Timeline: how we got here

Here's a brief timeline of the events leading up to and following the earthquake:

25 October 2023, 23:23 BST: The earthquake strikes north-west England.
25 October 2023, post-23:23: Residents report feeling tremors and hearing loud bangs in various towns.
26 October 2023: Emergency services confirm no injuries or damage, but maintain a presence in the area.

What’s new vs what’s known

New today/this week

New reports indicate that the earthquake was felt across a wide area, with over 1,000 reports collected on Volcano Discovery, including from places as far away as Blackpool. Most residents described the experience in alarming terms, highlighting the intensity of the tremor.

What was already established

The BGS has previously stated that it detects around 300 earthquakes annually in the UK, although only a fraction (approximately 10%) are felt by the public. This serves to highlight that while seismic activity is not uncommon, significant tremors that cause noticeable sensations are relatively rare.

Impact for the UK

Consumers and households

For most households in the affected areas, the earthquake has caused little more than a fright. Reports of rattled fixtures and loud noises may lead to temporary anxiety, but with no injuries or structural damage reported, normal life is expected to resume quickly.

Businesses and jobs

Businesses in the regions impacted may see a temporary increase in customer inquiries related to safety and structural concerns, although no significant disruptions to business operations have been noted as of yet. The local economy is likely to remain stable following this minor seismic event.

Policy and regulation

No immediate policy changes are expected as a result of the earthquake. However, this event may prompt discussions about emergency preparedness and public safety protocols in areas at risk of seismic activity.

Numbers that matter

3.3: The magnitude of the earthquake reported by the BGS.
1.86 miles: The depth at which the earthquake occurred.
12 miles: The distance from the epicentre to the towns of Kendal and Ulverston where tremors were felt.
300: The average number of earthquakes detected annually in the UK by the BGS.
10%: The approximate percentage of detected earthquakes that are felt by the public.

Definitions and jargon buster

Magnitude: A measure of the energy released by an earthquake, with higher numbers indicating more powerful quakes.
Epicentre: The point on the Earth's surface directly above where an earthquake originates.
Seismic activity: The frequency and intensity of earthquakes in a given area.

How to think about the next steps

Near term (0–4 weeks)

Residents are encouraged to remain vigilant for any aftershocks, although none are expected to be significant. It is advisable to check homes for any minor damages that may have occurred unnoticed during the tremor.

Medium term (1–6 months)

Local authorities may consider reviewing emergency procedures and public safety protocols in light of the earthquake, particularly in regions that have not experienced such tremors recently.

Signals to watch

Monitoring for any aftershocks in the coming weeks.
Public safety announcements from local authorities regarding earthquake preparedness.
Updates from the BGS regarding any subsequent seismic activity in the region.

Practical guidance

Do

Stay informed through local news and updates from the BGS.
Check your home for any signs of damage post-earthquake.
Ensure your emergency kit is stocked and accessible.

Don’t

Don’t dismiss reports of the earthquake; they can be important for understanding seismic activity.
Don’t panic if you experience tremors; most earthquakes are minor and non-damaging.
Don’t ignore emergency preparedness; review what to do in case of future seismic events.

Checklist

Verify all family members are safe and accounted for.
Assess your home for structural integrity.
Review emergency plans and contact information.
Stay connected with community resources for updates.
Consider discussing earthquake preparedness with neighbours.

Risks, caveats, and uncertainties

While this earthquake was minor, it serves as a reminder of the potential for seismic activity in the UK. It is essential to understand that while the BGS monitors earthquakes, not all seismic events will be felt or reported. Residents should remain aware of emergency protocols but avoid unnecessary alarm.

Bottom line

The 3.3-magnitude earthquake that rattled north-west England on 25 October 2023 has raised awareness about seismic activity in the region. With no reported injuries or damages, life is expected to return to normal quickly. However, this incident underscores the importance of being prepared for future seismic events and understanding the impacts of such occurrences.

FAQs

What should I do immediately after feeling an earthquake?

If you feel an earthquake, stay calm, check for injuries, and assess your surroundings for any potential hazards. If you're indoors, seek cover under a sturdy piece of furniture.

Is a 3.3-magnitude earthquake dangerous?

A 3.3-magnitude earthquake is typically considered minor and is unlikely to cause significant damage or injury. However, it can be alarming to experience.

How can I prepare for future earthquakes?

Preparing for future earthquakes involves having an emergency kit, knowing safe shelter spots, and having a communication plan with family members.
