Segment of Kahuku pali reveals clues about Mauna Loa

One of the more spectacular geologic features on Hawaii Island can easily be seen from Highway 11 near South Point. It is a cliff informally known as the Kahuku pali, after Kahuku Ranch. The cliff has two Hawaiian names: Pali o Mamalu, for its mauka section, and Paliokulani, for its makai section.

Phone service providers make lava plans

It’s not known when, or even if, lava from Kilauea Volcano’s June 27 flow will reach Pahoa town or cross Highway 130, but the leading edge of the flow again started to advance over the weekend after stalling for several days. Among those using the time granted by the molten rock’s slow advance to prepare for a potential disaster are telephone service providers.

Why do lava flows stop advancing?

Much scientific study has been done to determine what types of eruptions produce long lava flows. In the 1970s, a very simple idea seemed to guide future work — the length of a lava flow is limited by either the supply of lava or by how well the lava is thermally insulated during its transport to the flow front.
