The 2021 La Palma eruption was the island's most voluminous historical eruption. Seismicity was distributed in two clusters at -10-14 km and -33-39 km depth, separated by an aseismic zone. Using seismological methods, including 8,488 hypocentral relocations and 156 moment tensors, the study suggests a long-lasting preparatory stage with the destabilization of an intermediate reservoir and a co-eruptive stage controlled by two localized reservoirs. The findings provide insights into the plumbing system for improved eruption monitoring.
