U.S. to upgrade volcano, earthquake monitoring


U.S. government will spend $15.2 million to modernize equipment for monitoring U.S. volcanoes and improve warning systems.

The United States and its territories have 169 active volcanoes, and 54 of them need improved monitoring so scientists can warn the public about explosive disruptions, alert aircraft to ash clouds and inform communities of falling ash, lava and mud flows. March 22 eruption of the Mount Redoubt volcano, 106 miles southwest of Anchorage, Alaska, showed the need for adequate monitoring.When the Redoubt volcano erupted 19 years ago, a Boeing 747 passenger airliner flew into its ash cloud and nearly crashed.
