Each level of the Richter Scale describes an increase in the energy released by an earthquake – each level increases by 32 times. a. What is the difference in energy between a 4.0 and a 1.0? b. What is the difference in energy between an 8.0 and a 3.0? 48. A tsunami caused by an earthquake in Japan (at 1:30 AM Pacific time) is travelling at 500 km/hr. San Francisco is about 8,000 kilometers from Japan. At what time will the tsunami reach San Francisco? 49. The same tsunami wave is 10 meters high on the open ocean. When it reaches San Francisco Bay, it will travel at 10 km/hr. How high will the tsunami be on land? Amplitude = √ (Open Ocean Height • (Open ocean speed) / (San Fran Bay Speed) )
