USGS scientists plan campaign hydrophone deployment near Bogoslof volcano, Alaska

In April, USGS Alaska Volcano Observatory scientists will deploy two hydrophones near Bogoslof volcano to record eruptive activity, which has been in a state of elevated volcanic unrest since December 21, 2016. The hydrophones will be on loan from the NOAA Pacific Marine Environmental Laboratory in Newport, Oregon, and are capable of continuous recording for over 18 months. AVO has no ground-based volcano monitoring equipment on Bogoslof volcano. The nearest seismic and infrasound monitoring stations are over 50 km (30 mi) away on nearby islands, so these local recordings will provide valuable information on the shallow submarine activity from Bogoslof.



Scientists from Japan work with USGS and VDAP to improve volcano disaster prevention measures

In early March, a delegation of Japanese officials met with scientists of the USGS-Cascades Volcano Observatory and Volcano Disaster Assistance Program to learn more about the National Incident Management System (NIMS), a FEMA program that can be called upon to respond to disasters in the US. The group discussed the NIMS organizational structure and how it might supplement Japan's current warning and evacuation systems and emergency response measures.
