A magnitude 6.3 earthquake struck near Mazar i Sharif and Khulm in northern Afghanistan early Monday at a depth of 28 kilometers, the USGS said. An orange PAGER alert warns of significant casualties and potentially widespread damage, with models suggesting hundreds of deaths; the full extent remains unclear. Shaking was felt in Tajikistan, Uzbekistan, and Turkmenistan, and aftershocks followed, the largest at 5.2. “We woke up terrified,” said Rahima, who reported broken windows and damaged plaster. Afghanistan’s disaster agency said several provinces were jolted around 1 a.m.
