The Japanese earthquake changed our relationship to place, and post-disaster social media changed it again.
“Natural disasters are fundamentally experiences of place: The epicenter was here. It was this many miles from this other place. It affected here and here and here. Place is understood through position and relationship, through contact and distance.
Geography determines terrestrial points of contact. These change, but usually at a rate barely perceptible to the human eye. Politics and language anchor societal points of contact, through alliance, ideological similarity, and shared knowledge. These change more quickly than continents, but stay stable long enough to fill history textbooks. Communication technologies scaffold personal points of contact. These change quickly indeed.”
