B The largest earthquake
(magnitude 里氏9.5) of the 20th century happened on May 22, 1960 off the coast of
South Central Chile. It generated (生成) one of the most
destructive Pacific-wide tsunamis (海啸). Near the generating area, both the
earthquake and the tsunami were very much destructive, particularly in the
coastal area from Concepcion to the south end of Isla Chiloe. The largest
tsunami damage occurred at Isla Chiloe—the coastal area closest to the
epicenter(震中). Huge tsunami waves measuring as high as 25 meters arrived within
10 to 15 minutes after the earthquake, killing at least two hundred people,
sinking all the boats, and flooding half a kilometer inland.
There was large damage and loss of life at Concepcion, Chile’s top industrial
city. Near the city of Valdivia, the earthquake and following aftershocks
generated landslides which killed 18 people. At the port city of Valparaiso, a
city of 200,000, many buildings collapsed. A total of 130,000 houses were
destroyed—one in every three in the earthquake zone and nearly 2,000,000 people
were left homeless. Total damage losses, including to
agriculture and to industry, were estimated (估计) to be over a half billion
dollars. The total number of deaths related with both the tsunami and the
earthquake was never found accurately for the region. Estimates of deaths
reached between 490 to 5,7002 with no distinction(差别) as to how many deaths were
caused by the earthquake and how many were caused by the tsunami. However, it is
believed that most of the deaths in Chile were caused by the tsunami. What is the total number of deaths in the earthquake
A.2,000,000
B.Between 490 to 5,7002
C.200,000
D.It was hard to know
