Detailed Description

At 9:17 a.m. HST, another explosive ash column rose from the Overlook Vent in Hale-ma'uma'u Crater producing a larger and darker plume. This second plume lacked the pink iron-altered ash that was in the first, and included more unaltered lithic material making it darker. This plume also was probably caused by a rock fall rather than an interaction with ground water.
