根据以下内容回答题：Earthquakes may rightly be ranked as one of the most destructive forces

known to man：since reeords began to be written down，it has been estimated that earthquake-related fatalities（死亡）have numbered in the millions，and that earthquake-related destruction has been be-vond calculation．The greater part of such damage and loss of life has been due to falling down of buildings and the effects of rockslides，floods，fire，disease，gigantic sea waves，and other phenomena（现象）resulting from earthquakes，rather than from the quakes themselves． The great majority of all earthquakes occur Off two specific areas，along the coasts of the Pacific Ocean and from the East Indies to the Atlas Mountains．But they may，however，happen anywhere at any time． This element of the unknown has for centuries added greatly to the fear and horror sur-rounding earthquakes，but in recent times there have been indications that earthquake predic-tion may be possible．By analyzing changes in animal behavior，patterns of movements in the earth’S surface．and other unusual phenomena，scientists have shown increasing Success in pre-dicting when and where earthquakes will strike．As a result，a worldwide earthquake-warning network is already in operation and has helped to prepare for the vast destruction that mightotherwise have been totally unexpected． It is．doubtful，that man will ever be able to control earthquakes and do away with the destructiveness altogether。but as how．and why earthquakes happen become better understood，man will become more and more able to deal with their possible destruction before it occurs．

Most destruction caused by earthquakes is the results of the following EXCEPT__________ ．

A.the collapsing of buildings and the fire it causes’

B.the floods and huge sea waves resulting from earthquakes．

C.the disease that often follows earthquakes

D.the panic brought about by earthquakes
