Researchers, satellite -based communication can be seriously disrupted due to volcanic eruptions, he said. The ionosphere is the region of the Earth's upper atmosphere, where molecules and atoms are ionized by solar radiation and form positively charged ions. The area with the highest concentration of ionized particles is called the F, which is an area of an area of 150 to 800 km above the world surface.This region plays a very important role in long -distance radio communication by reflecting and breaking radio waves used by satellite and GPS monitoring systems to the surface of the world. However, according to scientists at the University of Nagoya in Japan, these publications can be interrupted by irregularities in the F region.Throughout the day, the ionosphere is ionized by the ultraviolet radiation of the sun and forms a density gradient of electrons with the highest density near the equator. However, these interruptions, known as equator plasma bubbles , can create very dense plasma areas that can delay radio waves and reduce GPS performance. Researchers looked at the Tonga Volkeeper explosion last year, the largest submarine burst in history.The team used ground-based ionospheric observations to monitor the Himawari-8 satellite to control the first arrival of air pressure waves to detect EPB formations to test their theories. After the pressure waves produced by the volcanic explosion, they observed an irregular structure of electron density along the equator. "The results of this study showed EPBs produced in the ionosphere in Asia, from the equator to low latitudes in response to the arrival of the pressure waves caused by submarine volcanic eruptions in Tonga," Shinbori said. The group also made an amazing discovery.For the first time, they showed that ionospheric fluctuations started a few minutes before the atmospheric pressure waves, which were included in the formation of plasma bubbles, considering that this occurred after the explosion before. "Our new finding is observed a few minutes before the first arrival of the shock waves triggered by the tonga volcanic eruption."Said. "This shows that the spread of rapid atmospheric waves in the ionosphere triggers ionospheric disorders before the first arrival of shock waves. Therefore, the model needs to be revised to take into account these fast atmospheric waves in the ionosphere.” They also found that EPB expanded much more than standard models. "Previous studies have shown that the formation of plasma bubbles in such high altitudes is a rare event and made it a very unusual phenomenon," Shinbori said.Said."We have found that the EPB, which is formed by this explosion, has reached even beyond the ionosphere, and that we should pay attention to the connection between ionosphere and cosmos when extreme natural events such as Tonga event occur." The study can help prevent satellite broadcasting and communication failures associated with earthquakes, volcanic eruptions and other events, which are the most trusted technology to help rescue efforts.
