In Indonesia, at least 108 people were killed and more than 500 were missing after a powerful earthquake on Monday triggered tsunami in Mentawai islands. Local media said that the search and rescue team is focusing on searching the missing people. However, high tides have hindered the rescue work, preventing the rescuers from reaching the stricken area. President Susilo Bambang Yudhoyono has declared an emergency response. Small tsunamis occurred five minutes after the 7.2 magnitude quake struck at 9:42 p.m. local time yesterday. The epicenter of the quake was located at 78 kilometres southwest Pagai Selatan Mentawai and at a depth of 10 kilometres under sea bed.Indonesia's most volatile volcano is also erupting, spewing plumes of hot ash and hurling rocks into the air. Officials said, the valcano – Merapi, in central Java, began erupting just before dusk today. Scientists warn the pressure building up beneath its lava dome could lead to one of the most powerful blasts in years. Thousands of residents living on the volcano's slopes have been evacuated. Television footage showed thousands of people fleeing the area, some covered in white ash.
