Question

To the nearest millimeter, what would be the amplitude of the seismic waves at a sensor located in Escondido, California, 150 km from the epicenter? Use a distance correction factor of -3.29 for 150 km.

(A) 1288 mm
(B) 2570 mm
(C) 4074 mm
(D) 10.233mm

Answer 1

The amplitude of the seismic waves at a sensor located in Escondido, California, 150 km from the epicenter is -494,000 mm.

Step-by-step explanation:

To calculate the amplitude of the seismic waves, we need to use the distance correction factor and the formula for amplitude. The distance correction factor of -3.29 is given for 150 km. We can calculate the amplitude using the formula:

Amplitude = Distance Correction Factor * Distance

Plugging in the values, we have:

Amplitude = -3.29 * 150 km = -493.5 km

Since the question asks for the answer to the nearest millimeter, we round the result to -493.5 km to -494 km or -494,000 mm.
