Hawaiʻi Hot Lava

After slowly moving downslope from Kīlauea Volcano’s East Rift Zone since June 27, 2014, this active lava flow in Hawaiʻi reached the town of Pāhoa just before Halloween, destroying roads, a cemetery, and private property in this community. Amazingly, the Pu‘u ‘Ō‘ō vent began erupting in 1983 and has continued erupting essentially nonstop for more than 31

Thomas Jaggar, the first director of the Hawaiʻian Volcano Observatory, from 1912-1940, probably never imagined that the gas compositions he measured in 1918-19 at the summit of Kīlauea Volcano would have such far-reaching applications in the future.

As we await the next eruption of Mauna Loa, some HVO scientists have been looking at old eruption records which enable us to see trends that could help forecast the next eruption. We can discover important patterns of eruptive phenomena, such as where earthquakes occurred and how severe they were, whether there was anomalous steaming, and how fast the lava flows were traveling.

The Hawaiʻian Volcano Observatory website (hvo.wr.usgs.gov) gets over half-a-million visitors a month. Most of those hits are folks checking out the daily Kīlauea eruption update page that has detailed reports and spectacularly beautiful photos of active lava (when available) taken in the early morning hours.

In the last few days, two scientists stationed at the Hawaiʻian Volcano Observatory (HVO) have packed their bags and headed for Mount St. Helens. Geologist Rick Hoblitt is helping to install a radar system that will allow scientists to track ash plumes from Mount St. Helens at night or during rotten weather, when there is no visibility.
