Regarding the Oregon quake:

Featured on Sott: 4.9 earthquake strikes off Oregon coast which links to: Earthquake swarms reported at Mt. Hood, Mt. Rainier and Mt. St. Helens: Is a major eruption imminent?

From the article:
https://www.sott.net/article/318566-Earthquake-swarms-reported-at-Mt-Hood-Mt-Rainier-and-Mt-St-Helens-Is-a-major-eruption-imminent said:
Mt. Hood

Mount Hood is located only about 50 miles away from Portland, Oregon, and it is one of the most dangerous volcanoes in America. Over the past 30 days, there have been 96 earthquakes at Mt. Hood, and most of them have been centered on the south side of the mountain. Why this is so alarming is because it was also the south side of Mt. St. Helens that violently exploded back in 1980.

Here is a map which shows the recent activity at Mt. Hood...
Mt_Hood_Today_460x240.jpg

According to Wired, the majority of the earthquakes that are happening are at a depth of between 3 and 5 kilometers, and this could be a sign that magma is ascending...

Right now, the earthquake swarm at Mt. Hood is centered just to the south of the main edifice (see below) and most of the earthquakes are between 3 and 5 kilometers below the surface. This is likely the zone where magma is being staged as it ascends from its source.



And further, according to RSOE:

Earthquake in USA on May 17 2016 03:31 AM (UTC).

Situation Update No. 2 on May 20 2016 05:08 PM (UTC)

Fears are mounting a massive volcanic eruption could be on its way after a swarm of 62 mini-earthquakes were recorded around one of American's biggest mountains. A series of tremors continued for around 24 hours. Minor tremors are common around the Mt Hood volcano, which is located near to Portland, Oregon, with around three recorded every week within a 10 kilometre radius of the volcano. But for 63 in just 24 hours is extremely rare and could be a sign that an eruption is on its way. A spate of small tremors around a volcano usually signifies that magma and gasses beneath the surface are beginning to navigate their exit. Portland State University Geology Professor Emeritus Scott Burns told KATU News: "If you get swarms under a working volcano, the working hypothesis is that magma is moving up underneath there." The tremors began on Sunday and continued into the beginning of this week. The massive volcano, which reaches a height of 3,429 metres, has experienced four major eruptions in the last 15,000 years, but three of those have come in the last 1,800 years. The last major one occurred in 1782 and erupted for almost two decades. The news follows on from a similar announcement regarding St Helens volcano in Washington, where a spate of tremors have also been felt. Professor Burns continued: "It just reminds us that we live in a geologically active area. :rolleyes: Volcanoes do occur periodically. "It may be related to an eventual eruption. If it is, we will know well in advance." Yellowstone volcano has been another US volcano which has showed signs that it is about to burst into life. Terrifying footage recently emerged which shows steam and ash rising beneath the surface of the 2,805m tall volcano, which is probably the deadliest in the US, in Wyoming, fuelling fresh concern it could be about to blow.
 
Since the connection between the sun and earthquakes has been largely introduced here, I thought that it would be interesting to share this article in this thread :

NASA’s Van Allen Probes Reveal Long-term Behavior of Earth’s Ring Current

New findings based on a year's worth of observations from NASA’s Van Allen Probes have revealed that the ring current – an electrical current carried by energetic ions that encircles our planet – behaves in a much different way than previously understood.

The ring current has long been thought to wax and wane over time, but the new observations show that this is true of only some of the particles, while other particles are present consistently. Using data gathered by the Radiation Belt Storm Probes Ion Composition Experiment, or RBSPICE, on one of the Van Allen Probes, researchers have determined that the high-energy protons in the ring current change in a completely different way from the current’s low-energy protons. Such information can help adjust our understanding and models of the ring current – which is a key part of the space environment around Earth that can affect our satellites.

The findings were published in Geophysical Research Letters.

