March 25, 2024 — Annual Kīlauea gravity survey

Detailed Description

A volcano observatory scientist and a collaborator carry the gravity survey instruments across spatter deposits from the September 2023 Kīlauea summit eruption. Only one benchmark survived the September eruption; comparing data collected there during previous surveys to data collected there during the recent survey will allow the scientists to see changes over time.
