5.1 quake 1 Nov 3:52 pm (GMT -6)
Just 14 minutes ago, a 5.1-magnitude earthquake struck near Escuintla, Municipio de Escuintla, Departamento de Escuintla, Guatemala. The tremor was recorded early afternoon on Wednesday, November 1st, 2023, at 3:52 pm local time, at a shallow depth of 10 km below the surface.
The event was filed by the German Research Centre for Geosciences (GFZ), the first seismological agency to report it.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 5.1 earthquake as well.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In San Jose (pop. 18,700) located 34 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in La Gomera (pop. 24,000) located 57 km from the epicenter, Escuintla (pop. 103,200) 76 km away, Santa Lucia Cotzumalguapa (pop. 62,100) 83 km away, Palin (pop. 31,300) 88 km away, Cuilapa (pop. 16,500) 92 km away, Amatitlan (pop. 71,800) 97 km away, Mixco (pop. 473,100) 115 km away, and Guatemala (pop. 994,900) 118 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.

User-reports for this quake (2)

The first report about ground shaking reached us after only 6 minutes, before other agencies reported it. We received 2 reports for this quake.
User reports estimate the perceived ground shaking intensity according to the MMI (Modified Mercalli Intensity) scale.

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.

2 aftershocks for this quake

For this earthquake, 2 aftershocks have been detected so far. The strongest was a magnitude 3.2 quake that hit 13 days after the mainshock in 6.6 km (4.1 mi) distance, in 49 km south of San Jose, Departamento de Escuintla, Guatemala, on Tuesday, Nov 14, 2023 on 01:40 pm (- local time GMT -6).
The most recent aftershock occurred 17 weeks ago 49 km south of San Jose, Departamento de Escuintla, Guatemala, and had a magnitude of 2.8.

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. 13 km2 (=5 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 6 km (4 mi).

Earthquake statistics

Average number of earthquakes

Based on data from the past 10 years and our earthquake archive back to 1900, there are about 2,800 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):
  • Mag. 7 or higher: 0.02 quakes per year (or 1 quake every 62.5 years)
  • Mag. 6 or higher: 0.45 quakes per year (or 1 quake every 2.2 years)
  • Mag. 5 or higher: 3.8 quakes per year
  • Mag. 4 or higher: 59 quakes per year
  • Mag. 3 or higher: 190 quakes per year (or 15.8 quakes per month)
  • Mag. 2 or higher: 274 quakes per year (or 22.8 quakes per month)
  • Mag. 1 or higher: 277 quakes per year (or 23.1 quakes per month)
The area where this quake occurred has a very high level of seismic activity. It has had at least 2 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 60 to 65 years.
