Aftershocks plagued a rural area of coastal central Japan on Monday, a day after a powerful earthquake killed at least one person as it toppled aging farmhouses and temples, set off landslides and caused a small tsunami. Some 170 people were injured. Sunday's magnitude-6.9 quake struck at 9:42 a.m. (0042 GMT) off the Noto Peninsula on the Sea of Japan coast. The Meteorological Agency issued a tsunami warning urging an evacuation, but the alert was lifted after a 10-centimeter (6-inch) wave hit the shore, causing no damage. The temblor was a shock to the region, which had not seen a major quake since 1933.
