Q1'26.
Mexico City—home to 21.2 million residents and generating 35% of Mexico's GDP—faces two existential dangers that threaten the heart of Latin America's largest metropolitan area. The 1985 earthquake killed over 10,000 people, and despite advanced warning systems, the 2017 earthquake still claimed 228 lives. Meanwhile, in 2025 alone, 38 million cubic meters of floodwater overwhelmed the city's infrastructure.
These aren't theoretical risks. They are ongoing threats that endanger millions of lives and billions in economic output every single day.

Estimated Robots Fleet, to be deployed across 4,250 km² metropolitan area, each equipped with integrated seismic and weather monitoring capabilities
World's first unified earthquake and flood monitoring network delivering real-time threat detection
Not an enhancement—a complete transformation of Mexico City's disaster preparedness infrastructure
Tenshi Global transforms Mexico City from a reactive emergency response model into a predictive resilience system. This autonomous network provides 12-24 hour flood warnings versus the current 2-4 hours, while augmenting the proven SASMEX earthquake system with hyper-local ground motion intelligence that can save thousands of lives.
With estimates reaching as high as 45,000 people killed—entire generations of families lost in minutes
In 1985 dollars, representing catastrophic infrastructure destruction across the capital
Major structures collapsed throughout the city, leaving lasting scars on the urban landscape

The 7.1 magnitude earthquake on September 19, 2017 demonstrated both the power and limitations of Mexico's SASMEX early warning system. The system provided a crucial 60-second warning that prevented thousands of deaths—but 228 people still perished.
The earthquake occurred just three hours after the national earthquake drill, leading some residents to dismiss the alert as part of the exercise. More critically, SASMEX cannot detect crustal earthquakes originating near or under the city itself, leaving zero warning time for these close-proximity events.
Economic loss: $1.2 billion
The insight: Warning systems work, but precision and local intelligence are essential to maximize survival rates.
SASMEX provides only 60 seconds for coastal earthquakes located 300km away. Nearby crustal earthquakes provide zero warning time.
The system cannot measure real-time ground motion across neighborhoods, making neighborhood-specific response impossible.
Aftershock sequences go largely unmonitored, leaving residents uncertain about ongoing danger after the initial earthquake.
SASMEX was designed in an era before autonomous robotics, artificial intelligence, and distributed sensor networks—technologies that can revolutionize earthquake response.
Cubic meters of water fell during summer flooding, with July 31 alone bringing catastrophic rainfall
Additional cubic meters in September flooding combined with high winds, compounding infrastructure damage
Of metropolitan population (11 million people) lives in flood-prone State of Mexico municipalities
The 2025 flooding wasn't an anomaly—it's the new normal. Mexico City sits in the Valley of Mexico with no natural drainage, experiencing land subsidence up to 40cm per year in southern districts. Climate change is accelerating extreme rainfall events, turning what was once manageable into an existential threat.
Iztapalapa: 1.8 million residents face chronic flooding risk—the city's most densely populated and vulnerable borough.
Gustavo A. Madero: 1.2 million residents in flood-prone zones with aging infrastructure.
State of Mexico municipalities: Ecatepec, Nezahualcóyotl, La Paz—home to millions with inadequate drainage systems.
Each flood event compounds infrastructure damage, raises disease risk from sewage-contaminated water, and costs hundreds of millions in economic losses.
Each of the 1,248 autonomous robots deployed across Mexico City carries an integrated sensor suite that monitors both seismic activity and weather conditions simultaneously. This isn't two separate systems—it's a unified intelligence platform that understands how earthquakes and floods interact, compound, and threaten the city.
Resonance frequency sensors detect ground motion with 0.001Hz-100Hz precision. P-wave and S-wave velocity measurement enables real-time earthquake characterization and soil liquefaction prediction.
Neuromorphic DVS disdrometers measure individual raindrops (0.3-2.5mm diameter), wind speed, atmospheric pressure, temperature, UV index, and air quality—building hyper-local precipitation models.
High-resolution cameras with AI video analytics detect drainage blockages, building instability, exposed utilities, landslide precursors, and soil subsidence—the chronic threat undermining Mexico City.
Each robot autonomously navigates city streets, avoiding obstacles and repositioning as needed during emergencies.
Sub-meter accuracy ensures precise sensor placement and enables dynamic response to emerging threats.
156 distributed charging stations across the metropolitan area ensure continuous monitoring without gaps.
5G cellular plus mesh networking ensures data flows even if primary communications infrastructure fails during disasters.
Mexico's SASMEX system has saved thousands of lives since its creation 30 years ago. Tenshi Global doesn't replace SASMEX—it transforms it into something unprecedented: a dual-layer earthquake detection and response system that combines regional early warning with hyper-local ground motion intelligence.
This fusion creates four revolutionary layers of seismic protection that have never existed in any city worldwide.
Coastal sensors detect earthquake 300km away, triggering 60-second warning across Mexico City
1,248 robots simultaneously measure actual ground motion in neighborhoods across the city
Within 3 seconds, Emergency Operations Center receives confirmed magnitude, local building response predictions, and neighborhood-specific evacuation procedures
Instead of a single citywide alert, residents receive precision guidance: "Your neighborhood will experience moderate shaking—shelter in place" versus "Evacuate immediately—severe structural damage expected in your zone." This neighborhood-level intelligence saves lives by preventing both under-reaction and panic-driven over-reaction.
SASMEX cannot detect earthquakes that originate near or underneath Mexico City itself—shallow crustal earthquakes that provide zero warning time. These events, while less frequent than subduction zone earthquakes, are devastating because they strike without notice.
Tenshi's breakthrough: The distributed network of 1,248 seismic sensors can detect crustal earthquakes and provide 5-10 seconds of local warning—the difference between life and death when a building collapses.
Those seconds enable:

