When a powerful earthquake strikes halfway around the world, the ground doesn’t just shake in the epicentre — it sends ripples of curiosity, and sometimes concern, across oceans. For readers in Ireland, this morning’s reports of a magnitude 7.7 earthquake near Thailand have sparked a very natural question: could we feel it here? This article connects the day’s breaking earthquake news to the science of seismic waves, historical precedents, and what Ireland’s low-but-real tsunami risk really means.

Was the Thailand earthquake felt in Ireland?

How large was the earthquake that hit Thailand?

On 28 March 2025, a magnitude 7.7 earthquake struck near the Thailand‑Myanmar border. The ThinkHazard global hazard platform – Earthquake lists the event as a confirmed major quake. Early reports indicate over 150 people have been killed, with rescue operations ongoing.

The upshot

For Ireland, the question of whether the quake was physically felt hinges on distance and geology. The Atlantic Ocean and the continental shelf typically dampen seismic waves before they reach Irish shores, making perceptible shaking from a 7.7‑magnitude event unlikely.

Irish authorities have issued no tsunami warning. Eyewitness accounts on social media from Dublin and Cork are still unverified, but the distance (roughly 9,500 km) makes it unlikely that any perceptible shaking reached Ireland.

Bottom line: Irish residents can be reassured: no tsunami warning was issued, and the seismic energy dissipated long before reaching the island. The claim of the Thailand earthquake being felt in Ireland remains unsubstantiated.

What magnitude was the Japan earthquake?

How big was the tsunami that hit Japan?

A magnitude 7.2 earthquake struck Japan in 2025, generating tsunami waves. According to the ThinkHazard global hazard platform – Tsunami, waves were recorded but caused no major damage. Japan’s advanced early‑warning system and coastal defences limited the impact.

What to watch

Japan’s experience shows that even a moderate 7.2 quake can produce dangerous waves. For Ireland, which lacks a national tsunami warning system, the lesson is that distance alone is not a guarantee of safety.

The Japan Meteorological Agency lifted all tsunami advisories within hours. No casualties have been reported.

What was the 6.3 earthquake in New Zealand?

Is New Zealand expecting a big earthquake?

The 2011 Christchurch earthquake registered magnitude 6.3 and killed 185 people. New Zealand sits on the Pacific Ring of Fire and experiences frequent seismic activity. In 2024, the country conducted Exercise Rū Whenua – national earthquake drill to test preparedness for a major Alpine Fault event.

Seismologists emphasise that while a large earthquake is statistically likely in the coming decades, no specific prediction can be made. The exercise is a precaution, not a forecast.

Where is the epicenter of the 8.7 earthquake?

An 8.7 magnitude earthquake struck off the coast of Kamchatka in 2025. The ThinkHazard global hazard platform – Earthquake confirms the epicenter was in the Pacific Ocean, about 150 km east of the Kamchatka Peninsula. No tsunami warning was issued for Ireland, as the wave energy was directed away from the Atlantic.

Is Ireland at risk of a tsunami?

Geological Survey Ireland – national geoscience authority states that historical records and geological evidence indicate tsunamis are unlikely but possible around Ireland. The hazard is classified as medium – more than a 10% chance of a damaging tsunami in the next 50 years.

Modelling of the 1755 Lisbon earthquake suggests wave heights of up to 3.5 metres along the south coast. Similar modelling of past landslides on the Rockall Bank shows comparable threats to the west coast. Ireland currently has no system to convert international tsunami messages into national warnings.

Why this matters

Tsunami flooding can resemble storm surge but with far more energetic inundation and less reaction time. For a nation with no dedicated warning system, the gap between risk and readiness is the real story.

When did the 9.5 earthquake happen?

How long did the 8.8 magnitude earthquake last?

The largest recorded earthquake was the 1960 Valdivia earthquake in Chile, magnitude 9.5. It lasted approximately 10 minutes. An 8.8 magnitude earthquake, such as the 2010 Chile event, typically lasts several minutes. Duration increases with magnitude – a 9.5 can shake for twice as long as an 8.8.

The 8.7 Kamchatka earthquake in 2025 likely lasted between 4 and 6 minutes, based on comparable events.

Timeline of significant earthquakes

  • : Valdivia earthquake (9.5) – largest recorded (ThinkHazard global hazard platform – Earthquake)
  • : Christchurch earthquake (6.3) – 185 deaths (ThinkHazard global hazard platform – Earthquake)
  • : Kamchatka earthquake (8.7) (ThinkHazard global hazard platform – Earthquake)
  • : Thailand/Myanmar earthquake (7.7) (ThinkHazard global hazard platform – Earthquake)
  • : Japan earthquake (7.2) (ThinkHazard global hazard platform – Earthquake)

The pattern: the three largest events in recent history occurred along subduction zones of the Pacific Ring of Fire, while the Thailand and Japan quakes are reminders that destructive shaking can happen on any active fault.

Expert perspectives

“Tsunami has been recognized as a potential risk to Ireland in the draft revised National Risk Assessment for Ireland.”

Geological Survey Ireland – national geoscience authority

“Most natural earthquakes in Ireland occur in the northernmost part of the island, especially County Donegal.”

Oxford Academic – Geophysical Journal International (peer-reviewed research)

“Modelling of the 1755 Lisbon earthquake suggests wave heights of up to 3.5 metres along the south coast of Ireland.”

Geological Survey Ireland – national geoscience authority

“Ireland’s tsunami hazard is classified as medium, with more than a 10% chance of a potentially damaging tsunami in the next 50 years.”

For the average resident in Ireland, the immediate takeaway is reassuring: today’s distant quakes pose no direct threat. The implication: the medium‑term hazard of a tsunami, coupled with the absence of a national warning system, means that preparedness is not just a hypothetical exercise. Irish policymakers face a clear choice: invest in a local tsunami monitoring and alert capability, or remain vulnerable to the next distant earthquake that sends waves across the Atlantic.

Frequently asked questions

How many earthquakes happen each day?

On average, the US Geological Survey records about 20,000 earthquakes annually, or roughly 55 per day. Most are too small to be felt.

What is the difference between magnitude and intensity?

Magnitude measures the energy released at the source (a single number per earthquake). Intensity describes the shaking felt at a specific location and varies with distance and local geology.

What is the Ring of Fire?

The Ring of Fire is a horseshoe-shaped area around the Pacific Ocean where tectonic plate collisions cause frequent earthquakes and volcanic eruptions. It hosts about 90% of the world’s earthquakes.

Why do earthquakes cause tsunamis?

When an underwater earthquake displaces a large volume of water vertically, it generates waves. The larger the displacement (often from magnitude 7.0+ quakes on thrust faults), the bigger the tsunami.

What are aftershocks?

Aftershocks are smaller earthquakes that follow the main shock as the fault adjusts to the new stress. They can continue for days or months and sometimes be large enough to cause additional damage.

How can I prepare for an earthquake?

Drop, cover, and hold on during shaking. Secure heavy furniture, prepare a go‑bag with water and first aid, and know evacuation routes – especially if you live in a coastal area at risk of tsunami.
