Hamblyn dissects four natural disasters, under the headings of Earth (Lisbon earthquake 1755), Air (European 'weather panic' 1783), Fire (Krakatau 1883) and Water (Hawaii Tsunami 1946). Each is described in narrative, brought to life by accounts and testimonies of survivors, and analysed for lessons about the operations of natural processes and human response strategies.
The book succeeds in putting the reader in amongst the action - for instance, in telling of a freighter obliged to anchor in darkness and wait out the eruption of Krakatoa (there are numerous spellings), with sparks, pumice and hot ash falling a metre thick on the deck, above a hold filled with a cargo of petroleum! His analyses of how the worst effects of these disasters could be mitigated with better planning and sustained funding of sensible policies is clear-headed and balanced, though a contained anger peeps through in the Afterword.
We also learn how the disparate effects of geology are tied together: subduction creating both earthquakes and volcanic eruptions, both of which create tsunamis, whilst a volcano in Iceland was also responsible for the 1783 atmospheric effect. (This was an odd inclusion: a hurricane would seem the obvious illustration of natural forces for 'Air'.) Hamblyn sketches the disaster-driven developments in seismology, vulcanology and oceanography that can now often predict these events and, with proper international action, save thousands of lives.
I wasn't always glued to the page, but this is a solid and illuminating book, exasperated yet optimistic, compelling in its descriptions but devoid of sensationalism.
