Bibliophilic bishop Richard de Bury lamented the burning of the Library of Alexandria. “Who would not shudder at such a hapless holocaust, where ink is offered up instead of blood,” he wrote in 1344, “where the devouring flames consumed so many thousands of innocents?”

When Albert Einstein visited Beno Gutenberg, a seismologist at Caltech, in 1933, the two strolled around the Pasadena campus while Gutenberg explained earthquake science. Suddenly their wives arrived to inform them there had been a massive earthquake. “We had become so involved in seismology,” recalled Gutenberg later, “that we hadn’t noticed.”

“Thank the good God we have all got through and the only family that did not eat human flesh,” wrote fourteen-year-old Virginia Reed, a surviving Donner Party member, in an 1847 letter. “Don’t let this letter dishearten anybody and never take no cutoffs and hurry along as fast as you can.” Reed reported being “pleased with California, particularly with the climate.” 

The destruction of Sodom and Gomorrah may have been caused by an earthquake that occurred through the Great Rift Valley around 1900 bc. The “brimstone and fire” described in the Bible would have been due to petroleum and gases present in the area igniting the cities.

Hatches of Rocky Mountain locusts (Melanoplus spretus) in 1874 and 1875 brought swarms up to 1,800 miles long and 110 miles wide across the Great Plains. Numbers were estimated in the trillions. Farmers risked starvation. The swarm is believed to have been the largest mass of living insects ever witnessed by modern man—but within thirty years the species disappeared. “I can’t believe M. spretus is extinct,” said ecologist Dan Otte in 2014. “But where to look for it?”

A 1959 Chicago Daily Tribune article about Robert Frost, who had recently proclaimed his confidence in humanity’s resilience in the face of missile threats, ran with the headline human race bomb proof, poet believes.
