📋 Tender Overview
Scientists from the IGP and the Universite Cote dAzur have developed the E3WS algorithm, a tool that can record and identify the occurrence of earthquakes in minimal time. The Ministry of the Environment (Minam), through the IGP, has published the results obtained from its research in the prestigious scientific journal Journal of Geophysical Research: Solid Earth, on the development of this algorithm using Machine Learning (ML). E3WS was designed to identify, locate and estimate the magnitude of an earthquake using the first three seconds of the signal recorded by a single station. In this way, E3WS surpasses traditional alert systems, which require multiple stations and a longer time.
This innovative development, the result of the work of researchers Pablo Lara, Adolfo Inza, Hernando Tavera and Jose Tacza from the IGP, together with Quentin Bletery and Jean-Paul Ampuero from the Universite Cote dAzur, presented a solution that changes the traditional methods for calculating the hypocentral parameters of earthquakes. E3WS achieves an unprecedented balance between speed and precision for estimating the magnitude and location of the earthquake, critical factors in the early warning of earthquakes.
The algorithm was trained with more than 22,000 seismic events from highly seismic regions such as Peru, Chile, and Japan, as well as data from the Stanford Earthquake Dataset (STEAD). The results provided a 99.9% success rate in detecting earthquakes and high accuracy in estimating magnitudes and locations, particularly for events smaller than M7.2.
Currently, E3WS is in operation in Peru as part of the Peruvian Seismic Alert System (SASPe), a project led by the Geophysical Institute of Peru. Dr. Hernando Tavera, executive president of the IGP and head of the project, explains that the progress achieved using AI makes a difference in critical situations, allowing for rapid alerts and thus providing additional time for people to take preventive measures in the event of earthquakes with magnitudes equal to or greater than M6.
