The magnitude 8.0 quake was followed
by 29 smaller tremors throughout the region and spawned a series of four
powerful waves that wiped out several villages, killing at least 89 people.
Though nowhere near as severe as the December 2004 tsunami that left over
200,000 people dead in the Indian Ocean, this latest quake-generated behemoth
wave is a reminder of the volatility of the ocean floor in this part of the
world.
It also made me wonder, if we know
that this part of the world is so prone to tectonic activity and the
devastating waves it creates, can we do anything to predict it? It turns out
that the answer is a qualified "yes". Currently, scientists track
tsunamis with surface instruments such as devices on buoys that record small
changes in sea-surface elevation. However, this method is spotty, as it
requires that a reader be placed in the correct location, which could
theoretically be anywhere. Also, this type of detection provides very little
advance warning because it detects the wave as it passes.
