Detailed Description
Preview image for video: shows an HVO geologist sampling lava on the June 27th lava flow using a rock hammer. The lava is placed into a bucket of water to quench the sample. Lava samples like this are routinely collected for chemical analysis, which provides insight into the magmatic system feeding the eruption.
