  • Volcanic eruptions are awesome and destructive; however, this natural phenomenon is beneficial in the long term. One of the earliest known written records of a natural disaster concerned the eruption of Pompeii in A.D. 79, and was recorded by Pliny the Younger in his letters to the historian Tacitus (Jashemski, 1979). Volcanic eruptions, ranging in intensity and numbering between 17 and 27 per year during the past decade (Bullard, 1984), continue to remind us of their potential impacts on the environment.

  • Volcanism witnesses every major change of our planet and other planets. In Advances in Volcanology, scientists from highly active volcanic countries, such as Japan, Italy, and New Zealand, as well as others from Germany, Portugal, and Russia, debate less commonplace themes. Topics from classic field volcanology, including practical problems with volcanic stratigraphy in oil exploitation, to the most modern techniques related to tomographic studies are discussed.

  • Concrete is an ancient material of construction, first used during the Roman Empire, which extended from about 20 B.C. to 200 A.D. The word concrete is derived from the Roman concretus, meaning to grow together. Although this early mixture was made with lime, cement, and a volcanic ash material called pozzolana, concrete today is a sophisticated material to which exotic constitutents can be added and, with computer-controlled batching, can produce a product capable of achieving 50,000 psi compressive strength....

  • Volcanic eruptions are among the Earth's most powerful and destructive forces. Imagine hearing a volcano erupt thousands of miles away. Imagine looking through binoculars and seeing the top of a mountain collapse. Imagine discovering an ancient Roman city that had been buried in volcanic ash. Volcanoes are also creative forces. The Earth's first oceans and atmosphere formed from the gases given off by volcanoes. In turn, oceans and an atmosphere created the environment that made life possible on our planet. Volcanoes have also shaped the Earth's landscape.

When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides, and occasionally volcanic activity

  • The search for oil occurs in geological sediments, as opposed to volcanic rocks. Several processes are involved in the creation of sediments. First, the inland continental volcanic rock is continuously being weakened and eroded by weathering processes (mechanical (through water, ice and wind) and chemical erosion). Secondly and simultaneously, the eroded material is being transported by water, ice and wind and gradually the material may be broken down into smaller pieces (from boulders to gravel, to sand, to silt and finally to clay).

  • These research teams study for example the impact and mechanisms of greenhouse gas emissions and atmospheric pollutant on climate, ozone depletion and carbon sinks (oceans and inland waters, forests and soil). They do research to understand the mechanisms and assess the impact of global change on the water cycle, water quality and availability, as well as soil functions and quality to provide the bases for management tools for sustainable water systems. Biodiversity and ecosystems are analysed to understand and minimise the negative impacts of human activities.

  • I t is a great honour and joy for me to present this volume of Scripta Varia which contains the papers presented during the Study Week on “Chemical Events in the Atmosphere and their Impact on the Environment” held at the seat of the Academy from the 7th to the 11th of November, 1983. The discussions which followed each presentation are included in the volume. These proceedings are of great interest; they touch on problems which may seem diverse for a non-knowledgeable person, or insignificant to those who flee the reality of our present world.
