ADAPAZARI, Turkey (AP) _ Two moderate earthquakes rocked this town in western Turkey on Sunday, causing panic among tens of thousands of people living in tents since the deadly earthquake this summer that destroyed their houses.

Seven people were hospitalized for shock, the Anatolia news agency said. One of them, a 55-year-old woman, later died of a heart attack at the hospital.

The tremors _ with preliminary magnitudes of 5.0 and 4.3 _ struck in one of the areas hit most severely by the Aug. 17 quake, which had a magnitude of 7.4 and left more than 17,000 people dead.

There were no reports of damage. But authorities warned citizens not to enter houses damaged in the previous quake.

Istanbul's Kandilli observatory said the tremors were aftershocks of the August quake. Many aftershocks have struck the area since then.
