Earth Changes: The Moving Earth 

Earthquakes, Volcanoes and Tectonic Plate Movement,  Massive Tsunami's are all interrelated. 

According to The United States Geological Survey website, there are no more significant earthquakes (7.0 or greater) than in the past and that the amount has remained fairly constant. They claim the the ability to monitor quakes has improved making them appear to be on the increase due to the increase of Monitoring stations. Over a 33 year period, the USGS states The number of Great earthquakes during this period was about at the level indicated by the long-term average, with 27 events in 33 years.

The earths features have changed over a period of millions of years. Mankind has come to a conclusion that various species, possibly whole civilizations have vanished with a catastrophic natural disaster. It possible that it will be by a super volcanic event. It is possible that the earth poles could shift (at least in theory), in a matter of days, no thousands of years and a wall of water could cover the entire surface of the earth. Our how about a super heated explosion from an underground  volcanic cauldera, which erupts with such fury that all of the The USA is vaporized with such heat. then endure blackness (if anyone survives) due to dust an dirt floating in the atmosphere, for YEARS. The experience would be something akin to a major nuclear blast! 

Below you'll find various scientific data concurring that such events HAVE HAPPENED before. Will they happen again? Most likely -- we can only hope they will not happen within our human species lifetimes.

The October 17, 1989 Loma Prieta, California Earthquake

AnOn October 17, 1989, at 5:04:15 p.m A magnitude 6.9 (moment magnitude; surface-wave magnitude, 7.1) earthquake severely shook the San Francisco and Monterey Bay regions. The epicenter was located at 37.04 N. latitude, 121.88 W. longitude near Loma Prieta peak in the Santa Cruz Mountains, approximately 14 km (9 mi) northeast of Santa Cruz and 96 km (60 mi) south-southeast of San Francisco. The earthquake occurred when the crustal rocks comprising the Pacific and North American Plates abruptly slipped as much as 2 meters (7 ft) along their common boundary-the San Andreas fault system. The rupture initiated at a depth of 18 km (11 mi) and extended 35 km (22 mi) along the fault, but it did not break the surface of the Earth .

San Francisco 1906 Quake - 

The California earthquake of April 18, 1906 ranks as one of the most significant earthquakes of all time. Today, its importance comes more from the wealth of scientific knowledge derived from it than from its sheer size. Rupturing the northernmost 430 kilometers of the San Andreas fault from northwest of San Juan Bautista to the triple junction at Cape Mendocino, the earthquake confounded contemporary geologists with its large, horizontal displacements and great rupture length. Indeed, the significance of the fault and recognition of its large cumulative offset would not be fully appreciated until the advent of plate tectonics more than half a century later. Analysis of the 1906 displacements and strain in the surrounding crust led Reid (1910) to formulate his elastic-rebound theory of the earthquake source, which remains today the principal model of the earthquake cycle.

 At almost precisely 5:12 a.m., local time, a foreshock occurred with sufficient force to be felt widely throughout the San Francisco Bay area. The great earthquake broke loose some 20 to 25 seconds later, with an epicenter near San Francisco. Violent shocks punctuated the strong shaking which lasted some 45 to 60 seconds. The earthquake was felt from southern Oregon to south of Los Angeles and inland as far as central Nevada. The highest Modified Mercalli Intensities (MMI's) of VII to IX paralleled the length of the rupture, extending as far as 80 kilometers inland from the fault trace. One important characteristic of the shaking intensity noted in Lawson's (1908) report was the clear correlation of intensity with underlying geologic conditions. Areas situated in sediment-filled valleys sustained stronger shaking than nearby bedrock sites, and the strongest shaking occurred in areas where ground reclaimed from San Francisco Bay failed in the earthquake. Modern seismic-zonation practice accounts for the differences in seismic hazard posed by varying geologic conditions.
