Volcanic Eruptions

  • Exclusive drone video captured by ABS-CBN News cameraman Val Cuenca

    The aerial footage also shows houses in Sitio San Isidro, Talisay, Batangas covered in volcanic ash.

    Meanwhile cracks are eating up the groundaround the Taal volcano, while volcanic earthquakes seem to come to a rest. Hopefully this part of the Philippines won’t be hit by a stronger and even more catastrophic eruption. Prayers for everybody… Also for Australia.

    Strombolian-type explosions continued at Fuego volcano, Guatemala into Tuesday, February 4, 2020. The eruptions ranged around five to 10 per hour, producing a gray ash plume that reached roughly 4 500 to 4 700 m (up to 15 000 feet) above sea level and drifted west and southwest.

    According to the country's National Institute for Seismology, Vulcanology, Meteorology, and Hydrology (INSIVUMEH), the volcano emitted incandescence material to a height of approximately 100 to 300 m (328 to 984 feet) above the crater.

    In addition, lava flows on the Seca Canyon continue to be active.

    Several areas downwind reported ashfall, including Santa Sofia which was 12 km (7.4 miles) southwest, Morelia 9 km (5.6 miles) southwest, Panimache I and II 8 km (4.9 miles) southwest, Finca Palo Verde and San Pedro Yepocapa 8 km (4.9 miles) northwest, Sangre de Cristo 8 km (4.9 miles) west-southwest, and El Provenir 8 km (4.9 miles) east-northeast.

  • Kuchinoerabujima volcano in Kagoshima Prefecture, Japan erupted early Monday, February 3, 2020, ejecting volcanic ash up to 7 000 m (23 000 feet) above sea level.

    According to the Japan Meteorological Agency (JMA), pyroclastic flows -- the first since January 29, 2019 -- traveled around 900 m (2 953 feet) southwest of the crater.

    Authorities said the eruption threw volcanic material some 600 m (2 000 feet) around the crater, but no injuries have been reported. Damage to properties is yet to be confirmed

    Kuchinoerabujima volcano in Kagoshima Prefecture, Japan erupted early Monday, February 3, 2020, ejecting volcanic ash up to 7 000 m (23 000 feet) above sea level.

    According to the Japan Meteorological Agency (JMA), pyroclastic flows -- the first since January 29, 2019 -- traveled around 900 m (2 953 feet) southwest of the crater.

    Authorities said the eruption threw volcanic material some 600 m (2 000 feet) around the crater, but no injuries have been reported. Damage to properties is yet to be confirmed.

    The Alert Level remains at 3 (on a scale of 5) since 15:15 UTC on October 27, 2019 (00:15 JST, October 28), after a large earthquake hit the island. 

    ​"There is a possibility that an eruption will occur of a magnitude similar to the one in January when pyroclastic flows reached a point 1.9 km (1.2 miles) from the crater," JMA said at the time.

    Kuchinoerabu Island, which is around 130 km (81 miles) south-southwest of Kagoshima city, covers an area of 36 km2 (14 mi2) and is home to 100 people as of December 2019.

    Explosive eruptions in May 2015 forced all islanders to evacuate to Yakushima island-- 12 km (7 miles) east. Eruptions in 1980 and 1933, destroyed a village, killed up to eight people, and affected 26 others.

     

     

     

  • A volcano on the Indian Ocean island of Reunion is spewing red hot lava into the surrounding countryside and sending plumes of smoke into the air.

    Dramatic footage filmed from a helicopter has captured the molten rock pouring out of the Piton de la Fournaise volcano and stretching across the striking landscape as smoke fills the air.

    The squat volcano is one of the most active in the world, periodically erupting for long stretches of time. The current eruption began all the way back in October 2019 and is still going strong.

    Several cracks have opened on the eastern flank of the volcano between the summit area and 2,000 meters above sea level, the island's volcanological observatory said on Monday.

    Reunion is part of France, though it lies 175 kilometers (109 miles) off the coast of Madagascar.

