Breaking news: Worst landslide in Oso, Washington last year was not a randim event

United States suffered one of its worst landslides in its history last year. In March 2014 at least 40 people lost their lives in Oso, Washington thanks to the landslide.

If you thought that this was the worst landslide in the history of the United States, you are completely wrong.

A new study conducted by the geologists associated with the Washington University has concluded that the last year’s landslide was not a random event.Oso-site-reveals-history-of-landslides

Geologists have established a new method for dating previous landslides applying radiocarbon dating to debris that has been buried. After deploying the latest machines to find out the truth, researchers have concluded that the area had faced a massive slide some 500 years ago.

A researcher who was part of the study says that the soil in the region is actually made up of glacial material and so one of the hypotheses is that the material possibly fell apart in successive large landslides immediately after the ice retreated several thousand years ago.

Nonetheless, the latest study proves this hypothesis completely wrong. Alison Duvali, a coauthor of the report, says that it has now become apparent that ‘many’ of the larger landslides experienced by the area are only several hundred years old and not several thousand years. He goes on to add that the area was also well known for hillslope instability.

While trying to decide the age of the landslides researchers minutely analyzed debris from various trees. Duvali went on to add that large slides can uproot live trees, kill and bury them. When such trees are found in the mass of a landslide, it can be assumed that the landslide ‘killed’ the tree and that can provide the date of the landslide.
