Perfect Storms

September 1, 1923. A 7.9 magnitude earthquake strikes off the coast of Japan. The shockwaves devastate Tokyo, Yokohama and surrounding areas. In the rubble, thousands of fires break out and are quickly whipped into a firestorm, aided by strong winds from a typhoon lurking offshore. In a downtown open space where earthquake survivors had taken refuge, the firestorm triggers an extremely rare "dragon twist" - a tornado filled with burning debris - which kills an astounding 35,000-40,000 people in just 15 minutes. Known as the Great Kanto Earthquake, this disaster remains the deadliest in Japanese history, killing between 120,000 to 140,000 people. In the political and social chaos that follows, Japan is set on a new militaristic path towards the Second World War.

In 1755, a powerful earthquake shakes the city of Lisbon for an astonishing 5-6 minutes. Survivors climb out of the rubble and flee to the riverbank only to be engulfed by a massive tsunami. Then the fires start. The city burns for eight days. Tens of thousands die and Portugal is crippled as an imperial power; but out of the rubble new ideas and scientific study take route. Helping to usher in a new age, The Enlightenment.
