Mag. 4.3 earthquake - 23 mi west of Everett, Snohomish County, Washington, USA, on Sunday, Oct 8, 2023, at 07:21 pm (Los Angeles time) -

A moderate magnitude 4.3 earthquake occurred under the sea near the coast of Washington,  United States, in the late afternoon of Sunday, Oct 8, 2023 at 7.21 pm local time (America/Los Angeles GMT -7). The quake had a shallow depth of 57 km (36 mi) and was felt widely in the area. The shallow depth of the quake caused it to be felt more strongly near the epicenter than a deeper quake of similar magnitude would.

Moderate magnitude 4.5 earthquake 24 miles west of Everett, Washington, United States

4.5 quake 8 Oct 7:21 pm (GMT -7)
4.5 quake 8 Oct 7:21 pm (GMT -7)
An earthquake of magnitude 4.5 occurred early evening on Sunday, October 8th, 2023, at 7:21 pm local time near Everett, Snohomish County, Washington, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a moderately shallow depth of 35 miles. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from The Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 4.5 as well. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 4.5.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Port Townsend (pop. 9,300) located 7 miles from the epicenter, and Oak Harbor (pop. 22,700) 19 miles away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Edmonds (pop. 41,400) located 22 miles from the epicenter, Lynnwood (pop. 37,000) 23 miles away, Everett (pop. 108,000) 24 miles away, Marysville (pop. 66,800) 25 miles away, Shoreline (pop. 55,400) 26 miles away, Bothell (pop. 42,900) 30 miles away, Seattle (pop. 684,500) 34 miles away, and Bellevue (pop. 139,800) 37 miles away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.

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.

Aftershocks for this quake

No aftershocks have been recorded so far. When aftershocks are detected, we will update this section.

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. 2 km2 (=1 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 2 km (2 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 6,500 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):
  • Mag. 6 or higher: 0.03 quakes per year (or 1 quake every 31.3 years)
  • Mag. 5 or higher: 0.11 quakes per year (or 1 quake every 9.4 years)
  • Mag. 4 or higher: 0.72 quakes per year (or 1 quake every 1.4 years)
  • Mag. 3 or higher: 6.7 quakes per year
  • Mag. 2 or higher: 70 quakes per year
  • Mag. 1 or higher: 433 quakes per year (or 36.1 quakes per month)
The area where this quake occurred has a moderate level of seismic activity. However, It has had at least 4 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 30 to 35 years.

Strongest in 4 years

The earthquake was the strongest to hit this part of the  United States in over 4 years. Earlier, the last quake of equal or greater strength near the present epicenter had been a magnitude 4.6 earthquake on Friday, Jul 12, 2019, at 02:51 am local time (America/Los Angeles GMT -7) in 54 km (33 mi) distance to the east:

The strongest-ever (since 1900) recorded quake in this area measured magnitude 7.3. It had occurred 78 years ago earlier, on Sunday, Jun 23, 1946, at 10:13 am local time (America/Vancouver GMT -7) in British Columbia,  Canada:




Below is a list and map of (larger or recent) quakes that had occurred near the area of the epicenter before this earthquake (within up to 100 km/61 mi distance, up to 300 km/183 mi for very large quakes above mag. 7). Filter the list to limit the number to show, by magnitude or time before.
