the ash came it went from being very bright to dark as night. The village went dark for about 20 minutes.” said Rencana Sitepu, the head of Namanteran village, adding that some of the community’s crops were destroyed by the fallout. Volcanic ash is currently dispersing towards west.

  • Powerful Eruption in Ecuador Covers Cities in Ash

    The eruption of a volcano in Ecuador’s Amazon region left several cities covered in ash on Tuesday.

    The strong eruption fueled concerns of a potential health impact as the South American nation slowly emerges from a brutal coronavirus outbreak.

    The Sangay volcano has had moderate eruptions for over a year that have had little impact because of its remote location, but a recent change in wind patterns has pushed ash toward the coast and affected areas including the largest city, Guayaquil.

    The ash comes out of the Sangay volcano and spreads into the Guayas province, and we see a quantity of ash that is arriving near Guayaquil,” Benjamin Bernard of the Geophysical Institute of Ecuador told reporters, referring to the province where Guayaquil is located.

  • Two Powerful Earthquakes Shake Indonesia, Sinabung Volcano Erupts

    A M6.8 and M6.9 quake has shaken the island of Sumatra, triggering the latest eruption of Sinabung volcano just hours later.

    The two quakes struck off Sumatra’s western coast on Wednesday morning, with an estimated depth of 22km (13 miles) and 26km (16 miles) respectively. The first tremor impacted an area some 144km (89 miles) away from Bengkulu, while the second came closer to the city at 130km (80 miles).

    Though the jolts were strong and shallow, Indonesia’s Meteorology, Climatology, and Geophysical Agency (BMKG) reported that there was “no tsunami potential” in the quakes’ aftermath.

    A few hours after the two big jolts, the Sinabung volcano started erupting again.

    A day before, a M6.6 earthquake hit the Philippines on Tuesday, killing at least one person and damaging roads and buildings.

    It was the strongest earthquake in eight months in the Philippines, which, like Indonesia, lies on the “Ring of Fire,” a seismically active belt of volcanoes circling the Pacific Ocean.

  • Violent Eruption at Merapi Volcano, Ash Ejection to 20,000 Feet, Indonesia

    Indonesia's Mount Merapi has erupted twice on Sunday, June 21, 2020, ejecting ash up to 6 000 m (20 000 feet) into the sky, according to the Center for Volcanology and Geological Hazard Mitigation (PVMBG). The first explosion occurred at 02:13 UTC (09:13 LT) and lasted for more than five minutes, while the second one took place minutes later at 02:27 UTC (09:13 LT), with a duration of about 2 minutes.

    As of 09:16 UTC (16:16 LT) on June 21, the Aviation Color Code is Yellow, which indicates that volcanic activity has decreased significantly but continues to be monitored closely for a possible increase.

    The direction of the wind to the west caused ash to fall in the regencies of Magelang and Kulonprogo, as said in a statement issued by the Yogyakarta Geological Disaster Technology Research and Development Center (BPPTKG).

    "Both eruptions were recorded on a seismogram with an amplitude of 75 mm," it wrote. The column height reached more than 6 000 m (20 000 feet) from the summit.

    The Magelang Regency Disaster Management Agency (BPBD) reports that light and heavy volcanic ash rain showered 39 villages in 8 sub-districts in the Magelang Regency: Srumbung (heavy), Dukun (light), Sawangan (light), Salam (light), Muntilan (light), Ngluwar (light), Mungkid (light), and Borobudur (light).

    Indonesia’s Badan Nasional Penanggulangan Bencana (BNPB) reports that thin ash is distributed in several areas around the slopes of Mount Merapi (Tlogo Lele, Boyolali Regency, Central Java). Whereas in other places, residents in the Turi, Pakem and Yogyakarta cities do not see volcanic ash.

    The farthest ashfall was reported in the Grimulyo District area, Kulon Progo, which is about 45 km (28 miles) from the volcano's peak.

    BPPTKG noted that prior to the explosive eruption, there has been an increase in seismicity since June 8. There were 80 volcanic-tectonic earthquakes between that day up to June 20.

    The agency warned people to avoid the area within a radius of 3 km (1.9 miles) from Merapi's peak.

    Mount Merapi is one of Indonesia's most active volcanoes. In 2010, an eruption killed more than 300 and forced almost 400 000 to evacuate.

    Geological summary

    Merapi, one of Indonesia's most active volcanoes, lies in one of the world's most densely populated areas and dominates the landscape immediately north of the major city of Yogyakarta. It is the youngest and southernmost of a volcanic chain extending NNW to the Ungaran volcano.

    Growth of Old Merapi during the Pleistocene ended with major edifice collapse perhaps about 2 000 years ago, leaving a large arcuate scarp cutting the eroded older Batulawang volcano. 

    Subsequently, the growth of the steep-sided Young Merapi edifice, its upper part unvegetated due to frequent eruptive activity, began SW of the earlier collapse scarp. Pyroclastic flows and lahars accompanying growth and collapse of the steep-sided active summit lava dome have devastated cultivated lands on the western-to-southern flanks and caused many fatalities during historical time.
