I thought tsunami's were caused by movement of the tectonic plates...
You would be correct with respect to the Indonesian Tsunami. Very much correct.
There are othe natural causes of a Tsunami:
Such as a massive volcano eruption causing millions of tons of the volcano peripheral to break apart and suddenly crash into the ocean, as well as another known cause of a Tsunami created by massive glacial ice crashing into a bay of water.
But yes, The Indonesian Tsunami causation was exactly as you described; tectonic plate shifting.
