Kīlauea has had a long and active history, and each eruption provides us new insights into volcanic processes and hazards.

It takes a village to run a volcano observatory.

This belated Volcano Watch should have been written in January when David and his wife Francine Coloma, who is a scientist with the National Oceanic and Atmospheric Administration (NOAA), moved to Hilo.

"Because HVO has over 100 years of volcano monitoring experience, scientists from volcano observatories around the world are eager to visit and learn from HVO and our active volcanoes."

HVO staff, as well as scientists from other USGS observatories and UH, provide instruction and hands-on training in geophysical, geochemical, and geological methods of monitoring and assessing volcano hazards.

Hawaiian Volcano Observatory offers more resources to learn about lava flows.

Our analysis indicates that increasing pressure in the magmatic system, which far exceeds the change in pressure modeled as due to rainwater infiltration, was the primary driver in triggering the 2018 eruption.

Forty years ago, no scientists in the USGS and academia were adept at monitoring all types of active volcanoes.

The first eruption in the Cascades since 1914­–1917 (Lassen Peak) started on March 27, 1980.

Janet volunteered at HVO for many years before being hired in 2008 to help the Observatory manage public information during Kīlauea’s first summit eruption since 1982.
