A vigorous channelized breakout on the flow, a short distance upslope of the leading tip of activity.

This image was acquired yesterday (December 1, 2014) by the WorldView 2 satellite, and shows the activity in the downslope portion of the June 27th lava flow. The portion of the June 27th lava flow that entered Pāhoa in October is inactive, but a new lobe is advancing downslope a short distance west of the earlier flow.

The breakouts that began about two weeks ago near the area of ground cracks continued to advance downslope over the past week, creating a new lobe on the June 27th lava flow. This lobe is a short distance west of the earlier portion of the June 27th flow that reached Pāhoa.

A closer look at the narrow lava channel near the leading tip of the active lobe. The channel consists of both open sections as well as sections that are crusted over.

This map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of the June 27th lava flow. The area of the flow on November 24, 2014, at 12:00 PM is shown in pink, while widening and advancement of the flow as mapped on December 1 at 11:30 AM is shown in red.

A small breakout was also active on the upslope portion of the June 27th lava flow. The pāhoehoe lava was flowing over an ‘A‘ā flow from late 2007.

The normal photograph is partially obscured by smoke from vegetation burning, but the thermal image can "see" through the smoke to show the nature of the channel in detail.

The thermal image shows the location of active pāhoehoe lobes scattered over the area of the breakout, with activity slowly advancing downslope towards the north (right side of images).

When Pu‘u ‘Ō‘ō began to form in 1983, the ground surface on which it was built was at an elevation of about 720 m (~2,360 ft). The Pu‘u ‘Ō‘ō cone eventually reached a height of 255 m (837 ft), putting its top at an elevation of about 975 m (~3,200 ft).
