Central America comprises 7 countries (Fig. 1.1) that cover 50 million hectares extending over different ecoregions (Fig. 1.2a) and shelter nearly 39 million people (2003). With a relatively high population density (71 inhabitants/km2), Central America is one of the world’s regions most prone to geology-related and climaterelated natural disasters. Earthquakes and volcanic eruptions, which are related to the Central American tectonic setting, and landslides, which are either earthquake induced or rainfall-related, are the most severe geological burdens of the region. Central America also is afflicted by several climatic hazards, particularly droughts and hurricanes, which may be accompanied by secondary hazards, including high winds, flooding and landslides.
Since the earliest days of NMR, it has been recognized that the technique can provide information on matters concerning the disposition of atoms in the unit cells of crystals. Thus, the distance between protons in the water molecules of gypsum, CaSO4 · 2H2O, was determined by Pake and reported as 1.58 A in 1948. However, the term NMR crystallography has only recently come into common usage, and even now causes raised eyebrows within some parts of the diffraction community. On the other hand, the power of solid-state NMR to give crystallographic information has considerably increased since the CPMAS suite of techniques was introduced in 1976.

Oil, natural gas, and oilfield water are all stored in the pores of underground rocks. Influenced by their sources and geological factors, their chemical compositions and physical properties vary from one region to another. Understanding the basic properties of oil, gas, and water is of great significance for clarifying the formation, migration, and accumulation patterns of oil and gas, and for developing rational exploitation and processing plans. This chapter mainly introduces the chemical composition, physical properties, and classification of petroleum, natural gas, and oilfield water. It also briefly discusses the stable isotopes in oil and gas, particularly the compositional characteristics of stable carbon isotopes. <...>
Humankind first began to create imagery as a means of communication some 7,500 years ago. The writing, back then, was literally on the wall. It began with cave art, and then was engraved into stone blocks. These first protolanguages used pictures as literal depictions of events, and this evolved into a system of simpler symbols that were representative of the sounds used in speech.

The main volcanological concept is shown and expressed so that any volcano can be understood easily. Volcanic products are listed and explained in plain language from lava flow to various pyroclastic products. The volcanic products have been explained schematically and their textural, field relationships characteristics are highlighted. The origin of magma within the interior of the Earth is also explained and the link between mantle and crust has been shown. The relationship among crust, mantle, and core has been highlighted embracing the source-to-surface model. An updated explanation of the Pyroclastic Density Currents (PDC) has been done to perceive their danger. Some of the most successful Volcanology books have been used. This will help the students, with a passion for Volcanology, to understand the principles of Volcanology. <...>
