Rime ice coats telemetry system at Mount St. Helens.

To monitor volcanoes, scientists rely on remote monitoring equipment that can operate 24-hours a day and 365-days a year to deliver real-time data. When scientists design and install monitoring stations, they must consider the remoteness of sites, terrain, and winter conditions. Here, rime ice coats a telemetry system that transmits data near Mount St. Helens, Washington

Colombia–USA Bi-national Exchange

One of the most tragic volcanic events of the 20th century occurred in Colombia, in 1985, when an eruption of Nevado del Ruiz produced lahars that swept down river valleys and destroyed communities in its path. Over 20,000 people perished. Mount Rainier and other volcanoes of the Pacific Northwest’s Cascade Range are similar to Nevado del Ruiz in many respects—massive
