Climate change is leading to an increase in extreme weather events causing significant environmental damage and loss of life. Early detection of such events is essential for improving disaster response. In this work we propose SITS-Extreme a novel framework that leverages satellite image time series to detect extreme events by incorporating multiple pre-disaster observations. This approach effectively filters out irrelevant changes while isolating disaster-relevant signals enabling more accurate detection. Extensive experiments on both real-world and synthetic datasets validate the effectiveness of SITS-Extreme demonstrating substantial improvements over widely used strong bi-temporal baselines. Additionally we examine the impact of incorporating more timesteps analyze the contribution of key components in our framework and evaluate its performance across different disaster types offering valuable insights into its scalability and applicability for large-scale disaster monitoring.
