- Abstract: Automatic recognition and segmentation methods now become the essential
requirement in identifying co-seismic landslides, which are fundamental for
disaster assessment and mitigation in large-scale earthquakes. This approach
used to be carried out through pixel-based or object-oriented methods. However,
due to the massive amount of remote sensing data, variations in different
earthquake scenarios, and the efficiency requirement for post-earthquake
rescue, these methods are difficult to develop into an accurate, rapid,
comprehensive, and general (cross-scene) solution for co-seismic landslide
recognition. This paper develops a robust model, Dense Feature Pyramid with
Encoder-decoder Network (DFPENet), to understand and fuse the multi-scale
features of objects in remote sensing images. The proposed method achieves a
competitive segmentation accuracy on the public ISPRS 2D Semantic. Furthermore,
a comprehensive and widely-used scheme is proposed for co-seismic landslide
recognition, which integrates image features extracted from the DFPENet model,
geologic features, temporal resolution, landslide spatial analysis, and
transfer learning, while only RGB images are used. To corroborate its
feasibility and applicability, the proposed scheme is applied to two
earthquake-triggered landslides in Jiuzhaigou (China) and Hokkaido (Japan),
using available pre- and post-earthquake remote sensing images.

We introduce DAVI (Disaster Assessment with VIsion foundation model), a novel approach that addresses domain disparities and detects structural damage at the building level without requiring ground-truth labels for target regions.
DAVI combines task-specific knowledge from a model trained on source regions with task-agnostic knowledge from an image segmentation model to generate pseudo labels indicating potential damage in target regions.
It then utilizes a two-stage refinement process, which operate at both pixel and image levels, to accurately identify changes in disaster-affected areas.
