Accuracy of Dante's Peak

In the movie Dante's Peak, there were some things that were accurate and some that weren't.

Some of the things that were are:

*They were using seismometers and measuring the acidity in the water to tell if the volcano was going to erupt.

*The volcano had lahars, lava and pyroclastic flows.

*There was a smaller eruption before the big one.

Some of the things that probably wouldn't happen quite that way in real life were:

*The dog probably wouldn't have survived.

*They probably wouldn't have been able to escape from the pyroclastic flows or make it over the lava.

*Everything probably wouldn't have happened so quickly, such as the lake suddenly turning acid when the two teenagers were in it.
