Uh oh. Trevor Nace on something serious that we didn’t know was happening.
Scientists have found strong evidence that 2018 will see a big uptick in the number of large earthquakes globally. Earth’s rotation, as with many things, is cyclical, slowing down by a few milliseconds per day then speeding up again.
This isn’t going to end well, is it?
Geophysicists are able to measure the rotational speed of Earth extremely precisely, calculating slight variations on the order of milliseconds. Now, scientists believe a slowdown of the Earth’s rotation is the link to an observed cyclical increase in earthquakes.
A link, but not necessarily a cause and effect.
One hypothesis involves Earth’s outer core, a liquid metal layer of the planet that circulates underneath the solid lower mantle. The thought is that the outer core can at times “stick” to the mantle, causing a disruption in its flow. This would alter Earth’s magnetic field and produce a temporary hiccup in Earth’s rotation.
Ipso fact, more earthquakes? We’ll see.
