Posttraumatic stress disorder among earthquake survivors of the Wenchuan area (Sichuan, China)
2014
Background : On May 12, 2008, an earthquake with a power of 8.0 M on the Richter scale occurred in the Wenchuan County of Sichuan Province in southwest China, which was unprecedented in magnitude and aftermath. Approximately 70,000 people were killed and nearly 20,000 went missing. The earthquake caused a wide number of mental and physical health outcomes among survivors, and posttraumatic stress disorder (PTSD) was one of the most commonly studied. Methods : We conducted a systematic overview to assess research achievements about PTSD in the past 6 years after the Wenchuan earthquake, including symptoms and risk factors about PTSD among Wenchuan earthquake survivors, as well as research de…
GIBELLINA: VANGUARD OF A COSMOPOLITAN CITY
2021
Gibellina is a city formed by orogenesis. It was reborn after a dramatic earthquake and shook the sediment off urban theory, becoming a city open to the world and to the worlds of contemporary culture; of architecture, art, theatre. To understand its revolutionary force, we must immerse ourselves in the context of 1968, when an earthquake hit the Belice Valley with a violence capable of damaging fourteen cities and razing four of them—including Gibellina— to the ground. The earthquake marked a sharp break in the historical continuity of the small, rural centre of Sicily. The original site of the town was abandoned and another city was built from scratch for the surviving inhabitants. The ci…
The Bossons glacier protects Europe's summit from erosion
2013
13 pages; International audience; The contrasting efficiency of erosion beneath cold glacier ice, beneath temperate glacier ice, and on ice-free mountain slopes is one of the key parameters in the development of relief during glacial periods. Detrital geochronology has been applied to the subglacial streams of the north face of the Mont-Blanc massif in order to estimate the efficiency of erosional processes there. Lithologically this area is composed of granite intruded at ~303 Ma within an older polymetamorphic complex. We use macroscopic features (on ~10,000 clasts) and U-Pb dating of zircon (~500 grains) to establish the provenance of the sediment transported by the glacier and its subgl…
Effect of epicentral direction on seismic response of asymmetric buildings
1984
The paper deals with the influence of the epicentral direction on the displacement and stress response of multistorey asymmetric buildings to earthquake horizontal ground motion. A method is given for computing for each plane frame of the complex structure a particular direction of the bidirectional stationary random input for which the horizontal floor displacement of the given frame is maximized. It is shown that this direction can be considered conservative for the corresponding non-stationary process.
In-soil radon anomalies as precursors of earthquakes: A case study in the SE slope of Mt. Etna in a period of quite stable weather conditions
2012
In-soil radon concentrations as well as climatic parameters (temperature, atmospheric pressure and relative humidity) were collected in St. Venerina (Eastern Sicily - Italy) from March 19th to May 22nd 2009, close to an active fault system called Timpe Fault System (TFS), which is strictly linked to the geodynamics of Mt. Etna. During the monitoring period no drastic climatic variations were observed and, on the other hand, important seismic events were recorded close to the monitoring site. A seismic swarm composed of 5 earthquakes was observed in the Milo area on March 25th (M-max = 2.7) at just 5.1 km from the site, and on May 13th an earthquake of 3.6 magnitude was recorded in the terri…
The Nymphaeum of the Tritons at Hierapolis of Phrygia (Turkey) from excavations to 3D-virtual reconstruction: an example of integrated methods in the…
2011
The Nymphaeum of the Tritons at Hierapolis of Phrygia is a monumental fountain of the Roman period with an imposing marble façade. Within the activities of the Italian Archaeological Mission the Nymphaeum is currently being studied by a team from the University of Messina with the goal of understanding its original layout and its history. The starting point of the study is the wealth of data provided by stratigraphic excavation of the building, particularly by the extensive archaeological deposits formed by the blocks of the façade collapsed into the pool of the fountain following an earthquake in the 7th century AD. The need to process a large amount of data required the creation of a comp…
Il terremoto del 1542 in Val di Noto: i casi di Lentini e Siracusa, dalla gestione dell'emergenza al rinnovamento urbano
2012
All’interno del più generale quadro delle distruzioni e ricostruzioni di interi centri urbani o significative parti degli stessi conseguente al terremoto che nel 1542 colpì violentemente il Val di Noto, questo contributo analizza due casi studio di particolare interesse e chiaramente esemplificativi delle problematiche in campo, nonché delle strategie e modalità di intervento e dei processi di rinnovamento attivati dall’evento distruttivo. Nel caso di Lentini, le vicende conseguenti al terremoto agevolano la formulazione di un progetto di ricostruzione dell’intera città in altro sito che avrebbe soddisfatto anche esigenze di natura difensiva. Le opposizioni incontrate a livello locale fanno…
An Overview of Public Concerns During the Recovery Period after a Major Earthquake: Nepal Twitter Analysis
2016
In responding to disasters, Twitter is extensively used, both for information exchange and mapping the crisis, among citizens, and in relation to national and international humanitarian responders. This paper reports Twitter analysis aimed at identifying the most pressing issues that arose in the short term recovery phase starting about a week after the Nepal earthquake, including the heretofore neglected topic of mismatch between international relief and local cultures. Based on Twitter data collected between April 30th and May 6th 2015. 1,074,864 raw messages apparently related to the Nepal earthquake were retrieved, filtered and analyzed. This exploratory adapts established frameworks fo…
Bi-objective multi-layer location–allocation model for the immediate aftermath of sudden-onset disasters
2019
International audience; Locating distribution centers is critical for humanitarians in the immediate aftermath of a sudden-onset disaster. A major challenge lies in balancing the complexity and uncertainty of the problem with time and resource constraints. To address this problem, we propose a location–allocation model that divides the topography of affected areas into multiple layers; considers constrained number and capacity of facilities and fleets; and allows decision-makers to explore trade-offs between response time and logistics costs. To illustrate our theoretical work, we apply the model to a real dataset from the 2015 Nepal earthquake response. For this case, our method results in…
Managing in-country transportation risks in humanitarian supply chains by logistics service providers: Insights from the 2015 Nepal earthquake
2017
International audience; Humanitarian supply chains (HSCs) play a central role in effective and efficient disaster relief operations. Transportation has a critical share in HSCs and managing its risks helps to avoid further disruptions in relief operations. However, there is no common approach to or culture of risk management that its applicability has been studied through recent cases. This paper incorporates an empirical research design and makes a threefold contribution: first, it identifies in-country transportation risks during Nepal response. Second, we evaluate afore identified risks through an expert driven risk assessment grid. Third, we use our field data to study how some humanita…
