Krakatau Volcano (Indonesia):Continuous Intense Explosions Heard 42 Km Away, Off Scale Seismicity

Our Indonesian volcano expedition leader Andi has sent us the below video of the current seismicity of Anak Krakatau: “Krakatau is going crazy …100 times explosion a day … very loud could be heard untill Carita 42 km away.

The explosive activity of the volcano continues and seems to be increasing with strombolian to vulcanian-style explosions from the summit crater.

Ash plumes can be seen on satellite imagery now, but so far have been low and do not affect air traffic significantly.

We will be visiting the island and camp 3 nights during our next Volcano Special tour from 10-15 August.

Hawaii Kilauea Volcano Update: School, Park Destroyed By Lava, Collapse Events Continue

The Kilauea volcano in Hawaii continues to cause disruptions in daily life for the people on the island. Near-daily collapse events that feel like earthquakes are rocking the island where some people have lost homes since the volcano started erupting in early May.

Lava is continuously flowing from Fissure 8 and a channel, or river, of lava has formed that leads from the fissure to the ocean. That ocean entry point filled an entire bay with lava. A map from the United States Geological Survey shows where the coastline was before it was covered with lava.

That map, which is up to date as of Thursday, also shows that while there were two entry points where the lava was entering the ocean earlier this week, there is now only one.

The channel of lava that formed from Fissure 8 was experiencing some blockages and consequent overflows earlier this week, which have since stopped. On Thursday afternoon, the caldera of the volcano, or the area above the magma pit that’s been feeding the fissures, experienced a collapse event. These events have been fairly common at Kilauea, but each one causes what feels like an earthquake on the island.

Thursday’s collapse event caused an increase in activity from Fissure 8, but the lava didn’t significantly overflow the edges of the channel due to the collapse, according to the USGS. Typically after each collapse, the seismic activity around the summit decreases for a few hours before ramping back up until the next collapse event. Hawaii Civil Defense recommends that residents “check their utility connections of electricity, water and gas after earthquakes.”

One of the most recent island locations to be overrun with lava was Ahalanui Beach Park and the Kua O Ka La Public Charter School along Highway 137, the Hawaii Tribune-Herald reported.

In addition to the danger hot flowing lava presents, there are also gases being released into the air from the lava and the summit of the volcano, as well as where the lava is meeting the ocean.

The ocean-entry point created a lava haze, or laze, plume that is made up of steam and hydrochloric acid and which can cause lung damage to anyone who gets too close. The reaction of the cold water meeting the hot lava can also produce explosive episodes that are potentially dangerous.

The volcano itself was releasing sulfur dioxide and volcanic ash and glass, which can cause irritation to the eyes, skin and lungs.

Scientists Finish Groundbreaking Volcano Mission

A mission off New Zealand’s coast has broken new-ground – literally – with scientists going where none have gone before.

Geologists on a trip to the Kermadec Arc – 400km northeast of White Island – have managed to drill into the heart of an underwater volcano, more than 1600m below the surface, and extract samples.

The Joides Resolution returned to Auckland this week and chief scientist Cornel De Ronde has been welcoming people aboard to share the expedition’s success.

It was very rare to be able to drill through any volcano, let alone one so deep in the ocean, he said.

“We were very lucky that this international consortium thought that this was a pretty good idea, all based on science,” Mr De Ronde said.

“It was five years in the making and $20 million in the costs.”

The scientists spent two months drilling into Brothers, a massive underwater volcano which is about three times the size of White island.

The oval shaped volcano is 13km-long and 8km-wide.

Mr De Ronde said scientists knew more about the dark side of the moon than they did about the ocean floor, but information from the Brothers would help answer some key questions.

“How are metals transported through volcanoes … what metals are there, how did they get there and where are they going?

Scientist Tobias Hofig said at one point they struck rock so hard and hot fluids so acidic that some of their drilling equipment was destroyed.

However, they still managed to recover more than 200m of volcanic core.

The trip was funded by a consortium of 23 countries that make up the International Ocean Discovery Programme, with the United States being the main funder.

Mr de Ronde said the expedition had been a career highlight.

“It was spectacularly successful. The technology used enabled us to do what we did.

“Once you get a bunch of people together with a common goal it’s amazing what you can achieve.”

Scientists will now spend the next year poring over the samples to help unearth more secrets around how and why submarine volcanoes work.

‘Lava Tornado’ Sends Hot Molten Stuff Flying As Kilauea Volcano Continues To Erupt

While fireworks filled skies across the nation at the start of July, Kilauea volcano on Hawaii’s Big Island might have put on the most spectacular show this week.

A vortex of rapidly swirling air flung red glowing bits of molten rock, creating what several publications have dubbed a “lava tornado.”

Scientists at the United States Geological Survey used a telephoto lens to capture video footage of the whirlwind above an river of lava flowing from an opening in the ground known as fissure No. 8.

