2018年苏拉威西地震:帕卢的走滑海啸和灾难性液化
The earthquake that defied three textbook rules: strike-slip faults generated a destructive tsunami, the rupture propagated at supershear speed, and liquefaction flows traveled 700 meters on nearly flat ground.
2017年墨西哥城地震:1985年灾难周年纪念日的M7.1
Striking on the exact 32nd anniversary of the 1985 disaster during a national earthquake drill, the 2017 earthquake served as a live audit of Mexico City's three decades of seismic improvements.

2011年基督城地震:6.2级余震如何摧毁市中心
One of the few cases where an aftershock was more devastating than its mainshock, with a M6.2 at just 5 km depth producing 2.2g ground acceleration that obliterated Christchurch's city center.
2011年东北地震:M9.1巨型逆冲断层如何引发日本的三重灾难
The only earthquake in recorded history to trigger a simultaneous earthquake, tsunami, and nuclear disaster, fundamentally changing how nations assess cascading risk.
2010年考蒂恩地震:智利的M8.8巨型逆冲断层和备灾的力量
The clearest modern comparison showing that building codes save lives -- a M8.8 earthquake in Chile killed 525 people while a M7.0 in Haiti (35 days earlier) killed 316,000.
2010年海地地震:7.0级地震如何造成316,000人死亡
The deadliest earthquake relative to magnitude in modern history, demonstrating that building quality and governance -- not earthquake size -- determine whether people live or die.
2008年四川地震:龙门山断层沿线87,000人死亡
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.
2005年克什米尔地震:喜马拉雅边境87,000人死亡
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.
2004年印度洋海啸:21世纪最严重的地震灾难
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.
1999年集集地震:历史上最佳记录的近断层地震
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.
1999年伊兹密特地震:土耳其工业中心的北安那托利亚断层破裂
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.
1995年神户地震:改变日本建筑规范的灾难
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.
1994年北岭地震:美国历史上最昂贵的地震
America's most expensive earthquake, which revealed that thousands of modern welded steel moment-frame buildings had suffered hidden brittle fractures in their connections.
1989年洛马普里埃塔地震:唤醒加州的世界大赛地震
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.
1985年墨西哥城地震:违抗距离的共鸣灾难
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.
1976年唐山地震:20世纪最严重的地震
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.
1970年安卡什地震:南美历史上最严重的地震
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.
1964年大阿拉斯加地震:有记录以来第二大地震(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.
1960年瓦尔迪维亚地震:有记录以来最强大的地震(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.
1950年阿萨姆-西藏地震:有记录以来最大的大陆地震(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.
1948年阿什哈巴特地震:数十年被隐瞒的苏联灾难
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.
1923年关东大地震:火焰摧毁东京的时刻
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.
1906年厄瓜多尔-哥伦比亚地震:定义北安第斯灾害的M8.8巨型逆冲断层
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.
1906年旧金山地震:开启现代地震学的灾难
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.
1868年阿里卡地震:跨越太平洋的海啸的M9.0巨型逆冲断层
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.
1755年里斯本地震:撼动启蒙运动的灾难
The earthquake that launched both seismology as a science and modern emergency management, while simultaneously triggering a philosophical revolution.
1556年陕西地震:人类历史上最严重的地震(830,000人死亡)
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.
