EARTHQUAKE DETAILS

Albania [Land]

25 months ago · 30 Jul, 00:03

A weak earthquake, felt by some of the population. At this depth the shaking is felt, but rarely causes damage.

Stronger than 98% of Italian events in the past year

Epicentre at sea

The epicentre is at sea: for the same magnitude, the shaking is felt less on land, because the energy fades along the way before reaching the coast.

How far away could it be felt?

An estimate of how far people may have felt this quake.

  • up to ~10 km · felt only by some, at rest

The coloured rings on the map below show these distances.

Statistical estimate from the Italian intensity attenuation model (INGV): actual perception depends on geology, buildings and depth. Very shallow events can be felt locally even below the threshold.

The energy released

How much energy this quake unleashed, translated into everyday comparisons.

477kgof TNT equivalent
2.0 lightning bolts
M3
About the same energy as a magnitude 3 earthquake
M2this quakeM4

Each extra magnitude unit releases about 32 times more energy: an M5 is not "a bit stronger" than an M4 — it is a different league.

Energy estimated with the standard Gutenberg–Richter relation; an average lightning bolt ≈ 1 billion joules. Indicative values.

How deep it was born

11 km
medium depth
1.2 times the height of Mount Everest

At this depth the shaking is felt, but rarely causes damage.

in line with the area average (~11 km)

For the same magnitude, a shallow earthquake is felt much more than a deep one: the energy starts closer to the surface.

What kind of quake is this?

Isolated quake

In the 30 days around this event no other quakes were recorded within 30 km: a one-off episode, very common in Italy.

How often does it happen here?

about every ~13 months

Within 50 km of this epicentre, a magnitude ≥ 3 earthquake has occurred on average this often: 11 events in the last 12 years of the INGV catalogue.

An average computed on the recent past: it tells how used this area is to shaking, not when the next quake will come — earthquakes cannot be predicted.

The closest seismic structure

Budva offshore

The epicentre lies about 11 km from Budva offshore, one of the seismic structures mapped by INGV geologists.

Faults are mapped to build better and understand the territory: knowing them says nothing about when an earthquake will occur, which remains unpredictable. Source: DISS 3.3 (INGV, CC BY 4.0).
