For example, a flower grows on the slope of a volcano in Java, Indonesia, which can accurately predict volcanic eruptions and earthquakes. It is observed that if this flower blooms untimely, it means that there will be a catastrophe in this area, either a volcanic eruption or an earthquake. It is said that its accuracy rate is over 90%, and this flower is called "earthquake flower".
Professor Shimayama of Tokyo Women's University in Japan has measured the biological potential of Albizia Albizia for many years after long-term observation and research. Through analysis, it is found that the biological potential of Albizia Albizzia tree will change greatly before the earthquake.
In the "plant kingdom", plants that can predict earthquakes include mimosa, which is extremely sensitive to climate change. The leaves of mimosa usually open horizontally during the day and close at night. Because this kind of grass is very sensitive to the environment, when it comes into contact with people's hands, feet, clothes or exhaled gas, its leaves will be folded shyly and quickly, making people unable to see its leaves clearly. Therefore, people named it "mimosa". Mimosa is very sensitive not only to human body, but also to earthquake phenomena. Before the earthquake, the leaves of mimosa will be uncharacteristically closed without opening during the day and semi-open or fully open at night. Scientists have found that when the state of mimosa leaves changes abnormally, it indicates that a major earthquake will occur in this area.
