Question

12.An earthquake generates both transverse (S) wave and longitudinal (P) wave in earth crest. The speed of S waves is about 4 km per sec. and that of P waves is about 8 km per sec. A seismograph records P and S waves from an earthquake. The first P wave arrives 5 minute earlier than the first S wave. The epicentre of earthquake is located at a distance of about 1200 km 2400 km 1600 km 1920 km

Q. On December 2006, a great earthquake occurred off the coast of Sumatra and triggered immense waves (Tsunami) that killed some 200,000 people. Satellites observing these waves from space measured 800 km from one wave crest to the next and a period between waves of 1 hr. what was the speed of the wave?
