This creates an error in the "raw" age of about 2 percent.

Since nearly all applications where the precise age is needed require calibration, this difference is removed in the calibration process].

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.

About one carbon nucleus in a trillion contains two extra neutrons, giving a mass of 14.

This carbon-14 is radioactive and decays with a half-life of 5730 years.

This Big One was a major subduction zone earthquake.

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

He also knew that such a large quake would generate tsunamis. So he looked to Japan for evidence, because Japan has some of the oldest written records of any country along the Pacific Rim.
