This book begins with the dynamic characteristics of the covering layer-bedrock type slope, containing monitoring data of the seismic array, shaking table tests, numerical analysis and theoretical derivation. Then it focuses on the landslide mechanism and assesment method. It also proposes a model that assesing thhe hazard area based on the field investigations. Many questions, exercises and so…
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…
All creatures presumably have some kind of awareness of their surroundings, and there is abundant evidence that some kind of mental imagery is a normal activity of the brain in at least the higher animals. How this takes place is still a mystery. This imagery ranges from purely pictorial recall such as a remembered face to artificial con-structs such as might occur in a fanciful dream. An indis…
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…
Man tends to term any change in his environment that affects his works or his life in an unwanted fashion as a "catastrophe". Therefore, catastrophes may not only be represented by sudden violent events, such as earthquakes or volcanic eruptions, but also by the gradual slow drowning of a city like Venice a process that may take centuries to run its course. In this book we shall deal only with …
The significant change in seismic activity for an active volcano is closely related to the stage of volcanic activity. Even in the dormancy period, the observation of seicmic activity of a particular volcano is very important to evaluate the status and to anticipate the future behavior. The Volcanological Survey of Indonesia installed triparti- te instruments at the Anak Krakatau and Sertung…
Pengukuran koordinat dan ketinggian ini dilakukan dengan sistem pelygon dengan titik dari triangulasi yang ada disekitar stasiun seismograf masing-masing.
Pada tanggal 7 Desember 1980 telah diadakan peninjauan kegiatan pengamatan G. Merapi oleh Bapak Sekretaris Jenderal Pertambangan dan Energi. Mendampingi beliau adalah Bapak Kepala Biro Hubungan Luar Negeri, Djayadi Hadikusumo, se-laku bekas pimpinan Sub Direktorat Vulkanologi, dan sebagai ahli gunungapi. Peninjauan kerja ini lebih bersifat in-cognito
Gunung Bromo yang tingginya 2329 m, terkenal di kalangan wisatawan sebagai tempat berlangsung 'Kesodo', Upacara keagamaan Hindu Budha, setiap setahun sekali bagi masyarakat Tengger.
Pengmatan gempa di G. Merapi dengan empat stasiun yaitu Bebadan, Plawangan, Musuk, dan Selo kurang memuaskan karena gempa vulkanik cenderung kecil.
