    Scientific discovery by detecting the earth's magnetic anomaly can be warning tsunamis
    2016-03-04 10:34

    according to foreign media reports, the scientists found that could be early warning of tsunami occurred by magnetic anomaly, engineers from China, therefore created a model to simulate the earth's magnetic field and the relationship between the huge waves, the team said the study helps to build a tsunami early warning system, we can through the satellite orbit deployment to detect the magnetic anomaly caused by the tsunami, and then make a tsunami warning report. Huge tsunami waves are often related to the earthquake, which can be dozens of meters above sea level, if occurred in offshore waters, so dozens of meters of waves can destroy everything on land, a devastating impact. Tsunami in the ocean (sea) occurs, its height is not large, under the background of ocean wave interference may be more difficult to find.

    Although the tsunami has certain concealment, but its movement speed is very fast, and involves a large number of the rapid change of the water, because the water has certain salinity, tsunami fast moving small changes can lead to its conductivity appeared, through earth's magnetic Watson sensor field will cause magnetic anomaly, if we are in the deployment of a magnetic sensor satellite in orbit, or high altitude balloon, magnetic anomaly small changes can occur. According to Sumatra in 2004 and 2010, Chile tsunami recorded data, the team found that the magnetic anomalies related to the tsunami, then calculate the wavelength of tsunami waves, and tsunami heights. In principle, we can according to the magnetic anomaly signal quickly complete tsunami wave curve calculation, if the technology has been applied, can significantly improve the existing ocean tsunami warning system, improve the tsunami warning time.
    Undersea earthquake can trigger a tsunami, powerful waves reach the shore can engulf everything, the wave height can reach tens of meters, huge huge destructive


    But how to build magnetic anomaly detection of network covers the ocean? Researchers believe that magnetic anomaly detector can be deployed on high altitude balloon, or the low earth orbit satellites, can satisfy the magnetic anomaly signal detection, magnetic expert at the university of Colorado ma & midextnoggraphemekerify; Neil thought by tsunami magnetic signal system may have been successfully detected signal of magnetic anomaly caused by the tsunami. Participated in the task of scientists said the next step of work will focus on tests on Easter island tsunami waves, the team also plans to study wave, tidal and the relationship between magnetic effect, under the surface of the water of the sea water change of magnetic signal can be associated with abnormalities, and different between seawater exchange, is also a factor.
