Satellites tracking Mt Merapi volcanic ash clouds
15 November 2010
Since its latest series of deadly eruptions, Java’s Mt Merapi has been spewing volcanic ash clouds into the air. Satellite data are crucial for assessing the eruption’s danger to air traffic and public safety.
Mt Merapi began erupting on 26 October and has killed more than 200 people. Numerous international flights in and out of the Indonesia area have been cancelled due to ash clouds.
Flying through such clouds is a threat to safety because the damaging particles can lead to engine failure.
