An earthquake in southeastern Turkey has injured at least seven people and triggered an avalanche.

Istanbul's Kandili observatory says a 5.7 magnitude earthquake struck early Saturday in rural Bingol province.  It was centered in the town of Karliova.

Turkey's Anatolia news agency says the quake apparently triggered an avalanche in neighboring Erzurum province, and is blocking a highway leading to the village of Cat.  At least 20 homes in the area have been damaged.

Provincial officials say recent heavy snowfall is hampering efforts to reach small villages.

Earthquakes are common in Turkey.  In 2003, a magnitude 6.4 quake struck the same region, killing 177 people.
