TOKYO (AP) _ A moderate earthquake hit Tokyo and neighboring areas Friday, but there were no immediate reports of damage or injuries.
The earthquake, with a preliminary magnitude of 4.8, was centered about 35 miles underground in southern Chiba Prefecture, 45 miles southeast of Tokyo, the Meteorological Agency said.
The agency said there was no danger of tsunami, undersea waves triggered by volcanic activity or earthquakes, arising from the temblor, which struck at 10:58 a.m.
The quake also was felt in seven other prefectures, including the Tokyo metropolitan area, and caused buildings to sway in central Tokyo.
A magnitude-4 earthquake can shake houses and buildings and cause hanging objects like lamps to swing. A magnitude-5 quake is strong enough to crack walls and break windows.
Earthquake-prone Japan sits atop four tectonic plates, slabs of land that move over the earth’s surface.
