The Toba Caldera Complex
The Toba Caldera in Indonesia is one of the most remarkable volcanic features formed during Quaternary geologic time. Its rich history of research for over a century has yielded important information on the physical volcanology of silicic calderas and super-eruptions, geochemical evolution of silicic magma bodies, and geophysical imaging of active sub-volcanic systems. During the past 1.3 my, t...
متن کاملAsh from the Toba supereruption in Lake Malawi shows no volcanic winter in East Africa at 75 ka.
The most explosive volcanic event of the Quaternary was the eruption of Mt. Toba, Sumatra, 75,000 y ago, which produced voluminous ash deposits found across much of the Indian Ocean, Indian Peninsula, and South China Sea. A major climatic downturn observed within the Greenland ice cores has been attributed to the cooling effects of the ash and aerosols ejected during the eruption of the Younges...
متن کاملApplying STAMP in Accident Analysis∗
Accident models play a critical role in accident investigation and analysis. Most traditional models are based on an underlying chain of events. These models, however, have serious limitations when used for complex, socio-technical systems. Previously, Leveson proposed a new accident model (STAMP) based on system theory where the basic concept is not an event but a constraint. This paper shows ...
متن کاملReply to Roberts et al.: A subdecadal record of paleoclimate around the Youngest Toba Tuff in Lake Malawi.
Roberts et al. (1) state that we found no evidence of climate change at multidecadal to millennial timescales following deposition of the Youngest Toba Tuff (YTT) in Lake Malawi (2). However, we examined smear slides at a 2-mm interval, corresponding to subdecadal resolution, and X-ray fluorescence scans run at 200-μm intervals correspond to subannual resolution. We observed no obvious change i...
متن کاملanalysis of power in the network society
اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
