Major quakes hit Japan; tsunami warning for U.S

An 8.9-magnitude earthquake and series of major tsunamis struck Japan on Friday, causing massive damage, triggering evacuations in several countries, and leading to tsunami warnings for Hawaii and the West Coast of the United States.
The quake struck Friday at 2:46 p.m. local time about 230 miles northeast of Tokyo. Aftershocks registered 7.1, 6.2, and 5.9, according to the U.S. Geological Survey's report.

The death toll has been climbing, and Nikkei reported that Miyagi prefecture police said they'd found 200 to 300 bodies of people believed killed by the tsunami. Japanese media said office workers tried in vain to make calls over jammed cell phone networks and were turning to Twitter to communicate with friends and family. Meanwhile an upswell of news and concern was apparent on social networks.
NOAA, the U.S. National Oceanic and Atmospheric Administration, issued a tsunami warning for Hawaii, for parts of Alaska, and for the West Coast of the United States from Oregon to Central California. Washington state and Southern California have a tsunami advisory.
"A tsunami warning means that all coastal residents in the warning area who are near the beach or in low-lying regions should move immediately inland to higher ground and away from all harbors and inlets including those sheltered directly from the sea," NOAA said. "Those feeling the earth shake, seeing unusual wave action, or the water level rising or receding may have only a few minutes before the tsunami arrival and should move immediately. Homes and small buildings are not designed to withstand tsunami impacts. Do not stay in these structures."
According to NOAA's tsunami arrival schedule, the first waves should reach San Francisco at 8:08 a.m. PT. "Tsunami amplitudes [wave heights] are expected to peak two to three hours after initial arrival along the North American coast," NOAA warned.
Television images of Japan on CNN showed waves exceeding 12 feet flowing inland (see video below), causing massive damage and carrying along cars, boats, and small buildings. Hundreds of people were evacuated from Tokyo's Shinjuku Station, purportedly the world's busiest, and train and subway services were halted, according to media reports. Tokyo's main airport was also closed.
In keeping with past efforts to assist in disaster relief, Google has launched Person Finder to help people search for information about others by name or leave information in Japanese.
Twitter captured the events as they happened. The number of tweets coming from Tokyo were topping 1,200 per minute, according to the Tweet-o-Meter, and Hawaii observers chimed in later. "Long lines at gas stations and supermarkets as Hawaii braces for tsunami," tweeted Jaymes Song, an editor for the Associated Press. "Tsunami warning sirens going off in Honolulu," he added
