Terremoto de Sichuan 2008: 87,000 muertos a lo largo de la falla de Longmenshan
The earthquake that forced China to confront endemic building code violations after thousands of 'tofu-dreg' school buildings collapsed while adjacent government structures survived, killing over 5,000 children.
Terremoto de Cachemira 2005: 87,000 muertos en la frontera himalaya
The deadliest Himalayan earthquake in modern history, which killed 17,000 students in collapsed schools and demonstrated the extreme difficulty of disaster response in remote mountainous terrain.
Tsunami del Océano Índico 2004: El desastre sísmico más mortal del siglo 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.
Terremoto de Chi-Chi 1999: El terremoto más cercano a la falla mejor registrado de la historia
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.
Terremoto de Izmit 1999: Ruptura de la falla anatoliana del norte en el corazón industrial de Turquía
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.
Terremoto de Kobe 1995: El desastre que transformó los códigos de construcción de Japón
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.
Terremoto de Northridge 1994: El evento sísmico más costoso de 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.
Terremoto de Loma Prieta 1989: El terremoto de la Serie Mundial que despertó a California
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.
Terremoto de la Ciudad de México 1985: El desastre de resonancia que desafió la distancia
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.
Terremoto de Tangshan 1976: El terremoto más mortal del siglo 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.
Terremoto de Áncash 1970: El terremoto más mortal de la historia de América del Sur
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.
Gran terremoto de Alaska 1964: El segundo terremoto más grande jamás 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.
Terremoto de Valdivia 1960: El terremoto más poderoso jamás 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.
Terremoto de Assam-Tíbet 1950: El terremoto continental más grande jamás 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.
Terremoto de Asjabad 1948: La catástrofe soviética que fue ocultada durante décadas
The most concealed earthquake disaster in history, where the Soviet government classified the true death toll of 110,000 as a state secret for 40 years.
Gran terremoto de Kantó 1923: Cuando el fuego destruyó Tokio
The earthquake that proved fire -- not shaking -- is the primary killer in dense urban areas, with 38,000 people perishing in a single fire tornado.
Terremoto de Ecuador-Colombia 1906: El megathrust M8.8 que definió el peligro de los Andes del 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.
Terremoto de San Francisco 1906: El desastre que lanzó la sismología 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.
Terremoto de Arica 1868: El megathrust M9.0 que envió tsunamis a través del Pacífico
One of the most powerful earthquakes before the instrumental era, whose Pacific-wide tsunami carried warships half a kilometer inland and provided crucial calibration data for modern megathrust hazard models.
Terremoto de Lisboa 1755: El desastre que sacudió la Ilustración

Terremoto de Shaanxi 1556: El terremoto más mortal de la historia humana (830,000 muertos)
The deadliest earthquake in human history, killing 830,000 people -- primarily because the population lived in cave dwellings carved into loess cliffs that collapsed en masse during the shaking.
