March 2024 — Hualālai GPS Survey

Detailed Description

During March of 2024, HVO is conducting a GPS survey of Hualālai volcano. This survey, usually done every three years, hasn't been conducted since 2015 due to eruptions at Kīlauea and Mauna Loa, the pandemic, and staff/personnel rotations. In this photo, HVO staff deploy a campaign GPS unit at station KEHU on Ka'upulehu crater (elevation 1894 m or 6213 ft) on Hualālai's northwest rift. This station is near the source vent for Hualālai's most recent eruption, in 1800–1801. USGS photo by A. Flinders.
