Of course all volcanoes will explode, as this is going to be a very severe pole shift. What about the months and years preceding the pole shift? It is no secret that Mammoth Lake and the caldera of Yellowstone are warming up, and the populace has been prepared for these occurrences by the movie Volcano where there, in the middle of LA, lava is bubbling up. In fact, there is a fault line running from the approximate San Diego/LA area, up into the Sierras, and this is liable to rupture rather violently during one of the quakes that precedes the pole shift by some months. Volcanic eruptions from that area in the Sierras can be expected. Will Mount St. Helen erupt? All volcanoes that have been active within the memory of man will begin spewing and burping and oozing, and many that were not expected to become active will reactive. How long will it take the volcanoes to settle down? 100 years, but in a reducing ratio, over this time. By the end of 100 years, their activity will seem as today. Nevertheless, for those downwind, this post shift burping is virtually a death sentence!

Earthquakes and volcanoes share, and also do not share, causes. Common causes of quakes and eruptions are pressures upon plates to move, which causes, in addition to the plate scrapping and crunching along the edges, lava surges. Volcanoes erupt because the lava just beneath the volcano is trapped, under pressure, and the point of least resistance is an opening. Where volcanoes perpetually ooze, this is such a pressure situation, without abrupt pressure changes. In Hawaii, where volcanoes perpetually ooze, there are layers of rock, more plates overlapping, than mankind assumes. These plates are being pushed up, but other Pacific plates subducting under Hawaii, so the lava has many places to go other than up. It can move sideways, and the oozing is only one outlet, so no eruptions. Where a volcano is associated with plate crunching, such as Popo in Mexico, eruptions occur and are closely associated with quakes. Here the eruption does not settle down until the trapped lava, under pressure, has the pressure reduced. During the shift, when all volcanoes both active and inactive will erupt or ooze dramatically, there is more than plate movement and pressure involved. The core of the Earth is roiling then, in motion and continuing in motion even after the crust has stopped. Thus, volcanoes have pressure not only from trapped lava, they have it from lava surges from the core itself.

We have stated that all volcanoes active within the last 10,000 years can be considered candidates to blow, or ooze during the shift. During every pole shift, there
are places on Earth where the earth is stretched, like the Atlantic, such that mountain ranges such as the Appalachians have not experienced mountain building and
scarcely any rock outcropping are bare. Places like the Himalayas are subducting, so that rock layers are being laid under one another, and protection from the
lava occurs. Hawaii, likewise, is expected to do better than one would think, because the compression of the Pacific will layer rock strata and protect the oozing
volcanoes from roiling lava. In New Zealand, where that edge of the plate will tip up, it will be some protection from exploding volcanoes as the pressure will be
relieved. Likewise, where there is a stretch, as Iceland will experience, there will be continued oozing, but explosions caused by lava under pressure unlikely to
Inland cauldera, like Yellowstone, have their basis in pressure that has a long route to climb before heating the surface. During the shift, the fact that they are and have been an outlet for pressure competes with what is occurring in the rock strata. What comes first, for Yellowstone, will not be the rock strata thickening, as during the start of the shift the Atlantic is stretched, the plates on the move, and the core roiling. Thus, there will be explosions, though not violent, of lava, from volcanoes however active along the Sierras and Andes. The later part of the hour sees rock strata pushed under the West Coast of the Americas, shutting off access of lava from those volcanoes, which should speed the easing but not prevent the explosion in the first place. In areas under stretch in Europe and the Middle East, likewise, the roiling will cause oozing and where volcanoes are already open to the air, an outlet established, such as in Italy, they will continue during the early part of the shift to explode and ooze. One must, thus, analyze the past of local volcanoes or caulderas, to gauge their actions during the shift.
