Tsunami warnings in Indonesia: the window is minutes

Most people picture a tsunami warning system: an alert, a siren, time to react. For a distant earthquake that is roughly how it works. For a local one it is not.

The FCDO is explicit: "if a major earthquake or landslide occurs close to shore, follow the instructions of local authorities, bearing in mind that a tsunami could arrive within minutes."

Indonesia sits where it sits. The same advice notes that "earthquakes happen regularly" and lists tsunamis among the natural disasters the country experiences routinely. With a near-shore event, official warnings may simply not outrun the wave.

The practical translation is unglamorous: if you are on the coast and the shaking is strong enough that standing is difficult, treat that as the warning and move.

Preparation here is about thirty seconds of thought on arrival rather than any equipment.

• Know which way is inland or uphill from where you are sleeping. On a beach in the dark, that is not obvious.
• Ask the hotel about evacuation routes. Coastal properties in Indonesia generally have a plan; guests generally have not asked.
• Do not go to look. Receding water is not a spectacle, it is the wave gathering.
• Follow local authorities once instructions exist — they enforce zones and know the terrain.

Communications and power can fail after a major earthquake, so a plan agreed with the people you are travelling with beats a plan that depends on phones working.

Not where people expect, so it is worth being direct.

International health cover responds to injury and illness. It is not disaster cover, it does not make you safer, and it is not what gets you off a beach. In an event of this kind the thing that matters is where you go in the first two minutes.

What cover does do is afterwards, and in Indonesia that mostly means evacuation. Serious trauma is referred offshore, hospital capacity can be overwhelmed in an affected region, and the FCDO's baseline assessment of local medical care is that it "can be poor and some medical tests cannot be performed reliably".

So read the evacuation limit, and check whether it covers domestic transfer as well as international.

To be clear about scope: we do not sell travel-disruption or cancellation cover — delayed flights and washed-out plans are a different product. We are an insurance introducer for international health and life cover for people.

Pre-existing conditions are excluded and cover is governed by the Regency Assurance policy wording.
