Terminus of the flow entering the Pāhoa transfer station. Compare to a similar image taken on November 11. There are no active toes of lava in the image, but the lava is still hot enough to burn the asphalt beneath, creating visible white smoke.
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. Occasionally the pressure within the flow can exceed the strength of the pāhoehoe crust, resulting in an outpouring of lava from the core of the tumulus. Lava burst from this tumulus, left side of photo along the skyline, approximately 35 yards downslope of the cemetery. A rocky block, presumably from the top of the tumulus, rests where the outpouring of lava began.
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).
