Events in this collection
These records come from March 2020. Magnitude alone does not establish likely damage: depth, distance, local geology and building conditions also matter.

What this category includes
Event-level records
The index groups reports that were categorized at magnitude 5 or stronger when published. Individual pages may include preliminary time, location, depth and magnitude information.
- Historical event date and reported region
- Links to available individual archive pages
- Related magnitude and daily indexes
- Plain-language seismic reference material
Important limitations
Seismic agencies routinely refine early solutions as more station data becomes available. An archived headline is therefore not a substitute for a reviewed catalog.
- Magnitude does not predict damage by itself
- Remote events may have little observed impact
- Different agencies can report slightly different values
- Urgent instructions must come from local authorities
Common questions
Magnitude 5+ archive FAQ
What does “magnitude 5+” mean here?
It identifies reports categorized at magnitude 5.0 or stronger at publication. Later agency review may produce a different final value.
Is every magnitude 5 earthquake damaging?
No. Impact depends on depth, distance from communities, local ground conditions, construction and other factors.
Why can agencies list different magnitudes?
Agencies may use different station networks, data windows and magnitude scales. Values often converge as analysis is refined.
Are these current earthquake alerts?
No. The visible records are historical archive entries from March 2020, not live warnings.
Can a magnitude be revised below 5?
Yes. Preliminary estimates can move above or below a category threshold after additional seismic data is processed.
Where should I check during an emergency?
Use bulletins from your national seismic agency, civil-protection authority and local emergency services. Follow evacuation instructions immediately.
