Root Cause

Peru's national early-warning cell-broadcast/SMS system (Sismate, run via the Everbridge Consortium under MTC/INDECI oversight) was compromised on the night of 20 May 2026: attackers used a provider account to send a fake magnitude-8.7 earthquake alert plus a fabricated tsunami warning for the entire Peruvian coast, alongside unrelated hacker/political messaging. MTC confirmed the breach and INDECI stated the alert was false, noting earthquakes cannot be predicted and urging people to follow only official channels. A Sismate-branded message is therefore not, by itself, sufficient basis to act on a specific claimed magnitude or evacuation order.

Workarounds

85% success If you actually feel strong or prolonged shaking near the coast, self-evacuate to high ground immediately regardless of whether any SMS alert arrives — do not wait for or depend on a Sismate message either way
```
This is standard tsunami-safety guidance independent of the alert system: physically felt strong/prolonged shaking is itself the trigger to evacuate, per Lima-district civil defense guidance.

65% success Treat a Sismate/INDECI SMS with a specific advance-claimed magnitude or an incongruous/political message attached as suspect, and cross-check INDECI's and DHN's official social-media or web channels before mass-evacuating on the SMS's specific numbers alone
```
INDECI publicly confirmed the May 2026 incident and pointed people to official channels rather than trusting the SMS content itself.

Dead Ends

Common approaches that don't work:

Receive a Sismate-branded SMS/cell-broadcast claiming a specific earthquake magnitude and tsunami threat, and treat it as automatically authoritative because it uses the official system's name/format 40% fail
On the night of 20 May 2026, Sismate was compromised through a provider (Everbridge Consortium) account and used to send a false magnitude-8.7 earthquake alert with a fabricated coast-wide tsunami warning, plus content unrelated to emergency management (references to a hacker group and unrelated political claims). MTC confirmed the unauthorized access and INDECI issued a statement that the alert was false, explicitly noting that Sismate is not designed to predict earthquakes before they happen — so a message claiming to warn of an event 'about to happen' with a specific magnitude is itself a red flag, not a routine feature of the real system.
