Natural disasters such as volcanic eruptions and earthquakes are extremely harmful to humans, so people are actively exploring their prediction and forecasting. Miraculously, scientists have discovered that some "alarm plants" are good helpers for humans in this work.

Since the 1980s, scientists have conducted relevant research on whether plants can predict earthquakes. From the perspective of plant cytology, they have observed and measured changes in plants before earthquakes. After research, it was found that the cells of an organism are like a living battery. When they come into contact with two asymmetric electrodes of the organism, a potential difference is generated between the two electrodes and an electric current occurs.

After long-term and continuous observation and research, Professor Shimayama of Tokyo Women's University in Japan has conducted biopotential measurements on the Albizia Julibrissin tree for many years. After analysis, he found that the Albizia Julibrissin tree can predict earthquakes.

Albizia julibrissin trees are able to react before earthquakes with unusually large currents.

Relevant experts believe that this is because its root system can sensitively capture geophysical and chemical changes and magnetic field changes that are precursors to earthquakes.

According to the observation of a professor in the Soviet Union, earthquake flowers bloom out of season because of volcanic eruptions or precursors to earthquakes. That is, the generation of high-frequency ultrasonic waves causes earthquake flowers to bloom out of season.

This abnormal ultrasonic vibration caused the earthquake flower's metabolism to mutate, so the flower bloomed, warning people of an upcoming volcanic eruption or earthquake.

For example, before the earthquake, dandelions bloomed early in early winter; potato vines also bloomed unexpectedly; bamboos not only bloomed suddenly, but also died in large areas... These abnormal phenomena often indicate that An earthquake is about to happen.

Mimosa is a plant that is very sensitive to environmental changes. Under normal circumstances, the leaves of Mimosa pudica open horizontally during the day, and as night falls, the leaves slowly close. However, in the period before an earthquake occurs, the leaves of Mimosa pudica will close during the day and open inexplicably at night.

At 7 o'clock in the morning on January 11, 1938, the mimosa began to open, but at 10 o'clock, all the leaves suddenly closed. Sure enough, a strong earthquake occurred on the 13th. In 1976, members of the Japan Earthquake Club observed the abnormal closing phenomenon of mimosa leaves many times, which resulted in subsequent earthquakes.

Dandelions are found throughout the vast areas in the north and south of my country and are very adaptable. So, most people know and love dandelions.

Experts believe that during the process of earthquakes, huge pressure will be generated deep in the earth and electric current will be generated. The electrical current breaks down the water in the rock, creating charged particles. The charged particles are squeezed to the surface and then run into the air, producing charged suspended particles or ions, causing plants to produce abnormal reactions.

It is a fact that plants can sense earthquakes in advance. However, the abnormal responses of plants are not always caused by earthquakes. They may also be caused by weather changes, climate changes, changes in the natural environment, or other physiological changes.

Little knowledge, big vision

There is a peculiar wild flower growing on the active volcano Pangranga in Java Island, Indonesia. It is extremely sensitive to volcanic eruptions and can predict volcanic eruptions. After long-term observation, people found that it bloomed beautiful yellow flowers before the volcano erupted. At this time, people hurriedly left the volcano, so everyone called it the "message flower."
