A ministry official explained that rain of medium or high intensity could carry volcanic materials that are believed to be accumulating at the volcano's peak down to the villages.
Due to the severe impact of volcanic ash from Mount Lewotobi on Sikka, refugees at the two shelters in the district will be gradually shifted to East Flores.
The earthquake was centered at sea, some 95 kilometers northwest of Sinabang-Aceh, at a depth of 22 kilometers.
