An 8.8 magnitude struck 80 miles off of Japan's coast early this morning. It triggered a massive tsunami that devastated the northern coast soon after, giving little time for warning or evacuation. Disaster officials say that at least 32 people have been killed. A tsunami warning has been issued across the Pacific Ocean. The New York Times' Kevin Drew reports on the event from Hong Kong.
