Activity at Merapi volcano declined through November 2010 and a fieldtrip by our team in early December 2010 found that ash had been rapidly removed from the environment by heavy rainfall.

A new study led by IVHHN Director Claire Horwell has concluded that the ash from the Icelandic volcano Eyjafjallajökull earlier this year does not have the potential to cause long-term respiratory health problems for Icelanders.

Cities on Volcanoes

Cities on Volcanoes 6 will take place at Puerto de la Cruz, Tenerife (Canary Islands, Spain) in May-June 2010. There will be a session dedicated to volcanic health hazards and IVHHN will be holding a workshop at the conference too.
