Infrared surveys of Hawaiian volcanoes

Fischer, W; Moxham, R

'Kilauea, on the island of Hawaii, has been one of the most active volcanoes in historic time. Though it has been studied intensively since establishment of the Hawaiian Volcano Observatory in 1912, little is known of the thermal regime, despite its obvious importance in volcanic processes . . . Obvious surficial thermal anomalies are associated with Kilauea, as visible steaming in many places attests to convective transfer of heat from subterranean sources. Ground adjacent to these steaming cracks commonly is abnormally warm. But the relative intensity and spatial configuration of the thermal patterns of this extensive volcanic system cannot easily be recorded by conventional means. Modern infrared imaging radiometers have enabled us to map the distribution of anomalies associated with Kilauea and Mauna Loa, including some that have later been sites of volcanic eruption. These instruments have also made it possible to locate fresh water springs discharging into the ocean and to demonstrate relationships between surface configuration and consolidation and infrared emission that warrant further study, because of their possible application to lunar and planetary investigations.'
