Multi-temporal InSAR coherence analysis of 2023 Nyamulagira volcano activity
In this work, we analyze the 2023 Nyamulagira volcanic crisis using remote sensing Synthetic Aperture Radar (SAR) data acquired from January to June 2023 by Sentinel-1 missions. We perform a coherence variations analysis to constrain any magma movements inside the crater and lava flows along the flanks of the volcano. Outcomes reveal periodic phases of high and low volcanic activity along the entire 2023 with a strong crisis occurring in May, with lava completely filling and overflowing the caldera.
