What made the 2005 earthquake in northern Pakistan especially destructive?

The 2005 Kashmir earthquake was exceptionally destructive due to a combination of high seismic intensity and structural vulnerabilities. Striking with a magnitude of 7.6, the quake occurred in a region situated on an active fault line created by the northward tectonic drift of the Indian subcontinent.1

The severity of the impact and the high death toll—estimated at 79,000 or more—were significantly exacerbated by poor construction standards in the affected areas, which led to the collapse of over 32,000 buildings.12

The humanitarian crisis was further intensified by the region's challenging geography and the aftermath of the initial shock. Rescue and relief efforts were severely hampered by:

• Frequent aftershocks: These continued to threaten survivors and rescue workers.12
• Landslides and falling rocks: These natural hazards blocked critical infrastructure, including highways and mountain roads, rendering parts of the region inaccessible for several days.12

These factors collectively turned the event into one of the most devastating natural disasters of contemporary times, leaving approximately four million people homeless.1
