The quake generated a tsunami of at least 23 feet that swept boats, cars, buildings and tons of debris miles inland in Japan. Smaller swells struck other Pacific Rim countries and even the United States, causing serious but far less extensive damage.According to local police counts nationwide, the death toll stood at 1,886 with 2,369 missing as of Monday night, the Kyodo news service reported. That toll is expected to climb sharply to around 10,000, according to estimate from Japanese officials, as emergency workers reach the hardest hit areas.
