The issue of earthquakes in the CrimeanAbnormal Gas Emissions region is relevant from the perspective of historical seismology. A list of documented catastrophic earthquakes in Crimea is presented, borrowed from scientific and artistic sources, including individual facts and myths, reasonable assumptions, and hypotheses in connection with gas emissions from the Black Sea. Of particular interest is a detailed historiographical review of Crimean earthquakes of antiquity and the Middle AgesMiddle Agesby the historian V.V. Khapaev, 2008. This author critically examined the reliability of ancient written evidence, which very poorly covers the Black Sea earthquakes. The most significant references to these natural catastrophic phenomena are described fragmentarily. In total, 77 strong earthquakes have occurred in Crimea from the fourth century AD to the present. Despite many scientific publications, the question of the role of earthquakes in the history of the Crimean Peninsula remains insufficiently studied. Based on historical information, the most powerful earthquake near Yalta occurred in the fifteenth century, approximately in 1427 (1450 ± 50) with a magnitude of 7.5 ± 0.3. After the earthquake, desolation in Yalta lasted 70 years. The most destructive earthquake in the twentieth century occurred in Crimea in 1927. The first occurred on June 26, followed by another on 11 September 1927. The issue of earthquakes in the Crimean region is very significant from the point of view of historical seismology. Below is a list of documented catastrophic earthquakes in Crimea, borrowed from the literary sources at our disposal. The list does not claim to be comprehensive or reliable. We have tried only to outline briefly the individual facts and myths, reasonable assumptions, and hypotheses in connection with gas plumes of the Black Sea.
