Volcanoes Ignite Monitoring Efforts

摘要

The eruptions of Llaima in central Chile, which began on 3 April, and of Mount Redoubt in Alaska, which has been rumbling on since 22 March, have provided new impetus for volcano monitoring systems. In the United States, politicians have been galvanized by the eruption of Mount Redoubt (pictured), about 180 kilometres southwest of Anchorage. On 2 April Senator Lisa Murkowski (Republican, Alaska) introduced legislation to provide the US Geological Survey (USGS) with US$15 million a year for an expanded nationwide network of monitoring instruments.
