Today, we explore the layered geography of San Diego, where a fracture in the Earth stands capable of producing a magnitude 6.9 earthquake that could fundamentally rewrite the city in under 18 seconds. From the vulnerable artificial land of Mission Bay to the glass-covered streets of downtown and the fragile coastal bluffs of La Jolla, this exploration uncovers a full, scientifically modeled, 24-hour timeline of exactly what happens if the Rose Canyon fault breaks on a normal Tuesday morning. Whether looking at the physics of the shake, the threat of post-earthquake fires, these structural realities are still beneath our feet if we know what to anticipate. In This Video: 🔹 The hidden fracture that seismologists consider one of Southern California's most dangerous urban faults 🔹 How seismic waves travel and the crucial 8-second window offered by California's ShakeAlert system 🔹 The impact of harmonic resonance on downtown skyscrapers and why Broadway becomes instantly impassable 🔹 The story behind the liquefaction of Mission Bay and the physics of dredged sediment fill 🔹 How a major rupture isolates communities like Coronado and cuts critical utility main lines 🔹 Why understanding these prehistoric seismic indicators matters for planning and survival in a growing city ---------------------------------------------------------------- Copyright & Fair Use Full image/video credits here: [https://docs.google.com/document/d/1ASpzvyetvo4
