What is a disaster? Is being ill a disaster? Or 75 million people dying in the Black Death? That sounds like a disaster! Find out what kinds of things make disasters happen. Oh, and if disasters are bad - what about mega-disasters? They're a lot worse. Find out here.

Then read the story The Eruption. Who can you trust when a volcano erupts near you? This is one of a series on books on popular non-fiction topics. As with other books in the series, a full colour non-fiction section is followed by a fiction story based upon the topic.

The story appears in two formats: one with simple texts for poor or reluctant readers; the facing pages contain an illustrated "speech bubble" version for those who are just starting to read.
