Bali: Uitbarsting van de vulkaan Agung

quote:

Lava floods re-occur in Tukad Esah slopes of Mount Agung on 5/12/2017. People do not approach rain lava floods. Later approach and grab the sand if it is safe and Mount Agung is back to normal. One blessing of the eruption of Mount Agung.

The strength of lava flood floods can wash away large stones so that hit the bridge. The strength of rain lava flood is greater than that of conventional flood waters. Large stones can drift, let alone people who do near the river.

New lava dome groing in crater
At the surface, the explosive activity of the volcano has been declining during the past week and the ash and steam emissions have decreased considerably. Only a weak steam and gas plume has been observed since yesterday from the crater.

However, this apparent calm does not mean at all that the eruption is over. Rather that tts style is changing: it has entered a more effusive stage, with viscous lava accumulating in the summit crater as a new lava dome, which is what volcanologists have recently confirmed.

According to PVMBG, the Center for Volcanology and Mitigation of Geological Hazards, Agung's new lava dome has already grown to approx. 30 million cubic meters of volume, and it is estimated that this corresponds to about 50% of the available magma volume ready to erupt.

The pace of growth has been worryingly fast: within a few days, the total volume of the dome was claimed to have increased by 10 million cubic meters.

Based on such estimates, the eruption could fill the crater (about 900 m wide and 200 m deep and thus has a capacity of 60 million cu meters) within the next 5-10 days only. At that stage, the eruption will become extremely dangerous: when lava starts to spill over the crater, the viscous, blocky lava will likely generate hot avalanches (pyroclastic flows), that can travel for many kilometers at high speed and devastate everything in their path.

However, this scenario will only happen if the supply of magma is large enough and the eruption still continues, something difficult to know. On the other hand, it seems rather likely that the magma supply is far from being exhausted at the moment: tremor episodes related to magma flowing upwards inside the conduit continue to occur, and ground deformation measurements indicate continuing inflation of the edifice, both indications that more magma is going to be erupted.

PVMBG plans to monitor the crater visually by a drone, but has been facing technical difficulties.

Bali volcano update: Mount Agung erupts and sends huge plume of ash into sky over Bali
BALI’s highest volcano erupted again today and sent a huge plume of ash 2,500m into the sky as a reminder that the danger has not yet passed.

Mount Agung was pictured sending up a billowing ash cloud in Bali earlier after a period of relative calm and only intermittent eruptions.

The Bali volcano erupted at 5.54pm local time on the holiday island, according to Indonesia’s National Agency for Disaster Management (BNPB).

BNPB spokesman Sutopo Purwo Nugroho said ash rained down on villages of Kubu and Tulamben near popular dive sites with impressive reef.

But he confirmed that the airport is operating normally and the ash cloud had not led to the delay or cancellation of flights.

Frances Boreham, a PhD student at University of Bristol studying lava-water interactions, retweeted a photograph of ash cloud shared by Sutopo.

She tweeted: “Ash plume from an eruption at Mount #Agung in #Bali earlier today.

“A reminder to respect the exclusion zone around the volcano - it's still very active and dangerous!”

Volcano erupts after alert level lowered in popular honeymoon island Bali

A volcano on the Indonesian resort island of Bali erupted on Tuesday, days after authorities lowered its alert level one notch, an official said.

Mount Agung spewed gray ash 1,500 meters into the atmosphere, said Sutopo Nugroho, spokesman for the National Disaster Management Agency.

There were no casualties, he said.

On Saturday, authorities lowered the volcano's warning level one notch from the highest level after a steady decrease in activity.

The exclusion zone was reduced from 6 kilometers to 4 kilometers, allowing thousands of people who had stayed in temporary shelters to return home.

But about 15,000 evacuees remained in the shelters, too afraid to return to their homes near the volcano, Sutopo said.

Mount Agung erupts on Feb 13, 2018

New eruption from Agung

Several eruptions were registered at Indonesia's Mount Agung volcano in Bali on June 27 and 28, 2018. The eruptions produced a dense ash plume that rose up to 5 km above sea level and forced AirAsia to cancel numerous flights on June 28. Officials in Ngurah Rai International Airport are still assessing whether to halt operations again.

Agung erupted on Thursday, June 28, 2018, producing a dense white and black volcanic ash plume that rose up to 1.5 to 2 km (5 000 - 6 500 feet) above crater summit. This is up to 5 km (16 404 feet) above sea level.

Ashfall was reported in nearby communities.

At least 27 AirAsia flights scheduled to arrive to and to depart from I Gusti Ngurah Rai International Airport (DPS), Denpasar have been canceled or postponed and the company urged all guests to update their contact details at airasia.com to ensure that they are notified of any updates to their flights.