  • A strong explosion took place at Mexico's Popocatepetl volcano at 12:31 UTC (06:31 LT) on January 9, 2020. At least two volcanic ash clouds were produced today, with initial rising up to 11.3 km (37 000 feet) above sea level, and second to 9.1 km (30 000 feet) a.s.l. The Alert Level remained at Yellow, Phase Two (the middle level on a three-color scale).

    The explosion threw incandescent material at a distance of 1 km (0.62 miles) from the edge of the crater.

    In 24 hours to 17:00 UTC today, monitoring systems recorded 268 exhalations composed of water vapor, volcanic gases, and low ash content. Additionally, 90 minutes of tremor were recorded and 1 volcano-tectonic earthquake at 16:10 UTC on January 8 with a magnitude of 1.4.

    Although CENAPRED initially reported ash cloud to 3 km (9 800 feet), according to data provided by the Washington VAAC, it rose to 11.3 km (37 000 feet) a.s.l. by 13:46 UTC, drifting SE and stretching 140 km (86 miles) from the summit.

    The initial volcanic ash cloud dissipated by 18:41 UTC and was no longer visible in satellite imagery. Second volcanic ash continued moving NNE at 18 km/h (11 mph) at a height of 8.2 km (27 000 feet) a.s.l., the Washington VAAC reported.

    Light ashfall was reported in the State of Mexico, Ozumba, Puebla, San Nicolás de los Ranchos, Chiautzingo, San Matías Tlalpaneca, and Teotlalzingo.

    CENAPRED urges residents and tourists not to approach the volcano, especially the crater, due to the danger of falling ballistic fragments and in case of heavy rains to move away from ravines due to the danger of mud and debris flows. Ignore rumors and be attentive to the information issued by the National Civil Protection Coordination through its official channels.

  • February 13, 2020, the Merapi volcano in Indonesia and the Nevado del Ruiz volcano in Colombia erupted strongly.

    The activity along the Ring of Fire isn’t decreasing at all.

    Within the last 24 hours, it experienced a M7.0 earthquakein the Kuril Islands and at least two volcanoes in Indonesia and Colombia inundated the sky with plumes of ash and gas.

    Merapi eruption – Indonesia

    The most active volcano in Indonesia spewed ash and gases around 6,500 feet in the air at 5:16 a.m. local time.

    The strong eruption lasted 150 seconds and ejected volcanic rocks across a 0.62-mile radius. Ashfall was reported in villages 6.2 miles south of the volcano.

    Officials warn tourists and locals to stay outside a nearly two-mile radius from the peak on fire.

    The volcanic activity of Merapi has been increasing since december 2019. Therefore violent eruptions similar to that of yesterday will happen in the future.

    Eruption Nevado del Ruiz – Colombia

    Plumes of ash and gas drifting 1,000 meters above the Nevado del Ruiz volcano were reported by the Geological Survey of Manizales / Colombia on February 13, 2020 at 10:25 am and 11:00 am.

  • Taal volcano in the Philippines started erupting at 06:04 UTC on January 12, 2020, for the first time since 1977. The volcanic ash cloud is reaching up to 16.7 km (55 000 feet) above sea level, according to data provided by the Tokyo VAAC.

    • PHIVOLCS said it strongly recommends Taal Volcano Island and high-risk barangays of Agoncillo and Laurel, Batangas be evacuated due to the possible hazards of pyroclastic density currents and volcanic tsunami.
    • Tall has produced some of the Philippines' most powerful eruptions. Powerful pyroclastic flows and surges from historical eruptions have caused many fatalities. Its last eruption took place in 1977 (VEI2).

    Taal volcano seismic network has manifested moderate to high level of seismic activity since March 28, 2019. Some of these earthquakes were felt with intensity ranging from Intensity I (Scarcely Perceptible) to Intensity III (Weak Shaking) in the barangays of Calauit, Balete, Sitio Tibag, Pira-Piraso, and Buco, Talisay, Alas-as and Pulangbato, San Nicolas, Batangas. Often, these felt earthquakes are accompanied by rumbling sounds.

