Gempa Bumi Kashmir 2005: 87.000 Mati di Perbatasan 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 Samudra Hindia 2004: Bencana Gempa Bumi Paling Mematikan Abad ke-21
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.
Gempa Bumi Chi-Chi 1999: Gempa Dekat-Sesar Paling Terkalibrasi dalam Sejarah
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.
Gempa Bumi Izmit 1999: Ruptur Sesar Anatoli Utara di Jantung Industri Turki
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.
Gempa Bumi Kobe 1995: Bencana yang Mengubah Kode Bangunan Jepang
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.
Gempa Bumi Northridge 1994: Peristiwa Seismik Paling Mahal Amerika
America's most expensive earthquake, which revealed that thousands of modern welded steel moment-frame buildings had suffered hidden brittle fractures in their connections.
Gempa Bumi Loma Prieta 1989: Gempa World Series yang Membangunkan 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.
Gempa Bumi Mexico City 1985: Bencana Resonansi yang Menentang Jarak
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.
Gempa Bumi Tangshan 1976: Gempa Paling Mematikan Abad ke-20
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.
Gempa Bumi Ancash 1970: Gempa Paling Mematikan dalam Sejarah Amerika Selatan
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.
Gempa Bumi Besar Alaska 1964: Gempa Terbesar Kedua yang Pernah Dicatat (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.
Gempa Bumi Valdivia 1960: Gempa Paling Kuat yang Pernah Dicatat (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.
Gempa Bumi Assam-Tibet 1950: Gempa Benua Terbesar yang Pernah Dicatat (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.
Gempa Bumi Ashgabat 1948: Bencana Soviet yang Tersembunyi Selama Puluhan Tahun
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.

Gempa Bumi Ekuador-Kolombia 1906: Megathrust M8.8 yang Mendefinisikan Bahaya Andes Utara
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.
Gempa Bumi San Francisco 1906: Bencana yang Meluncurkan Seismologi Modern
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.
