Koryak Okrug (Russian: Коря́кский о́круг, romanized: Koryakskiy okrug; Koryak: Чав’чываокруг, Cav’cәvaokrug), or Koryakia (Russian: Корякия, romanized: Koryakiya), is an administrative division with a special status within Kamchatka Krai, Russia.

At the time, it had the smallest population of all the federal subjects, despite being ranked seventeenth in size, at 301,500 square kilometers (116,400 sq mi), encompassing part of the northern half of Kamchatka Peninsula.

The Koryakia branch of the Ministry of Emergency Situations said some area residents were injured but there were no fatalities.

The quake occurred at about noon local time Friday, so residents were awake and not caught in their beds.

The United States Geological Survey reported a series of at least fifty smaller aftershocks in the area and immediately offshore.
