A Monte Carlo approach for deriving flood frequency curves in ungauged basins in Sicily region (Italy) is proposed. The procedure consists of: (i) a regional frequency analysis of extreme rainfall series, combined with Huff curves-based synthetic hyetographs, for design storms and (ii) a rainfall-runoff model, based on the Time-Area technique, to generate synthetic hydrographs. Validation of the procedure is carried out on four gauged river basins in Sicily (Italy) with promising results.

Throughout history, the city of Rome has experienced numerous flooding events from the Tiber river. Ancient Rome mostly developed on the hills, while the Tiber’s floodplain was mainly used for agricultural purposes. Instead, many people live nowadays in modern districts in the Tiber’s floodplain, often unaware of their exposure to potentially flooding. This research work aims to explore the dynamics of changing flood risk between these two opposite pictures of ancient and contemporary Rome.

Eastern Sicily is affected by earthquakes and tsunamis of localand remote origin, which is known through numerous historical chronicles.Recent studies have put emphasis on the role of submarine landslides as thedirect cause of the main local tsunamis, envisaging that earthquakes (in 1693and 1908) did produce a tsunami, but also that they triggered mass failuresthat were able to generate an even larger tsunami. The debate is still open,and though no general consensus has been found among scientists so far, thisresearch had the merit to attract attention on possible generation oftsunamis by landslides off Sicily. In this paper we investigate the tsunamipotential of mass failures along one sector of the Hyblean-Malta Escarpment(HME). facing Augusta. The HME is the main offshore geological structure ofthe region running almost parallel to the coast, off eastern Sicily. Here,bottom morphology and slope steepness favour soil failures. In our work westudy slope stability under seismic load along a number of HME transects byusing the Minimun Lithostatic Deviation (MLD) method, which is based on thelimit-equilibrium theory. The main goal is to identify sectors of the HMEthat could be unstable under the effect of realistic earthquakes. We estimatethe possible landslide volume and use it as input for numerical codes tosimulate the landslide motion and the consequent tsunami. This is animportant step for the assessment of the tsunami hazard in eastern Sicily andfor local tsunami mitigation policies. It is also important in view oftsunami warning system since it can help to identify the minimum earthquakemagnitude capable of triggering destructive tsunamis induced by landslides,and therefore to set up appropriate knowledge-based criteria to launch alertto the population.

AlpArray is a collaborative seismological project in Europe that includes ~ 50 research institutes and seismological observatories. At its heart is the collection of top-quality seismological data from a dense network of stations in the Alpine region: the AlpArray Seismic Network (AASN). We report the Swiss contribution: site selections, installation, data quality and management. We deployed 27 temporary BB stations across 5 countries as result of a fruitful collaboration between 5 institutes.

This Paper endeavors to find or understand the relationships between tuna landings and dramatic events as El Niño in the Central Eastern Pacific and visualize the impact of long term oscillations, like the Pacific decadal Oscillation (PDO). Here for the first time tuna landing, fish efforts and the El Niño indexes (ONI and MEI) are correlated to find how the later affect the tuna fishery. Special attention has been put on tuna landings in Ecuador.

We investigate the factors that determine the longer lead ENSO predictability in the 1980-2012 period. We compare different versions of the prediction model using some variables that contain tropical or extratropical information.We observe that where tropical predictors are used the prediction reproduces only the equatorial characteristics of the warming (cooling). However, where extratropical predictors are included, the predictions are able to simulate the absorbed warming in the SPCZ.

The paper originally presented a different approach to using the El Niño indexes (ONI and MEI) in relation to small pelagic landings in Ecuador. Apart from finding relationships from a statistical point of view, the results of present work give an idea how much high- and low-frequency events can affect these fisheries, which are very important for the Ecuadorian economy and an employment asset. These results will enable fishermen and fish resource managers to somehow see ahead in a short time.

Weather forecasters in Maritime Continent countries base their weekly outlooks on the seasonal progression of the monsoon wind systems. The onset of the monsoon was compared between El Niño and La Niña years using satellite sea surface winds. Rather than being delayed throughout the Maritime Continent during El Niño years, the monsoon was seen to arrive faster at and remain longer over the western Maritime Continent, and therefore delayed for the eastern Maritime Continent.

