An earthquake measuring upper-5 on the Japanese seismic intensity scale of 7 shook Aomori Prefecture and other parts of the north on Tuesday afternoon, hours after another temblor triggered a small tsunami. The second instance did not result in a tsunami alert. The quake struck at 1:46 p.m. The Japan Meteorological Agency described it as magnitude 5.7, with an epicenter around 50 km off the coast of Iwate Prefecture and 50 km deep. One of the hardest-hit districts was the town of Hashikami, where upper-5 was recorded.
