Volcano Watch: A new eruption and new era at Kilauea Volcano

‘Twas the Sunday before Christmas, the eve of the winter solstice, and festive holiday lights blinked of bright red and green. And then, shortly after 9:30 p.m. on Dec. 20, so did the Hawaiian Volcano Observatory’s volcano alert level/aviation color codes for Kilauea!

Volcano Watch: How has topography been modeled at Hawaii’s volcanoes?

In cartography and geographic analyses related to volcanoes, especially in Hawaii, there is perhaps nothing more important than having an accurate digital model of topography. Such models depict the three-dimensional nature of the land, elucidating features from past eruptions and influencing potential pathways of future activity.

Crack team of geologists measure the Koa‘e fault system

The Koa‘e fault system connects Kilauea’s East and Southwest rift zones south of the caldera. Faults here appear as low cliffs, or “scarps,” along Hilina Pali Road in Hawaii Volcanoes National Park. These fault-cliffs slip during major earthquakes, such as those of May 4, 2018 — near the beginning of Kilauea’s 2018 eruption.

Volcano Watch: HVO camera network reconfiguration and upgrades coming soon

Throughout the past two decades, the USGS Hawaiian Volcano Observatory has set up a camera network system to monitor visual changes at Kilauea and Mauna Loa volcanoes. This network was designed for the volcanic activity of the time and captured the two long-lived eruptions of Kilauea at the summit and East Rift Zone up close.
