Hot Spots and Plate Movement Exercise
Name(s) Hot Spots and Plate Movement exercise Two good examples of present-day hot spot volcanism, as derived from mantle plumes beneath crustal plates, are Kilauea, Hawaii (on the Pacific oceanic plate) and Yellowstone (on the continental North American plate). These hot spots have produced a chain of inactive volcanic islands or seamounts on the Pacific plate (Fig. 1) and volcanic calderas or fields on the North American plate (Fig. 2) – see the figures below. Figure 1. Chain of islands and seamounts produced by the Hawaiian hot spot. Figure 2. Chain of volcanic fields produced by the Yellowstone hot spot. The purposes of this exercise are to use locations, ages, and displacements for each of these hot spot chains to determine 1. Absolute movement directions, and 2. Movement rates for both the Pacific and western North American plates, and then to use this information to determine 3. Whether the rates and directions of the movement of these two plates have been the same or different over the past 16 million years. This exercise uses the Pangaea Breakup animation, which is a KML file that runs in the standalone Google Earth application. To download the Pangaea Breakup KML file, go here: http://csmgeo.csm.jmu.edu/Geollab/Whitmeyer/geode/pangaeaBreakup /PangaeaBreakup.kml To download Google Earth for your computer, go here: https://www.google.com/earth/download/ge/agree.html Part 1.

The Track of the Yellowstone Hot Spot: Volcanism, Faulting, and Uplift
Geological Society of America Memoir 179 1992 Chapter 1 The track of the Yellowstone hot spot: Volcanism, faulting, and uplift Kenneth L. Pierce and Lisa A. Morgan US. Geological Survey, MS 913, Box 25046, Federal Center, Denver, Colorado 80225 ABSTRACT The track of the Yellowstone hot spot is represented by a systematic northeast-trending linear belt of silicic, caldera-forming volcanism that arrived at Yel- lowstone 2 Ma, was near American Falls, Idaho about 10 Ma, and started about 16 Ma near the Nevada-Oregon-Idaho border. From 16 to 10 Ma, particularly 16 to 14 Ma, volcanism was widely dispersed around the inferred hot-spot track in a region that now forms a moderately high volcanic plateau. From 10 to 2 Ma, silicic volcanism migrated N54OE toward Yellowstone at about 3 cm/year, leaving in its wake the topographic and structural depression of the eastern Snake River Plain (SRP). This <lo-Ma hot-spot track has the same rate and direction as that predicted by motion of the North American plate over a thermal plume fixed in the mantle. The eastern SRP is a linear, mountain- bounded, 90-km-wide trench almost entirely(?) floored by calderas that are thinly cov- ered by basalt flows. The current hot-spot position at Yellowstone is spatially related to active faulting and uplift. Basin-and-range faults in the Yellowstone-SRP region are classified into six types based on both recency of offset and height of the associated bedrock escarpment. The distribution of these fault types permits definition of three adjoining belts of faults and a pattern of waxing, culminating, and waning fault activity. -

Educators Guide
EDUCATORS GUIDE 02 | Supervolcanoes Volcanism is one of the most creative and destructive processes on our planet. It can build huge mountain ranges, create islands rising from the ocean, and produce some of the most fertile soil on the planet. It can also destroy forests, obliterate buildings, and cause mass extinctions on a global scale. To understand volcanoes one must first understand the theory of plate tectonics. Plate tectonics, while generally accepted by the geologic community, is a relatively new theory devised in the late 1960’s. Plate tectonics and seafloor spreading are what geologists use to interpret the features and movements of Earth’s surface. According to plate tectonics, Earth’s surface, or crust, is made up of a patchwork of about a dozen large plates and many smaller plates that move relative to one another at speeds ranging from less than one to ten centimeters per year. These plates can move away from each other, collide into each other, slide past each other, or even be forced beneath each other. These “subduction zones” are generally where the most earthquakes and volcanoes occur.

Q: Hemingway fans who’ve seen you present on his depiction in comics in Oak Park and Key West know you’ve been collecting his cameos in the form for a while. How did the book itself come about? A: Sometimes you choose the project, sometimes the project chooses you. Hemingway in Comics was the latter. It all started when I was doing articles in support of my book Hidden Hemingway, co-authored with Mark Cirino and Aaron Vetch. While I was on tour for that book, I spotted an odd comic book page framed on the wall of Hemingway’s home in Key West. It featured Donald Duck with a Disney-fied Hemingway outside Sloppy With the publication of Hemingway in Joe’s Bar. The panels appeared to be in Comics, pop-culture scholar Robert K.
