Geodynamics, the study of global movements and of the forces driving them, is a rekatively fresh offshoot from the vigorously branching tree of the earth sciences. Before the advent of Alfred Wegener on this scene in the early nineteen-hundreds, the idea of permanency in the distribution of continents and oceans was almost sacrosanct.
Das Antlitz der Erde, or “The Face of the Earth”, was the title of the first great magnum opus on the gross surface features of the earth by Eduard Suess late last century. A recent British television documentary with the same purpose bore the same title.
Batumulia dapat digolongkan dalam tiga bagian yakni; jenis batu permata (precious stones), setengah batu permata (semi precious stones ), dan jenis batu hias ( ornamental stones). Batumulia jenis batu permata adalah mineral yang mempunyai daya tarik yang terdapat di alam dan setelah dilakukan pemrosesan maka keindahannya semakin bertambah dari bentuk asalnya.Pada umumnya jenis batu permata …
The tectonic concept known as seafloor spreading , global tectonics and also as plate tectonics began engulfing the geological community in the early sixties. Within less than a decade this unifying, geotectonic hypothesis beame widely known, and judging from the current literature, it has also been widely accepted.
The monograph Geothermal Resources: An Energy Alternative by Harsh K. Gupta presents for the first time a readable, coherent account of all facets of geothermal energy development. The development of alternative, renewable energy resources during the past decade has been spurred by a crunch in the supplies of traditional hydrocarbon energy resources, which have previously been inexpensive and r…
This book is based at the level of a bachelor’s degree in physical science. Experience at Standford indicate that a one-semester class in engineering systems theory provides helpful additional background. It will be readable to a general science and engineering audience and should be useful to anyone interested in computer modelling and data analysis in physical sciences.

This report which describes the geological setting and physical features of the most important coal deposits in Central Sumatra is based on detailed studies over 13 years by the Sub-Directorate of Coal and Peat Exploration, which is the most experienced and well equipped government coal exploration group in this country. The Sub-Directorate of Coal and Peat Exploration within the Directorate…
Melihat dari sejarah letusan gunungapi di Indonesia, sudah sangat banyak gunungapi di Indonesia yang meletus sejak tahun 1600. Salah satu gunungapi yang masih aktif sampai sekarang adalah Gunungapi Ili Lewotolok yang terletak di Nusa Tenggara Timur.
Dengan menggunakan ilmu geodesi, kondisi aktivitas gunungapi dapat dipantau sehingga banyak sekali metode di bidang geodesi yang digunakan untuk pemantauan gunungapi, salah satunya metode deformasi. Metode deformasi membantu dalam pemantauan aktivitas gunungapi dengan memberikan petunjuk mengenai apa yang terjadi jauh di bawah permukaan tanah.
