ANAK KRAKATAU

ANAK KRAKATAU


Your Guide to Vacation AMAZING INDONESIA ( holiday travel guide )

Krakatau, is a volcanic island made of lava in the Sunda Strait between the islands of Java and Sumatra in Indonesia. The name is used for the island group, the main island (also called Rakata), and the volcano as a whole. 



The island exploded in 1883, killing approximately 40,000 people, although some estimates put the death toll much higher. A new island volcano, named Anak Krakatau or Child of Krakatoa rose above the waterline in 1927. Anak Krakatau has grown at an average rate of five inches (13 cm) per week since the 1950s. This equates to an average growth of 6.8 meters per year. The island is still active, with its most recent eruptive episode having begun in 1994. Quiet periods of a few days have alternated with almost continuous Strombolian eruptions since then, with occasional much larger explosions. 


2014



16th September:

Status remain the same as earlier this year. A constant but moderate degassing from Anak-Krakatau can be observed at alle times. Seimsic data indicate low activity at the volcano, with only minor tremor and volcanic earthquakes present. No eruptions confirmed since October 2013.




23th April: 
According to a trusted source that visited Krakatau in the third week of April, new volcanic material was observed on the northern flanks of the volcano, indicating that the volcano (may) have erupted in early 2014. However during my source visit to the volcano, it did not erupt, but showed a more prominent degassing plume than was present during the second half of 2013.


2013

Seismicity increased in the first week of October, and reaching the highest levels of 2013 in November 2013. A high level of volcanic-tremor was recorded on the 3th and 4th October, followed by an increase in volcanic-a earthquakes in November.  The presence of increased occurence of volcanic tremor and shallow earthquakes may be a precursor to new erutptive activity at Krakatau. A crater glow has also been present troughout most of 2013, but the most intense glow was observed in November.


Recent eruptions:



My remote camera stationed at Krakatau captured ash-venting on the 31th October 2013, please see the November report for more details and a photo of the event.



Visited the volcano on the 4th to 5th October and 9th to 11th November. Please read these reports for more detailed info. on the current activity.
