Carbon dating earthquakes

A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.

How do scientists know how old an object or human remains are?

Primary evidence includes clues that are created by the movement on the fault during the earthquake such as fault scarps, offset or folded layers of sediment and soil, and parts of the landscape that have been tilted, uplifted, down-dropped, or torn apart.

The fissures were subsequently filled by the next layer of sediment.

Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.

It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.

Finding these paleoearthquakes requires going to the right place.

First, scientists study the landscape to find places where the faults are active.
