A shorter day on the planet According to NASA’s estimates, the earthquake cut a day’s duration by around 2.68 microseconds, or less than a second.
Even though 2.68 microseconds may not seem like much, it shows how vulnerable Earth’s systems are to strong geological pressures. Large earthquakes force the planet’s mass to be redistributed, which results in this phenomena.
Massive amounts of water were displaced and a fatal tsunami was created when a large portion of the Earth’s crust under the ocean bottom abruptly slid during the Sumatra earthquake.
The planet’s moment of inertia was also changed by the rearrangement of rock and interior materials.
A local disaster affected the whole world. One of the strongest earthquakes ever recorded occurred in the Sumatra-Andaman region in 2004.
It produced energy equal to almost 23,000 Hiroshima-type atomic bombs and ripped a 1,600-kilometer chunk of the seabed.
Despite the fact that the epicenter was under the Indian Ocean, the impact was so powerful that it changed the velocity of the whole earth.