After the main earthquake, Tenshi robots continuously measure ground motion, detecting even minor aftershocks that indicate structural instability.
Machine learning algorithms analyze aftershock sequences, predicting high-risk aftershocks before they occur based on seismic patterns.
Instead of blanket evacuation orders, the system identifies which buildings and neighborhoods face highest aftershock risk, enabling targeted response.
Real-time structural health data allows authorities to determine which buildings can be safely re-entered and which require demolition, speeding recovery.
Not all neighborhoods face equal risk during an earthquake. Buildings on soft lake sediments experience amplified shaking. High-rise structures have different resonance frequencies than low-rise buildings. Tenshi's 1,248-robot network measures ground motion at street level throughout the city, enabling unprecedented precision in emergency response.
"Buildings on Paseo de la Reforma—immediate evacuation critical due to amplified ground motion and structural resonance"
"Residential areas 5km away on bedrock foundation—shelter in place, no evacuation necessary"
This replaces broad citywide alerts with actionable intelligence that prevents both casualties from under-reaction and chaos from unnecessary evacuation.
The difference isn't incremental—it's transformational. Eighteen hours of advance notice enables proactive protection instead of reactive rescue.
Neuromorphic DVS disdrometers measure each raindrop with 0.3-2.5mm diameter precision—technology previously unavailable at city scale
Characterization of raindrop size patterns enables prediction of flooding intensity and drainage system capacity needs
Measurement of fall speed indicates storm intensity and evolution, improving short-term precipitation forecasting
"Severe weather expected across Mexico City metropolitan area. Prepare for potential flooding. Monitor local conditions."
Result: Vague warning. Citizens don't know if they're at risk. Emergency services overwhelmed. Reactive evacuation after flooding begins.
"Northern slope of Lake Chalco zone expects 75mm of rain in 15 hours. Chalco Valley drainage overflow predicted in 14 hours. Recommendation: Activate Western Emitter Tunnel backup by hour 10. Pre-evacuate 2,400 residents in Zones 7B and 7C by hour 12."
Result: Actionable intelligence. Targeted evacuation. Pre-positioned emergency equipment. Infrastructure optimized. Damage prevented.
