8.9 is one of the largest earthquakes every recorded. Tokyo is still having 5-7 mag earthquakes as I write this at midnight, more than 9 hours after the first quake. I wanted to give credit to viber today, a free iphone app that lets you make voice calls over the data network.
Since everyone was trying to make calls today the network was flooded and NOBODY could make a voice call, at least I didn't see one person able to. Although, my viber app did! I was able to call my family back in the US through viber and other friends in Japan. It was like an emergency special phone. I highly recommend everyone to get it, in case these types of diasters happen again.
