A powerful 8.9 magnitude earthquake struck the coast of Japan on Friday, causing widespread power outages, fires and a severe tsunami that was reported to be up to 10 meters high in places. It was the seventh most powerful earthquake in recorded history.
The reaction on Twitter, quickly becoming the go-to service in emergencies, was immediate and intense. Less than an hour after the quake, with the country's phone system knocked out, the number of tweets coming from Tokyo were topping 1,200 per minute, according to Tweet-o-Meter.