Ngurah Rai officials are assessing whether to temporarily halt operations following Mount Agung’s latest eruption, their spokesperson said.

While flights on other airlines are currently all on schedule, anyone flying to our out of Bali is urged to contact their airline.

The Alert Level remains at 3 (on a scale of 1 - 4) and the 4-km-radius (2.5 miles) exclusion zone remains in effect.

Authorities are urging residents living close to the volcano as well as tourists to respect the exclusion zone.

Vliegveld Bali gesloten vanwege vulkanische as na uitbarsting

Het vliegveld van Bali blijft vrijdag tot 13.00 uur Nederlandse tijd gesloten vanwege een vulkaanuitbarsting in het noordoosten van het eiland. Bij de uitbarsting is veel as vrijgekomen.
De vulkaan Agung is recentelijk na bijna een jaar inactiviteit weer ontwaakt. De rampenbestrijdingsdienst van Indonesië heeft aswolken van 2,5 kilometer en vlammen waargenomen die vanuit de Agung omhoog kwamen.

Veel as is neergekomen op de start- en landingsbanen van het Indonesische eiland. Daarom hebben de autoriteiten besloten het vliegveld tijdelijk te sluiten.

De sluiting van luchthaven Ngurah Rai bij de stad Denpasar heeft tot nu toe gevolgen voor ruim zestienduizend passagiers. Zeker 38 internationale en 191 lokale vluchten zijn geannuleerd. Ook de vliegvelden Banyuwangi en Jember op Oost-Java zijn tijdelijk dicht.

Luchtvaartmaatschappijen mijden het vliegen door vulkaanas, omdat dit schade kan veroorzaken aan vliegtuigmotoren, brandstof- en koelsystemen kan verstoppen en het zicht kan belemmeren.

Evacuatie
Vrijdag hebben ruim driehonderd bewoners binnen een gevarenzone van 4 kilometer het gebied vrijwillig verlaten. De autoriteiten houden de omstandigheden nauwlettend in de gaten, maar hebben het dreigingsniveau voor de vulkaan nog niet verhoogd.

Afgelopen december is de luchthaven van Bali ook al kort gesloten geweest, nadat de vulkaan in het noordwesten van het eiland weer actief was geworden. Daarnaast werden duizenden mensen uit voorzorg geëvacueerd.

Agung ejects ash to 5.2 km high
A moderately strong eruption took place at Mount Agung, Bali, Indonesia at 01:05 UTC (09:05 local time) on July 15, 2018. Ash column rose up to 5.2 km (17 000 feet) above sea level, according to Darwin VAAC. The eruption lasted 1 minute and 45 seconds.

"The ash cloud is observed as a thick intense cloud that tends to face the southeast region and west," said Sutopo Purwo Nugroho, spokesperson for the National Disaster Mitigation Agency (BNPB).

The event was preceded by a smaller but longer (2 minutes and 20 seconds) eruption at 20:52 UTC on July 14.

Ashfall was reported in nearby villages and communities.

ccording to Sutopo, Agung's status remains at level 3 ‘siaga.’

BNPB recommends people not to conduct any activities in the region considered to be within the danger zone, which includes hiking. The danger zone is 4 km (2.5 miles) around the crater.

While flights in and from Bali can sometimes be affected, today's eruption had no impact on the tourism industry and airports are secure and operating normally. This volcano is far away from tourist destinations.

Seismic activity is characterized by low frequency earthquakes.

Indonesian Mount Agung erupts again, sparking panic among locals, Bali

Indonesian Mount Agung erupted again at 17:31 UTC on April 3, 2019, ejecting volcanic ash up to 6 km (20 000 feet) above sea level. The Aviation Color Code remains Orange and Alert Level at 3 of 4.

Seismograph recorded and eruption amplitude of 25 mm and a duration of 3 minutes and 58 seconds, Mount Agung observatory reported, adding that thundering sound could be heard at the observatory, located about 2 km (1.2 miles) from the crater.

The eruption caused panic among residents praying at Besakih Temple, located 9 km (5.6 miles) from the volcano. According to the Jakarta Post, many reportedly screamed in panic when they heard rumbling sounds during their visit to the temple for Panca Wali Krama, a major Balinese Hindu ceremony.

Authorities are warning everyone to steer clear of the danger zone which is still 4 km (2.5 miles) from the crater.

People living along the rivers at the foot of the volcano have been warned to watch for a possible lava flow that could come on rainy days.

Bali is still safe and the airport is operating normally, authorities said.
The last eruption of this volcano took place on March 28, 2019
