Scroll over to asia and locate the java trench. this is where the indian plate and eurasian plate interact. what kind of plate interaction occurs here, that was responsible for the december 26, 2004 tsunami?

This is called the subduction zone. India (i.e. the Indian plate on which India resides) is crashing into the Eurasian plate, and in fact is being pressed down below. This is how the Himalayas were formed, as the Eurasian plate is raised over the Indian plate.

landlessness of ordinary people
