Our transcription: The fact that geologists and many public officials have known for some time which areas are most vulnerable to earthquakes is of little comfort to those whose lives have been devastated by this disaster.
But as the focus shifts from the horror of Loma Prieta to the inevitability of future quakes, the race to increase our knowledge and somehow prepare for this seismic giants intensifies.
The approach that generally attracts the most attention, and yet continues to be the most elusive, is "earthquake prediction."
Scientists are studying everything from magnetic fields to groundwater levels and deformation of the Earth's crust in an effort to come up with a formula that can accurately predict earthquakes.
While some promising work has been done, a definite earthquake prediction technique has yet to be developed.
