Continuity mistake: When Travis gives Tai the invitation to the Valley party when she, Cher and Dionne are walking, the notebook flips over in Tai's hand between the wideshot and last close-up - note its flap.
Continuity mistake: Near the end of the movie, when Josh and Cher talk on the stairs, the shot changes to a close-up and they have moved from their previous positions. They are slightly closer together, and their legs are positioned differently.
Continuity mistake: When Murray parks the car in front of the Valley party house, the car blocks the stairs, but next shot when they get out of the car it's much farther up.
Continuity mistake: Amber's hair length changes throughout the movie. For example, when they are in gym class her hair is long but in the scene where Cher and Christian first meet her hair is short. This happens throughout the whole movie.

Continuity mistake: After coming home from the party, Josh and Cher are talking while watching Ren and Stimpy. Cher's combing her hair and picks up a clip beside her, to her left. Before she has a chance to put that clip in her hair, when she picks up the phone that clip is already in her hair.

Continuity mistake: At the valley party, after Travis tries to see how Tai is while she's laid out on the counter, Cher pushes him all the way out of the kitchen so that his entire body is in the doorframe.

Continuity mistake: When Cher's driving instructor tells her she failed her test, the instructor is sitting next to her, then we see a brief shot of Cher crying, then we see the instructor out of the car and at the front of it. The camera wasn't off him long enough for him to get out of the car and walk that far, and we didn't hear a door opening or closing.
Answer: Malibu is a hazardous place to live. It's constantly threatened by wildfires, which burn out the underbrush. Then when it rains, there's nothing on the ground to keep the mud from sliding down the hills, so mudslides are a problem, too.