    Three felt earthquake were recorded over the past 12 hours - at 23:35 UTC on January 11, 02:43 and 06:00 UTC on January 12.

    A seismic swarm has started at around 03:00 UTC (11:00 LT).

    PHIVOLCS raised the Alert Level at 08:00 UTC to 3 - this means that there is a magmatic intrusion that is likely driving the current activity.

    The Institute said it strongly recommends Taal Volcano Island and high-risk barangays of Agoncillo and Laurel, Batangas be evacuated due to the possible hazards of pyroclastic density currents and volcanic tsunami.

    The public is reminded that the entire Volcano Island is a Permanent Danger Zone (PDZ), and entry into the island as well as high-risk barangays of Agoncillo and Laurel is prohibited.

    In addition, communities around the Taal Lake shore are advised to take precautionary measures and be vigilant of possible lakewater disturbances related to the ongoing unrest.

    Update:

    PHIVOLCS raised the Alert Level from 3 (magmatic unrest) to 4 (hazardous eruption imminent) at 11:30 UTC. This means that hazardous explosive eruption is possible within hours to days.

    DOST-PHIVOLCS strongly reiterates total evacuation of Taal Volcano Island and additional evacuation of areas at high risk to pyroclastic density currents and volcanic tsunami within a 14 km (8.7 miles) radius from Taal Main Crater.

    Areas in the general north of Taal Volcano are advised to guard against the effects of heavy and prolonged ashfall. Civil aviation authorities must advise aircraft to avoid the airspace around Taal Volcano as airborne ash and ballistic fragments from the eruption column pose hazards to aircraft.

    As of 09:30 UTC (17:30 LT), eruptive activity at Taal Volcano Main Crater intensified as continuous eruption generated a tall 10-15 km (33 000 - 49 000 feet) steam-laden tephra column with frequent volcanic lightning that rained wet ashfall on the general north as far as Quezon City, PHIVOLCS reported.

    Volcanic tremor was recorded continuously since 03:00 UTC and two volcanic earthquakes of magnitudes M2.5 and M3.9 were felt at Intensity III in Tagaytay City and Alitagtag, Batangas were recorded at 10:15 and 10:22 UTC (18:15 and 18:22 PST), respectively.

    Ashfall was reported in Metro Manilla (100 km / 62 miles) N of Taal.

    All flights at Ninoy Aquino International Airport are on a delay, and passengers advised to coordinate with airlines for updates.

    Evacuations are underway in the municipalities of San Nicolas, Balete and Talisay.

    Classes within the provinces of Cavite, Batangas, Rizal and Laguna will be canceled on Monday, Januar 13. due to heavy ashfall.

    Manila City Mayor Isko Moreno has also ordered the suspension of classes in all levels of public and private schools on Monday.

    ​"Magma is intruding from below. If eventually this will continue to move up, then there can be a magmatic eruption which is more dangerous," PHIVOLCS head Renato Soldium said.

  • Multiple new fissures (cracks) were observed around Taal volcano on January 14, 2020, two days after intense unrest began. Fissures, accompanied by intense seismicity activity, are an indication of an imminent explosive eruption, PHIVOLCS warns. The agency strongly reiterated total evacuation of Taal Volcano Island and areas at high risk to pyroclastic density currents and volcanic tsunami within a 14 km (8.6 miles) radius from the volcano. Areas around the volcano are advised to guard against the effects of heavy and prolonged ashfall. New eruption could force more than 200 000 additional people from their homes.

    Taal volcano entered a period of intense unrestbeginning with phreatic / steam-driven eruption at several points inside the Main Crater at 06:04 UTC on January 12, 2020. The activity progressed into a magmatic eruption from 08:49 to 20:28 UTC, characterized by weak lava fountaining accompanied by thunder and flashes of lightning. According to the Tokyo VAAC, volcanic ash cloud reached an altitude of 16.7 km (55 000 feet) above sea level. Sulfur dioxide (SO2) emission was measured at an average of 5 299 tonnes/day on January 13, 2020.

