How The Indian Plate Collision Makes Afghanistan A 'Shaking' Nation
Earthquake Science: Trapped By Tectonics—How The Indian Plate Collision Makes Afghanistan A 'Shaking' Nation
A 6.3-magnitude quake near Mazar-e Sharif exposed Afghanistan's seismic threat. Experts explained how the collision of the Indian and Eurasian plates causes deadly, frequent tremors.
Afghanistan is part of one of the most tectonically active areas in the world, lying directly on the edge of the Eurasian tectonic plate. This places it within a high-stress transgression zone where it interacts with two other major plates:
The Indian Plate: The Indian plate is relentlessly moving northward and thrusting against the Eurasian plate, a process responsible for the formation of the Himalayas and the numerous quakes experienced across Afghanistan's eastern and northeastern regions.
The Arabian Plate: The northward movement of the Arabian plate to the south also contributes to the immense geological stress on the region.

This constant, multidirectional convergence and shearing along major fault lines like the Chaman Fault results in frequent and often shallow earthquakes, which enhances the effect of their destructive power.
Although seismic vulnerability covers a wide swath of territory, the most severe quakes occur in Eastern and Northeastern Afghanistan, particularly the areas bordering Uzbekistan, Tajikistan, and Pakistan. Even the capital Kabul is very vulnerable, with the highest estimated average annual earthquake damage in the country, at approximately US$17 million.
Moreover, the mountainous topography of the country turns quakes into disastrous landslides, which further worsen the loss of life and property.
Afghanistan has recorded around 100 "damaging" earthquakes since 1900. Some of the worst include:
The list of expert and international agency recommendations for disaster mitigation and resilience is long to reduce the staggering human and economic toll:
A way to ensure earthquake-resistant construction is through the building of new structures according to earthquake-resistant codes, while existing vulnerable buildings, many constructed under traditional non-engineered methods, must be retrofitted to reduce the likelihood of collapse.
Although the government of Afghanistan approved the Afghanistan Building Code, ABC, in 2012, its widespread use and enforcement remain a major challenge.
Monitoring and Mapping: Better monitoring and early warning systems need to be developed for timely warnings. Precise mapping of fault lines using geospatial technology has to be done to inform urban planning and enable the shifting of populations from the most vulnerable zones.
The ever-imminent threat of seismic disaster underlines the immediate necessity for comprehensive disaster preparedness in the country.