The activity lasted for 10 minutes on July 2 and threw lava several meters away, the USGS reports.

Lava has destroyed more than 600 homes on the Big Island since the volcano began spraying molten rock out of a vent on a residential street on May 3.

At Kilauea’s summit, there continue to be explosions that shoot plumes of ash into the sky.

Ash expelled during explosions may cause poor visibility and slippery conditions for drivers.

Another ongoing hazard comes from lava meeting the ocean. Scientists warn against venturing too close to the action, saying it could expose people to dangers from flying debris.

Hawaii Kilauea Volcano Update: USGS Map, Summit Collapses Continue, Lava Flowing From Fissure 8

People on the Big Island of Hawaii have been dealing with the eruptions and collapse events from the Kilauea volcano for almost two months now. Activity at the summit of the volcano continues with collapse events, and lava is still flowing from the island’s Fissure 8.

Friday morning in Hawaii, there was a collapse explosion that sent a plume of volcanic material into the sky and drifting southwest of the summit according to the United States Geological Survey. But the levels of sulfur dioxide, the gas that Kilauea releases, were actually down from where they had been when the volcano first started erupting.

The next morning, there was another collapse event. That event occurred after about 15 hours of elevated seismic activity around the summit. It resulted in a steam plume that went about 500 feet in the air, similar to the previous explosion.

After the explosive events, the seismicity in the area dropped significantly by about two-thirds. Prior to the events, there were about 30 to 35 earthquakes an hour resulting from the volcanic activity, after the collapse events that dropped to 10 or less for a short period before the activity increased again, according to the USGS.

In addition to the collapse events that have resulted in the loss of a parking lot and a GPS station for measuring collapse, the lava that has already claimed hundreds of homes is still flowing.

Fissure 8 is still erupting lava and flowing into a channel. The channel does occasionally experience small and temporary overflows, according to the USGS. The spatter cone of the fissure was reaching about 155 feet tall as of Saturday morning. The lava that was coming from the fissure was flowing down to the ocean, where it had filled the entire Kapoho Bay and moved onto the Kapoho Beach Lots, said the USGS.

The lava was entering the ocean and causing a dangerous byproduct called laze, short for lava haze, that officials were warning people to avoid. The plume can damage the lungs and the skin as well as the eyes. The point where the lava enters the ocean can also experience small explosions, the USGS warned.

Around Fissure 8, volcanic glass including Pele’s hair was falling, more particles that residents were asked to avoid due to the irritation they can cause.

Bali Volcano Hurls Lava In New Eruption

The Mount Agung volcano on the Indonesian tourist island of Bali erupted on Monday evening, ejecting a 2000-metre-high column of thick ash and hurling lava down its slopes.

The Indonesian geological agency’s Agung monitoring post said explosions from the mountain began just after 9pm local time and lasted more than 7 minutes. “Flares of incandescent lava” reached 2 kilometres from the crater, it said, setting fire to forests at high elevation on the mountain.

It said the alert level for Agung has not been raised and the exclusion zone around the crater remains at 4km.

The National Disaster Mitigation Agency said ash was drifting west and the island’s airport, located in the south of Bali, was still operating normally. There have been no reports of injuries.

Last week, Bali’s international airport closed for half a day due to volcanic ash from Agung, disrupting travel for tens of thousands.

Monday’s eruption was “strombolian”, the geological agency said, which is the mildest type of explosive volcanic eruption. It warned people living near rivers to exercise caution, particularly in wet weather, because of the risk of fast- moving flows of muddy volcanic debris.

The volcano, about 70km north-east of Bali’s tourist hotspot of Kuta, last had a major eruption in 1963, killing about 1100 people.

It had a dramatic increase in activity last year, forcing the evacuation of tens of thousands of people, but had quietened by early this year. Authorities lowered its alert status from the highest level in February.

Indonesia, an archipelago of more than 250 million people, sits on the Pacific “Ring of Fire” and is prone to earthquakes and volcanic eruptions. Government seismologists monitor more than 120 active volcanoes.

Bali Volcano Eruption Halts Some Flights

Several flights were canceled or rescheduled on Thursday when Mount Agung volcano erupted on the Indonesian holiday island of Bali, sending a column of ash and smoke at least 2 km into the air, officials said.

Bali airport was operating normally, but some airlines said they had canceled flights to and from the island known for its beaches and temples.

“The eruption of Mount Agung today has impacted several of our flights to and from Bali,” budget carrier AirAsia said in a statement, adding at least 27 flights had been canceled or rescheduled.

Jetstar and Virgin Australia also canceled flights, according to media. Hundreds of passengers were expected to be affected. Airlines avoid flying through volcanic ash as it can damage aircraft engines, clog fuel and cooling systems and hamper visibility.
