In a revisit to my article" 8.9 Quake Sets earthquake Domino Effect In Motion" in which I present the evidence that a single quake of large magnitude will set off other large quakes and volcano eruptions shortly after the initial event. Many earthquakes above magnitude 6.0 have occurred in the world and volcano eruptions have also happened since the now upgraded to 9.0 Japan quake struck Honshu Island 3/11/1.

Within hours two volcanoes erupted in Kamchatka, Russia, one in Indonesia, Shinmoedake volcano resumed eruption after a brief quiet period.

The following is a list of quakes, which have occurred in the world since the 9.0 on 4/11/2011.

• Magnitude 6.6 EASTERN HONSHU, JAPAN April 11, 2011
• Magnitude 7.1 NEAR THE EAST COAST OF HONSHU, JAPAN April 07, 2011
• Magnitude 6.5 VERACRUZ, MEXICO April 07, 2011
• Magnitude 6.7 SOUTH OF JAVA, INDONESIA April 03, 2011
• Magnitude 6.8 MYANMAR March 24, 2011
• Magnitude 6.6 OFF THE EAST COAST OF HONSHU, JAPAN March 22, 2011
• Magnitude 6.3 VANUATU March 17, 2011
• Magnitude 9.0 NEAR THE EAST COAST OF HONSHU, JAPAN March 11, 2011

More importantly, what earthquake activity occurred in the world before the Japanese quake?   

• Magnitude 5.4 MYANMAR-CHINA BORDER REGION March 10, 2011
• Magnitude 6.5 NEW BRITAIN REGION, PAPUA NEW GUINEA March 09, 2011
• Magnitude 7.2 NEAR THE EAST COAST OF HONSHU, JAPAN March 09, 2011
• Magnitude 6.6 SOLOMON ISLANDS March 07, 2011
• Magnitude 6.5 SOUTH SANDWICH ISLANDS REGION March 06, 2011
• Magnitude 6.3 SOUTH ISLAND OF NEW ZEALAND February 21, 
• Magnitude 6.6 OFFSHORE MAULE, CHILE February 14, 2011
• Magnitude 6.8 OFFSHORE BIO-BIO, CHILE February 11, 2011
• Magnitude 6.5 CELEBES SEA February 10, 2011
• Magnitude 7.2 SOUTHWESTERN PAKISTAN January 18, 2011
• Magnitude 7.0 LOYALTY ISLANDS January 13, 2011
• Magnitude 6.6 VANUATU January 09, 2011

What the big picture reveals here is a very active western Pacific Rim of Fire from off the coast of Russia southward to around a thousand miles off the coast of Southern Australia. What we have here is adjustments being made to this day in the Earth's fault system in the western Pacific from the 9.1 Indonesia quake of 12/26/2004. The pressure put on the whole Pacific Rim of Fire fault system from the 2004 Indonesia quake is also responsible for the 8.8 quake in Chile, 2010.

The estimated fault movement from the 9.0 Japanese quake is a fracture of 150 miles long and 50 miles wide. The same massive movement only on a grander scale was made by the 9.1 Indonesia quake. Such great Earth displacement made in a matter of seconds puts pressure on the whole fault system worldwide, resulting in either several significant earthquakes of magnitude 7.5 and below occurring in different parts of the world or another monumental event of magnitude 8.5 or above occurring, perhaps across the planet.

The worldwide shock wave created by such strong quakes also has an effect on all fault systems, especially those where the slightest movement will set off a rupture.

Fault systems are basically cracks from stress in the Earth's crust. When an area has significant movement, the stress from this displacement must be rectified in the form of rupturing elsewhere in the form of an earthquake.

Volcano eruptions happening in connection with significant quakes are the result of magma being forced to the surface from the added stress. Most volcano eruptions act as stress relievers rather than adding to it. The release of magma takes the place of significant plate rupture as it is pushed to the surface.

Judging from the scenario, we are currently in, since the Indonesia quake we have around ten years to go before the Earth settles down from such monumental plate displacements.

We may have been lucky in escaping yet another magnitude quake of above 8.0 but the consensus isn’t in yet.
