Article
Full-text available
The Arkalochori village in central Crete was hit by a large earthquake (Mw = 6.0) on 27 September 2021, causing casualties, injuries, and severe damage to the infrastructure. Due to the absence of apparent surface rupture and the initial focal mechanism solution of the seismic event, we initiated complementary, multi-disciplinary research by combin...

Technical report with multiple authors (please refer to pdf), edited by Anastasios Sextos, Basil Margaris and Nikolaos Klimis. Coordinated by the Hellenic Association of Earthquake Engineering, the Institute of Engineering Seismology and Earthquake Engineering (ITSAK-EPPO) and Democritus University of Thrace with the collaboration of Aristotle Univ...

Rising groundwater in abandoned mines may result in ground movements at the surface overlying underground works. Feedbacks on several abandoned coalfields show that ground uplift is generally observed, reaching in some cases several centimetres or more. Although such ground movements, slow and associated with slight slopes, are not expected to gene...

On 11 November 2019, a 5 magnitude earthquake occurred in southeast France at Le Teil, close to the Rhone river. This seismic event is the strongest earthquake ever felt in France since the Arette (Pyrenees) earthquake in 1967. By using an updated 3D geological model, we focus this work on the comparison of the effect of hydraulic recharge linked t...

A sequence of earthquakes occurred on March 3rd and 4th in Northern Thessaly, northern Greece, associated with previously unknown, blind normal faults within the crystalline Palaeozoic basement of the Pelagonian geotectonic zone. Surficial ground deformation, such as liquefaction phenomena in fluvial plains, as well as soil fissures and rock falls,...

New capabilities for measuring and monitoring are needed to prevent the shrink-swell risk caused by drought-rewetting cycles. A clayey soil in the Loire Valley at Chaingy (France) has been instrumented with two extensometers and several soil moisture sensors. Here we show by direct comparison between remote and in situ data that the vertical ground...

On 3 March 2021, the Mw6.3 Tyrnavos earthquake shook much of the Thessalia region, leading to extensive damage in many small towns and villages in the activated area. The first main shock was followed in the next day, on 4th of March 2021, by an “equivalent” main shock with Mw6.0 in the adjacent fault segment. These are the largest earthquakes to s...

In this study, we present a new method called BathySent to retrieve shallow bathymetry from space that is based on the joint measurement of ocean wave celerity (c) and wavelength (λ). We developed the method to work with Sentinel 2 data, exploiting the time lag between two Sentinel 2 spectral bands, acquired quasi-simultaneously, from a single sate...

The proposed novel approach "BathySent" for coastal bathymetric mapping, using the Copernicus Sentinel-2 mission, as well as the assessment and specification of the uncertainties of the derived depth results are the objectives of this research effort. For this reason, Sentinel-2 bathymetry retrieval results for three different pilot sites in Greece...
Technical Report

On 30 October 2020, an M 7.0 earthquake occurred north of Samos Island. The fault rupture caused sudden lowering of the seafloor, which produced a tsunami that mainly impacted nearby Samos Island as well as a series of Anatolian cities along the coast of Seferihisar Bay, with maximum runup and inundation lengths of about 3.8 m and 2500 m, resulting...

The road network of metropolitan Rome is determined by a large number of structures located in different geological environments. To maintain security and service conditions, satellite-based monitoring can play a key role, since it can cover large areas by accurately detecting ground displacements due to anthropic activities (underground excavation...

As space-based Earth observations are delivering a growing amount and variety of data, the potential of this information to better support disaster risk management is coming into increased scrutiny. Disaster risk management actions are commonly divided into the different steps of the disaster management cycle, which include: prevention, to minimize...

On November 11, 2019, a Mw 4.9 earthquake hit the region close to Montelimar (lower Rhône Valley, France), on the eastern margin of the Massif Central close to the external part of the Alps. Occuring in a moderate seismicity area, this earthquake is remarkable for its very shallow focal depth (between 1 and 3 km), its magnitude, and the moderate to...

The main active tectonic structure in the western part of Central Sulawesi (Indonesia) is the left-lateral Palu-Koro strike-slip fault. Its offshore section was thought not to have broken during the M w 7.5 Palu Earthquake on 28 September 2018, challenging the established knowledge of the tectonic setting at this location. Here, we use Sentinel-1 S...

Subsidence phenomena have been observed and confirmed for several decades in the broader coastal area of Sindos-Kalohori, located at the west of the city of Thessaloniki, Greece. The area is part of a 2500-year old plain, occupying about 2000 square kilometers that are drained by four rivers, two of which form extensive deltas. The reasons for the...

The broader area of Athens, a region exhibiting relatively low crustal deformation, was stroke in 1999 by a catastrophic earthquake posing serious questions regarding strain accumulation in slow deforming regions located within active geodynamic regimes. In the present study, the establishment of a dense geodetic network, primarily designed to moni...

Volcanic history of Santorini over recent years records a seismo-volcanic unrest in 2011–12 with a non-eruptive behavior. The volcano deformation state following the unrest was investigated through multi-sensor Synthetic Aperture Radar Interferometry (InSAR) time series. We focused on the analysis of Copernicus Sentinel-1, Radarsat-2 and TerraSAR-X...

The strong M7.3 November 12 2017 earthquake at the border region of Iraq‐Iran activated a massive landslide near Mela Kabod village, Iran. The Mela Kabod landslide was the most significant secondary effect of the 2017 earthquake and of considerable importance, due to its size, for the study and documentation of earthquake environmental effects. Usi...

At the beginning of 2011 Santorini volcano underwent a volcanic unrest, accompanied by an increase of the microseismic activity. The unrest that lasted for over a year, demonstrated substantial amounts of uplift, justifying the volcanic origin of the activity. The continuation of the deformation monitoring after the unrest event was deemed necessar...

In many arid planar regions of the world, ground subsidence induced by the lowering of the water table line due to pumping has recently caused damage to houses and other overlying structures. The depth of the water table lowering is usually tens of meters, the depth of the underlying soil layers may be hundreds of meters, and the region where the l...
