The fingerprint of earthquakes identified with satellite interferometry

Posted by fidest press agency su venerdì, 21 Maggio 2021

From the analysis of satellite images, the areas with the greatest seismic intensity of an earthquake are recognized. Through the images obtained by means of satellite interferometry technique, a team of researchers from the Sapienza University of Rome and the Istituto Nazionale di Geofisica e Vulcanologia (INGV) analyzed the “fingerprint” of earthquakes through the recognition of the ground deformation that accompanies a seismic event. Scientists, in fact, have been able to estimate its dimensions and recognize the area where the most violent shaking accompanying earthquakes are concentrated. The study “The epicentral fingerprint of earthquakes marks the coseismically activated crustal volume” has just been published in ‘Earth Science Reviews’. The InSAR (Interferometric Synthetic Aperture Radar) data allow to detect the coseismic deformation (that is, the instantaneous and permanent deformation caused by the earthquake) delimiting the epicentral area where the greatest displacement is concentrated, through the analysis of the deformation of the ground around the fault activated during an earthquake. “Since 1993, with the images given by InSAR, a long list of seismic events has been analyzed; this list is always growing thanks to the increase in the number of satellites and to the improvement of the quality of SAR sensors and InSAR techniques in continental areas”, the researchers Patrizio Petricca (Sapienza University) and Christian Bignami (INGV) state. “With them it is possible to detect the coseismic deformation, delimiting the epicentral area where most of the displacement is concentrated. Outside this area, apart from phenomena of local amplification, the ground displacement decreases, resulting in the attenuation of the seismic shaking”. “Knowing these Earth manifestations helps to focus more specifically on seismic prevention in future epicentral areas, helping to calibrate the assessment of seismic hazard in which vertical movement plays a relevant role in increasing greater horizontal shaking and therefore greater damage. Earthquakes will return: on average, in Italy about 20 destructive earthquakes are generated per century”, concludes President Carlo Doglioni. font: The epicentral fingerprint of earthquakes marks the coseismically activated crustal volume” Patrizio Petricca, Christian Bignami, Carlo Doglioni (2021).

Parliament gives green light to visa-free travel for Moldovan citizens

Posted by fidest press agency su sabato, 1 marzo 2014

moldovaMoldovan citizens will soon be able to travel to the EU’s border-free Schengen area without a visa, under a draft law approved by Parliament on Thursday and already informally agreed with the Council. Moldova is the first Eastern Partnership country to meet all the requirements for visa-free travel laid down in the Visa Liberalisation Action Plan.
The 2001 visa regulation lists non-EU countries whose nationals need a visa to travel to the Schengen area (the “negative list”) and those whose nationals do not need a visa for this purpose (the “positive list”).This update, approved by 460 votes in favour, 40 against and 10 abstentions, transfers Moldova from the negative to the positive list. Moldovans who have biometric passports (with a chip storing the holder’s facial image and fingerprints) would be able to travel to the Schengen area for 90 days within a 180-day period.”Today is a very significant day not only for the EU visa policy as such, but particularly for the Republic of Moldova. I am very pleased that the Parliament passed with such overwhelming majority the decision to abolish visas for the citizens of Republic of Moldova”, said rapporteur Tanja Fajon (S&D, SL).”Visa free regime is one of the most concrete elements of the relations with the EU and one of the most tangible measures, particularly important for the people, especially the young. Moldova is turning a new leaf. The government should continue with its European journey and I warmly welcome future efforts to be made in this regard”, she added.
After Parliament’s approval, the Council is expected to formally endorse the amended regulation no later than in April, subject to the check of the lawyer linguists. “The visa-free regime for Moldovan citizens should then be applicable before summer”, says Ms Fajon.Moldovan citizens already benefit from a visa-facilitation agreement with the EU in force since January 2008 (an upgraded agreement took effect in July 2013). According to the Commission, the number of short-stay Schengen visa applications from Moldovan citizens has remained stable over the past three years (oscillating between 50 000 and 55 000). Also, many of them already hold a Romanian passport.Moldova lifted the visa requirement for EU citizens on 1 January 2007.