During periods when there are no geomagnetic storms affecting the area around Earth (left image), high-energy protons (with energy of hundreds of thousands of electronvolts, or keV; shown here in orange) carry a substantial electrical current that encircles the planet, also known as the ring current. During periods when geomagnetic storms affect Earth (right), new low-energy protons (with energy of tens of thousands of electronvolts, or keV; shown here in magenta) enter the near-Earth region, enhancing the pre-existing ring current.

“We study the ring current because, for one thing, it drives a global system of electrical currents both in space and on Earth’s surface, which during intense geomagnetic storms can cause severe damages to our technological systems," said lead author of the study Matina Gkioulidou, a space physicist at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. “It also modifies the magnetic field in near-Earth space, which in turn controls the motion of the radiation belt particles that surround our planet. That means that understanding the dynamics of the ring current really matters in helping us understand how radiation belts evolve as well.”

The ring current lies at a distance of approximately 6,200 to 37,000 miles (10,000 to 60,000 km) from Earth. The ring current was hypothesized in the early 20th century to explain observed global decreases in the Earth’s surface magnetic field, which can be measured by ground magnetometers. Such changes of the ground magnetic field are described by what's called the Sym-H index.

“Previously, the state of the ring current had been inferred from the variations of the Sym-H index, but as it turns out, those variations represent the dynamics of only the low-energy protons,” said Gkioulidou. “When we looked at the high-energy proton data from the RBSPICE instrument, however, we saw that they were behaving in a very different way, and the two populations told very different stories about the ring current.”

The Van Allen Probes, launched in 2012, offer scientists the first chance in recent history to continuously monitor the ring current with instruments that can observe ions with an extremely wide range of energies. The RBSPICE instrument has captured detailed data of all types of these energetic ions for several years. “We needed to have an instrument that measures the broad energy range of the particles that carry the ring current, within the ring current itself, for a long period of time,” Gkioulidou said. A period of one year from one of the probes was used for the team’s research.

“After looking at one year of continuous ion data it became clear to us that there is a substantial, persistent ring current around the Earth even during non-storm times, which is carried by high-energy protons. During geomagnetic storms, the enhancement of the ring current is due to new, low-energy protons entering the near-Earth region. So trying to predict the storm-time ring current enhancement while ignoring the substantial pre-existing current is like trying to describe an elephant after seeing only its feet,” Gkioulidou said.

The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, built and operates the Van Allen Probes for NASA's Science Mission Directorate. RBSPICE is operated by the New Jersey Institute of Technology in Newark, New Jersey. The mission is the second mission in NASA's Living With a Star program, managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland.

This enhancement of the electrical current disrupt in some ways the magnetic field and may produce a downward of relatively charged particule in the atmosphere by some mechanisms ( like magnetotail reconnections : https://www.sott.net/article/318378-Magnetic-explosions-observed-by-NASA-spacecraft-for-first-time).
Hence, it increases the electric vertical gradient in the atmosphere which may engender atmospheric or geological phenomenas of compensation.

For the geological point of view, we have the piezoelectricity that Pierre highlighted in his book and Ben Davidson from Suspicious observer from his research.
For the atmosheric one, Gerald Pollack pointed out an interesting hypothesis about 'a fourth state of the water' and the electric current that could be produce by the dissociation of water in two differents charged states by the sun's radiation :

In previous conference talks starting from the first EU2012, Dr. Jerry Pollack has shown that water contains a fourth phase, which bears negative charge. When water evaporates, that fourth phase rises in the form of negatively charged aerosol droplets, while positive charge rises in the form of hydronium ions. The negative-positive combination may condense into clouds. In sunshine, the evaporated hydronium ions build high into the atmosphere, while at nighttime they hardly build at all; hence, horizontal charge gradients form at the day-night boundaries. Jerry will suggest that those charge gradients drive wind flow and, more generally, may be the cause of terrestrial winds; in addition, he theorizes that that the same forces acting to produce persistent winds may help to maintain the spin of the earth on its axis.

Dr. Gerald Pollack is a professor and a lab director in the bio-engineering department of the University of Washington, Seattle. He has spent over 10 years researching the role of water in biological tissue. He is the author of the popular book The Fourth Phase of Water, www.ebnerandsons.com.
