Structural map of the western Pacific Ocean<\/strong><\/p>\n

This map is based on physiographic, geological and geophysical data illustrating the structure of the region. Magnetic anomalies and the age of the seabed are shown in order to provide the reader with a precise and easy-to-read document. The colours and symbols used are identical to those used on previous 1:20 million scale maps of the oceans published by the CGMW, i.e. the structural maps of the Indian and Atlantic Oceans.<\/p>\n

The representation of continental geology is limited to that of volcanism associated with the formation of oceanic margins. It is shown as island arc and ophiolite magmatism (relics of oceanic lithosphere carried onto the continental crust, obduction).<\/p>\n

In order to maintain the readability of the A0 format printed version, the Structural Map of the Western Pacific Ocean includes the structural map, accompanied by a geodynamic diagram of the regional environment. A reduced image of the map showing the epicentres of earthquakes is provided in the explanatory notes (in English only, at download here<\/a>). The pdf file of this map at the original scale of 1:20 million is available (click here). here to download<\/a>).<\/p>\n
