A change in the magnetic field could trigger a tsunami alert

Tokyo: Although we may have an interval of one or two minutes, changes in the earth’s magnetic field occur shortly before a tsunami caused by a seismic earthquake. Thus, by noting these changes, we can predict a tsunami.

According to scientists, even an interval of one or two minutes can save human lives. Based on this, tsunami alert and warning system can be improved. Although experts have known this for a long time, the decrease in the magnetic field in terms of sea level has been observed for the first time.

Zai Henglin, a geophysicist at Kyoto University in Japan, said a significant link between changes in the magnetic field and sea level has been discovered.
According to him, optical data, computer simulation and real world evidence show the same thing. In this regard, he has thoroughly analyzed the tsunami in the Samoa region in 2009 and the tsunami in Chile in 2010. The bottom line is that magnetic waves change as the waves rise above sea level.

However, this depends on the depth of the epicenter. At a depth of three miles (4800 feet) one minute interval can be found. With this change, even if the height of the waves increases by a few centimeters, it is known in the magnetic field.

If the electrical conditions and the exact depth of the earthquake site on the sea floor are known, it can further improve the prediction. But it should be noted that the farther away the epicenter of the earthquake is from the noise of coastal settlements, the better data can be obtained.
