Timelapse showing typical activity at Kīlauea's summit water lake

This timelapse video at Kīlauea's summit covers approximately 30 minutes and shows the dynamic nature of the water lake in Halema‘uma‘u crater. Steam from the hot water surface is constantly shifting in the winds, while the migrating color boundaries on the water surface appear to show circulation in the lake. USGS video by M. Patrick.

The Raspberry Shake 4D (RS4D)

The Raspberry Shake 4D (RS4D) is a personal seismograph with a vertical-component velocity transducer, and three-component (vertical, north-south, and east-west) accelerometer. A Raspberry Pi, which is a computer about the size of a credit card, powers the RS4D unit, which is about the size of a can of Spam. Advances in emerging technology are able to make scientific
