Today marks the 100th anniversary of San Francisco's great earthquake and fire. After Lisbon's devastating earthquake and fire in 1755, which leveled the city with its 8.7 magnitude in the Richter scale (San Francisco's was "only" 7.8), most Lisboners have a particular interest on the subject. After all, the occurrence of another big quake in Lisbon is not a question of "if": it's merely a question of "when".
