Indonesia volcano Mount Merapi in new eruption

Indonesia's Mount Merapi volcano has erupted again, with greater force than last week's eruptions in which 36 people died.

The safety cordon around Mount Merapi has now been increased from ten to fifteen kilometres and the President has visited the area to check on the relief efforts.

An estimated 75,000 people have been evacuated from the area since Mount Merapi first erupted last Tuesday.

Indonesia is also dealing with the aftermath of another natural disaster, after a tsunami hit the Mentawai islands last week, claiming more than 400 lives and sending thousands into emergency shelters.
