A 7.3 magnitude tremor struck the island of Kyushu early Saturday morning, killing at least 42 people, injuring about 1,000 more and causing widespread damage. Japan wasn't alone. Ecuador over the weekend was hit with its biggest quake in decades, which killed at least 272 people and injured over 2,000. Nikkei -3.4%.
