CENAPRED is a single centralized technical/research body headquartered in Mexico City with no regional office network — the zones above are a general reference, not CENAPRED's actual structure.
CNSNS is centralized with no regional office structure — the zones above are a general reference, not CNSNS's actual structure.
CONAFOR coordinates through its own network of regional and state forestry management offices, not the Consejo Nacional de Protección Civil's 5 zones — the zones above are a general reference, not CONAFOR's actual structure.
SEMARNAT maintains one federal representative office in each of Mexico's 32 states rather than grouping into 5 zones — the zones above are a general reference, not SEMARNAT's actual structure.
Health delivery is organized into local "jurisdicciones sanitarias" within each state, and the national health council separately groups states into 4 regions for its own purposes — neither matches the 5 zones above, which are a general reference only.
Emergency scenario
Regulatory scenario
Shown once a country and an emergency scenario are selected above — only that country's own agencies appear. Select all three countries for the full continental roster.
Response scenario
Shown once a coverage area is selected above.
Select any combination of locations, hazards, response types, or agencies above to see what's active across North America.
Coverage shown here is illustrative of network structure across all three countries, not a live partner count — actual matches depend on your account, country, and the specific request. Agencies listed are examples of who may be involved, not a guarantee of jurisdiction or activation for any specific event.
How we source
Small operators first, large partners at scale — across all three countries.
ERNA doesn't lock a government customer into one size of partner. As a cross-border response moves from immediate impact to a sustained, multi-month emergency, the network shifts who it draws equipment and crews from — giving the requesting agency more dynamic control and a better cost profile at every stage.
Immediate response
Independent operators / small businessesLarger partner companies
Nearest capacity wins. Whichever country's independent operators are closest to the affected border region activate first, regardless of size.
Lower mobilization cost. Small operators typically carry lower minimum commitments than large fleet contracts — which matters before the true scope of the event is known.
Dynamic control. The requesting agency can scale the request up or down hour by hour without breaking a large standing contract.
The government customer's request is matched to the nearest independent operator, whose crew and equipment reach the people affected directly — often within the first response window.
Stabilizing response
Independent operators / small businessesLarger partner companies
Blended sourcing. As the scale of the event becomes clear, larger partner companies from any of the three countries are brought in alongside the independent operators already deployed.
Capacity without losing flexibility. Independent operators keep filling local gaps while partner companies cover the growing baseline demand.
Cross-border balancing. If one country's capacity is tapped, the network can shift the mix toward whichever country still has independent or partner capacity available.
Dispatch operations rebalance which responders — independent or partner — are actively serving which part of the affected population as the picture develops.
Sustained response
Independent operators / small businessesLarger partner companies
Large partner companies carry the base load. Standing tri-national contracts provide the fleet size and crew rotation a multi-month CBRNE-scale event needs.
Predictable, negotiated cost. Longer commitments unlock the per-unit pricing that only makes sense once duration is certain.
Independent operators stay in the mix. Smaller local operators keep covering region-specific gaps the larger fleets aren't positioned for.
The requesting agency's standing allocation keeps equipment rotating to the affected population for as long as the emergency runs — without renegotiating the request from scratch.
The sourcing mix shown is illustrative of the model, not a live allocation — actual sourcing depends on the specific request, available capacity in each country, and the requesting agency's own procurement rules.

When one country isn't enough, all three respond together.
Each country page on this site shows a single national response network. This page is the other half of ERNA: what the United States, Canada, and Mexico can do when their capacity is combined into one response.
Combined capacity
The network as a whole, not three separate ones.
Every listed piece of equipment and every staged asset in any of the three countries is visible to the same dispatch system — combination isn't a special mode, it's the default view.

How combination works
Four steps, the same for any border.
Combination isn't limited to one border — the same process applies whether the gap is on the US–Mexico line, the US–Canada line, or a request that needs capacity from both.
01
Demand exceeds local capacity
A national declaration creates demand — ambulances, ALS/BLS equipment, generators — beyond what's staged in that country alone.
02
Network-wide match
Dispatch checks availability across all three countries' staged and partner-listed equipment, not just the requesting country's inventory.
03
Cross-border dispatch
Assets move to the affected jurisdiction, coordinated with the receiving country's response authority.
04
Combined field operation
Resources from more than one country operate under a single coordinated response until the declared emergency closes.
What it looks like
Two examples of combined response.
These are illustrative scenarios, not live incidents — they show the kind of combination the network is built to handle.
US ↔ Mexico
Combined ambulance response
A short-term flood declaration in a northern Mexican state exceeds local ambulance capacity. ERNA routes partner ambulances from South Texas across the border into the same coordinated response.
US ↔ Canada
Shared generator staging
Generators staged near the US–Canada border ahead of a forecasted storm serve whichever side the storm actually hits, cutting the time between declaration and delivery.
All three
Long-term biological response
A sustained biological emergency draws on standing partner allocations from all three countries at once, rotated over the life of the response rather than dispatched as a single event.
ONE APP, THREE COUNTRIES
Every dashboard sees the combined network.
Whether you're a requesting agency in Nuevo León, a partner in Texas, or a provincial office in British Columbia, your dashboard's inventory and matching draw from all three countries — not just your own.
