This is an update to the double disaster in Indonesia.
Late Monday, a 7.7 magnitude earthquake in Sumatra caused a killer tsunami.
At least 113 people were killed and more than 500 people were missing.
The tsunami hit remote islands that takes about 12 hours boat trip from Padang.
Those islands are popular surfing spots.
10 villages were swept away by waves as high as 3 meters (10 feet).
On Tuesday, less than 24 hours after the tsunami, Mount Merapi in central Java erupted.
At least 25 people were killed in this disaster.
Government volcanologist Surono told AFP that they heard 3 explosions around 6 pm (1100 GMT) spewing volcanic material as high as 1.5 kilometres (one mile) and sending heat clouds down the slopes.
Thousands of people were in makeshift emergency shelters late Tuesday.
The volcano is on the highest alert level.
Mount Merapi is Indonesian most active volcano.
Scientists have warned that pressure building beneath Merapi’s lava dome could trigger its most powerful explosion in years.
If that really happens, it will cause a great disaster.
Indonesia is in the Pacific ‘Ring of Fire’.
