Timelapse view of lava moving on the plains near Pu’u O’o, Hawaii. The hill in the distance is called the “Pali”, it is the mark of a large normal fault created by part of the island sliding out towards the sea. Lava cascades over the Pali on its way to the ocean during the eruption. This is substantially sped up from how fast Pahoehoe lava typically flows.
The US National Science Foundation shared this vine showing how scientists actually sample active lava flows on Hawaii - they literally pull the lava away with a hammer then drop it in a bucket of water nearby.
