The magnitude M of an earthquake is related to the energy
Step by step
Solved in 2 steps
- A recent magnitude 6.0 Earthquake was recorded. Earthquakes represent a release of energy as a result of the earth's tectonic plates. a) Determine the amount of energy released in ergs. b) Determine the energy release in Joules. ( Hint use the earthquake formula M = 2/3 log (E/ 10^11.8); where M is the earthquake magnitude and E is the energy of the earthquake in ergs (recall 1 erg = 10^-7 Joules)).Find the intensity of an earthquake with a period of 0.03 and an amplitude of 4,000 micrometers. (Round to the nearest tenth.)This exercise uses elementary properties of the Richter Scale.One earthquake has a Richter scale reading of 6.5. Another is one-thousandth as strong. What is its Richter scale reading?
- If you become trapped inside a structure during an earthquake what should you do?earthquake intensity measured by I = Io x 10^m, Io is reference intensity and M is magnitude. An earthquake measuring 6.1 on the Richter scale is 125 times less intense than the second earthquake. What would the Richter scale measure be for the second earthquake?A wave field is observed by satellite. The wave lengths are determined to be 312 m in deep water and 200 m over the continental shelf. What is the shelf depth? (The answer posted for this question was incorrect.)
- According to the LA Times news report, a moderate magnitude 3.6 earthquake centered near the Granada Hills neighborhood occured on Jan 22, 2020. Use scientific notation in your final results to a) Refer to the Mercalli scale above to identify the intensity level, shaking and description/damage of the earthquake. b) Draw a cross sectional sketch of the earth identifying the FOCUS and epicenter of the earthquake. c) Determine the amount of energy released in ergs and d) Joules.Compare the energy released by an atomic bomb blast (magnitude 3.9) to an earthquake of 9.9 magnitude. Enter your answer in scientific notation. energy difference = × 10If the time difference between the arrival of P-waves and the arrival of S-waves is 60, approximately how far are you from the epicenter of the earthquake?
