1939 Erzincan earthquake struck on 27 December local time – magnitude of 7.8
Post: December 26, 2018
It seems time to ask science why the ignored a meteorological highly interesting weather conditions surrounding the 1939 Erzincan earthquake in December 1939. Due to Second World War Europe was in turmoil since 1st September 1939. Several highly extreme weather conditions had already occurred. During the closing days further ‘surprising’ weather conditions showed up the Barents Sea down to the Mediterranean, extreme low temperatures, extreme high air pressure, exceptional snow, culminating in a very destructive earthquake in Turkey on December 27th, 1939. It followed a rare tsunami in the Black Sea, with further weather implications, as summarized in a CHRONICAL (below). By the end of December 1939 to general weather condition in Europe including the entire Erzincan earthquake offer a huge set of information on “how weather works” under extraordinary conditions, that one can only wonder why science has shown no interest in understanding and explaining the situation almost eight decades ago.
It follows an excerpt from Chapter “B. Cooling of Europe”, Section: “141 Turkey Earth Quake – 27 December 1939 (2_51)” from the Book:Climate Change & Naval War
“Once more a great disaster has visited a country, caused this time not by man’s inhumanity to man, but by a gigantic force of nature.” – “It is not likely that the new upheavals will teach the geologist anything new. They are evidence that nature has not yet finished with the earth.” – “What we urgently need is some method of predicting quakes and warning a threatened population.” (Extracts from the NYT Commentary on 29 December 1939).
Weather conditions before the earthquake
First indications that Central Europe had been ‘conquered’ by an anti-cyclone weather system, preventing milder maritime air from flowing through the middle of the continent, were available in the first half of December 1939 itself. Most significant deviation from the average weather became visible just a week before the earthquake struck. Between 21st and 22nd, temperatures dropped to below minus 30°C in Finland north of the Arctic Circle.
Around the same time (20th December), Northern Turkey had two high pressures of 1,040 mb attracting cold air from Siberia via the Caspian Sea. A low pressure (1,010 mb) shortly took control over Southern Turkey on 22nd, the high pressure returned again with two centres on 24th (ca. 1,040 mb), the pressure centre above 1,040 over the location of the epicentre on 25th, increasing to above 1,045 mb on 26th (02 hours), which increased over Eastern Anatolia to ca 1,050 mb during the early morning and presumably remained high until the earth trembled violently.

What happened after the earthquake?
All information on the Anatolia quake for readers interested in news was published by the NYT. The New York Times did a marvellous reporting job under the prevailing difficult conditions. While the NYT even became almost philosophical in its comments on December 29, about geology, the meteorological impact of the quake is highly interesting for practical purposes as well. Did the quake and its meteorological side effects contribute to the emergence of the extremely cold war winter of 1939/40 in North Europe?
At the Turkish Black Sea coast, about 150 km away from the epicentre, the quake generated a strong tsunami wave of up to a metre height that crossed the eastern part of the Sea in less than one hour. Cont.

Snow also fell all over Bulgaria on December 21-22, starting a new cold weather episode (down to -16°C); on December 24th in Northern Bulgaria -20°C; December 25th until the earth quake in Turkey on 27th more moderate temperature below zero, showing no specific weather anomalies, (according to the Bulgarian newspaper ‘Zora’; by personal communication).
