These photos of volcanic activity at Kilauea depict:


a 3 m-wide lava channel,

a leaky tumulus,

and an active pahoehoe tow

    The daily activities of the volcano (e.g., movement of lava flows, earthquakes, surface deformation and gas production) are monitored by the staff of the U.S. Geological Survey at the Hawaiian Volcano Observatory (HVO). T.A. Jagger founded HVO in 1911 and laid the foundation for all current studies of active Hawaiian volcanoes. Kilauea has been monitored ever since, making it one of the better studied volcanoes. Still there is much that we still do not understand about the inner workings of this volcano.
    Many of the members of Hawaii Center for Volcanology are working on Kilauea or have gained insights into the nature of volcanoes from visiting it. Unlike most other active volcanoes, Kilauea is approachable. It has been called the "drive-up" volcano because of the ease of access to many of its areas of volcanic activity, especially the summit caldera.

    We encourage you to take some of the 'virtual' field trips of Kilauea's summit and the Chain of Craters road that are available on SOEST's internet site through the NASA Virtually Hawaii Project
