Detailed Description
The 10 cm (4-inch) pocket knife in this image provides scale for one of the larger fragments of molten lava that was thrown onto the rim of Halema‘uma‘u Crater at 3:51 a.m., HST, on January 8, 2016. So much spatter was ejected to the crater rim this morning that it is hard to discern one lava fragment from another.
