Slowly advancing flows on the coastal plain...
Lava continued to slowly advance across the coastal plain today, and was still about 1.4 km (0.9 miles) from the ocean. This photo shows a good example of "blue glassy" pāhoehoe on the coastal plain. Blue glassy pāhoehoe is a particular type of lava that is typically seen breaking out from the base of tumuli (as it is here), and represents lava that has been stored within the flow interior for a day or more. Its dense outer layer tends to be more gas-poor than typical pāhoehoe. In the upper right of the photo, a line of fume sources marks the path of the lava tube coming down the pali through Royal Gardens subdivision.
