Active basaltic lava flow in Hawaii Volcanoes National Park. In
foreground, molten lava flows out of crack in uplifted surface crust and
fills surrounding low-lying region. Background shows path of lava flows
through forest on cliffs stepping down toward coastal plain. The current
eruption began in 1983 and continues to build a large lava flow field
that extends for more than 10 km from Kilauea Volcano's east rift zone
toward the Pacific Ocean. PSI's David Crown, along with Mike Ramsey of
the University of Pittsburgh, Jeff Byrnes from the University of North
Dakota, and Steve Anderson of Black Hills State University, traveled to
Hawaii to conduct field and remote sensing studies of this and other
lava flow fields as
analogues for those on the surfaces of Mars and Venus. Photograph taken
on 1/15/03 by David A. Crown.