    In 24 hours to 00:00 UTC on January 14, the activity was characterized by the continuous eruption at the Main Crater due to magmatic and hydrovolcanic activity. This ongoing eruption generated 500-meter (1 640 feet) tall lava fountains topped by dark gray steam-laden plumes reaching approximately 2 km (1.2 miles) that dispersed ash to the southwest and west of the Main Crater. Flashes of volcanic lightning were observed at the base of the degassing plumes.

    New vents opened up on the northern flank, with 500 m (1 640 feet) tall lava fountains, and within the main crater where steam plumes, have emanated.

    Heavy ashfall from the ongoing continuous activity has fallen on the municipalities of Lemery, Talisay, Taal, and Cuenca, Batangas. 

    By 02:00 UTC on January 14, PHIVOLCS registered a total of 336 volcanic earthquakes, of which 133 were felt -- M1.2 to 4.1.

    At 05:00 UTC, lava fountains generated 800 m (2 620 feet) tall dark gray steam-laden plumes that drifted to the general southwest.

    New fissures or cracks were observed in Sinisian, Mahabang Dahilig, Dayapan, Palanas, Sangalang, Poblacion, Lemery; Pansipit, Agoncillo; Poblacion 1, Poblacion 2, Poblacion 3, Poblacion 5, Talisay and Poblacion, San Nicolas. A fissure was also documented across the road connecting Agoncillo to Laurel, Batangas.

    PHIVOLCS said that fissuring on the caldera region means that the top of the volcano has been depressurized and the high volume of magma continues to rise, indicating an imminent explosive eruption. Another indication of an impending explosive eruption is an intense seismic activity.

    The agency added that similar fissures have appeared before the explosive eruption of 1911 (January 27 - February 8; VEI 3).

    A total of 40 752 people were affected; of which 38 203 are taking temporary shelter in 198 evacuation centers, NDRRMC reported at 10:00 UTC today. 

    Alert Level 4 still remains in effect - this means that hazardous explosive eruption is possible within hours to days.

    PHIVOLCS strongly reiterates total evacuation of Taal Volcano Island and areas at high risk to pyroclastic density currents and volcanic tsunami within a 14 km (8.6 miles) radius from Taal Main Crater. Areas around Taal Volcano are advised to guard against the effects of heavy and prolonged ashfall.

  • Phreatomagmatic activity at the Indonesian Anak Krakatau volcano has increased over the past couple of days. This is the site of a major eruption and resulting tsunami on December 22, 2018 (see image below), during which at least 426 people lost their lives and 30 000 were injured, 

    Several eruptive episodes took place since 10:29 UTC on October 28, resulting in three Orange VONAs by 09:31 UTC today (VONA, Volcano Observatory Notification for Aviation).

    The Darwin VAAC is reporting continuous volcanic ash up to 3 km (10 000 feet) above sea level on December 30.

    The height of the plume is variable depending on eruption strength. 3 km (10 000 feet) is highest observed to far SW, based on Himawari-8 imagery acquired at 09:10 UTC today, Jakarta sounding at 00:00 UTC today and model guidance.

     

    Much of the island of Anak Krakatau was destroyed in a series of events that included a deadly tsunami from a flank collapse, a Vulcanian explosion, and several days of Surtseyan phreatomagmatic activity1

    Due to the location of the volcano in the middle of the Sunda Strait, surrounded by coastal communities, damage from the tsunami was once again significant. Over 400 fatalities and 30 000 injuries were reported along with damage to thousands of homes, businesses, and boats.

    After a small explosion on January 8, 2019, the volcano remained quiet until February 14 when a new seismic event was recorded. Intermittent explosions increased in frequency and continued through July 2019; images of Surtseyan explosions with ejecta and steam rising a few hundred meters were occasionally captured.
