The largest earthquake ever recorded in the area shook Haiti on Tuesday, collapsing a hospital where people screamed for help. Other buildings also were damaged and scientists said they expected "substantial damage and casualties."

With communications disrupted there were no reports of deaths or injuries soon after the quake, as powerful aftershocks shook the country.

The earthquake had a preliminary magnitude of 7.0 and was centered about 10 miles west of the capital of Port-au-Prince, the U.S. Geological Survey said. It had a depth of 5 miles. It was the largest quake recorded in the area, said USGS analyst Dale Grant, and the last major one since a magnitude-6.7 temblor in 1984.
