A map showing the flow direction of the June 25th Lava Flow (as of November 24, 2014) In June 2014, a lava flow dubbed the June 27th flow started running from a vent in the Puʻu ʻŌʻō cone in a northeast direction towards the villages of Ka'ohe Homesteads and Pāhoa.
Pahoehoe lava is a relatively smooth lava flow that can be billowy or ropey. They can move as one sheet, by the advancement of "toes", or as a snaking lava column. [10] A'a lava flows are denser and more viscous than pahoehoe, and tend to move slower. Flows can measure 2 to 20 m (7 to 66 ft) thick.
The word lava comes from Italian and is probably derived from the Latin word labes, which means a fall or slide. [2] [3] An early use of the word in connection with extrusion of magma from below the surface is found in a short account of the 1737 eruption of Vesuvius, written by Francesco Serao, who described "a flow of fiery lava" as an analogy to the flow of water and mud down the flanks of ...
When pahoehoe lava emplaces, it sometimes form lobes. The formation of aligned pahoehoe lobes that are continuously fed by molten lava may form lava tubes. During an eruption, when lava flows emplace and their sides cool rapidly and solidify into levees, the pressure of molten lava passing through the flow may cause it to inflate.

The lava tube allowed the fluid pahoehoe lava to retain heat and flow long distances. In less than a year, overflow from the lake created a broad and low shield about 55 meters (180 ft) above Kūpaʻianahā. Lava streams were first visible from the town of Kapaʻau in November, 1986. In the course of that month, lava cut a swath through ...
