 American scientists are testing a new monitoring system for detecting tsunamis from space. This system is called "Guardian" and is being tested in the Pacific Ocean's Ring of Fire. Over the course of 115 years (between 1900 and 2015), this area has experienced more than 750 tsunamis.

According to scientists from the Jet Propulsion Laboratory, the full name of "Guardian" is the GNSS Above Atmosphere Real-Time Disaster Information and Alert System. It works based on a global positioning system (GPS) and real-time data obtained from satellites.

It will track displaced air and charged particles:

When an earthquake occurs under the sea, land subsides, or a volcano erupts, it creates significant disturbances. These disturbances generate powerful waves, known as tsunamis. These waves propagate rapidly with great force, often reaching speeds of up to 800 kilometers per hour.

The "Guardian" system is considered an advanced version of the existing warning systems. It observes displaced air and charged particles from the ionosphere (ionized layer of the Earth's atmosphere) as precursors to the arrival of a tsunami. The ionosphere is the outermost layer of the Earth's atmosphere.

When tsunamis occur, a portion of the air is displaced, and this displaced air spreads as low-frequency sound gravity waves. According to NASA, these waves and charged particles disrupt the signals of navigation satellites. These changes can be observed as alerts.

Leo Martoyer, a scientist from the Jet Propulsion Laboratory, stated that they did not interpret the signal loss as a satellite malfunction but rather utilized it as natural hazard alert data. Scientists claim that this is currently the fastest monitoring system, as it issues alerts within 10 minutes of observing charged particles colliding with the ionosphere.

Now let's understand what the Ring of Fire is:

The Ring of Fire is an area where several continental and oceanic tectonic plates interact. When these plates collide, earthquakes occur, tsunamis are generated, and volcanoes erupt. The impact of the Ring of Fire can be observed from New Zealand to Japan, Alaska, and North and South America. Approximately 90% of the world's earthquakes and 78% of tsunamis occur within this Ring of Fire region.

This area spans about 40,000 kilometers. Approximately 75% of the world's active volcanoes are located in this region. The influence of the Ring of Fire is observed in 15 countries: Japan, Russia, the Philippines, Indonesia, New Zealand, Antarctica, Canada, the United States, Mexico, Guatemala, Costa Rica, Peru, Ecuador, Chile, and Bolivia.
