Korea No Gaps in Alerts / disaster information 3-tier delivery network
Korea is rolling out a nationwide disaster information 3-tier delivery network that links local governments → village-level systems → vulnerable groups into one layered pipeline. The goal is simple: make sure every resident receives clear, actionable alerts—without duplication or delay. In life-threatening events like extreme rainfall, wildfires, or evacuation orders, phones will sound at maximum device volume (≈40 dB or higher) via an emergency alert; for seniors and people with disabilities, trained helpers will physically visit to deliver information and support evacuation. Text alerts will be strictly tiered by risk, move from 90 to 157 characters over time, adopt standardized templates that say “when/where/how,” and reduce spam through de-duplication and future geofencing. This guide translates the new disaster information 3-tier delivery network into what you need to set up today—settings, checklists, scenarios, FAQs, and a call to action.
1) One-page overview — what changes and why it matters
The disaster information 3-tier delivery network integrates three layers for redundancy with less noise.
① Local government (core signal)
Risk-based alert types—safety notice / emergency alert / critical alert. In critical cases, phones ring at maximum volume. Standard messages will specify time, destination, and action. Message length expands to 157 characters. System upgrades add duplicate filtering and, longer-term, geofencing to block irrelevant out-of-area alerts. Clear roles: basic municipalities handle evacuation guidance; metro/provincial and central agencies push broader forecast information.
② Village level (dense reinforcement)
Because text alone can miss people, all local warning facilities—village PA systems, LED boards, sirens—will rebroadcast urgent/critical alerts. Smart village broadcasting expands: with prior consent, residents in high-risk zones get automated voice calls. During network outages, local governments can request disaster broadcasting to deliver evacuation orders.
③ Vulnerable groups (the last mile)
For seniors, people with disabilities, and mobility-limited neighbors, the disaster information 3-tier delivery network activates evacuation helpers / community patrols who visit in person, provide shelter locations in advance of storms, and escort priority evacuees to safety.
2) Text alerts are changing — here’s how to read them
• Clear risk tiers
Safety Notice (low-risk info), Emergency Alert (serious threat), Critical Alert (immediate action). Critical alerts trigger the phone at maximum volume for instant attention.
• Standard templates + longer messages
Templates will explicitly answer When to move, Where to go (named shelters/landmarks), and How to act (evacuation routes, driving bans, power-off steps). Capacity grows from 90 to 157 characters to fit precise instructions.
• Fewer duplicates, less fatigue
De-duplication logic will weed out near-identical alerts; R&D is underway to add geofencing that blocks non-local alerts that erode trust.
3) Immediate setup checklist (do this now)
Phone settings
- Ensure Emergency/Disaster Alerts are ON (check both system and carrier apps).
- Allow Emergency Alerts to bypass Do Not Disturb.
- Create a family/work chat rule: reply “Alert received” to confirm receipt.
Home & workplace
- Pre-select two shelters/high-ground and rehearse routes.
- Pack a 72-hour kit: water, flashlight, power bank, first aid, prescriptions, copies of IDs.
- Assign a helper for vulnerable residents (elderly, disabled, infants, pets).
Community
- Locate village PA speakers / LED boards; opt-in to smart voice calls if available.
- Register as an evacuation helper via your community office / residents’ committee.

4) Scenario playbook — interpreting “when/where/how”
① “River ○○ overflow risk — move to △△ Shelter now”
Treat as a critical alert in the disaster information 3-tier delivery network. Avoid driving through flooded roads; go on foot toward designated high ground. Confirm that vulnerable neighbors are moving with you.
② “Wildfire spreading — avoid ○○ Road; evacuate to the west”
Move opposite wind/smoke direction, keep roads clear for responders, avoid parking along evacuation routes.
③ “Dam release — low-lying areas at risk”
Stay away from basements/riverbanks, shut off power if safe to do so, move to listed high-ground shelters, follow village rebroadcasts.
5) Beating duplicates and rumors
- If multiple messages arrive, follow the first valid instruction from your jurisdiction; later duplicates often mirror it.
- Do not share unverified SNS posts. Trust only local government/MOIS channels and village rebroadcasts.
- If networks fail, tune to radio / in-car DMB and listen for on-site loudspeaker guidance.
6) Protecting vulnerable neighbors — your role
- Add a line on your household plan with helper name & phone; require buddy-system evacuation.
- Audit routes for wheelchairs and walkers; assume elevators may be offline.
- Prepare a separate pouch for hearing aids, canes, meds; share emergency contacts with caregivers.
Summary
The disaster information 3-tier delivery network replaces one-channel texting with a layered system: local government alerts (risk-tiered, louder, clearer, longer), village rebroadcasts (PA, LED, automated voice calls, expanded disaster broadcasting rights), and in-person support for vulnerable residents. It adds duplication control and future geofencing to restore trust. Your job: enable alerts, plan shelters and routes, prep a 72-hour kit, and commit to last-mile support for neighbors. When alerts arrive, act on the first official instruction and rely on village/municipal channels—not rumors. With preparation, the disaster information 3-tier delivery network becomes a real safety net, not just a new name.

FAQ
Q1. What if I disabled disaster alerts?
Turn them back ON and allow them to bypass Do Not Disturb. Missing a critical alert can be life-threatening.
Q2. Why am I getting the same alert multiple times?
Multiple authorities can send similar notices. The upgraded system will apply de-duplication and, in time, geofencing to cut noise.
Q3. Where do I get info during network outages?
Listen for village PA, LED boards, radio/in-car DMB, and official loudspeakers. Local governments can request disaster broadcasting.
Q4. Why boost message length to 157 characters?
To fit precise “when/where/how” instructions that reduce confusion and speed evacuation.
Q5. Can I help elderly neighbors evacuate?
Yes. Register as an evacuation helper with your community office to coordinate safely with officials.
Q6. How will foreign residents get instructions?
Local governments provide multilingual notices; communities can keep pictogram-based action cards in chat groups for quick reference.
Conclusion
Systems save lives only when people connect the last mile. Spend ten minutes today enabling Emergency/Disaster Alerts, adding them to Do-Not-Disturb exceptions, and identifying two shelters/high-ground routes for your family. Add a 72-hour kit to your entryway, and message your building chat to adopt a simple rule: “Reply ‘Received’ to critical alerts.” Ask your community office about joining the evacuation helper list for vulnerable neighbors. The disaster information 3-tier delivery network is designed to reach everyone—but it becomes truly gap-free when you prep, practice, and help someone nearby.
