Krakatau volcano (Sunda Strait, Indonesia): strong thermal signal could suggest new eruptive activity
Sunday Feb 19, 2017 08:51 AM | BY: T
Heat signal from Krakatau volcano (MIROVA)As our colleague Marc Szeglat from Vulkane.net noticed, a strong thermal signal from what seems to be the summit of Anak Krakatau has become visible on satellite data during the past days.
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. In that case, Krakatau might be entering a new eruptive phase (the last significant eruption having being in sep 2012), something which would not be a surprise, statistically.
So far, there is no confirmation, e.g. there have been no significant ash emissions observed, which could mean that the activity (if there is) is only effusive for now. We wait for further information about possible activity and will update as needed.
Note for tours to Krakatau volcano:
As soon as new activity is confirmed and strong enough to merit it, we plan to organize an eruption special tour. if you're potentially interested in joining us on such a coming Krakatau Special, please contact us (best via email or through the inquiry form of the Krakatau Special).

The group of our current trekking tour on Java climbed the summit of Anak Krakatau on 24 June. Climbing there was very difficult, because of many hot fumarolic spots and strong degassing. The summit of Anak Krakatau is now higher than before the Sep 2012 eruption. One active vent was remaining in the west part. [more]
