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.

The Effects of the Cyclones of 1983 on the Atolls of the Tuamotu Archipelago (French Polynesia)
THE EFFECTS OF THE CYCLONES OF 1983 ON THE ATOLLS OF THE TUAMOTU ARCHIPELAGO (FRENCH POLYNESIA) J. F. DUPON ORSTOM (French Institute ofScientific Research for Development through cooperation), 213 Rue Lafayette - 75480 Paris Cedex 10, France Abstract. In the TUAMOTU Archipelago, tropical cyclones may contribute to the destruction as well as to some building up of the atolls. The initial occupation by the Polynesians has not increased the vulnerability of these islands as much as have various recent alterations caused by European influence and the low frequency of the cyclone hazard itself. An unusual series of five cyclones, probably related to the general thermic imbalance of the Pacific Ocean between the tropics struck the group in 1983 and demonstrated this vulnerability through the damage that they caused to the environment and to the plantations and settle ments. However, the natural rehabilitation has been faster than expected and the cyclones had a beneficial result in making obvious the need to reinforce prevention measures and the protection of human settle ments. An appraisal of how the lack of prevention measures worsened the damage is first attempted, then the rehabilitation and the various steps taken to forestall such damage are described. I. About Atolls and Cyclones: Some General Information Among the islands of the intertropical area of the Pacific Ocean, most of the low-lying lands are atolls. The greatest number of them are found in this part of the world. Most atolls are characterized by a circular string of narrow islets rising only 3 to 10 m above the average ocean level. -

Cenozoic Changes in Pacific Absolute Plate Motion A
CENOZOIC CHANGES IN PACIFIC ABSOLUTE PLATE MOTION A THESIS SUBMITTED TO THE GRADUATE DIVISION OF THE UNIVERSITY OF HAWAI`I IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN GEOLOGY AND GEOPHYSICS DECEMBER 2003 By Nile Akel Kevis Sterling Thesis Committee: Paul Wessel, Chairperson Loren Kroenke Fred Duennebier We certify that we have read this thesis and that, in our opinion, it is satisfactory in scope and quality as a thesis for the degree of Master of Science in Geology and Geophysics. THESIS COMMITTEE Chairperson ii Abstract Using the polygonal finite rotation method (PFRM) in conjunction with the hotspot- ting technique, a model of Pacific absolute plate motion (APM) from 65 Ma to the present has been created. This model is based primarily on the Hawaiian-Emperor and Louisville hotspot trails but also incorporates the Cobb, Bowie, Kodiak, Foundation, Caroline, Mar- quesas and Pitcairn hotspot trails. Using this model, distinct changes in Pacific APM have been identified at 48, 27, 23, 18, 12 and 6 Ma. These changes are reflected as kinks in the linear trends of Pacific hotspot trails. The sense of motion and timing of a number of circum-Pacific tectonic events appear to be correlated with these changes in Pacific APM. With the model and discussion presented here it is suggested that Pacific hotpots are fixed with respect to one another and with respect to the mantle. If they are moving as some paleomagnetic results suggest, they must be moving coherently in response to large-scale mantle flow. iii List of Tables 4.1 Initial hotspot locations . -

Observations of Collared Petrels (Pterodroma Brevipes) on Vanua Lava, Vanuatu, and a Review of the Species’ Breeding Distribution

Observations of collared petrels (Pterodroma brevipes) on Vanua Lava, Vanuatu, and a review of the species’ breeding distribution ALAN J.D. TENNYSON* COLIN M. MISKELLY Museum of New Zealand Te Papa Tongarewa, PO Box 467, Wellington 6140, New Zealand STEPHEN L. TOTTERMAN 179 Reedy Creek Rd., Empire Vale, NSW, 2478, Australia Abstract We report a polymorphic population of collared petrels (Pterodroma brevipes) apparently breeding on Vanua Lava, northern Vanuatu, in the austral autumn-winter. This is one of only 5 known extant colonies of the species. One of the 2 birds captured by us matched the description of the recently described dark plumaged Pt. b. magnificens which had never been reported caught ashore previously. However, the other bird caught was a paler individual indicating that the taxon is variable in plumage colour, like other Pt. brevipes populations. We suggest that the 2 other criteria used to define the subspecies Pt. b. magnificens (body size and breeding chronology) are also questionable and require further investigation.
