The intensity of a particular earthquake wave is measured to be 1.9MW/m2 at a distance of 49.0 km from the source. What was the intensity when it passed a point only 1.1 km from the source? Give your answer in giga Watts per square metre, where 1GW/m2=1,000MW/m2=1,000,000,000W/m2. Assume the energy is radiated uniformly in all directions.
