Earthquake & Tsunami Safety in Bali: Expat Survival Guide

Living in Bali long-term means accepting that this island sits on one of the most seismically active zones on Earth. The 2018 Lombok earthquakes, which were felt strongly across Bali and killed over 500 people regionally, were a wake-up call for many residents who had grown complacent. The 1979 Serangan tsunami and historical records from the 1917 Bali earthquake remind us this is not a theoretical risk. As an expat, building a personal emergency plan is not paranoia; it is basic responsible living here.

The first thing every Bali expat should do is assess their home location relative to coastal and fault-line risk. The south and southwest coastlines, including Seminyak, Canggu, Kuta, Jimbaran, and Nusa Dua, carry meaningful tsunami inundation risk if a large offshore quake occurs near the Sunda Trench or the Lesser Sunda fault systems. Inland areas like Ubud, Tabanan hills, and Bedugul sit at higher elevation and carry lower tsunami risk, though earthquake structural risk remains everywhere. Use the BMKG (Badan Meteorologi, Klimatologi, dan Geofisika) tsunami hazard maps, available at bmkg.go.id, to check the specific risk level for your neighborhood or villa.

When an earthquake begins, your immediate actions matter enormously. If you are indoors, drop to your hands and knees immediately, take cover under a sturdy table or desk, and hold on until the shaking stops. Move away from windows, ceiling fans, heavy shelving, and anything that can fall. Do not run outside during shaking because most injuries happen from falling debris as people move. If you are in a modern concrete building, the doorway myth is outdated; a table or interior wall is statistically safer. If you are outdoors, move away from buildings, walls, power lines, and trees, then drop and stay low.

After the shaking stops, your next 60 seconds are critical for tsunami preparedness. The BMKG issues tsunami warnings via its system, but you cannot always rely on receiving an alert in time, especially at night or if communications infrastructure is damaged. Apply the natural warning rule instead: if the shaking was long and strong, lasting 20 seconds or more, do not wait for an official warning. Move immediately inland or to high ground. A common expat mistake is waiting for confirmation on social media or WhatsApp groups. Do not wait. Walk, cycle, or drive away from the coast as fast as safely possible.

Every expat household should identify a tsunami evacuation route in advance. Walk your route in daylight before you ever need it. In Seminyak and Kuta, the inland road toward Denpasar and the Sunset Road corridor are primary escape arteries, but they can gridlock in a real emergency. Identify secondary foot paths and discuss them with your family or housemates. In Canggu, heading north toward Pererenan and then uphill toward Munggu or Cemagi gives you elevation quickly. In Sanur, the road toward Denpasar is your best option. Aim for at minimum 30 meters elevation above sea level; 50 meters is safer for a major event.

Build a go-bag and keep it accessible in your home. For expats in Bali, your go-bag should include: your passport and a printed copy of your KITAS or ITAS, your insurance card and emergency contact numbers, at least Rp 2,000,000 to Rp 5,000,000 in cash (approximately USD 120 to USD 310, as ATMs will not function after a major event), a basic first aid kit, a torch with spare batteries, a portable phone charger, three days of any prescription medication, a whistle, and a small supply of clean water. Store digital copies of all documents in a secure cloud folder as a backup.

Know where your nearest hospitals are and understand their capabilities. BIMC Hospital in Kuta and BIMC Nusa Dua are the most foreigner-familiar private facilities on the south coast and handle trauma and emergency cases. BROS (Bali Royal Hospital) in Denpasar is a strong local option. Sanglah Hospital (RSUP Sanglah) is the main government referral hospital in Denpasar and has the island's most advanced trauma capacity, though it is a public facility with a very different patient-to-staff ratio than private hospitals. In a mass casualty event, private hospitals will fill quickly; Sanglah will be the overflow center. Emergency numbers: 119 for national ambulance, 112 for general emergency, 110 for police.

Download the BMKG app on your phone and enable push notifications for earthquake and tsunami alerts. This is free and is the official Indonesian government tool. The app provides real-time magnitude readings, depth data, and tsunami threat assessments in English and Indonesian. Supplement this with the InaTEWS (Indonesia Tsunami Early Warning System) alerts, which BMKG broadcasts. Many expat communities also monitor the USGS Earthquake Hazards Program online at earthquake.usgs.gov for independent confirmation of large events. For radio backup if cell networks go down, a battery-powered AM or FM radio tuned to RRI (Radio Republik Indonesia) will broadcast official emergency updates.

Expats with children in Bali need an additional layer of planning. Confirm your child's school has a written earthquake and tsunami drill program and an emergency reunification policy. International schools such as Green School, Bali International School, and Canggu Community School have varying levels of disaster preparedness; ask the administration directly for their written plan. Know exactly what you are supposed to do if a disaster occurs during school hours and who your child will be released to if you cannot reach the school yourself. Designate a backup adult your child knows by name.

Your expat network is a genuine safety resource in a disaster. Join local community groups such as Bali Expat Community on Facebook, neighborhood WhatsApp groups, and local banjar (village community) networks. After the 2018 Lombok quakes, informal expat networks coordinated supplies and information faster than many official channels. Register your presence in Bali with your home country's embassy or consulate: Australian citizens can use the Smartraveller registration, US citizens use STEP (Smart Traveler Enrollment Program) at step.state.gov, and UK citizens use the FCDO travel registration. These registrations allow embassies to contact you and account for you after a major event.

Check your health and evacuation insurance covers natural disasters and emergency medical evacuation from Indonesia. Many basic travel policies exclude natural disasters or limit coverage to a short stay. For long-term expats, providers such as AXA, Cigna Global, Allianz Care, and Pacific Cross offer plans that include emergency evacuation and repatriation. Medical evacuation by air ambulance from Bali to Singapore or Australia typically costs USD 30,000 to USD 80,000 or more without coverage, which makes comprehensive insurance non-negotiable. As of 2026, confirm current plan details and exclusions directly with your provider.

Aftermath safety is often overlooked in earthquake planning. After the main shock stops and you have evacuated if needed, be aware of aftershocks, which can be significant and can trigger secondary building collapses. Do not re-enter a damaged building until it has been checked by a structural assessor. Be cautious of broken gas lines, exposed wiring, and contaminated water supplies. In the days after a major event, only use bottled or boiled water. Stock at least seven liters per person at home at all times as part of your household preparedness baseline. Keep your vehicle fuel tank above half-full as a routine habit so you can evacuate without stopping.

Finally, community preparedness matters as much as individual planning. Attend or encourage your neighborhood to participate in BPBD (Badan Penanggulangan Bencana Daerah) disaster drills. The Bali BPBD office, reachable at their Denpasar headquarters, periodically runs public tsunami evacuation exercises, particularly around October 13, which is the UN International Day for Disaster Risk Reduction. Learning basic Indonesian emergency phrases and knowing how to communicate with your banjar head (kelian banjar) about your household can make a real difference in a community-led evacuation. Being a prepared expat also means contributing to the safety of the community you have chosen to live in.
