The Indonesian Anak Krakatau volcano erupted expelling ash and plumes of smoke that travelled more than 500 metres high, local authorities report on Saturday.
The Centre for Volcanology and Geological Disaster Mitigation (PVMBG) said the volcano, one of the country’s most active, erupted twice on Friday night for a total of 40 minutes, reports Efe news.
“PVMBG monitoring shows that the eruption continued until Saturday morning at 5:44 WIB [Western Indonesian Time],” Agus Wibowo, head of the National Disaster Mitigation Agency (BNPB) said in a statement on Saturday.
Authorities said they were closely monitoring the volcano which is located on an uninhabited island in the Sunda Strait.
On December 22 2018, a strong eruption caused a landslide that triggered a tsunami killing hundreds of people who were spending the Christmas holidays on the coasts of Java and Sumatra.
At least 439 people died and more than 7,200 were injured, according to official figures.
