As inflation occurs within the core of a pāhoehoe flow, a tumulus (http://volcanoes.usgs.gov/images/pglossary/tumulus.php), or domed hill, can form.

A view looking along the transfer station's outer fence, which lava burst through recently. Lava then flowed down the embankment onto the low access road (right side of photo).

This large-scale map shows the distal part of the June 27th flow in relation to nearby Puna communities. The area of the flow on November 10 at 10:45 AM is shown in pink, while widening and advancement of the flow as mapped on November 12 at 7:00 AM is shown in red.

The small breakout near the solid waste transfer station began spilling into the truck access road that loops around the transfer station. This road is quite a bit lower than the transfer station buildings, and it will likely take a few days for it to fill up, if the breakout remains active.

Lava flows continue to encroach on the Pāhoa Japanese Cemetery, with the latest activity there coming right up to the edge of the green-roofed shelter.

This map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base at 1:13,000 scale to show the area around the front of the June 27th lava flow. The area of the flow on November 10, 2014, at 10:45 AM is shown in pink, while widening and advancement of the flow as mapped on November 12, at 7:00 AM is shown in red.

Lava continues to advance downslope in several places along the distal part of the June 27th lava flow, as seen in this photo. The most active breakout is the flow to the right, which forms a relatively narrow finger about 360 meters (390 yards) upslope from AP‘A‘ā Street.

This photo shows the distal part of the June 27th flow looking toward the southwest. The stalled tip of the flow is barely cut off at the left side of the photo.

A comparison of a normal photograph with a thermal image of the leading tip of the June 27th flow. The stalled flow front exhibits lower surface temperatures (red, purple colors), as it has been stalled for over a week. Upslope, however, scattered breakouts are active and have much higher surface temperatures (white, yellow colors).

Another view of the activity near the transfer station, shown by a normal photograph and a thermal image. The white arrows show corresponding points of reference. The left arrow marks the tip of this small lobe (one of many active today), which was approaching AP‘A‘ā St.

The house which was recently destroyed by lava is just below the center of the photo. Lava bypassed the garage, which still stands at the center of the photo. Lava briefly entered the fish pond next to the house, before continuing downslope.

Inflation is a common characteristic of active pāhoehoe flows. Here, a flow has inflated up to the level of the Pāhoa transfer station fence. A glowing crack provides evidence of the flow's molten interior.

Just before noon, HST, on Tuesday, November 11, 2014, lava pushed through the fence at the southwest corner of the Pāhoa transfer station and moved down the slope onto the station grounds. The flames are caused by burning asphalt.

The flow lobe that destroyed a residence on Monday has also inflated significantly. Here, an HVO geologist examines the margin of that lobe. A barbed wire fence was surrounded and tilted towards the camera as the flow inflated, so that the fence is now nearly horizontal. The red roof in the background is the garage structure near the house that burned on Monday.
