STATEMENT FOR THE RECORD
COMMITTEE ON ENERGY AND NATURAL RESOURCES
UNITED STATES SENATE
JUNE 17, 2009
Mr. Chairman and Members of the Subcommittee, thank you for this opportunity to provide testimony on Senate Bill 782, which is "to provide for the establishment of the National Volcano Early Warning and Monitoring System".The Department would like to thank the Committee for its work on the bill, which recognizes a number of activities that USGS currently conducts under existing authorizationsThe USGS operates a system of five Volcano Observatories for the purpose of reducing losses of life and property and minimizing social and economic disruptions during volcanic eruptions and their often protracted precursory phases. The USGS does this under the Disaster Relief Act (P.L. 93-288, popularly known as the Stafford Act) as the lead Federal agency with responsibility to provide notification for earthquakes, volcanic eruptions, and landslides to enhance public safety and to reduce losses through effective forecasts and warnings based on the best possible scientific information.
Volcanoes produce many kinds of destructive phenomena.In a few recent cases within the
Hazardous volcanic activity will continue to occur, and the ongoing exposure of human life and enterprise will continue to be a primary consideration driving USGS volcano monitoring efforts.Fortunately, volcanoes exhibit precursory unrest that if detected and analyzed in time allows eruptions to be anticipated and communities at risk to be forewarned with reliable information in sufficient time to implement response plans and mitigation measures.
Monitoring volcanic activity in the
The Volcano Hazards Program also maintains an international rapid-response team under the Volcano Disaster Assistance Program (VDAP), co-funded by the U.S. Office of Foreign Disaster Assistance within the U.S. Agency for International Development (USAID).This team responds to emergencies worldwide when called upon by the U.S. Department of State and also works to build volcano observatory infrastructure in other countries that are subject to volcanic disasters.Through VDAP, the USGS and its partners gain experience with a broad spectrum of volcano behavior and participate in disaster response and mitigation activities in a variety of physical and cultural settings, all of which inform and improve our domestic volcano-response capabilities.
The USGS works closely with other Federal agencies that contribute to volcano monitoring.The National Science Foundation has funded installation of geophysical instruments to detect ground deformation at about a dozen volcanoes for research projects through its EarthScope Program.Operational environmental satellites operated by the National Oceanic and Atmospheric Administration (NOAA) provide important global remote-sensing data used by the Volcano Observatories to complement ground-based networks,NOAA also operates two of eight Volcanic Ash Advisory Centers (
Rationale for a National Volcano Early Warning and Monitoring System
We have learned from hard experience that waiting to deploy a robust monitoring effort until a hazardous volcano awakens and an unrest crisis begins means that scientists, civil authorities, businesses, and citizens are caught in a reactive mode of "playing catch up" with the volcano, trying to get instruments and civil-defense measures in place before the unrest escalates and the situation worsens.Precious time and data are lost in the weeks it can take to deploy a response to a reawakening volcano – time and data that the public needs and should have to prepare for the hazards they may be confronted with.At present, 74% of the nation's moderate or high threat volcanoes are monitored by the USGS at various levels. Of the most threatening
Volcanoes do not need to erupt to cause problems. Changes in a volcano's behavior that are noted by the local population—such as increased smell of sulfur gases, steaming at the summit, or felt earthquakes—may cause an over-reaction, especially if fueled by rumors of an imminent eruption.This over-reaction may extend beyond the average citizen to corporations, small businesses, and government agencies. Without proper instrumentation installed on a volcano, it is difficult to ascertain whether activity is within the range of normal background behavior and thus of little concern or precursory to a significant eruption.In contrast, a well-instrumented volcano monitored by a local observatory coupled with an active program of community outreach can quickly replace rumors and speculation with sound scientific interpretation of the activity, thereby minimizing social and economic disruption.
The recent eruption of Redoubt volcano,
In 2005 the USGS published "An Assessment of Volcanic Threat and Monitoring Capabilities in the
The 2005 assessment prioritized volcanic centers where monitoring improvements should be upgraded: 13 in Washington, Oregon, and California, 3 in Hawaii, 1 in Wyoming, 28 in Alaska (where many active volcanoes have no ground-based monitoring yet pose a significant threat to aviation), and 8 in the Northern Mariana Islands (also an area with significant hazards to aviation from unmonitored volcanoes).
The 2005 report also recommended a number of other steps beyond instrumentation improvements, including easier access to monitoring data, improved hazard-information products for decision-makers and the public, enhanced collaboration between USGS and external researchers, and innovative outreach to help communities develop risk-wise practices.
