Earthquake resilience of Pol houses in Ahmedabad

2.4.2 Earthquake effects on Ahmedabad old city The walled city of Ahmedabad is situated on the banks of river Sabarmati. The landform of the old city is almost uniformly flat, unlike the newer city which has small hillocks, known as tekaras in Gujarati. It was observed that the walled city showed extremely low damage and no complete collapse when compared to the newer R.C. structures. According to the survey conducted by the Ahmedabad Municipal Corporation in 2001 roughly, only 10% of the structures in the old city showed major cracks and signs of damage post-earthquake. (Modan, 2006) .Randolph Langenbach also mentions in his report that only one traditional structure was completely collapsed in the old city. The analysis was also pointed out that as the city is located 400kms away from the epicenter the seismic waves were longer, hence the possibility of complete collapse of taller structures was larger. Still, comparatively the old city with traditional houses suffered little damage and no casualties were reported due to falling of structures. It was also observed that one of the traditional pol houses which suffered the collapse due to the falling of the newer R.C. structure adjacent to it. (Shah K. , 2020)
