A new strong quake at 1:35 am with 4.8  magnitude  and epicenter in the province of Macerata, according to the National Institute of Geophysics and Volcanology surveys (INGV). The epicenter was between Pieve Torina, Fiordimonte and Pievebovigliana.  Another quake was felt mainly in Marche , where they would be more than 20 thousand displaced people, and in Umbria, but it was also felt in Rome.

Delrio: “For the earthquake from 4 to 7 billion a year”

The Minister intervened on the national TV RAI, Agorà show, about the costs of the earthquake.””It takes a lot of money on prevention because we haven’t been investing enough in the last 20 years. Some people estimate 100 billion “but” the work can be progressive 4-7 billion a year. “We have possible resources ” because we spend more than 4-5 billion a year to repair the hydro-geological instability, instead we have to spend to prevent it. Our State must be present with all  necessary resources.”

The earthquake deforms 600 square kilometers

The earthquakes that from 24 August they will upset the Apennines are also reshaping the landscape, with depressions concentrated in an area of 600 square kilometers. Within this area is the deepest depression, the 130 square kilometers area where the ground has sunk up to 70 centimeters. This is what defined the data analysis came from satellites, on which the researchers are at work at this time.

“This is the contribution of earthquakes to the construction of the Apennine landscapes,” said Stefano Salvi, National Institute of Geophysics and Volcanology (INGV), engaged in processing the data sent to Earth by radar satellite Sentinel 1, the Copernicus program run by the European Space Agency (ESA) and the European Commission.

The analysis of the satellite images

According to unconfirmed preliminary estimates, earth movements may affect a larger area, up to 1,100 square kilometers. satellite data, developed by the Italian Space Agency (ASI) and the Institute for Electromagnetic Sensing of the National Research Council (CNR-IREA), indicate that the area of Norcia has moved 30 cm to the West and could it has raised 12 centimeters, while that of Montegallo has moved about 40 centimeters to the east. in addition to the Sentinel data 1 the researchers are working on those of the Italian Cosmo-SkyMed constellation, Asi and Defense Ministry. Further information are expected in the next few hours from the Japanese radar satellite Alos 2.

The radar satellites

The radar satellites are particularly important because they can detect images in all weather and light conditions, so even through clouds and during the night. The idea is that “it is on the same fault system for earthquakes of August 24 and 26 and 30 October,” said seismologist Gianluca Valensise, INGV.

He said – “the peculiarity of this earthquake was unusual behavior, so the strongest quake came last.” The big question for the experts, is to understand why the strongest earthquake did not happen immediately. This is not because earthquakes have rules: seismologists know that they should never be surprised. “At the moment the most obvious answer is that the structure that has been activated on October 30 was not ready,” said Valensise. And it was a good, otherwise, “there would be – he observed – adverse consequences for the population.”
