Carbon dating earthquakes

Accelerator mass spectrometry (AMS) is a technique for direct measurement of the concentration of radioisotopes.A radiocarbon measurement can be obtained on a sample of ~0.5 mg of carbon, and measured to 40 years in uncalibrated radiocarbon age in a measurement time of 30–40 minutes on each sample.Watt’s team announced earlier this year that they do indeed connect.Previously scientists believed that they ran parallel to each other.

Geological Survey research team last fall sailed out into San Pablo Bay in search of clues.

This Big One was a major subduction zone earthquake.

A similar-sized quake could occur again at any time....

For decades, scientists have wondered whether these two major Bay Area faults connect beneath San Pablo Bay.

The Rodgers Creek Fault enters the bay from the north; the Hayward Fault enters the bay from the south.

This means that it’s easy for an earthquake rupture to continue from one fault to the next — and that the 118-mile-long rift from Healdsburg to San Jose could deliver a blow greater than the sum of its parts.
