SASSLA – Digital Platform for Early Warning and Comprehensive Risk Management

Receive the official signal from the Mexican Earthquake Early Warning System (SASMEX), along with emergency notices and public announcements from Civil Defense authorities.

SASSLA APP provides personalized information when the Earthquake Early Warning (EEW) is triggered:

• Estimated Time of Arrival (ETA) of seismic waves at your location
• Approximate epicenter location
• Expected shaking intensity at your location (light, moderate, or strong)

[SASSLA APP REQUIRES INTERNET CONNECTION]

The EEW is a critical signal. It allows people to initiate preventive actions seconds before seismic waves capable of causing damage arrive.

⚠️ The EEW is not issued for every earthquake, only for those that pose a threat to your location.

SASMEX EARTHQUAKE DETECTION COVERAGE:

SASMEX detection coverage includes 96 seismic sensors placed throughout the most seismically active regions of the country, along the Pacific Ocean and the Trans-Mexican Volcanic Belt, covering the states of Jalisco, Colima, Michoacán, Guerrero, Oaxaca, and Puebla.

Its monitoring infrastructure relies on highly reliable, redundant, and resilient systems in electrical, electronic, computing, and telecommunications engineering, ensuring continuous operation 365 days a year.


EEW LEAD TIME:

SASMEX defines “lead time” as the interval between the moment the population hears the official seismic alert and the moment strong seismic waves reach the alerted location.

The system can provide approximately 20 to 120 seconds of lead time, depending on the distance between the earthquake epicenter and the user’s location.

For example, an earthquake originating off the Michoacán coast could provide over 100 seconds of lead time for Mexico City, while locations closer to the epicenter will have shorter lead times.


INNOVATION AND PRESTIGE OF SASMEX:

SASMEX is a 100% Mexican development built with modern technology. Through science and engineering by a highly experienced team in telemetry systems, electronics, geophysics, computer science, telecommunications, artificial intelligence, and advanced computing, it broadcasts alerts using the fastest earthquake alert algorithm in the world, implemented across its monitoring and warning systems—making it the world’s fastest seismic alert system.

SASMEX is a member of international organizations dedicated to disaster risk reduction. It actively participates in national and international events, forums, and symposia with seismology experts, and regularly hosts specialists from around the world at its headquarters in Mexico.

Some of its collaborators include:
• International Association of Seismology and Physics of the Earth’s Interior (IASPEI)
• United States Geological Survey (USGS)
• Electric Power Research Institute (EPRI)
• American Geophysical Union (AGU)
• Seismological Society of America (SSA)


SASMEX: THE ONLY OFFICIAL EARTHQUAKE ALERT SYSTEM IN MEXICO

SASMEX is recognized as the first earthquake early warning system in the world and a global pioneer in seismic alert development.

Its alerts are public and free of charge, and it is officially endorsed by federal authorities as the ONLY OFFICIAL seismic alert system in Mexico.
