C always are huge and destructive d can be predicted

C. Always are huge and destructive.
D. Can be predicted with some accuracy seconds to hours before the waves strike in most cases,
allowing quick warnings to save many lives.
E. Can be predicted accurately months in advance, allowing evacuations.
Because tsunamis are triggered by earthquakes, among other things, and we cannot predict earthquakes
accurately, we cannot make months-in-advance predictions of tsunamis. The p-waves from the
earthquakes that cause the most common tsunamis move more rapidly than the tsunamis do, allowing
timely warnings; however, because the tsunamis get where they are going in hours or less typically, not
much time is available. Water does go out before rushing in along some coasts, but comes in before
going out along other coasts, waves have “up” and “down” parts, and some coasts get an “up” first while
other coasts get a “down” first. Little earthquakes make little tsunamis; big earthquakes make big
tsunamis.
