While GNSS treatment methods on earth are correct for such distortions, Guardian uses them as clues.
The software travels a data transmitted to more than 350 continuous GNSS soil stations worldwide. It can potentially identify evidence of a tsunami up to around 745 miles (1,200 kilometers) from a given station. In ideal situations, vulnerable coastal communities near a GNSS station could know when a tsunami was heading and the authorities would have up to 1 hour and 20 minutes to evacuate the low zones, thus saving lives and goods.
The network of GNSS stations around the world is key to this effort supported by the Space Geodesy project of NASA and the GNSS global network, as well as the global differential JPL GPS network which transmits the data in real time.
The Kamchatka event offered a timely case study for Guardian. One day before the earthquake off the northeast coast of Russia, the team had deployed two new elements that were in preparation for years: an artificial intelligence to exploit signals of interest and a prototype messaging system that accompanies it.
The two were put to the test when one of the strongest earthquakes ever recorded caused a tsunami traveling hundreds of kilometers per hour through the Pacific Ocean. Having been trained to identify the types of atmospheric distortions caused by a tsunami, the goalkeeper reported the human revision signals and was informed of experts in the matter.
In particular, tsunamis are most often caused by large underwater earthquakes, but not always. Volcanic eruptions, underwater landslides and certain weather conditions in certain geographic places can all produce dangerous waves. An advantage of Guardian is that he does not require information on what caused a tsunami; It can rather detect that it has been generated and can then alert the authorities to help minimize loss of life and goods.
Although there is no miracle solution to prevent a tsunami from giving land, “Guardian has real potential to help by providing open access to this data,” said Adrienne Moseley, co -director of the Australian Australian warning center. “Tsunamis do not respect national borders. We must be able to share data throughout the region to be able to carry out assessments on the threat of all the links. ”
