Sejak tanggal 5 Agustus 2009 G. Ibu berstatus Siaga (level III). Hingga saai ini letusan abu dan hembusan masih sering terjadi. Pada akhir Maret 2010, berdasarkan informasi penduduk sekitar G. Ibu, terjadi guguran dari bibir kawah G. Ibu. Dalam upaya mitigasi, Tim Tanggap Darurat melakukan pemantauan kegiatan G. Ibu secara lebih intensif lagi.

During the past century, and most par-ticularly in the decades following World War II there has been a tremendous ex-pansion of the impact of science on everyday life. Explanations of scientific phenomena, particularly those of catastrophic effect on society, are given at all levels of education, science dominates the news media, most households make use of products that are the result of appli…
Fluid mechanics is a study of the behaviour of fluid at rest and in motion. The study takes into account the various properties of fluids and their ef-fects on the resulting flow patterns, in addition to the forces acting between the fluid and its boundaries. To explain observed fluid behaviour and to pre-diet fluid behaviour, the study and application of fundamental laws (conserva-tion of mass…
Kebutuhan untuk mengetahui medan geomagnet utama tanpa pengaruh faktor eksternal sangat besar bagi para surveyor pertambangan, pengguna atau penyedia navigasi satelit dan ilmuwan-ilmuwan yang mempelajari cuaca antariksa atau hubungan matahari bumi. Oleh karena itu dibuatlah suatu model geomagnet yang disepakati secara internasional yang dikenal sebagai model IGRF (International Geomagnetic Refe…
Maps are graphic representations of the cultural and physical environment. Two subclasses of maps exist: general-purpose (reference) maps and thematic maps. This text concerns the design of the thematic map, which shows the spatial distribution of some geographical phenomenon. Map scale, or the amount of reduction of the real world, is critical to the cartographer, since it determines selection…
To geologist, the field is where rocks or soils can be observed in place, and field geology consist of the methods used to examines and interpret structures and materials at the outcrop. Field studies are primary means of obtaining geologic knowledge. Some studies may be as simple as visiting a single outcrop or quarry, making notes and sketches on the relations between certain rocks, and colle…
Structural Geology brings together in condensed form the fundamentals of the geology of primary and secondary forms of occurrence of rocks sedimentary, igneous and metamorphic. It outlines the main principles of tectonics physics and set out the basic mechanism of folding and faulting. A classification of structural form is given and the processes governing their historical, mechanical and regi…
