The active flow front continues to advance to the northeast, in the general direction of Pāhoa Marketplace. This morning, the leading tip of the active flow was 1.5 km (0.9 miles) from Pāhoa Marketplace, as measured along the path of steepest descent. Over the past week, the flow front has advanced approximately 2 km (1.2 miles), which equates to an average advance rate of 285 meters per day (roughly 0.2 miles per day) over that period.
