It's not a program (or simulation), it's an animation.

it makes it look as if an earthquake is an explosion underground

[TectonicsObservatory]

Yes, an earthquake, too, is a violent release of energy, and can release more energy than an explosion.

For example, the energy released by the 1994 Northridge earthquake (magnitude 6.7) was 200 times larger than that released by the Hiroshima atomic bomb. The 2004 Sumatra earthquake (M 9.1) released a MILLION times more energy.

And they both cause seismic waves. Oil companies set off underground explosions and then monitor the resulting seismic waves in their search for new sources of oil.

the so call "sudden pop up " a bit too simplifies i must say

[TectonicsObservatory]

@1rootle Yes, "pop up" is a bit too simplified. The time it takes an island to emerge depends on how big it is. The earthquake rupture travels about 3 km/sec. For an island that is 100 km in length, it would take about 30 seconds to emerge.

you know your fucked when you have to look at youtube for information about your Earth Science essay..

[dhidayat2]

It's very educative ...easy to be understand

Steady I Really Like This Video Animation of Earthquake and Tsunami in Sumatra

[Kricardose]

I am very happy to see the vidoe Animation of seismic cycle, showing subduction of oceanic tectonic plate and resulting deformation of upper continental tectonic plate from you, hopefully the others also are happy for You
