M4.2 Earthquake near Todi, Italy — 20 September 2025

Light earthquakes are widely felt near the epicentre and can rattle windows, dishes and hanging objects. Damage is uncommon and usually limited to cracked plaster or fallen loose items.

A magnitude 4.2 earthquake radiates roughly 30 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 272, which is below the USGS threshold of more than 600 for its significant-earthquake list. The ranking combines magnitude with available Did You Feel It responses and PAGER alert level; it is not a direct measurement of damage.

That is about 22:01 local solar time at the epicentre, late at night.

This event was shallower than 87% of the 46 earthquakes recorded in Italy in our catalogue and stronger than 54% of them.

The epicentre was located at 42.7804, 12.4276 — 1 km east of Todi. The closest other recorded event was a magnitude 3.2 earthquake 21 km northeast of here on 04 March 2025.

The nearest other settlements in our records are Bevagna (21 km northeast), Bolognola (66 km east-northeast), Siena (104 km northwest) and Monte Giberto (105 km east-northeast).

At 10 km this was a shallow earthquake. Shallow events release their energy close to the surface, so for a given magnitude they produce noticeably stronger shaking — and more damage — than deeper ones. Roughly three quarters of all earthquakes worldwide occur at shallow depths.

This catalogue does not ingest eyewitness responses, so it cannot confirm where this earthquake was felt. Based on magnitude alone, an event this size is often felt across the surrounding area. Its shallow focus makes stronger surface shaking more likely than for a deeper event of the same magnitude.

The USGS record does not carry a link to NOAA tsunami information. That field is not an all-clear and does not state whether a tsunami occurred. In this case, a damaging tsunami would be less likely because at M4.2 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; it occurred inland rather than beneath the sea floor. For an active coastal alert, use tsunami.gov or your local warning authority.

No further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event.

8 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 4.9 event near Ponte Sasso on 06 October 2025. This M4.2 event released about 11 times less energy than that event.

1 earthquakes have been recorded within 100 km of this epicentre in the past year, 0 of them in the past 30 days.
