Mount St. Helens, located in Washington State, was sleeping peacefully on the morning of May 18, 1980. However, in just a while, the mountain blew out as lava and smoke poured out of the volcano. Long dormant, Mount St. Helens was erupting.
A 5.1 earthquake had occurred near or around Mount St. Helens. This actually caused the eruption.
As the mountain erupted, it blew out a whole side of itself, as if caused by a massive bomb.
Below is a photograph taken by the USGS.
Mount St. Helens released massive amounts of ash in the air and warped the Earth's climate for years to come. Below is a USGS image of the ash distribution.
Some people in Washington State awoke to 2-5 inches of ash covering their lawns and houses.
Following the eruption, over a course of 2 months, over 10,000 seismic events occurred in the Mount St. Helens area.
Mount St. Helens also shrunk to a much smaller degree.
The Ring of Fire is the edge of the Pacific tectonic plate. On those edges, other tectonic plates rub against each other. The earth is pushed up or down. Volcanoes are formed on the edge of this Pacific Tectonic Plate.
The Ring of Fire are the volcanoes surrounding the Pacific Ocean. Below is an image of the Ring of Fire.

The red area are the edges of the tectonic plates.
Why is it called the 'Ring of Fire'?
Volcanoes produce fire and lava, and with so many volcanoes surrounding the Pacific tectonic plate in an awkward circle-like formation, it became known as the Ring of Fire.
Are these volcanoes active?
Some are very active, while others are dormant. Mount St. Helens in Washington State, US is included in this Ring of Fire.
(Note: The Earth's axis shifted 4 inches from the March 11, 2011 Earthquake and Tsunami)
So the axis shifted. Will the weather go crazy now?
No. Not at all. 4 inches compared to the Earth is incredibly small. Any changes would be unrecognizable to the human eye or experience (wind, rain, etc.)
For the weather to go crazy, the Earth has to pretty much turn upside down or shift an incredible amount more than 4 inches.
My weather seems to be different than forecasted. Is this due to the shift?
No. Meteorologists are not prophets, and likely never will be. It is expected for the temperature to be slightly different than forecasted or rain to occur even if it wasn't forecasted. Recently, Chicago had bands of heavy lake effect snow that weathermen did not forecast.
A WIDESPREAD DESTRUCTIVE TSUNAMI HAS OCCURRED, AND TSUNAMI WAVES HAVE NOW CROSSED THE ENTIRE PACIFIC. FOR ALL AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES. DUE TO LOCAL EFFECTS SOME AREAS MAY CONTINUE TO EXPERIENCE SMALL SEA LEVEL CHANGES FOR AN EXTENDED PERIOD LASTING HOURS OR EVEN DAYS.
FOR ALL AREAS COVERED BY THIS CENTER...THE TSUNAMI WARNING IS CANCELLED.
THIS WILL BE THE FINAL BULLETIN ISSUED FOR THIS EVENT UNLESS ADDITIONAL INFORMATION BECOMES AVAILABLE.
THE JAPAN METEOROLOGICAL AGENCY MAY ALSO ISSUE TSUNAMI MESSAGES FOR THIS EVENT TO COUNTRIES IN THE NORTHWEST PACIFIC AND SOUTH CHINA SEA REGION. IN CASE OF CONFLICTING INFORMATION... THE MORE CONSERVATIVE INFORMATION SHOULD BE USED FOR SAFETY.
THE WEST COAST/ALASKA TSUNAMI WARNING CENTER WILL ISSUE PRODUCTS FOR ALASKA...BRITISH COLUMBIA...WASHINGTON...OREGON...CALIFORNIA.
LAT - LATITUDE (N-NORTH, S-SOUTH) LON - LONGITUDE (E-EAST, W-WEST) TIME - TIME OF THE MEASUREMENT (Z IS UTC IS GREENWICH TIME) AMPL - TSUNAMI AMPLITUDE MEASURED RELATIVE TO NORMAL SEA LEVEL. IT IS ...NOT... CREST-TO-TROUGH WAVE HEIGHT. VALUES ARE GIVEN IN BOTH METERS(M) AND FEET(FT). PER - PERIOD OF TIME IN MINUTES(MIN) FROM ONE WAVE TO THE NEXT.
NOTE - DART MEASUREMENTS ARE FROM THE DEEP OCEAN AND THEY ARE GENERALLY MUCH SMALLER THAN WOULD BE COASTAL MEASUREMENTS AT SIMILAR LOCATIONS.
