Real-time seismic monitoring and early warning

Mexican Earthquake Early Warning System in Oaxaca

In partnership with USAID and AXA Insurance, Grillo One sensors have been deployed across Oaxaca and Guerrero, Mexico to strengthen the country's earthquake early warning capabilities. This implementation provides critical coverage in two of Mexico's most seismically active regions, delivering real-time alerts to vulnerable communities and enabling rapid emergency response.

“The Grillo One network has proven its capability by detecting and characterizing seismic events, providing crucial early warning time for communities across Oaxaca and Guerrero.”
