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. -
Plate Motions, Slab Dynamics and Back-Arc Deformation Arnauld Heuret∗, Serge Lallemand
Physics of the Earth and Planetary Interiors 149 (2005) 31–51 Plate motions, slab dynamics and back-arc deformation Arnauld Heuret∗, Serge Lallemand Laboratoire de Dynamique de la Lithosphere, Institut des Sciences de la Terre, de l’Environnement et de l’Espace de Montpellier (ISTEEM), CNRS—Universit´e Montpellier 2, CC. 60, place E. Bataillon, 34095 Montpellier cedex 5, France Received 12 September 2003; received in revised form 22 March 2004; accepted 26 August 2004 Abstract Back-arc extension or compression is often related to a particular behavior of the slab (dip change and/or forward/backward migration) with respect to the upper plate. Slabs act, either passively when anchored in the deep mantle whereas back-arc deformation accommodates the backward or forward motion of the upper plate with respect to the trench; or actively when slab pull – increasing with slab age – forces the trench to rollback. In addition to these two mechanisms, i.e., slab anchor and slab rollback, numerous observations support the existence of dynamic mantle flow that can exert an overpressure on one side of the slab, causing its forward or rearward migration with respect to the arc. Based on a compilation of upper plate absolute motion, trench absolute motion, back-arc deformation rate, upper plate strain regime and slab age for all oceanic subduction zones—excluding any kind of collision with continents, arcs or plateaus, we have examined how the combined effects of these parameters can account for the observed back-arc deformations. Our main results are: -
Is the Ryukyu Subduction Zone in Japan Coupled Or Decoupled? —The Necessity of Seafloor Crustal Deformation Observation
Earth Planets Space, 61, 1031–1039, 2009 Is the Ryukyu subduction zone in Japan coupled or decoupled? —The necessity of seafloor crustal deformation observation Masataka Ando1, Mamoru Nakamura2, Takeshi Matsumoto2, Masahide Furukawa2, Keiichi Tadokoro3, and Muneyoshi Furumoto3 1Institute of Earth Sciences, Academia Sinica, Taiwan 2Department of Earth and Material Sciences, University of Ryukyus, Japan 3Graduate School of Environmental Sciences, Nagoya University, Japan (Received July 19, 2008; Revised April 21, 2009; Accepted June 3, 2009; Online published November 10, 2009) The 2004 Sumatra-Andaman earthquake of Mw 9.3 occurred in a region where a giant earthquake seemed unlikely from the point of view of tectonics. This clearly implies that our current understanding of strain accumulation processes of large earthquakes at subduction zones needs to be reexamined. The Ryukyu subduction zone is one such zone since no large earthquake has been anticipated there for reasons similar those pertaining to the Sumatra-Andaman arc. Based on our analysis of historical earthquakes, plate motion, back-arc spreading, and GPS observation along the Ryukyu trench, we highly recommend monitoring seafloor crustal deformation along this trench to clarify whether a large earthquake (Mw >8) could potentially occur there in the future. Key words: Subduction zones, Ryukyu trench, decoupled/couple subduction, back-arc spreading, seafloor crustal deformation. 1. Introduction the possibility of such earthquakes along the Ryukyu sub- Japan is surrounded by the major subduction plate bound- duction. There are four main reasons why this giant earth- aries with the Pacific plate, Philippine Sea plate, and Amur quake was not expected for the Sumatra-Andaman arc. -
A Decade of GPS in Southeast Asia: Resolving Sundaland Motion and Boundaries W

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. -

Box 968, Taipei, Taiwan b Department of Geosciences, National Taiwan University, Taipei, Taiwan c Department of Geosciences, National Taiwan University, Taiwan Available online 22 November 2007 Abstract We analyze the current deformation in Ilan Plain of northeastern Taiwan considered as the western extension of Okinawa Trough based on 34 geodetic sites observed between 2002 and 2006. The station velocities are between 1.9 mm/yr and 43.0 mm/yr in a direction between 38 ° and 143 ° relative to stable continent margin of Eurasian plate. This largest velocity is moving southeastward (143 °) at a rate of ~43 mm/yr was enhanced by a seismic doublet that occurred on March 6, 2005. The station velocities at the northern margin of Ilan Plain are insignificant with a magnitude of ~1.9 mm/yr to ~7.5 mm/yr. On the contrary, the station velocities increase approximately southward along the southern margin of Ilan Plain. The stations are moving roughly E–W with a magnitude of ~5.8 mm/yr to ~21.8 mm/yr. Further southward, the station velocities increase to a value of ~43.0 mm/yr in a direction of 143 °.
