Parkfield Earthquake looks to be on schedule

The only formally endorsed prediction of an earthquake in the Unites States appears to be holding up well. The magnitude 5.6 Parkfield Earthquake, expected to strike a section of the San Andreas in sparsely populated central California in January 1988, give or take 5 years, would appear to be on schedule despite a jolt to the Parkfield area from the nearby Coalinga earthquake.
