Disaster Alerts Abroad, Country by Country
A disaster alert on your phone abroad arrives through that country's own system, in whatever language it supports, not automatically in Korean. We cover confirmed facts, with sources and check dates, for five countries: Japan, the US, Taiwan, Thailand, and Australia. We do not relay alerts ourselves; we only explain what arrives and in what language.

Japan pushes earthquake early warnings, tsunami warnings, and weather alerts to phones automatically through carrier emergency bulletins. JNTO's free Safety tips app relays the same alerts in 15 languages, including Korean.
Why it happens: The carrier default alert is Japanese-only, so a visitor can miss what's happening. Earthquake and tsunami warnings are seconds-critical.
What to do: Install the Safety tips app (free, App Store / Google Play) before you leave. It covers earthquake early warnings, tsunami warnings, volcanic warnings, heat warnings, and civil protection information.

The US sends tornado, flood, and AMBER alerts automatically to phones through Wireless Emergency Alerts (WEA). In October 2023 the FCC required carriers to support pre-translated templates in 13 non-English languages, including Korean, but the compliance deadline for carriers is June 12, 2028.
Why it happens: A rule being adopted is not the same as it working everywhere today. Before the deadline, alerts in some areas may still arrive in English only, depending on the carrier.
What to do: Check that Wireless Emergency Alerts is not turned off in your phone's settings (turning it off leaves only presidential alerts). No app is needed; a compatible phone receives it automatically.

Taiwan's National Communications Commission (NCC) broadcasts earthquake, tsunami, and typhoon alerts to every 4G/5G phone in the affected area through the Public Warning System (PWS) cell broadcast, no signup or app needed. Confirmed sample messages show a Traditional Chinese warning followed by an English one.
Why it happens: Glancing at Chinese-only text and moving on means missing the English that follows. Not knowing the alert's distinct tone and vibration (even on silent) can mean missing it entirely.
What to do: No app needs to be running to receive it. For more detail or aftershock updates, use the Central Weather Administration's own app.

Since 2025, Thailand's mobile carriers and the Department of Disaster Prevention and Mitigation (DDPM) have been sending disaster alerts via Cell Broadcast Service, with the first nationwide test across all 76 provinces on January 20, 2026. Carrier True says the system supports five languages: Thai, English, Chinese, Japanese, and Russian.
Why it happens: Because the system is new, assuming 'Thailand doesn't do this yet' means missing a real alert. The language actually used can vary by issuing agency and area.
What to do: There's nothing to turn on. Any phone on a Thai carrier network receives it automatically, with sound and vibration even in silent mode.

Australia's cell-broadcast national warning system, AusAlert, run by the National Emergency Management Agency (NEMA), is due to go live on 1 October 2026. It reaches every compatible device in the target area automatically, no app or active SIM needed, but at launch, messages will be in English only.
Why it happens: Hearing 'Australia now sends disaster alerts to phones' can create an expectation of Korean support that launch doesn't meet. More than one in five Australians speak a language other than English at home, which is part of why this is contested.
What to do: Learn a few key English alert words (evacuate, shelter, warning) before you go. Until AusAlert launches, the existing SMS-based Emergency Alert system is what's in use.
