Scientifically Accurate:
1. Magma movement causing shaking/movement not just Plate Tectonics
2. Having more then one explosion with composite volcanoes
3. Pyroclastic flow
Inaccurate:
1. The acid in the water just showing up instantly
2. Driving through the lava and hot ash would have popped the tired, they wouldn't have made it through there without at least melting the tire, or getting a flat.
3. Chances are the dog wouldn't have made it to where they did the drive by sort of deal to pick him up, he ultimately would have burned his paws waaaaaaaayyyyyy before then walking on all of that stuff..
