O Tsunami do Oceano Índico de 2004: O Desastre de Terremoto Mais Mortal do Século XXI
The deadliest tsunami in modern history, killing 227,898 people across 14 countries, whose aftermath created the Indian Ocean Tsunami Warning System and transformed global disaster preparedness.
O Terremoto Chi-Chi de Taiwan de 1999: O Terremoto Próximo à Falha Mais Bem Registrado da História
The best-instrumentally-recorded large earthquake in history, with 441 strong-motion stations capturing near-fault data that fundamentally changed how engineers design buildings close to active faults.
O Terremoto de Izmit de 1999: Ruptura da Falha Anatoliana do Norte no Coração Industrial da Turquia
The latest in a remarkable 60-year westward migration of M7+ earthquakes along the North Anatolian Fault, with stress calculations now pointing directly at Istanbul for the next major rupture.
O Terremoto de Kobe de 1995: O Desastre Que Transformou os Códigos de Construção do Japão
The earthquake that exposed fatal weaknesses in Japan's pre-1981 building stock, leading to the most sweeping seismic engineering reforms in history and proving that building codes save lives.
O Terremoto de Northridge de 1994: O Evento Sísmico Mais Caro da América
America's most expensive earthquake, which revealed that thousands of modern welded steel moment-frame buildings had suffered hidden brittle fractures in their connections.
O Terremoto de Loma Prieta de 1989: O Terremoto da Série Mundial Que Acordou a Califórnia
America's first live-televised earthquake, broadcast to 62 million World Series viewers, whose Cypress Freeway collapse catalyzed California's seismic retrofit program for elevated highways.
O Terremoto da Cidade do México de 1985: O Desastre de Ressonância Que Desafiou a Distância
The definitive case study in site amplification and structural resonance, where lake-bed sediments selectively amplified 2-second seismic waves that destroyed mid-rise buildings 350 km from the epicenter.
O Terremoto de Tangshan de 1976: O Terremoto Mais Mortal do Século XX
The deadliest earthquake of the 20th century, which destroyed 93% of an industrial city in seconds and exposed the limitations of earthquake prediction despite China's success at Haicheng one year earlier.
O Terremoto de Ancash de 1970: O Terremoto Mais Mortal da História da América do Sul
The deadliest earthquake in South American history, where a 50-million-cubic-meter avalanche from Mount Huascaran traveled at 300 km/h to bury the town of Yungay, killing 92% of its population.
O Grande Terremoto do Alasca de 1964: O Segundo Maior Terremoto Jamais Registrado (M9.2)
The second-largest earthquake ever recorded and the event whose geological investigation by George Plafker provided critical field evidence for the then-controversial theory of plate tectonics.
O Terremoto de Valdivia de 1960: O Terremoto Mais Poderoso Jamais Registrado (M9.5)
The most powerful earthquake ever instrumentally recorded, releasing energy equivalent to 25% of all global seismic energy over a century and generating a tsunami that crossed the entire Pacific Ocean.
O Terremoto de Assam-Tibete de 1950: O Maior Terremoto Continental Jamais Registrado (M8.6)
The largest earthquake ever recorded in a purely continental setting, demonstrating that the Himalayan collision zone can produce M8.6+ earthquakes far from any ocean.
O Terremoto de Ashgabat de 1948: A Catástrofe Soviética Que Ficou Oculta por Décadas

O Terremoto Equador-Colômbia de 1906: O Megathrust M8.8 Que Definiu o Perigo dos Andes do Norte
The earthquake that established the segmented rupture model for subduction zones, as its 500 km rupture was partially re-ruptured in three subsequent earthquakes -- a textbook case of megathrust supercycles.
O Terremoto de San Francisco de 1906: O Desastre Que Lançou a Sismologia Moderna
The earthquake that founded modern seismology -- H.F. Reid's analysis of the 1906 rupture produced the elastic rebound theory, the fundamental explanation of why earthquakes occur.
