Rapid mapping of volcanic eruption building damage: A model based on prior knowledge and few-shot fine-tuning

Zeyu Wang, Feng Zhang, Chuyi Wu, Junshi Xia

Abstract: Highlights•A Siamese CNN model with prior knowledge is used to identify building damage.•Few-shot fine-tuning method enables the model to adapt to volcanic scenarios.•Samples from cross-domain disasters are used to validate the model’s effectiveness.•Building damage statistics are potential in post-eruption environmental assessment.
