Cyclists (triathletes actually, but they were riding bicycles) on a ride in a rocky canyon dodged huge boulders crashing all around them during the Christchurch earthquake. More here: Cyclists dodge rocky death!!!
My completely ludicrous earthquake preparedness plan involves biking and, where necessary, walking, running and bushwhacking back home over the Santa Cruz Mountains, with a detour through Morgan Hill, Gilroy and Watsonville if necessary. My co-workers make fun of the food stash in my office, but biking over earthquake destroyed roads takes a lot of energy. My dad knows something about that – he was among the very first responders to arrive after the 1995 Kobe quake when he and his team hauled relief supplies in by bike.
Fallback communication involves relaying messages through family in Colorado and Texas. We live about 200 yards from Hank. Hank’s a Santa Cruz County Amateur Radio Emergency Relay Service operator with a huge army surplus diesel generator that can provide power for his entire neighborhood for a couple of months, and he tests it monthly.
