Loma Prieta earthquake hit the San Francisco Bay Area on October 17, 1989 at 5:04 PM local time. This corresponds to 0h 4m 15s UTC (October 18, 1989).
Primary seismic waves (P waves) from such events are longitudinal waves that travel through the Earth's crust.
P waves were detected at Caracas, Venezuela at 0h 13m 54s UTC. The distance traveled by the waves from Loma Prieta to Caracas was 6280 km.
If the average density of the Earth's crust is 3.3 g/cm3, what is the bulk modulus of the Earth's crust along the path traveled by the waves? Give your answer in 1011 Pa.
