Study of the Relationship between Earthquakes and Weather in Recent Earthquakes in Iran

Earthquakes have long been associated with change and destruction. Human has always been looking for a solution to identify and predict the occurrence of earthquakes. In order to identify the occurrence of an earthquake, other events that can be a sign of the conditions of the earthquake should be examined. In order to study these conditions, the status of climatic variables in hourly, weekly and monthly time periods was studied. Even theories about the relationship between weather and earthquakes have long been proposed by the ancient Greek philosopher (Aristotle) called "earthquake weather". He proposed the theory that the weather would be warm and calm before the earthquake, and the next theory he stated was that earthquakes occur in calm and cloudy conditions. The U.S. military has since examined the relationship between the weather and its relationship to earthquakes.Identifying the relationship between weather and earthquakes can help to predict and reduce financial and life losses, so in this research, the weather conditions at the time of the earthquake in some of the major earthquakes of Iran have been investigated.  In this article, using the hourly, weekly and monthly data, the observed meteorological variables at the time of the earthquake were investigated. These variables include: Temperature (in degrees Fahrenheit), Dew point (in degrees Fahrenheit), Relative Humidity (in percent), Wind direction and wind speed (in meters per hour), Gusty wind (in meters per hour), Pressure (in inches), Precipitation (in inches), Cloud Cover, Solar Altitude, Lunar Altitude, General Weather Conditions on an hourly, daily, weekly and monthly basis can be named boards that were examined. The studied variables from the time before the earthquake to after the specified time intervals were examined. Due to the large number of these charts, data and maps, only some of them were presented as examples in this article. Based on the study, these two theories are rejected due to the impossibility of generalization to all earthquakes, and it is suggested that it is due to the occurrence of a series of simultaneous changes in the Earth's system, including the biosphere, lithosphere, hydrosphere and atmosphere.Based on the observed data, changes can be seen in most of the weather factors at the time of the earthquake. Air temperature, dew point, lunar altitude, solar altitude, relative humidity increased and then decreased, pressure decreased and then increased. The direction of the wind changed at the moment of the earthquake and as it can be seen, the direction of the wind was not observed at the time of the earthquake in any of the hours of that day. The wind speed has decreased at the moment of the earthquake. These changes in a system that includes cryosphere, biosphere and atmosphere.It happens in a moment and this change can be clearly seen in most weather factors. It is suggested that these changes be known as the "Earth Systemic Evolution Theory".These changes can be known as the "Earth System Evolution Theory". This theory is presented for the first time in this article.
