Indonesia's volcano in Central Java erupted again today, spewing hot ash by up to 1, 500 meters high. Mount Merapi, which means Mountain of Fire, has been spewing ash and heat clouds since late October, killing people with torrents of boiling hot gas and rock and forcing over 3 lakh people to flee to makeshift camps. The number of fatality climbed to 191 people with 598 people suffering from serious injuries.A government volcanologist said the pace of the eruption had slowed, but the ash spread to all direction by up to over 50 kilometers away. The ash caused major disruptions to flights in and out of Indonesia at the weekend and forced US President Barack Obama to cut short his trip to the sprawling archipelago today.
