2011 Sendai Earthquake And Tsunami, Tōhoku Region, Pacific Ocean

The rolling blackouts brought on by the crises at the nuclear power plants in Fukushima later had a profound effect on the rail networks around Tokyo starting on 14 March. Major railways began running trains at 10–20 minute intervals (normally 3–5 minutes), operating some lines only at rush hour, and completely shutting down others (notably, the Tokaido Main Line, Yokosuka Line, Sobu Main Line and Chuo-Sobu Line were all stopped for the day). This led to near-paralysis within the capital, with long lines at train stations and many people unable to come to work or get home.
Telecommunications
Cellular and landline phone service suffered major disruptions in the affected area. Internet services, however, have not been affected to a great extent; only a few websites were unreachable. Several Wi-Fi hotspot providers have reacted to the quake by providing free access to their networks.
