What are the records of thermal anomalies?

There are many precursors before earthquakes, and thermal anomaly is a means to predict earthquakes that people have only recently discovered and paid attention to. People know little about it, but the latest data analysis may become one of the most reliable means to predict earthquakes in the near future.
