Paul Beckwith on the recent storms

Recent Storms Moved Giant Rocks Weighing Up to 620 tons: Part 1 of 4

8 March, 2018

It turns out that “Storms of our Grandchildren” are already here today.  In fact these storms are already reconfiguring our coastlines. If you live in a coastal city you are likely aware that rising sea levels, large and intense storms with their associated storm surges, combined with king tides and perhaps even land subsidence are encroaching and damaging houses, streets, bridges, high-rises; in fact all infrastructure is threatened.

The energy in recent storms is enormous, and has moved enormous boulders weighing as much as 620 tons in Ireland.

The tonne (/tĘŚn/ ( listen)) (non-preferred SI derived unit; SI symbol: t), commonly referred to as the metric ton in the United States, is a non-SI metric unit of mass equal to 1,000 kilograms; or one megagram (Mg); it is equivalent to approximately 2,204.6 pounds, 1.102 short tons (US) or 0.984 long tons (imperial).

Thus 620 t = 683 US tons.
