The Indian Ocean earthquake and tsunami showed humans the power of the nature. Although we have islands and submerged reefs as natural barriers to tsunamis, we need to be prepared for potential dangers. Sometimes the earthquake in the deep ocean does not cause any loss as the epicenter is far from the land, but the tsunami generated by the displacement of the water can cause huge damage. Tsunami waves can move at 800 km per hour in the ocean and can be several meters high. The main argument in the paragraph above is
A. Earthquakes and tsunamis warn people to pay attention to the ocean
B. Earthquakes and tsunamis in the Indian Ocean warn us to focus more on oceanography
C. Tsunamis generated by earthquakes can cause huge damages
D. Natural disaster is cruel
