Earthquake in Japan Shortens Earth’s Days



You just read about how to survive an earthquake in the previous article, but did you know that Earthquake can shorten earth day?

The earth rotates on a north-south axis; the planet is balanced as it rotates by instances such as ocean currents and when an earthquake of such magnitude erupts, the natural ‘wobble’ is then thrown off balance.

As a result of the earthquake in Japan last Friday, the earth has experienced a shift in its falter by approximately 6.7 inches; thus, our earth days have been shortened. Scientists are approximating the shortening of days to be somewhere around 1.8 microseconds. While this may not seem like much, there have been prior earthquake eruptions that have also added to the shortening of days.

Collectively, these circumstances have a greater toll on the earth than what is physically visible to those not experiencing it.

Given the extent of the change that earth has experience from the earthquake in Japan, the outcomes have been labeled as “good”, since they will now allow for scientists to accurately measure the deviation, rather than placing a typical calculation on the measurement.

From this point forward, it is a matter of determining what this means for the rest of the earth. The data that has been collected thus far, is being evaluated to determine whether or not there were any variations in this 9.0 magnitude earthquake that were not present in other monstrous quakes that have hit other parts of the world in the past.

Recommended Watch



The collection of data from the Japan earthquake is expected to span over a few months, as scientist want to ensure they take every aspect of the quake into consideration. The instruments currently being utilized span over an array of areas and details that will help scientist uncover the true magnitude of the earthquake in Japan that took place last Friday.
