Скачать или смотреть ChEESE: Mexico’s National Earthquake Drill 2025

On 19 September 2025, the ChEESE Centre of Excellence for Exascale in Solid Earth applied its urgent computing workflows during Mexico’s National Earthquake Drill, one of the world’s largest preparedness exercises.

Marking the 40th anniversary of the 1985 Michoacán earthquake, the drill recreated a magnitude 8.1 scenario with widespread impacts.

Using the MareNostrum 5 supercomputer at the Barcelona Supercomputing Center (BSC), ChEESE researchers demonstrated how advanced HPC-based simulations can transform seismic data into fast, actionable insights. In collaboration with the Mexican National Seismological Service (SSN), the workflow UCIS4EQ processed data in real time to support emergency decision-making.

Highlights of the ChEESE contribution:

Ran the largest earthquake simulation to date over a 1,000 km-wide domain
Solved 4.4 million mesh elements with the Salvus engine
Generated an ensemble of earthquake sources to capture uncertainties

By integrating European HPC innovation with Mexico’s monitoring networks, ChEESE showed how urgent computing can move closer to operational use in highly seismic regions.
