The volume of the volcano also shrunk between 150 and 180 million cubic meters as a large amount of rocks and ash also slid into the sea. /VCG Photo

The tsunami destroyed nearly 1,300 homes and injured 7,202 people. More than 40,000 people have been evacuated in case a tsunami hits the island again. /VCG Photo
