The Geological Survey of India has identified Thiruvananthapuram as a moderately earthquake-prone urban centre and categorised the metropolis in the Seismic III Zone. Thiruvananthapuram lies on the shores of Karamana and Killi rivers. Vellayani, Thiruvallam and Aakulam backwaters lie in the city. The soil type in the middle part of the city is a dark brown loamy laterite soil high in phosphates. Laterisation is a result of the heavy rainfall and humid conditions. In western coastal regions of the city, sandy loam soil is found, and on hilly eastern parts of the district, rich dark brown loam of granite origin is found.
