Abstract: Coastal areas are vulnerable to various hazards, such as storm surges, inundation from sea-level rise or coastal flooding, tsunamis, and more. The situation becomes particularly disastrous if the coast is densely populated and highly developed. Pakistan has a coastline stretching 1,046 km, with Karachi being the most developed part. The Karachi coast faces frequent storms during the monsoon season and is also threatened by rising sea levels in the coming years. Additionally, Pakistan's coastline is near the boundaries of two major tectonic plates—the Indo-Australian and Eurasian plates—as well as two minor plates, the Arabian and Iranian plates. In the event of a major earthquake in the Arabian Sea, a tsunami could pose a significant threat, potentially engulfing important and densely built-up commercial, residential, industrial, and sensitive military areas. This study aims to analyze potential losses due to inundation of the Karachi coast using Remote Sensing and GIS techniques.
