Challenge Problems
Push your limits with advanced challenges
Consider the 2004 Indian Ocean earthquake and its tsunami. Using mathematical modeling, estimate the energy release in joules based on its moment magnitude (Mw) and compare it to smaller quakes.
💡 Hint: Understand that an increase of 1 in magnitude corresponds to a jump in energy release by a factor of about 31.6.
Analyze the differences in response strategies adopted by Japan after the Tōhoku Earthquake compared to Indonesia after the 2004 earthquake.
💡 Hint: Consider how geography and resources influence disaster response.
