Solution: An earthquake in the area of present-day San Francisco is to be dated by measuring the 14C activity (t1/2 = 5730 yr) of parts of a tree uprooted during the event. The tree parts have an activity of 12

Problem

An earthquake in the area of present-day San Francisco is to be dated by measuring the 14C activity (t1/2 = 5730 yr) of parts of a tree uprooted during the event. The tree parts have an activity of 12.9 d/min·g C, and a living tree has an activity of 15.3 d/min·g C. How long ago did the earthquake occur?
