Studying satellite radar data from ESA's Envisat and the Italian Space Agency's COSMO-SkyMed, scientists have begun analysing the movement of Earth during and after the earthquake that struck on 6 April 2009.
Last week's powerful earthquake in the central Italian Abruzzo regional capital L'Aquila has unearthed prehistoric dwellings there. Some of the vaulted caves measure up to five metres in height, according to Italian geologist Gianluca Ferretti.
"We are exploring them" - Gianluca Ferretti, who teaches geology at L'Aquila's university.
Studying satellite radar data from ESA's Envisat and the Italian Space Agency's COSMO-SkyMed, scientists have begun analysing the movement of Earth during and after the 6.3 earthquake that shook the medieval town of L'Aquila in central Italy on 6 April 2009. Scientists from Italy's Istituto per il Rilevamento Elettromagnetico dell' Ambiente (IREA-CNR) and the Istituto Nazionale di Geofisica e Vulcanologia (INGV) are studying Synthetic Aperture Radar (SAR) data from these satellites to map surface deformations after the earthquake and the numerous aftershocks that have followed.
At least 50 people are dead and 50,000 homeless in an earthquake which has flattened parts of central Italy. Prime Minister Silvio Berlusconi has declared a state of emergency for the central Abruzzo region where the quake struck.

At least 40 people have been killed in a powerful earthquake that struck central Italy, Italian officials say. Five children are said to be among the dead and many remain unaccounted for as a massive search for the trapped is under way. The 6.3-magnitude quake struck at 0330 (0130 GMT) close to L'Aquila city, 95km north-east of Rome.
A strong magnitude 5.4 earthquake occurred at 21:57:45 (UTC) on Wednesday, December 17, 2008, in the southern Italy region, 65 km West of Cosenza, at a depth of 260.7 km. Location 39.291°N, 15.485°E
