I'm still not used to living in earthquake territory, so it took me about two seconds to realize it was a tremor! By the time I had hopped out of bed and run to the nearest doorframe, it was over.
But earthquakes are no joke here. In June 2001, Arequipa experienced a 6.9 on the Richter scale. Twenty one people were killed and 47 homes collapsed. In 1600, an earthquake decimated the city only sixty years after its founding. Other major earthquakes occurred in 1687, 1868, 1958 and 1960.
I need to work on my reaction time.
