September 10

From 27 September to early November 2020, fighting erupted across Nagorno‑Karabakh and several surrounding Azerbaijani districts. The 44‑day war combined artillery, armored assaults and a new generation of drone warfare. It ended with a Russian‑brokered ceasefire signed on 9 November 2020 and coming into effect on 10 November 2020 (Moscow time), major territorial shifts in Azerbaijan’s favor, the deployment of Russian peacekeepers, and a humanitarian toll that left thousands dead, dozens of towns damaged, and tens of thousands displaced.

A powerful Atlantic hurricane struck Puerto Rico on September 13, 1928 — Saint Philip’s Day — and then carved a path through the Bahamas to make landfall on Florida’s east coast on September 16–17, 1928. The storm wrecked crops, towns, and lives, but its deadliest legacy was the flood from Lake Okeechobee that overwhelmed low-lying settlements and killed thousands. The catastrophe exposed weaknesses in warning systems, racial and economic inequalities in relief, and ultimately drove federal flood-control work that reshaped the lake decades later.

On September 19, 2017, a magnitude 7.1 intraslab earthquake struck near Raboso, Puebla, rocking Mexico City and surrounding states. Coming on the same day as a nationwide drill and the 32nd anniversary of the 1985 disaster, the quake collapsed buildings, killed 369 people, and exposed failures in construction, inspection, and preparedness that reshaped Mexico’s recovery and policy debates.
