Tracking Ongoing Kilauea Eruptions -- fissures...fountains...and flows

• Spectacular Kilauea eruptions have produced a summit lava lake, roiling for several years, and a flank eruption recently sending lava flows downslope to threaten residential areas
• How do USGS scientists monitor and track subsurface molten rock movement, measure the state of volcanic unrest, and forecast eruptions?
• Hawaiian volcano "plumbing systems" force deep molten magma into subsurface reservoirs, through eruptive fissures, and onto the surface to form large lava flows
