Karl W. Luckert--"Four Theories of Earth Expansion and the Eocene Tectonic Event"--Urbino-2004www.youtube.com/watch?v=KV86BXJrBI0youtu.be/KV86BXJrBI0This presentation is pretty slow - but packed full of interesting evidence A comparison of four different theories shed a lot of light on the fact of an expanding earth Problems with these theoriesNone of them offer any indication of MECHANISM only J. Marvin Herndon's theory of Whole Earth Decompression Dynamics (WEDD) give the mechanism that drives it all At issue with what the presenter says about Scota Plate and the The Sandwich Island rift This presenter makes the claim that Antarctica crashed into South America and drug part of it to the East - Suggesting that The South Sandwich Plate is actually / was actually the Southern most tip of South America On the contrary - FD-WEDD suggest: That the South Sandwich Plate is actually the Volcanic front of the Pacific spread into the Atlantic The eastern edge of the South Sandwich Plate is a ring of volcanoes - sitting directly above the Pacific Rift and the Atlantic Rift. To me - this is evidence that the Atlantic expansion slowed to a halt while the Pacific continued to expand and spill over into the Atlantic and on top of the the rift zone

An Elusive Volcano: Mount Michael – South Sandwich Islands volcanohotspot.wordpress.com/2015/10/15/an-elusive-volcano-mount-michael-south-sandwich-islands/In the South Sandwich Islands now, there are 9 volcanoes that need watching… and one of them is Mount Michael on Sounders Island. ... The South Sandwich volcanic arc system is the product of the subduction (westwards) of the South American Plate underneath the tiny Sandwich Plate which had formed by seafloor spreading between South America and Antarctica. The Sandwich Plate is less than 8 million years old. It is one of the smallest tectonic plates and it moves to the east at about 7 cm per year. The volcanic arc on its eastern margin is younger than 5 million years. It is called the South Sandwich Islands chain. Basalts make up at least 70% of the islands, while on average, about 60% of each island consist of lava and about 40% of tephra. Eight of the eleven exhibit ongoing volcanic activity. Also, there is an active submarine vent, Protector Shoal, just 30 m below the surface. This vent erupted in 1962 and created a giant raft of floating pumice that drifted several thousand miles to reach New Zealand. ... The South Sandwich Islands are extremely active volcanically. Mt. Michael, on Saunders Island, is roughly in the middle of the island chain.
