Regional Paleogeographic Views of Earth History
This site presents a series of paleogeographic and plate-tectonic reconstructions that illustrate the broad patterns of the Earth's structural history. Reconstructions of North America, Colorado Plateau, SW North America, and Mesozoic terrane accretion. Older Mediterranean, Central and Southern Asia views are also available. Reconstructions by geologist Ron Blakey (formerly Northern Arizona University) and Colorado Plateau Geosystems, Inc.
IRIS: Seismic Monitor
This web site provides an interactive map of global seismic activity that is updated every 30 minutes. The site uses data from the National Earthquake Information Center to produce a world map with clickable areas of seismic activity. Users can click on geographical areas of the map, and will be taken to a table which describes the time, location, magnitude and comments about particular seismic events. Information is kept for earthquakes that have occurred in the last 24 hours, 15 days, and five years. For earthquakes of a magnitude of 6.0 and over, links are provided to special information pages that try to explain the where, how and why that particular event occurred. The user can also view the ground motion associated with an event and visit seismology laboratories around the world.
USGS Photo Library Archive
This collection consists of thousands of photos dating from 1868 to the present with emphasis on geology, earthquake damage, and national parks and monuments. Pioneer photographers such as W.H. Jackson, J.K. Hillers, T.H. O'Sullivan, A.J. Russell and others are featured in one section. Other topics include the Mount St. Helens volcanic eruption of 1980, and mines, mills and quarries. The system allows searching from a list of subjects, as well as a free form search. All photos are available in 100, 700 and 1400 dots per inch resolution.
Tectonic Evolution of Western North America
This narrative set of cartoons illustrate a hypothesized sequence of events in Western North America's recent geologic history beginning at 30 Ma. Each cartoon is accompanied by explanatory text to help users understand what activity is being depicted and how each one differs from the one(s) before.
Temporal evolution of the Farallon slab
Figure 1 from "Reconstructing Farallon Plate Subduction Beneath North America Back to the Late Cretaceous" by Liu et al, published in Science [2008, 322(5903), 934]. This figure shows the hypothesized temporal evolution of the Farallon slab from 100 Ma to present.
This page discusses thermal convection as it applies to the Earth's mantle and includes three QuickTime movies for three different cases of convection: heating from below, heating from within, and a combination of the two.
