How would you respond if you were a naval captain planning to enter a port within the next three hours and you received a report that a large earthquake occurred along a sea coast 3000 km away from the opposite side of the ocean?

• I will cancel the cruise of the ship with some vague way of disseminating information to the passengers because a tsunami may arise at any moment.

• I will cancel the cruise of the ship in a certain, clear manner of disseminating information to the passengers because a tsunami may arise at any moment.

• I will still go on the cruise of the ship because canceling the trip would be a waste of economic income.

• I will still go on the cruise of the ship because the distance of the earthquake occurrence is too far.

• Mt. Pinatubo

• Mt. Makiling

• Mt. Alu

Which correct events should you follow, if you were asked to locate the epicenter of a recent earthquake?

• Determine the difference in the arrival time of S and P waves recorded from each of the seismological stations.

• Use the triangulation method to locate the center.

• Obtain data from three different seismological stations.

• Determine the distance of the epicenter from the station.
