How often do seismic records register earthquakes in the Pamirs?

Seismic records in the Pamirs register approximately 2,500 earthquakes each year, with a major seismic event occurring about every 15 years. The region, along with the neighboring Hindu Kush, is part of the most seismically active intermediate-depth earthquake zone in the world, a result of the ongoing collision between the Indian and Eurasian continental plates. These seismic activities can occasionally trigger landslides, which have historically dammed rivers to create lakes, such as Lake Sarez.123
