1999 इज़मित भूकंप: तुर्की के औद्योगिक दिल में उत्तर अनातोलियन सदन टूटना
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 कोबे भूकंप: आपदा जिसने जापान के निर्माण कोड को बदल दिया
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 नॉर्थरिज भूकंप: अमेरिका की सबसे महंगी भूकंपीय घटना
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 लोमा प्रिएटा भूकंप: वर्ल्ड सीरीज भूकंप जिसने कैलिफोर्निया को जगाया
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 मेक्सिको सिटी भूकंप: अनुनाद आपदा जिसने दूरी को चुनौती दी
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 तांगशान भूकंप: 20 वीं सदी का सबसे घातक भूकंप
