Update 20:07 UTC: The earthquake epicenter is located in the area of the Gorda Escarpment
The Mendocino Fracture Zone is a fracture zone and transform boundary off the coast of Cape Mendocino in far northern California. It runs westward from a triple junction with the San Andreas Fault and the Cascadia subduction zone to the southern end of the Gorda Ridge. It continues on west of its junction with the Gorda Ridge, as an inactive remnant section which extends for several hundred miles.
Technically, a fracture zone is not a transform fault, but in the case of the Mendocino, the term has been loosely applied to the active fault segment east of the Gorda Ridge as well as to the true fracture zone segment west of it. Many seismologists refer to the active segment as the Mendocino Fault or Mendocino fault zone.

Strong earthquake swarm in south Iceland yesterday (20-October-2017) – minor damage reported
Posted on October 21, 2017 by Jón Frímann
Yesterday (20-October-2017) a strong earthquake swarm happened in south Iceland on the SISZ fault zone. This earthquake swarm is currently ongoing and stronger earthquakes cannot be ruled out at this point.


Largest earthquake that has happened so far had the magnitude of 4,1 and four magnitude 2,9 earthquakes have happened at the writing of this article. During the strongest earthquake yesterday some minor damage has been reported, items falling out of shelves and breaking, picture frames getting skewed on walls. For a short time the village of Stokkseyri lost all line phone communication, I don’t know how long that outage lasted but phone service was restored quickly according to the news on Rúv. Largest earthquake was felt over a wide area, all the way to Reykjavík and up to Akranes village and east to Hella village.


I don’t know if this earthquake activity signals a new period of earthquake swarm in SISZ. I have listed large history of earthquakes of the SISZ in a article from 2011 here.
