An Indonesian volcano which triggered the deadly 2018 tsunami has erupted again, shooting a huge column of ash into the sky.
Anak Krakatau, a volcanic island between Java and Sumatra, was continuously erupting until Saturday morning, according to scientists.
CCTV from Indonesia's Center for Volcanology and Geological Disaster Mitigation showed huge lava flares on Friday night.
This latest eruption is the longest since the explosive collapse of the island caused the 2018 tsunami, scientist said on Saturday.
A level two alert status remained in place - the second-highest on a scale of four. There were no casualties reported.
The 2018 eruption caused a tsunami along the coasts of Sumatra and Java, killing 430 people.
Scientists said that explosion was so violent the volcano was now only a quarter of its previous size, meaning any future tsunami would be far less severe.
Dr Kayla Lacovino, a volcanologist at Nasa, on Friday night tweeted: "Krakatoa volcano is erupting RIGHT NOW! This explosive eruption is producing strong lava fountaining and is the strongest eruption since the [2018 event]."
She added: "This is a big eruption for this volcano, but there is no reason to lose sleep."
Anak Krakatau, which means Child of Kratakau, is the offspring of the famous Krakatau volcano, whose monumental eruption in 1883 triggered a period of global cooling.
