Photo and Video Chronology - Kīlauea - August 7, 2003

Release Date:

Two last views of a skylight

 

photo of lave

Using laser gun to measure velocity of lava in master tube for Mother's Day flow. Multiplying velocity times cross-sectional area yields flux of lava in tube. The cross-sectional area is interpreted from measured differences in conductivity for very low frequency radio signals passing across the tube. This skylight, called Okita Nuevo, was filled during breakout early the next day; see middle and lower below images for August 9.

Maps of lava-flow field, Kilauea Volcano

Map shows lava flows erupted during 1983-present activity of Pu`u `O`o and Kupaianaha. Red colors, both dark and light, denote Mother's Day flow, which began erupting on May 12, 2002 and continues to the present. The darkest color represents flows active since January 21, 2003.

Most recent--and ongoing--activity has produced two flows, one along western edge of flow
