In order to provide an early warning system, which of the following is LEAST helpful in trying to predict a tsunami?
A) world-wide seismic networks that broadcast warnings based on an earthquake's potential for generating a tsunami
B) deploying warning buoys to detect small changes in sea level
C) monitoring earthquakes on land
D) considering the tectonic setting and type of plate boundary that is nearby
Early Warning System
A system designed to detect and provide advance notice of potential dangers, such as natural disasters, to minimize their impacts.
Seismic Networks
Arrays of seismographs or seismic stations spread over an area to monitor and record earth movements and earthquakes.
Warning Buoys
Floating devices placed in bodies of water to alert mariners of potential hazards, changes in weather conditions, or to mark safe navigation channels.

Final Answer :
C
Explanation :
Monitoring earthquakes on land is the least helpful in predicting a tsunami because tsunamis are primarily caused by underwater earthquakes, volcanic eruptions, or landslides. While land earthquakes can potentially trigger tsunamis if they lead to underwater disturbances, the direct monitoring of oceanic activities and conditions (such as with buoys and seismic networks focused on the ocean) provides more immediate and relevant data for tsunami prediction.
