Inside the technology keeping watch over Washingtons active volcanoes

The Cascades Volcano Observatory in Vancouver, Washington, is leading the charge in monitoring the seismic activity of the state's five active volcanoes, utilizing advanced technologies to alleviate resident fears of eruptions. Scientists rigorously test seismometers for reliability before deploying them in challenging mountainous locations, as emphasized by Jon Major, the Scientist-In-Charge. The Observatory’s seismometers are designed to detect even the slightest ground vibrations, ensuring they can effectively measure local earthquakes and other disturbances. Complementing this effort is the use of infrasound sensors, which capture soundwaves generated by volcanic activity that are inaudible to humans, providing an additional layer of monitoring. The combination of these technologies allows researchers to gather critical data about potential volcanic events, including those that might lead to eruptions.

The remote monitoring stations are equipped with solar panels and batteries, ensuring they can transmit real-time data back to the Observatory. This proactive approach to seismic monitoring is key in a region known for its geological activity, reassuring the local population. Although the installation of new sensors at Glacier Peak is delayed, ongoing testing remains essential to maintaining an effective monitoring system.
