I love non-fiction and The Great Quake did an excellent job discussing the Good Friday Earthquake that hit Alaska in 1964 and going in depth about what was known about earthquakes and geology at the time. Henry Fountain includes lots of photos and personal testimonies to show just how devastating this quake was and how it changed our understanding of the world. The theory of plate tectonics (a term not even coined yet) was still hotly debated and scientists understanding and research of earthquakes was rudimentary at best. The great quake helped prove the plate tectonics theory, a concept I thought had been around for much longer than it really was. A deeply interesting read although sometimes it did get a little too bogged down in scientific details.
