Read the text and choose the best answer to each question below.

Tsunamis, whose name derives from the Japanese expression for ʻhigh wave in a harbourʼ, are giant sea waves. These waves are quite different from storm surges. They are also referred to by the general public as tidal waves although they have nothing to do with tides. Scientists often refer to them as seismic sea waves, which is far more appropriate because they are often the result of undersea seismic activity.

Tsunamis can be caused when the sea floor suddenly moves, during an underwater earthquake or volcano, and the water above the moving earth is suddenly displaced. This sudden shift of water sets off a series of waves. These waves can travel great distances, at speeds close to 700 kilometres per hour. In the open ocean, tsunami waves are not very high, often no more than one or two metres. It is when they hit the shallow waters near the coast that they increase in height, possibly up to 40 metres.

16th January, 2010
I just arrived in Port-au-Prince, Haiti with the Lend-A-Hand volunteer team and I can't believe my eyes! The earthquake that happened four days ago has destroyed most of the buildings. This disaster has affected three million people. Thousands have lost their lives or have terrible injuries, and even more have lost their homes. Haiti suffers from hurricanes and floods every year, but this is something else! Our team's task is clearing the rubble which is everywhere!

22nd January, 2010
On Tuesday, we pulled a five-year-old boy from the rubble. He was still alive after eleven days! The United Nations has offered a small wage to the people of Haiti for helping to clean up the streets. This helps them to buy food. Conditions are terrible, though. Thousands of people are living in tents with no toilets or running water. The earthquake also caused tsunamis in nearby fishing villages that damaged beaches and even swept homes out to the sea!
