Mount Ararat
The chronology of Holocene volcanic activity associated with Mount Ararat is documented by either archaeological excavations, oral history, historical records, or a combination of these data, which provide evidence that volcanic eruptions of Mount Ararat occurred in 2500–2400 BC, 550 BC, possibly in 1450 AD and 1783 AD, and definitely in 1840 AD. Archaeological evidence demonstrates that explosive eruptions and pyroclastic flows from the northwest flank of Mount Ararat destroyed and buried at least one Kura–Araxes culture settlement and caused numerous fatalities in 2500–2400 BC. Oral histories indicated that a significant eruption of uncertain magnitude occurred in 550 BC and minor eruptions of uncertain nature might have occurred in 1450 AD and 1783 AD. According to the interpretation of historical and archaeological data, strong earthquakes not associated with volcanic eruptions also occurred in the area of Mount Ararat in 139, 368, 851–893, and 1319 AD. During the 139 AD earthquake, a large landslide that caused many casualties and was similar to the 1840 AD landslide originated from the summit of Mount Ararat.
