May recognized as volcano preparedness month

May is Volcano Preparedness Month in Washington, providing residents an opportunity to become more familiar with volcanic risk in their communities and learn about steps they can take to reduce potential impacts.

For Volcano Preparedness Month, there will be multiple opportunities for public engagement. A full schedule of events is online. Here are some highlights:

On Wednesday, May 9 at 10:30 a.m. PDT, U.S. Geological Survey Cascades Volcano Observatory Scientist-in-Charge Seth Moran will deliver a State-of-the-Cascades report to begin a Live Facebook Chat session. Visit USGS Volcanoes on Facebook for more information. 

(See Washington Governor Jay Inslee's proclamation for 2018 Volcano Preparedness Month)

On May 12 from 10 a.m. to 5 p.m., the USGS–CVO will host a free, family-friendly, one-day public open house. Visitors can speak with scientists, tour labs and test their knowledge of volcano hazard zones and volcano safety. The public is invited to bring a favorite mystery rock to be identified by a geologist. Displays and demonstrations offer a sampling of work that happens daily at USGS–CVO.

On May 15, from 1 p.m. to 3 p.m., Washington Emergency Management Division will sponsor a Reddit “Ask-me-Anything,” with a focus on Cascade Volcanoes. A team of experts in volcanology, geology and preparedness will be on hand to answer any questions about our volcanoes that the internet community may ask them. Feel free to follow along.

Mount St. Helens’ Eruption Anniversary

On Sunday, May 18, 1980, at 8:32 a.m., the bulging north flank of Mount St. Helens slid away in a massive landslide. Seconds later, the uncorked volcano exploded and blasted rocks horizontally, destroying centuries of forest growth in a span of several minutes. Nine hours of explosive volcanic activity ensued, forever altering the landscape and what we know about volcanoes.

The Washington Military Department’s Emergency Management DivisionWashington Department of Natural Resources, the Pacific Northwest Seismic Network (PNSN) at the University of Washington and the U.S. Geological Survey Cascades Volcano Observatory work together to provide timely warnings and reduce the negative impacts of future eruptions. Together, the agencies develop and exercise emergency plans with communities, coordinate communications, conduct public education programs and plan for short- and long-term recovery in the event an eruption or lahar should occur.

Keeping up with volcanoes - local resources

The USGS Cascades Volcano Observatory website has information about Volcano Preparedness Month events, as well as the USGS volcano-monitoring program and the hazards in the Washington and Oregon. Register for weekly updates and occasional information statements from the USGS Volcano Notification Service. Find information updates about volcanoes and read about science in action at USGS Volcanoes on Facebook.

Washington state’s Emergency Management Division website contains a section about the state’s volcanoes and volcano preparedness measures. Educational materials for children, families and communities are found in the publications section. Follow the agency’s Twitter feed, and Facebook page for breaking news and information. The Washington Geological Survey (a division of the Washington State Department of Natural Resources) has developed a website that covers all aspects of Washington geology. They also have a volcano-specific webpage.  Check out their Geologic Information Portal to learn about the hazards where you live, work, and play.

Preparing for future eruptions

The USGS–CVO, the PNSN, and the National Science Foundation-funded EarthScope Plate Boundary Observatory work to improve eruption forecasting and warning capabilities for Cascade volcanoes as part of the National Volcanic Early Warning System.

Our Reddit AMA team:

Hello Reddit!
In Washington state, we’re three days away from the anniversary of the 1980 Mt. St. Helens eruption. And with everything happening in Hawaii, we figure your volcanoes might be on your mind. We’re here primarily to answer your West Coast volcano questions, but will answer anything else we can.
We’ve assembled a team of scientists and support staff ready to field your questions.
We’re all using the same account and we’ll be signing off with our first names after the responses.
Our speakers come from the Cascades Volcano Observatory in Vancouver, Wash.  and Washington Emergency Management Division at Camp Murray, Wash.  Learn more about the CVO here: https://volcanoes.usgs.gov/observatories/cvo/cvo_about.html
