Final answer:
The wave amplitude of the earthquake is approximately 398.107 times stronger than a0.
Step-by-step explanation:
To determine approximately how many times stronger the wave amplitude of the earthquake was than a0, we can use the Richter scale formula: r = log(lambda/lambda0). In this case, the Richter scale measurement is 3.6. The formula relates the ratio of the wave amplitude (lambda) of the earthquake to the reference wave amplitude (lambda0).
By rearranging the formula, we can solve for lambda: lambda = lambda0 * 10r.
Substituting r = 3.6 and lambda0 = 1, we get: lambda = 1 * 103.6. Evaluating the expression gives us lambda ≈ 398.107.
Therefore, the wave amplitude of the earthquake is approximately 398.107 times stronger than a0.
