The assessment focused on flood water depth (Fig. 1) and inundation extent (Fig. 2).The flood water ...

Pakistan Flood Situation Update:18 July 2025

According to the remote sensing monitoring results from July 18, 2025, a comprehensive assessment of flood inundation across Pakistan was conducted using multi-source satellite imagery from Sentinel-1, Sentinel-2, Landsat-8, and Landsat-9 (Fig. 1). The results indicate that flood-affected areas have continued to expand, with significant inundation observed across the Indus River Basin and surro...

Floodwater Depth Situation of the Flood on July 16th

On July 16, 2025, a comprehensive flood depth assessment across Pakistan was conducted using multi-source satellite imagery from Sentinel-1, Sentinel-2, Landsat-8, and Landsat-9, integrated with the KDFIMv2 algorithm (Fig. 1). The results indicate that most inundated areas exhibited flood depths around 1 meter, while floodwaters in the main Indus River channel and the southwestern mountainous r...

Pakistan Flood Situation Update:16 July 2025

在2025年7月16日的巴基斯坦洪水遥感监测中，基于Sentinel-2、Landsat 8、Landsat-9 与 Sentinel-1 多源遥感影像，结合 KDFIMv2完成了对巴基斯坦全境 洪水淹没情况的综合评估（图1）。监测结果表明，洪水主要集中分布于信德省北 部及旁遮普省南部的印度河流域；这一地区地势相对低平，河网密集，历史上即 为洪水高风险区域。季风期间，来自上游的集中降雨和山区径流通过印度河主干 道向下游汇集，极易导致低洼平原发生广泛淹没。...

Pakistan Flood Situation Update:15 July 2025

Using multi-source remote sensing data acquired from July 15, 2025—including Sentinel-2, Landsat-8, Landsat-9, and Sentinel-1—and applying the KDFIMv2 algorithm, floodwater depth retrieval has been completed for the affected regions. Results from Fig. 1 indicate that floodwaters around the Chashma Reservoir have largely receded, with only minor residual inundation remaining. The flooded area ...

Pakistan Flood Situation Update– July 14, 2025

Using multi-source remote sensing data acquired from July 11 to 13, 2025—including Sentinel-2, Landsat-8, Landsat-9, and Sentinel-1—and applying the KDFIMv2 algorithm, floodwater depth retrieval has been completed for the affected regions. Results indicate minimal variation in floodwater depth around the Chashma and Tarbela Reservoirs, with no significant expansion of the inundated area. Howe...

Pakistan Flood Situation Update– July 13, 2025

In response to the intense rainfall event affecting Punjab, Khyber Pakhtunkhwa (KP), and Balochistan, satellite-based rapid flood mapping was conducted to assess the impacted areas on July 11, 2025.Based on the KDFIMv2 algorithm, the distribution of natural surface water prior to the flooding was derived using multi-source satellite imagery from January to June 2025, including Sentinel-2, Lands...

Wildfire Risk Mapping for Pakistan from July 14 to July 20, 2025

 数据源：VIIR VNP43MA4\VNP43IA4数据；GFS数据火险分布情况：n Balochistan省（奎达、苏拉布、米斯图恩、博兰等）风险级别：高 - 极高，特别是在Quetta以南与Surab区域集中分布火险。n 信德省（Karachi、Badin、Thatta等）风险级别：中等 - 高，Karachi以北和东部的山区及Thatta附近有明显高火险分布。Karachi市区本身风险较低，但周边林地风险较大。n 北部地区（伊斯兰堡、白沙瓦、斯卡杜等）风险普遍较低，但某些局部高山地...

Multi-dimensional Assessment of Disaster Losses and Dynamic Decision-making(灾害损失多维度评估与动态研判)

Climate-Adaptive based Cross-Region Crop Damage Assessment基于气候自适应的跨区域农作物损失评估      Using the proposed climate-adaptive cross-region mapping method (R² = 0.82), we rapidly assessed the impact of the 2021 Henan extreme flood on maize in Jiaozuo, Henan Province. The results indicate that the southern and southeastern regions of Jiaozuo suffered the most severe maize damage.  使用...

Multiple-Satellite Images Supported Road Blockage Assessment for March 21, 2024 Naran Avalanche, Pakistan

The avalanche incident occurred in Naran, northern Pakistan on March 21, 2024, which submerged houses and hotels, served as a trigger for further in-depth analysis of avalanche risks in the downstream towns and villages. Through comprehensive multi-case studies, it was found that the phenomenon of snow melting into water before heavy precipitation warrants particular vigilance, as it greatly in...
