1.   And a fish in a high school biology lab in California would flip on its side before some quakes occurred, according to published reports.

2.   But a new study in the journal Science by researchers at the California Institute of Technology and Stanford suggests that a quake could occur much sooner.

3.   David Rohr, chairman of the geology department at the university, said he was at home when the quake occurred.

4.   Ellsworth, however, noted that a shallow quake can someday occur in Seattle.

5.   Holmes has found that the probability of death from falling rubble has much to do with the time of day a quake occurs.

6.   If a similar-sized quake had occurred at a more shallow depth, closer to populated areas, they said, damage could have been much worse.

7.   If the quake had occurred just two hours later, the offices and clinics below would have been filled with patients and employees.

8.   Most quakes there occur along faults where the ground moves laterally, and severe damage is fairly localized.

9.   That makes it hard to tell where strain is building or where the next quake will occur.

10.   The Itami railroad station had buckled under the weight of two trains that had been parked on the second floor of the station when the quake occurred.
