Tsunami volcano lost two-thirds of its height

A section of Anak Krakatoa's crater collapsed after an eruption and slid into the ocean, generating the tsunami last Saturday night.

The eruption caused massive tsunami waves at least 2 metres high taking the islands of Sumatra and Java by surprise, killing over 400 people and leaving around 40,000 homeless. The eruption was one of the first global news events after telegraph lines had connected the different continents.

This support will allow the Indonesian Red Cross, which is working alongside the Indonesian Government, to deliver essential humanitarian assistance to an estimated 167,000 people affected by this latest tsunami over the next 30 months.

Given the volcano's remaining low volume, the agency said the possibility of another tsunami being triggered by an eruption is low.

About it reports Deutsche Welle with reference to the Indonesian National office for natural disasters.


Indonesia's disaster management agency (BNPB) has imposed a three-mile exclusion zone and raised the alert level from two to three because of the heightened volcanic activity - which amounts to nearly one eruption per minute.

"This morning we tried to take an aerial photo from the plane to confirm the satellite image but failed due to cloud cover", Prasetya said.

Saturday's disaster struck without warning, surprising people in a country that regularly suffers landslides, earthquakes and volcanic eruptions.

Authorities have warned Sunda Strait residents to stay a kilometer away from the coastline, citing the potential for another tsunami.

Indonesian authorities issued a warning for "extreme weather and high waves" on Wednesday, warning the weather is another factor that could cause parts of the weakened volcanic crater to collapse in a landslide. Some 7,202 were injured and almost 1,300 homes were destroyed after the waves crashed into the coastlines of western Java and southern Sumatra. It said 23 are missing and more than 40,000 displaced.
