Assam-Tibet Earthquake (1950)

About

The 1950 Assam-Tibet earthquake was a devastating seismic event that occurred on August 15, 1950. It had a moment magnitude of 8.7, making it one of the strongest earthquakes ever recorded on land and the largest caused by continental collision rather than subduction[1][4]. The epicenter was located in the Mishmi Hills near the India-Tibet border, causing widespread destruction in both regions[1][4]. The earthquake triggered massive landslides and floods, significantly altering the landscape and river courses, particularly that of the Brahmaputra[2][4]. The earthquake resulted in approximately 4,800 casualties, with 1,526 reported in Assam and 3,300 in Tibet[1][4]. It also had profound environmental and economic impacts, disrupting biodiversity and agricultural activities[2]. The event highlighted the seismic risks in the Himalayan region, leading to increased awareness and disaster preparedness efforts[2][4]. The earthquake's effects were felt across multiple countries, including India, China, and parts of Southeast Asia, underscoring its significant regional impact[1][3].
