How frequent are earthquakes in the area near the epicenter of this quake (within 100 km/61 mi)?

Q: How frequent are earthquakes in the area near the epicenter of this quake (within 100 km/61 mi)?

The area where this quake occurred has a very high level of seismic activity. Based on data from the past 14 years and our earthquake archive back to 1900, there are about 62 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi). It has had at least 15 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.

Nearby places

The closest larger town where the quake might have been felt is Santo, a town with 13,000 inhabitants in Vanuatu, in 74 km (46 mi) distance south of the epicenter. People likely experienced moderate shaking there. Several smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking. In the capital of

Vanuatu, Port Vila, 345 km (214 mi) away from the epicenter, the earthquake was probably felt as light shaking.

What is Intensity and the Mercalli Intensity Scale?

The amount of shaking that occurs on the surface due to an earthquake is called the intensity. It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.
Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.

4 aftershocks for this quake

For this strong earthquake, 4 aftershocks have been detected so far. The strongest was a magnitude 5.6 quake that hit 8 weeks after the mainshock in 41 km (25 mi) distance, in Vanuatu Islands on Thursday, Oct 14, 2021 on 04:51 pm (Efate local time GMT +11).
The most recent aftershock occurred 3 years ago 42 Km NE of Luganville, Vanuatu, and had a magnitude of 4.5.

What are aftershocks?

Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.

[More info]

What about this quake?

Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface of approx. 794 km² (=307 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 49 km (30 mi).

Earthquake statistics

Average number of earthquakes

Based on data from the past 14 years and our earthquake archive back to 1900, there are about 62 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):

Mag. 7 or higher: 0.12 quakes per year (or 1 quake every 8.3 years)
Mag. 6 or higher: 0.72 quakes per year (or 1 quake every 1.4 years)
Mag. 5 or higher: 14.2 quakes per year
Mag. 4 or higher: 60 quakes per year (or 5 quakes per month)
Mag. 3 or higher: 61 quakes per year (or 5.1 quakes per month)
Mag. 2 or higher: 61 quakes per year (or 5.1 quakes per month)

The area where this quake occurred has a very high level of seismic activity. It has had at least 15 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.
