Disaster warning by satellite positioning

By developing the technology of the current GPS (Global Positioning System), US scientists have developed an early warning system that will provide accurate information about the impending disaster.

Nature World News says the new type of warning system is being tested in southern California, to alert people of the risk of flash floods. In order to increase the predictability, scientists have upgraded GPS stations by integrating seismic sensors and meteorological sensors.

According to the research team, the GPS alert system predicts a period of 1-2 minutes before an earthquake, before a tsunami occurs for several tens of minutes, warning about an hour before a flash flood. and a few days before a harsh winter storm.

By analyzing shock waves after an earthquake begins, a new generation warning system is used to predict the strength of aftershocks that may emerge.

In addition, the warning system can also create maps throughout the region affected by the earthquake and form the basis for tsunami forecasting.

GPS networks can forecast weather with timely and important information, thus providing accurate data on any potential hazards. Experts will provide this warning to the people and thereby contribute to limiting the impact of the disaster.

Advances in the forecasting technology will be applied to public works, buildings and hospitals in the region to minimize disaster damage, said Yehuda Bock, a researcher. of the Scripps Institution of Oceanography, said.
