From the asteroid of Armageddon to the climate change disaster of The Day After Tomorrow we move underneath the earth for another end of the world scenario, this time predicated by a super-massive volcano lying underneath Los Angeles. Volcano is about as preoccupied with scientific accuracy as most effects-heavy natural disaster blockbusters - i.e. hardly at all - but we shouldn't let that get in the way of a touch of over the top destruction. If you want to quibble about the accuracy, though, you can start with the San Andreas fault - as a "strike slip" it means that it slides past the nearest plate, whereas for a volcano to form the two need to slide under one another in order for the magma to move to the surface, a process known as subduction. While much of that might sound like boring and irrelevant, it's perhaps infinitely more interesting than Volcano itself, which turned out to be considerably less exciting than watching a lava lamp for nearly two hours.
