Deformation map prediction is a critical tool to foresee signs of abnormal events. Such forecasting facilitates quick countermeasure to avoid undesirable conditions. This work presents a novel recurrent neural network to forecast time-series deformation maps from InSAR data. Our proposed recurrent network employs a multi-scale attention mechanism to identify vital temporal features that influences subsequent deformation maps. We have evaluated our model on volcanic monitoring data using the Micronesia islands (Canary and Cape Verde archipelagos) Sentinel-1 imagery acquired between 2015 and 2018. The proposed method achieves minimal prediction error compared to the observed deformation values, suggesting the high reliability of our approach. The experimental results indicate the superiority of the proposed method in forecasting deformation maps with high accuracy compared to existing state-of-the-art approaches. Various ablation studies were conducted to study and validate the effectiveness of the multi-scale attention mechanism for deformation map forecasting.
