A magnitude 4.8 earthquake rattled a New Zealand city Saturday after it was hit by a powerful temblor earlier this week that resulted in millions of dollars (euros) in damage. Geological agency GNS Science said the aftershock shook the area at 11:30 a.m. local time (2230 GMT Friday) and was centered 30 kilometers (18 miles) southeast of Gisborne at a depth of 30 kilometers (18 miles). There were no reports of injuries or damage from the third magnitude 4 aftershock in a day and a half. Thursday's 6.8-magnitude temblor wrecked an apartment building and two shops in the port city, 50 kilometers (30 miles) from the quake's epicenter. Other damage including caved-in roofs and cracked walls on buildings and gaping holes in roadways.
