A magnitude-5.7 earthquake struck off the southeast coast of Taiwan Friday, the Central Weather Bureau's Seismology Center said. There were no immediate reports of property damage or human casualties. The earthquake struck at 9: 07 a.m., with the epicenter located 131.7 kilometers southeast of the bureau's seismology monitoring station in the eastern city of Hualien at a depth of 31.1 km beneath the seabed, seismologists said. The strongest intensity on land was recorded in Changpin township in the neighboring Taitung County, where the quake registered at Intensity 3. Intensity in other parts of Taiwan ranged between 2 and 1. Taiwan is often hit by earthquakes as it lies near the the junction of two tectonic plates. A 7.3-magnitude quake killed around 2,400 people in Taiwan Sept. 21, 1999.
