Differently from the common wind waves, tsunamis are characterized by large wavelengths (ranging from tens to hundreds of km) and long periods (ranging from minutes to hours). Several natural phenomena such as earthquakes, landslides, volcanic eruptions, the rapid change of atmospheric pressure (meteotsunami), or asteroids impacts can be the source of a tsunami; among these, the most frequent is represented by the earthquakes. Most of the very tsunamigenic earthquakes occur nearby the Earth convergent boundaries (Fig.

    Rhiana Elizabeth Henry Tectonic History Hildebrand Project 1A December 9th, 2016 North America subducted under Rubia Are there modern analogs for Hildebrand’s model of North America subducting under Rubia? In the Geological Society of America Special Papers “Did Westward Subduction Cause Cretaceous–Tertiary Orogeny in the North American Cordillera?” and “Mesozoic Assembly of the North American Cordillera” by Robert S. Hildebrand, the author argues that the North American continent experienced westward subduction under what he calls a “ribbon continent” known as Rubia around ~124Ma. This ribbon continent is composed of multiple terranes both known to be exotic to North America, and terranes that were previously thought to be part of North America. As the seaway between Rubia and North America closed, Hildebrand postulates that North America was dragged underneath with the oceanic crust. This continental material combined with the fluids from the margin caused great amounts of magmatism in the North American Cordillera. Eventually the continental crust broke due to upward buoyancy. This caused slab failure around 75-60 Ma, followed by a reversal of subduction polarity around 53 Ma, with eastward subduction through the mid- Tertiary (Fig. 1). As a way of checking to see if this hypothesis is plausible, I investigated modern geologic settings that are undergoing similar tectonic events. Although these regions are Figure 1: Hildebrand’s model of subduction of not perfect analogies, they share enough North America and Rubia. From Hildebrand, 2009. 1 Rhiana Elizabeth Henry Tectonic History Hildebrand Project 1A December 9th, 2016 tectonic features that Hildebrand’s model appears somewhat less outlandish.

Received 18 February 2013, revised 22 November 2013, accepted 11 May 2015 ABSTRACT Running along the middle of the Philippine archipelago from south to north, the Philippine fault zone is one of the world’s major strike-slip faults. Intense volcanism in the archipelago is attributed to the ongoing subduction along the trench systems surrounding it. This study interprets the magnetic data covering the Philippine fault zone and the bounding archi- pelago subduction systems to understand the structural characteristics of the study area. Magnetic data analysis suggests that the Philippine fault is roughly distributed along the boundary of high/low magnetization and separates the different amplitude features of the first order analytic signal. Visayas province is a specific area bounded by the other parts of the Philippine ar- chipelago. Further differentiating the tectonic units, the proto-Southeast Bohol Trench should be the main tectonic boundary between Visayas and Mindanao. A clear NE - SW boundary separates Luzon from Visayas as shown by the variant depths to the top of the magnetic basement. This boundary could suggest the different tectonic characteristics of the two regions. Key words: Philippine fault, Philippine archipelago, Magnetic data, Tectonic Citation: Doo, W.

Balasubramanian University of Mysore 19-11-2011 Introduction Earth’s environmental segments include Atmosphere, Hydrosphere, lithosphere, and biosphere. Lithosphere is the basic solid sphere of the planet earth. It is the sphere of hard rock masses. The land we live in is on this lithosphere only. All other spheres are attached to this lithosphere due to earth’s gravity. Lithosphere is a massive and hard solid substratum holding the semisolid, liquid, biotic and gaseous molecules and masses surrounding it. All geomorphic processes happen on this sphere. It is the sphere where all natural resources are existing. It links the cyclic processes of atmosphere, hydrosphere, and biosphere. Lithosphere also acts as the basic route for all biogeochemical activities. For all geographic studies, a basic understanding of the lithosphere is needed. In this lesson, the following aspects are included: 1. The Earth’s Interior. 2.

Spakman8 Received 6 June 2005; revised 16 January 2007; accepted 2 March 2007; published 29 June 2007. [1] A unique GPS velocity field that spans the entire Southeast Asia region is presented. It is based on 10 years (1994–2004) of GPS data at more than 100 sites in Indonesia, Malaysia, Thailand, Myanmar, the Philippines, and Vietnam. The majority of the horizontal velocity vectors have a demonstrated global accuracy of 1 mm/yr (at 95% confidence level). The results have been used to (better) characterize the Sundaland block boundaries and to derive a new geokinematic model for the region. The rotation pole of the undeformed core of the Sundaland block is located at 49.0°N–94.2°E, with a clockwise rotation rate of 0.34°/Myr. With respect to both geodetically and geophysically defined Eurasia plate models, Sundaland moves eastward at a velocity of 6 ± 1 to 10 ± 1 mm/yr from south to north, respectively. Contrary to previous studies, Sundaland is shown to move independently with respect to South China, the eastern part of Java, the island of Sulawesi, and the northern tip of Borneo. The Red River fault in South China and Vietnam is still active and accommodates a strike-slip motion of 2 mm/yr.

The north–south-trending Accepted after revision 27 October 2015 Philippines archipelago (here named Philippine Mobile Belt, PMB), a few hundreds Available online xxx kilometers wide, is one of such complex tectonic zones. We show here that it is composed of rigid rotating crustal blocks (here called platelets). In Myanmar, the northernmost tip of Handled by Isabelle Manighetti the Sumatra-Andaman subduction system is another complex zone made of various Keywords: crustal blocks in-between convergent plates. Yet, contrary to PMB, it sustains internal Tectonics deformation with platelet buckling, altogether indicative of a non-rigid behavior. Geodynamics Therefore, the two case studies, Philippine Mobile Belt and Myanmar-Andaman micro- SE Asia plate (MAS), illustrate the complexity of micro-plate tectonics and kinematics at Micro-plates convergent plate boundaries. ß 2015 Acade´mie des sciences.

Abstract Understanding earthquakes and its prediction is most challenging tasks. Even though the earthquakes have been understood clearly, the prediction of earthquakes would take more time to come into reality. For this, collection of earthquake data and its interpretation plays a vital role. Its importance continues for few more decades in understanding the various aspects of earth structure and tectonic plate interactions. India, the second largest populous country of the world has experienced and is continuing to experience both inter and intra plate earthquakes, claiming life loss as well as damage to built environment.

Instructors can easily change the sequence of stops to suit their courses using the Google Earth desktop app or by editing the KML file.Because large placemark balloons tend to obscure the Google Earth terrain behind them, you are advised to keep Google Earth and this PDF document open in separate windows, preferably on separate monitors or devices.

Plate boundaries are from Laurel Goodell’s SERC web page: http://serc.carleton.edu/sp/library/google_earth/examples/ 49004.html based on Bird (2003) and programmed by Thomas Chust. Colors and line sizes were changed to improve visibility for persons with color vision deficiency, and I added other minor adjustments. The Tour Stops are arranged in a teaching sequence, Fig. 0.
