This thermal map, which was constructed by merging about 1300 images from a morning helicopter overflight on April 8, shows the distribution of some prominent thermal features in Kīlauea's summit caldera.

Managers of water-supply lakes need an accurate estimate of the lake capacity to ensure that enough water is available for uses such as: providing consistent recreation pool levels, preserving downstream aquatic habitat, flood abatement, water supply, and power generation. Lake capacity is particularly important for managers of water-supply lakes during periods of drought, unexpected...

Mauna Loa, the largest volcano on Earth, has erupted 33 times since written descriptions became available in 1832.
