The 2011 Van earthquakes occurred in eastern Turkey near the city of Van. The first earthquake happened on 23 October at 13:41 local time. The shock had a M_ww magnitude of 7.1 and a maximum Mercalli intensity of VIII (Severe).^[5] It occurred at a shallow depth, causing heavy shaking across much of eastern Turkey and lighter tremors across neighboring parts of the South Caucasus and Levant. According to Disaster and Emergency Management Presidency on 30 October, the earthquake killed 604 and injured 4,152. At least 11,232 buildings sustained damage in the region, 6,017 of which were found to be uninhabitable. The uninhabitable homes left as much as 8,321 households with an average household population of around 7.6 homeless in the province; this could mean that at least around 60,000 people were left homeless. The other 5,215 have been damaged but are habitable.^[7][8][9] A separate earthquake within the same earthquake system happened on 9 November at 21:23 local time (19:23 UTC). 38 people were killed and 260 people were injured in the 9 November earthquake.^[10]
