quote:5/22/2015 — Whole West coast moved over 48 hours — Oregon Earthquake near Erupting Volcano
Over the past 48 hours the whole of the West coast of the United States has moved on at least a 4.0 magnitude level or greater.
This new West coast earthquake activity is expected, but unwelcome.
See the earthquake forecast for the West coast of the United States here (issued May 21 2015):
This new West coast earthquake unrest began with a 4.2M at the border of Alaska and British Colombia Canada (as expected).
The Alaska activity was shortly followed by a new swarm of earthquakes at the Salton Sea Volcanic buttes (located in Southern California).
The Southern California volcanic earthquake swarm was shortly followed by a 4.1M event in Napa Vallay / Gorda Escarpment zone near San Francisco, CA.
All the aforementioned activity has now been followed by a 4.2 magnitude earthquake off the shores of Oregon. These events all point towards Vancouver Island BC as a “silent zone” to watch, along with Washington State.
Worthy to note, this Oregon earthquake occurred very close to the location of a new underwater volcano which was detected along the Axial Seamount, which is located due West of the Oregon Coast.
A rather overwhelming review of recent earthquakes and past and present volcanic activity.
The author is not a seismologist as far as I can see, but certainly has an (obsessive?) interest in the field.
When he says things like (paraphrased) "you won't see this reported in the media" or "the professionals won't tell you about the link of quakes to inactive volcanoes" my reaction is quack conspiracy thinking ... but what is the conspiracy?
Just from your quotes it smells very quacky to me. ...
Or one level down to "alarmist" ...
The evidence he cites should be confirmable, however, and he provides some links in that regard - to recent earthquakes.
His predictions seem somewhat in line with typical seismologists saying that we don't know where or when with any degree of confidence, but that dormant sections of otherwise active faults are likely to see some activity as stress builds up.
It seems that he has produced quite a large model of past quakes by time, location and depth, and that he has correlated it with continental plates.
There has been increased quake activity on the west coast the last two days. Nothing above 4.1 as I see. Mag 4 tremblers are not unusual in California.
As I remember the Richter Scale is logarithmic and each integer represents a 10-fold change in energy. Checking with wiki I see:

Magnetude
Average Quake Effects
3.0–3.9
Often felt by people, but very rarely causes damage. Shaking of indoor objects can be noticeable.
4.0–4.9
Noticeable shaking of indoor objects and rattling noises. Felt by most people in the affected area. Slightly felt outside. Generally causes none to minimal damage. Moderate to significant damage very unlikely. Some objects may fall off shelves or be knocked over.
5.0–5.9
Can cause damage of varying severity to poorly constructed buildings. At most, none to slight damage to all other buildings. Felt by everyone.
So lots of little quakes in the 3.0–3.9 are just noticeable but rarely cause damage, and even quakes in the 4.0–4.9 range rarely cause significant damage (depending on what things on shelves that fall off involve), and it is only when you get into the 5.0–5.9 range that you begin to get significant damage ... to poorly constructed structures.
This is what I was talking about it being an "alarmist" site rather than a conspiracy theory site (although it seems the author is willing to take that path), as he talks about pending quakes as posing a great danger yet most of the quakes he documents are under 4.5, and he makes it seem more dangerous than it is.
Nor should we be surprised by any links between quakes and volcanic activity as this link is very well documented along plate boundaries.
That being said, I found the global scale that he documented quite fascinating -- the earth is indeed in a rather constant state of flux and change, and if nothing else this is one way to show that fact.
I've only experienced one quake, while camping in California, and we didn't know what it was until we left in the morning and went to lunch. It was in the 3's as I recall.

A series of four earthquakes struck late Sunday and Monday morning off the coast of Oregon.
It started with a 5.8 earthquake at 11:52 p.m. in the Pacific nearly 300 miles west of Newport.
The Lincoln County Sheriff's office in Newport said it did not receive any calls from the public about the quake.
Amy Vaughan with the United States Geological Survey (USGS) said it occurred in an active seismic area.
The second earthquake, 4.3 magnitude, struck just after midnight just a mile away from the first quake.
The third earthquake hit just before 4 a.m. Monday about 278 miles northwest of Coos Bay. It measured 5.5 magnitude.
The fourth earthquake was reported at 7:46 a.m. near the same area. It measured 4.4 magnitude.
There was no tsunami threat from any of the quakes.
His "prediction" was for activity further north, and this looks like it is connected to the same seamount where he had already recorded activiety ... a bit bigger ...
