Query: dramatic geoengineering

It doesn't matter where you live on the planet for anywhere man has to battle natural forces to survive. It might be blizzards, Tornadoes, Hurricanes, earthquakes, something will eventually make life difficult. Here John McPhee has selected Flood, volcano, and landslide as the forces of nature and depicted the struggles of Louisiana, Iceland, and LA California.I was mesmorized by the descriptions of red glowing underwater lava flows in Icelandand the precarious cliff edge home-sites in California following massive mud flow disasters.Life seems a little more precarious after reading this but I am also more appreciative of the heroic efforts of so much of humanity thanks to McPhee's writing.
