New eruption fase started at Krakatau
Since February 17, 2017, a strong thermal signal is visible on satellite data from what seems to be the summit of Anak Krakatau (Child of Krakatau), the site of frequent eruptions since 1927. The last eruption of this volcano occurred on March 31, 2014 (VEI 1).

What causes the thermal signal exactly is unknown. While non-volcanic causes (e.g. forest fires) cannot be ruled out, it is more likely that a new mass of lava has arrived at the crater, probably in the form of a new dome, Volcano Discovery explains.

"In that case, Krakatau might be entering a new eruptive phase, something which would not be a surprise, statistically. So far, there is no confirmation of significant ash emissions observed, which could mean that the activity, if there is, is only effusive for now."

The last significant eruptive phase of this volcano began on July 31, 2011 and ended on September 9, 2012. It had Volcanic Explosivity Index of 2 (of 8).

The eruption at has been confirmed. VD's reader Aaron Brighton spent last night at Anak Krakatau and saw intense strombolian-vulcanian type activity from the summit.

New Small eruption at Krakatau volcano
A small eruption took place at Krakatau volcano, located between Java and Sumatra, on June 19, 2018. The last known eruption of this volcano took place on February 19, 2017.

The eruption produced ash that rose a few hundred meters before it dissipated, Volcano Discovery reports. "Whether this is a sign of a new, more robust eruptive phase at the volcano is too early to say, but clearly shows that the volcano is restless and could be ready for a new eruption in the near to medium term future (weeks, months from now)."

Thermal radiation has increased since March 2018 and is at low to moderate levels, also suggesting that magma is near the surface.

A strong thermal signal was observed at the volcano on February 17, 2017. This activity was followed by intense strombolian-vulcanian type activity at the summit on February 19.

Its previous eruption occurred on March 31, 2014 (VEI 1).

Eruptions intensify at Anak Krakatau
Explosive activity at Anak Krakatau in Indonesia continues and its seismicity is reportedly going off the scale today, July 12, 2018.

"Krakatau is going crazy ... 100 times explosion a day. Very loud and could be heard until Carita, 42 km (26 miles) away," Volcano Discovery's Indonesian volcano expedition leader said July 12.

Just a few hours ago, photographer and volcano-enthusiast ystein L. Andersen, said activity at the volcano is quite unique now. "It seems like you can now see a bright glow from the eruption from the coast of Java, 50 km (31 miles) away."

PVMBG reported there were four ash-producing events at Anak Krakatau on July 4 and 5, each lasting between 30 and 41 seconds. While inclement weather conditions prevented an estimation of the ash-plume height from the event at 05:22 local time on July 4, ash plumes from events at 14:09, 14:25, and 16:51 on July 5 rose 300 - 500 m above the crater rim and drifted N and NW.

‘Child of Krakatoa’ volcano flings lava bombs hundreds of feet during mesmerizing eruption

'Lava bombs' rain down after volcano erupts in Indonesia
James Reynolds of Earth Uncut TV witnessed Indonesia's Anak Krakatau volcano erupt on Aug. 12.
The Anak Krakatau volcano in Indonesia is shooting boulders out of its crater like fireworks. The “lava bombs” (yep, that’s a real thing) hurled into the sky on Saturday were as big as trucks, according to James Reynolds, the natural disaster chaser who shot the video you’re watching above.

Anak is only a century old — not even a blip on Earth’s geological timeline — but it’s already become one of the most-watched volcanoes in the world. That probably has to do with its lineage; Anak Krakatau is, geophysically speaking, Krakatoa’s volcanic child.

Krakatoa lives in infamy for its 1883 eruption. Between the pyroclastic flow, earthquakes, ash fall and tsunamis, the volcano killed tens of thousands of people that year. The sound of the eruption was heard in Australia and as far away as Rodrigues Island, which is closer to Madagascar than it is Indonesia.

The eruption nearly destroyed the volcano entirely. What spawned from the ash and debris was a new volcano, given the name Anak Krakatau, or “child of Krakatoa.” It literally rose up out of the ocean in 1927 and has been erupting continuously in one form or another since then.

Reynolds said explosions like the one in the video were happening approximately every half hour while he was there. The video was captured with a drone.

Krakatau volcano (Indonesia): eruption continues with no signs of weakening

The eruption of the volcano continues with no signs of weakening. Rather a slight increase in the number of reported explosions and the intensity of the heat signal can be noted on satellite data and the reports from the observatory on the coast who analyze the seismic data.
Whether the lava flow observed by Galih and his group 2 weeks ago is still active is currently unknown, but we will soon visit the volcano and report our eye-witness account afterwards.

VAAC Darwin reports near continuous ash emissions to 7-10,000 ft altitude drifting in various directions, visible on satellite data.