We studied the relationship between the midsummer drought (MSD) in Central America, and the sea surface temperatures (SST) of the neighbouring ocean in interannual scales. Besides, the motivation of this study is also to provide a systematic method for forecasting the MSD period. We found that the intensity and the magnitude of the MSD shown a strong association with the contrast in the surface temperatures between the eastern tropical Pacific, and the tropical north Atlantic.

Since 2002 OGS in Italy, ZAMG in Austria and ARSO in Slovenia were exchanging seismic data in real time via internet. This was not good for civil defense scopes because internet is not reliable: therefore, in 2012 the Protezione Civile di Bolzano in Italy joined OGS, ZAMG and ARSO in the Interreg IV Italia-Austria "SeismoSAT" project aimed in connecting the seismic data centers in real time via satellite.

The Institute of Seismology of University of Helsinki is building a newlocal seismic network, called OBF network, around planned nuclear powerplant in Northern Ostrobothnia, Finland. The network will consist of ninenew stations and one existing station. The network should be dense enough toprovide azimuthal coverage better than 180° and automatic detectioncapability down to ML −0.1 within a radius of 25 km from the site.The network construction work began in 2012 and the first four stationsstarted operation at the end of May 2013. We applied an automatic seismicsignal detection and event location system to a network of 13 stationsconsisting of the four new stations and the nearest stations of Finnish andSwedish national seismic networks. Between the end of May and December2013 the network detected 214 events inside the predefined area of 50 kmradius surrounding the planned nuclear power plant site. Of thosedetections, 120 were identified as spurious events. A total of 74 eventswere associated with known quarries and mining areas. The average locationerror, calculated as a difference between the announced location fromenvironment authorities and companies and the automatic location, was 2.9 km.During the same time period eight earthquakes between magnitude range0.1–1.0 occurred within the area. Of these seven could be automaticallydetected. The results from the phase 1 stations of the OBF network indicatesthat the planned network can achieve its goals.

Acute diarrhoea diseases (ADDs) are one of the major health problems in Aguascalientes, Mexico. Due to the risk of significant increases of ADDs in the hot season, it has been necessary to determine the weather conditions that might lead to escalating ADD events. The effects of El Niño and La Niña phenomena on the morbidity rate of ADD (MRADD) in the State of Aguascalientes were determined during the period of 2000–2010. The MRADD was calculated from cases reported by the State Health Department.

The ENSO phenomenon is one of the key factors that influence the interannual variability of precipitation over Southern South America. We identified the regional response of precipitation to El Niño/La Niña events, with emphasis in drought conditions. We found coherent and significant precipitation responses to ENSO phases at a regional level, with deficits under La Niña conditions. The results provide critical baseline information for the agricultural and water resources sectors.
- Coral-rubble ridges as dynamic coastal features – short-term reworking

Abstract: Coral-rubble ridges as dynamic coastal features – short-term reworking and weathering processes
Adv. Geosci., 38, 55-61, doi:10.5194/adgeo-38-55-2016, 2016
A coastal ridge on Anegada was surveyed in 2013 and 2015 to document short-term changes in morphology and weathering. Minor storms changed the ridge morphology and added new clasts to the lower parts. Observations imply that the ridge was initially emplaced during a more severe event; minor storms are only able to modify preexisting ridges. Second, bioweathering is a rapid process in tropical settings, as proven by the fact that white coral clasts in 2013 already depicted a grey patina in 2015.

The last century, the global urbanization has leaded the majority ofpopulation to move into big, metropolitan areas. Small areas on the Earth'ssurface are being built with tall buildings in areas close to seismogeniczones. Such an area of great importance is the Hellenic arc in Greece. Amongthe regions with high seismicity is Crete, located on the subduction zone ofthe Eastern Mediterranean plate underneath the Aegean plate. The HellenicSeismological Network of Crete (HSNC) has been built to cover the need oncontinuous monitoring of the regional seismicity in the vicinity of theSouth Aegean Sea and Crete Island. In the present work, with the use ofZ-map software the spatial variability of Magnitude of Completeness (Mc) iscalculated from HSNC's manual analysis catalogue of events from thebeginning of 2008 till the end of September 2015, supporting the goodcoverage of HSNC in the area surrounding Crete Island. Furthermore, wediscuss the 2013 seismicity when two large earthquakes occurred in thevicinity of Crete Island. The two main shocks and their aftershock sequenceshave been relocated with the use of HYPOINVERSE earthquake locationsoftware. Finally, the quality of seismological stations is addressed usingthe standard PQLX software.
