Carbon dating earthquakes

A new way of dating skeletons by using mutations in DNA associated with geography will avoid the difficulties and inaccuracies sometimes associated with existing dating methods. Gihon Spring was crucial to the survival of its inhabitants, and archaeologists had uncovered the remains of a massive stone tower built to guard this vital water supply. Using the largest set of radiocarbon dates ever obtained from a single Maya site, a team of archaeologists have developed a high-precision chronology that sheds new light on patterns leading up to ...

Legend states that after the Greek army defeated the invading Persian forces near the city of Marathon in 490 B. E., the courier Pheidippides ran to Athens to report the victory and then immediately ...

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.

Arctic sea-ice has decreased rapidly during the last decades in concert with substantial global surface warming.

The use of lidar (See Down in the Trenches and Up in the Air) in geological investigations has made it much easier to map active faults.

Lidar can cover a lot more ground than a few geologists hiking around looking for evidence of past earthquakes, and its ability to “see through” the vegetation also allows coverage in areas where it may be difficult or impossible for scientists to access.

Therefore, the more information that can be gathered about the past, the better idea we’ll have about what is likely to happen in the future.

This is important because we need to be able to design bridges and big buildings to withstand future large earthquakes, and to plan so we can be resilient in the days and years after the big earthquakes occur.

This type of research is called paleoseismology (“paleo&Close Curly Double Quote; means old, and “seismology&Close Curly Double Quote; is the study of earthquakes, so paleoseismology is the study old earthquakes).
