Comparison of event landslide inventories: the Pogliaschina catchment test case, Italy
Natural Hazards and Earth System Sciences - Tập 14 Số 7 - Trang 1749-1759
Alessandro Mondini, E. Villanueva, Marco Cavalli, Lorenzo Marchi, Gerardo Herrera, Fausto Guzzetti
Abstract. Event landslide inventory maps document the extent of populations of landslides caused by a single natural trigger, such as an earthquake, an intense rainfall event, or a rapid snowmelt event. Event inventory maps are important for landslide susceptibility and hazard modelling, and prove useful to manage residual risk after a landslide-triggering event. Standards for the preparat...... hiện toàn bộ
Evaluation of far-field tsunami hazard in French Polynesia based on historical data and numerical simulations
Natural Hazards and Earth System Sciences - Tập 7 Số 2 - Trang 195-206
Anthony Sladen, Hélène Hebert, François Schindelé, D. Reymond
Abstract. The first tsunami hazard map of French Polynesia is presented here on the basis of historical data, and numerical simulations. French Polynesia, because of its central position in the most tsunami prone ocean, the Pacific, is strongly exposed to far-field tsunamis. As no previous study on the area had been conducted, we compiled catalogues of all the historical observations (14 ...... hiện toàn bộ
Microseismic activity analysis for the study of the rupture mechanisms in unstable rock masses
Natural Hazards and Earth System Sciences - Tập 10 Số 4 - Trang 831-841
David Amitrano, M. Arattano, Marta Chiarle, G. Mortara, Cristina Occhiena, Marina Pirulli, Claudio Scavia
Abstract. Rockfalls are common instabilities in alpine areas and can cause significant damage. Since high mountains have been affected by an increasing number of these phenomena in the last years, a possible correlation with permafrost degradation induced by climate change has been hypothesized. To investigate this topic, a monitoring system, made of 5 triaxial geophones and 1 thermometer...... hiện toàn bộ
Quan sát và mô hình hóa quá trình khởi phát dòng chảy bùn trượt đất trong các lớp trầm tích bột núi lửa: sự kiện Sarno 1998 Dịch bởi AI
Natural Hazards and Earth System Sciences - Tập 3 Số 1/2 - Trang 53-69
Giovanni B. Crosta, P. Dal Negro
Tóm tắt. Các loại đất bột núi lửa bao phủ một diện tích rộng lớn của dãy Apennine Campania đang phải chịu các hiện tượng bất ổn định lặp đi lặp lại. Nghiên cứu này phân tích sự kiện xảy ra vào ngày 5 và 6 tháng 5 năm 1998 đã ảnh hưởng đến Pizzo d’Alvano (Campania, miền nam Italy). Hơn 400 vụ trượt liên quan đến các lớp trầm tích bột núi lửa cạn đã được kích hoạt bởi mưa lớn kéo dài nhưng k...... hiện toàn bộ
Brief communication: Meteorological and climatological conditions associated with the 9 January 2018 post-fire debris flows in Montecito and Carpinteria, California, USA
Natural Hazards and Earth System Sciences - Tập 18 Số 11 - Trang 3037-3043
Nina S. Oakley, Forest Cannon, Robert J. Munroe, Jeremy T. Lancaster, David Gomberg, F. Martin Ralph
Abstract. The Thomas Fire burned 114 078 ha in Santa Barbara and Ventura counties, southern California, during December 2017–January 2018. On 9 January 2018, high-intensity rainfall occurred over the Thomas Fire burn area in the mountains above the communities of Montecito and Carpinteria, initiating multiple devastating debris flows. The highest rainfall intensities occurred with the pass...... hiện toàn bộ
Testing the impact of direct and indirect flood warnings on population behaviour using an agent-based model
Natural Hazards and Earth System Sciences - Tập 20 Số 8 - Trang 2281-2305
Thomas O'Shea, Paul Bates, Jeffrey Neal
Abstract. This paper uses a coupled hydrodynamic agent-based model (HABM) to investigate the effect of direct or indirect warnings in flood incident response. This model uses the LISFLOOD-FP hydrodynamic model and the NetLogo agent-based framework and is applied to the 2005 flood event in Carlisle, UK. The hydrodynamic model provides a realistic simulation of detailed flood dynamics throug...... hiện toàn bộ
Scenario-based multi-risk assessment from existing single-hazard vulnerability models. An application to consecutive earthquakes and tsunamis in Lima, Peru
Natural Hazards and Earth System Sciences - Tập 23 Số 6 - Trang 2203-2228
Juan Camilo Gómez Zapata, Massimiliano Pittore, Nils Brinckmann, Juan Lizarazo-Marriaga, Sergio Ordóñez, Nicola Tarque, Fabrice Cotton
Abstract. Multi-hazard risk assessments for building portfolios exposed to earthquake shaking followed by a tsunami are usually based on empirical vulnerability models calibrated on post-event surveys of damaged buildings. The applicability of these models cannot easily be extrapolated to other regions of larger/smaller events. Moreover, the quantitative evaluation of the damages related t...... hiện toàn bộ
Hazard interaction analysis for multi-hazard risk assessment: a systematic classification based on hazard-forming environment
Natural Hazards and Earth System Sciences - Tập 16 Số 2 - Trang 629-642
Baoyin Liu, Yim Ling Siu, Gordon Mitchell
Abstract. This paper develops a systematic hazard interaction classification based on the geophysical environment that natural hazards arise from – the hazard-forming environment. According to their contribution to natural hazards, geophysical environmental factors in the hazard-forming environment were categorized into two types. The first are relatively stable factors which construct the...... hiện toàn bộ
Atmospheric correction for satellite remotely sensed data intended for agricultural applications: impact on vegetation indices
Natural Hazards and Earth System Sciences - Tập 10 Số 1 - Trang 89-95
Diofantos G. Hadjimitsis, George Papadavid, Άθως Αγαπίου, Kyriacos Themistocleous, Marinos G. Hadjimitsis, Adrianos Retalis, Silas Michaelides, Nektarios Chrysoulakis, Leonidas Toulios, C.R.I. Clayton
Abstract. Solar radiation reflected by the Earth's surface to satellite sensors is modified by its interaction with the atmosphere. The objective of applying an atmospheric correction is to determine true surface reflectance values and to retrieve physical parameters of the Earth's surface, including surface reflectance, by removing atmospheric effects from satellite images. Atmospheric co...... hiện toàn bộ
An observational study of the 7 September 2005 Barcelona tornado outbreak
Natural Hazards and Earth System Sciences - Tập 7 Số 1 - Trang 129-139
Joan Bech, Ramón Pascual, Tomeu Rigo, Nicolau Pineda, J.M. López, Joan Arús, Miquel Gayà
Abstract. This paper presents an observational study of the tornado outbreak that took place on the 7 September 2005 in the Llobregat delta river, affecting a densely populated and urbanised area and the Barcelona International airport (NE Spain). The site survey confirmed at least five short-lived tornadoes. Four of them were weak (F0, F1) and the other one was significant (F2 on the Fuji...... hiện toàn bộ