Currently, the USGS is authorized to implement all of the recommendations contained in NVEWS Report under the Stafford Act. After publication of the initial report in 2005, USGS began taking steps to implement some of the Report's recommendations. In 2009, USGS plans to finalize a strategy to achieve the recommendations of the report. NVEWS-recommended upgrades planned for the upcoming year include upgrades to monitoring capabilities at Newberry and Crater Lake volcanoes in Oregon.Furthermore, $15.2 million in funding under the American Recovery and Reinvestment Act will be used primarily to modernize existing monitoring equipment at Kilauea and Mauna Loa volcanoes in Hawaii, at Anatahan and Sarigan volcanoes in the Northern Mariana Islands, at Yellowstone Caldera in Wyoming, and at Spurr, Redoubt and Augustine volcanoes in the Cook Inlet of Alaska; the software and communication systems used to transmit data from that equipment also will be modernized.Additionally, ARRA funds will be used to produce high-resolution topographic maps of volcanic areas in the Pacific Northwest that will greatly aid in development of volcanic-hazard mitigation plans by local communities. S.782 would authorize $15 million in additional funding to implement NVEWS, which has been adopted as USGS policy for volcano hazards in "Facing Tomorrow's Challenges - U.S. Geological Survey Science in the Decade 2007-2017" (USGS Circular 1309).
Elements of the National Volcano Early Warning and Monitoring System (NVEWMS)
1.Improved monitoring infrastructure – targeting the volcanoes that are significantly under-monitored for the threats posed. This will be done principally in Alaska, Hawaii, the Commonwealth of the Northern Mariana Islands, California, Washington, Oregon, and Wyoming.In addition to installation of new networks and telemetry, out-dated patchwork monitoring systems will be modernized.
2.Measures for reduced community vulnerability – supporting communities in developing plans for mitigating volcanic risk.As with earthquakes, a key to risk mitigation is preparation. This means identifying high-risk areas and community vulnerabilities, creating new hazard-information products, and continuing to build broad-based hazard awareness.
3.An external grants program – to engage the Nation's broader scientific community in advancing volcano monitoring science and technology and the societal aspects of volcanic risk mitigation.Volcanology is advancing rapidly both through growing understanding of volcanic processes and through advances in technology that make possible new kinds of observations. Many of these advances have occurred through the National Science Foundation's basic research programs and through the efforts of USGS scientists. The framework identifies a need, however, to provide support for engaging the Nation's non-federal scientists in applied volcanology, through a competitive, peer-reviewed grants process to support investigations complementary to but not duplicative of NSF-supported research.
4.Volcano Watch Office –for readily available situational awareness of current volcanic conditions.At present, Volcano Observatories mount 24/7 responses during eruption crises by drawing heavily from partners and other observatories, as well as regular daytime staff, for support.There is a danger of missing important precursors between such crises.A 24/7 Watch Office will provide backup to observatories and also serve as a single point of contact for other federal agencies such as FAA, NOAA, and the Department of Defense that require situational awareness around the globe and around the clock.
5.National Volcano Data Center – as a gateway for access to U.S. volcano data, both within the observatory system and for the external scientific community. The free exchange of data both within the observatory system and to the broader scientific community and public is fundamental to scientific advancement, risk mitigation, and government transparency.
The USGS will not carry out NVEWMS by itself, but will build on its long record of successfully partnering with diverse groups that have expertise and data to share in the mission of helping people co-exist with dangerous volcanoes.Our partners range from the international and national levels, such as with the U.S.A.I.D., the Air Force Weather Agency, NOAA, and the Federal Aviation Administration to the regional and local scale with neighboring universities and State agencies that are part of the structure of the Volcano Observatories.Using our strategic partnering approach, the USGS will continue to apply to new efforts to implement a National Volcano Early Warning and Monitoring System.
Key Outcomes of NVEWMS implementation:
The key outcome of NVEWMS will be to strengthen the scientific contribution to risk mitigation.Comprehensive monitoring of the Nation's most hazardous volcanoes, coupled with greater understanding of volcanic processes, will improve forecasts of the onset, intensity, duration, and effects of expected hazards.New hazard-information products and dissemination methods will be developed by close collaboration between scientists and users.Timely and accurate warnings to en-route aircraft will help prevent dangerous encounters with volcanic ash while minimizing costly unnecessary rerouting of aircraft.Overall, civil authorities, businesses, and individuals at risk will have more time and better information to prepare, ensuring that their ability to respond will not lag behind the evolving behavior of a volcano.Volcanic unrest does not always culminate in eruption, and long-term volcano monitoring will provide sound, ongoing, scientific information throughout episodes of unrest so that problems related to over-reacting or under-reacting will be minimized.
More than a network of instruments, NVEWMS will connect the monitoring and research results of scientists to the needs of decision-makers at the national to local level so that the impact of volcanic activity on the Nation is minimized.The real needs of diverse types of users will be ascertained and addressed to ensure that scientific advances are effectively applied in the real world.
The USGS appreciates the Committee's support for NVEWS, which is of the utmost importance to our nation's ability to respond successfully to future volcano hazards. We note that this funding would have to compete with existing priorities within the USGS. Additionally, we are concerned that the 5-year management plan required in Section 4 of the proposed legislation requires pre-decisional budget and planning information up to five years in advance.
As the Nation continues to face significant threats from volcanic hazards in the future, the USGS will work to address the recommendations of the 2005 NVEWS report. The Survey has an exceptional record, both nationally and internationally, of scientific accomplishment in applied volcanology and we will continue to move forward with our efforts to upgrade volcano monitoring capacity for those areas which have been judged to be the highest priority.
Mister Chairman, this concludes my remarks. I will be pleased to answer any questions you may have.
