Abstract. The towns of Pasni and Ormara were the most severely affected by the 1945 Makran tsuami. The water inundated almost a kilometer at Pasni, engulfing 80 % huts of the town while at Ormara tsunami inundated two and a half kilometers washing away 60 % of the huts. The plate boundary between Arabian plate and Eurasian plate is marked by Makran Subduction Zone (MSZ). This Makran subduction zone in November 1945 was the source of a great earthquake (8.1 Mw) and of an associated tsunami. Estimated death tolls, waves arrival times, extent of inundation and runup remained vague. We summarize observations of tsunami through newspaper items, eye witness accounts and archival documents. The information gathered is reviewed and quantized where possible to get the inundation parameters in specific and impact in general along the Makran coast. The quantization of runup and inundation extents is based on a field survey or on old maps.

Short summary
The study summarizes the historical accounts, eyewitness accounts and newspaper items to report the impact of the 1945 tsunami along the Makran coast of Pakistan. A field survey conducted along Gwadar, Pasni and Ormara quantifies inundation parameters along the three cities, using the landmarks reported in eyewitness accounts and newspaper items. The quantization of runup and inundation extents is based either on the field survey or on old maps.
