文摘
- •
We evaluate seismic data and derive a tectonic scenario for the Pamir–Hindu Kush.
- •
Pamir–Hindu Kush host two opposite dipping zones of intermediate depth seismicity.
- •
The Hindu Kush earthquakes are due to the slab-detachment of Indian lithosphere.
- •
The Eurasian Pamir slab is pushed north, stretched and torn apart by cratonic India.
- •
The rheological properties of the lithosphere involved cause this contrasting behavior.
