Oh lord, back on my bullshit. With this Asylum movie that is "what if there was a planet sized quake?" only not really and in a way in which it only matters to a handful of people they can show on screen.
An undersea nuclear bomb is accidentally dropped, setting off an earthquake that will slowly go around the ring of fire from Japan to eventually hitting the US 72 hours later, because of course only what impacts the US matters. Fortunately, against this is one geologist scientist, her assistant, and her smart brother. They fire some orbital lasers to heat up the plate to stop the incoming energy, but that doesn't work. So then they use four local oil rigs to release gas to relieve the pressure, but that doesn't work either as two of the rigs blow up. Fortunately, they can send a missile down one of the rigs to... explode and create a volcano that saves the day??
Geophysics doesn't get a look it, does it?
Also, the scientist's daughter is on a plane that crashes, and her husband is a military man that heads up search and rescue, and his one mission is to go find his daughter (who saves herself). So... they are also in this movie.
This is a mixture of scenes of "a handful of people in small room sets" plus "random stock footage of search and rescue teams" and, of course, "bad cgi". There are also more people just off screen, but they have lines, and it's just unfortunate that they aren't on camera when they talk.
This is Not Good, but as soon as I heard the premise "A tectonic shift deep below the Mariana Trench causes a series of ever escalating earthquakes. If a team of leading seismologists fails to stop the disaster, the events will break apart the Earth, resulting in billions of casualties." I had to check it out.
Ultimately, yes, it's as bad as you think.
