Volcano Adventure

Volcano Adventure is a 1956 children's book by the Canadian-born American author Willard Price featuring his "Adventure" series characters, Hal and Roger Hunt.

It depicts a journey to several of the world's most dangerous volcanoes.

The story involves the brothers meeting a volcanologist and deals with volcanology, perhaps one of the more scientific of Price's novels.

[1] He wrote: "Hal and Roger Hunt have a fantastic never-say-die attitude, and show great problem-solving skills as they save the lives of people from deadly volcanic disasters.

It's very well researched too, and most of the events are based upon real-life volcanic disasters.
