Consortium of US Volcano Observatories - Alaska, Cascades, Hawaii, Long Valley, Yellowstone

"CUSVO - the Consortium of U.S. Volcano Observatories - is a scientific working group established in 2002 to strengthen interaction and communication among federal, state, and academic representatives of the 5 U.S. volcano observatories: the Alaska Volcano Observatory (AVO), Cascades Volcano Observatory (CVO), Hawaiian Volcano Observatory, the Long Valley Observatory, and the Yellowstone Volcano Observatory (YVO). The purpose of the Consortium is to enhance scientific and technical coordination on operational and research matters that are of broad, mutual concern among the observatories."

The United States has abundant volcanoes, and over the past 25 years the Nation has experienced a diverse range of the destructive phenomena that volcanoes can produce. Hazardous volcanic activity will continue to occur, and - because of increasing population, increasing development, and expanding national and international air traffic over volcanic regions - the exposure of human life and enterprise to volcano hazards is increasing.
From: NVEWS - a National Volcano Early Warning System

Volcanic-ash hazards to aviation are a significant factor addressed in the proposed National Volcano Early Warning System (NVEWS). Installation of monitoring networks on unmonitored and under-monitored active volcanoes that are potential threats to U.S. (both commercial and military) and international air traffic is a primary goal of NVEWS. On March 16th, 2006, the U.S. Senate Commerce, Science, and Transportation Committee's Subcommittee on Disaster Prevention and Prediction held a hearing on Volcanic Ash and Aviation Safety. The hearing contains testimony from CUSVO representatives Dr. John Eichleberger (University of Alaska Fairbanks, Coordinating Scientist for the Alaska Volcano Observatory) and Dr. James Quick (USGS Volcano Hazards Program Coordinator on the nature of the problem, and testimony from Capt. Terry McVenes of the Air Line Pilots Association (ALPA) on the commercial airline pilot's perspective of the issue. Subcommittee members Ben Nelson (D. Nebraska) and Ted Stevens (R. Alaska) also submitted statements in recognition of this national and international hazard.

Summary of the Stakeholders Workshop to Develop a National Volcano Early Warning System (NVEWS)
"The NVEWS report identified the need to convene a workshop of a broad group of stakeholders - such as representatives of emergency- and land-management agencies at the Federal, State, and local levels and the aviation sector - to solicit input about implementation of NVEWS and their specific information requirements. Accordingly, an NVEWS Stakeholders Workshop was held in Portland, Oregon, on 22-23 February 2006. A summary of the workshop is presented in this document."
