Environmental Vibration Studies at Charminar

Measurement of vibrations caused by vehicular traffic around Charminar, a monument at Hyderabad, was carried out using three component velocity sensors and high-resolution digital seismograph. These measurements were done at different levels viz., ground, middle, top level and at other accessible levels of the structure. Acceleration and displacement were computed from the velocity-time series. Peak particle velocity was found maximum at the top level in the north-south direction.
