A magnitude-6.4 earthquake struck Japan Tuesday morning, after a similar quake rattled the northeastern part of the country Monday evening, CNN reported.
The quake struck at about 8:08 a.m. Tuesday (7:08 p.m. Monday ET), according to the U.S. Geological Survey. It had a depth of about 13 kilometers (8 miles) and was centered about 77 miles east-southeast of Tokyo.
The new earthquake triggered landslides that trapped several people in the city of Iwaki, authorities said.
The quake was centered about 100 miles (164 kilometers) northeast of Tokyo and about 30 miles (50 kilometers) southwest of the crippled Fukushima Daiichi nuclear plant, according to the U.S. Geological Survey.
The landslides in Iwaki buried three houses. Police in Fukushima Prefecture initially reported that four people were trapped. The Iwaki Fire Department later said more than four people were trapped, but the exact number was unclear.
