Prishtina, Kosova (9098.6 km N of epicenter) [Map] / Light shaking (MMI IV) : I was studying for my exam at nearly 04;00 o clock. It was very quiet when I suddently felt or maybe heard a strange noise coming from outside or better saying coming from the uder ground. I never felt an earthquake before. At the same day, after 18 hours i felt another earthquake, stronger han the first one. Strange!
