Logistics and Impact on Economy The initial shocks destroyed some bridges, roadways, and railways, halting the distribution network of the Tohoku Region including Sendai, a city of one million people. The coastal communities north of Sendai are separated from the population centers along the spine of flat land in the middle of Honshu Island with mountains, and, thus, were rather difficult to reach even before March 11th. Then the destruction of accesses made the logistics an acute problem in the coastal region, where relief materials were needed the most. The quakes and tsunamis also put more than a handful of oil refineries along the Pacific coast out of business, at least initially.
