HVO scientists continue to monitor Kīlauea's summit lake on near-daily trip

Detailed Description
HVO scientists continue to monitor Kīlauea's summit lake on near-daily trips. A laser rangefinder is used to measure the distance between the lake surface and the person holding the laser rangefinder on the crater rim, allowing the slow rise of the crater lake to be tracked through time.
