Why does it get cold and snowy after the earthquake?

As far as the degree of earth science research is concerned, there is no obvious connection between earthquakes and climate change. After some earthquakes in history, there was heavy rain or rainstorm. For example, four or five years ago, there was a heavy rain after the earthquake in Yunnan. Some earthquakes will cause volcanic eruptions and tsunamis, such as the earthquake in Chile, which should not be a problem of climate change. Looking forward to the progress of science and technology, we can answer this question.
