Earthquake prediction in tectonic active areas using space techniques

Ziel

To develop a new integrated monitoring technique to analyse the
tectonic, seismological and geological behaviour of the
Sannio-Matese area and to identify the precursory earthquake
phenomena. New space techniques, GPS and Differential
Interferometric Synthetic Aperture Radar, will be developed to
integrate the classic techniques of ground deformation
measurements and the traditional methods for earthquake
prediction such as high precision levelling, tilt monitoring and
seismic network. The data-set will be used to determine a 3-D
seismotectonic model of the test area.


The capability of Differential GPS measurements to detect small movements will be verified
by means of a GPS network of 16 stations, which is planned in Situ. During five in Situ
campaigns, the horizontal and vertical components of displacement will be measured.
The potentiality of Differential SAR Interferometric technique to identify and to measure the
small height variations of observed area will be verified by means of 20 (10 pairs) corner
reflectors placed in a grid along lines approximatively orthogonal to SAR spaceborne track.
The data collected with space technique will be integrated with the data-set of seismic
network and modern means for ground deformation measurements like levelling and
tiltmeters.

At present time the Sannio-Matese area is monitored by a seismic network of five telemetric
seismographs, three out of which are 3-component stations, of the Vesuvian Observatory and
by three seismic stations of the ING (National Institute of Geophysics, Rome) operating in
the area. The existing network will be reinforced with five additional 3-component seismic
stations. With this number of stations it will be possible to detect low-magnitude events and
at the same time to determine accurately epicentres which are substantial factors to define the
earthquake sources as well as to draw stress field maps based on focal mechanisms.

High precision levelling will provide the vertical component of ground deformation. A
levelling network crossing the chain from Caianello to Campobasso has been planned: this
will be formed by 60 benchmarks spaced at about 1 km for a total length of about 60 km.
Two in Situ levelling campaigns will be carried out.
The tilt monitoring will be used to measure with continuity the crustal movements. Two
complete digital tiltmeter systems will be installed in the test area.

The data acquired with the different techniques will be processed and compared to validate
the effectiveness of space techniques in detecting small movements. Subsequently, the data
collected will be integrated with historical seismic data of the test-site to define a
seismotectonic 3-D model.
The seismotectonic model together with the observed parameters will be used to verify the
feasibility of an observation Network for monitoring precursory phenomena and for
predicting earthquakes.
