If you watch a lot of disaster movies, you might sometimes wonder where they got information about the events that they used as the premise of the movies. Films like Volcano, Titanic, Twister and Twisters, Earthquake, The Day After Tomorrow, Deep Impact, and many others are based in some way on science, although some more loosely than others. I can remember watching Jurassic Park, which had a hurricane on radar early in the movie as well as rain storms at several points during the film and wondering why they had the hurricane going in the wrong direction and why raindrops appeared and disappeared from the Jeeps in the middle of the scene of the T-Rex chasing them down the road. I came to the conclusion that they needed a better science advisor. Here is an essay written by Dr. Samantha Montano, a disaster specialist, writing about other movie disasters in Script magazine and how screenwriters can improve their storytelling by getting more science details right. If you are interested in real-life disasters and emergency management I can also recommend her book Disasterology as an excellent commentary on how emergency managers managed other disasters in the past such as Hurricane Katrina.
