Unveiling a century of stress and deformation: Insights from K?lauea Volcano's 1975 earthquake

The article discusses a study published in the journal *Geophysical Research Letters* focusing on the 1975 magnitude-7.7 earthquake near Kīlauea volcano in Hawaii. This earthquake, which occurred on November 29, 1975, was significant as it was the largest to strike the island in modern times, causing extensive damage and triggering a tsunami. Researchers analyzed the stress and deformation changes over the past century, particularly how the earthquake altered the stress field around Kīlauea. The study utilized a combination of historical data, including seismic records, GPS measurements, and InSAR (Interferometric Synthetic Aperture Radar) to understand the long-term effects. The findings suggest that the earthquake not only changed the stress distribution but also influenced subsequent volcanic activity, providing insights into how large seismic events can impact volcanic systems. This research enhances our understanding of the interplay between tectonic and volcanic processes, aiding in better hazard assessment and mitigation strategies for regions with similar geological settings.
