    Testing of a Prototype Tsunami Early Warning System for the Coasts of Italy (2010)
    Details
    Publication Date: 2020-10-22
    Description: In the framework of the agreement between Italian Civil Protection and INGV (DPC-S3 project), we are studying the feasibility of a Tsunami Early Warning System (TEWS) for the coasts of Italy. The performances of such a prototype TEWS have been evaluated. The underlying concept is borrowed from the Japan Meteorological Agency's TEWS. This tsunami warning system is in fact based on a set of elementary submarine earthquake sources. In case of an earthquake, the wave heights generated by each elementary source must be interpolated to evaluate in real-time if and where a significant tsunami could have been generated, in order to launch an alert for the most exposed coastlines. A series of synthetic tests have been conducted in order to assess the optimal resolution of the parameter's space sampling, and to construct a sufficiently accurate database of elementary sources. The results of the synthetic tests are presented here. Moreover, the Mw=6.9 May 2003 Boumerdes- Zemmouri (Algeria) earthquake, which generated a moderate tsunami causing significant damages particularly at Balearic Islands (Spain), has been used as a case-study for the validation of the database.

    Probabilistic Tsunami Hazard Analysis for Eastern Sicily (Italy) (2010)
    Details
    Publication Date: 2020-10-22
    Description: We applied the method for Probabilistic Tsunami Hazard Analysis (PTHA), first introduced by Rikitake and Aida (1988), to the coasts of eastern Sicily (Italy), and focusing on important cities such as Messina, Catania, and Augusta. The method has been very recently improved by Gonzàlez et al. (2009) to explicitly include inundation. Our approach considers both far- and near-field sources. Based on the approach described by Lorito et al. (2008), we identified a few Source Zones (SZ), each of which is characterized by a Typical Fault (TF) floating within it and capable of generating the Maximum Credible Earthquake (MCE). Some of the MCE recall historical events such as the 1908 Messina, the 1693 Catania and the 365 AD Crete earthquakes. We calculated the combined probability for all considered SZs by assigning a recurrence interval to each of them and a Poisson distribution of the inter-event times. We performed the PTHA for different damage metrics, such as runup, current speed, momentum and Froude number, with probability of exceedance of given thresholds being evaluated for different time intervals.

    Kinematics and Source Zone Properties of the 2004 Sumatra-Andaman Earthquake and Tsunami: Nonlinear Joint Inversion of Tide-Gage, Satellite Altimetry and GPS data (2010)
    American Geophysical Union
    Details
    Publication Date: 2017-04-04
    Description: We (re)analyzed the source of the 26 December 2004 Sumatra-Andaman earthquake and tsunami through a nonlinear joint inversion of an in-homogeneous dataset made up of tide-gages, satellite altimetry, and far-field GPS recordings. The purpose is two-fold: (1) the retrieval of the main kinematics rupture parameters (slip, rake, rupture velocity); (2) the inference of the rigidity of the source zone. We independently estimate the slip from tsunami data and the seismic moment from geodetic data, so to derive the rigidity. Our results confirm that the source of the 2004 Sumatra-Andaman earthquake has a complex geometry, constituted by three main slip patches, with slip peaking at ~30 meters in the Southern part of the source. The rake direction rotates counter-clockwise at North, according to the direction of convergence along the trench. The rupture velocity is higher in the deeper than in the shallower part of the source, consistently with the expected increase of rigidity with depth. It is also lower in the Northern part, consistently with known variations of the incoming plate properties and shear velocity. Our model features a rigidity (20-30 GPa), that is lower than PREM average for the seismogenic volume [Dziewonski and Anderson, 1981]. The source rigidity is one of the factors controlling the tsunamigenesis: for a given seismic moment, the lower the rigidity, the higher the induced seafloor displacement. The general consistence between our source model and previous studies supports the effectiveness of our approach to the joint inversion of geodetic and tsunami data for the rigidity estimation.

    Limited overlap between the seismic gap and coseismic slip of the great 2010 Chile earthquake (2011)
    Nature Publishing Group
    Details
    Publication Date: 2017-04-04
    Description: The MW 8.8 mega-thrust earthquake and tsunami that occurred on February 27, 2010, offshore Maule region, Chile, was not unexpected. A clearly identified seismic gap existed in an area where tectonic loading has been accumulating since the great 1835 earthquake experienced and described by Darwin during the voyage of the Beagle. Here we jointly invert tsunami and geodetic data (InSAR, GPS, land-level changes), to derive a robust model for the co-seismic slip distribution and induced co-seismic stress changes, and compare them to past earthquakes and the pre-seismic locking distribution. We aim to assess if the Maule earthquake has filled the Darwin gap, decreasing the probability of a future shock . We find that the main slip patch is located to the north of the gap, overlapping the rupture zone of the MW 8.0 1928 earthquake, and that a secondary concentration of slip occurred to the south; the Darwin gap was only partially filled and a zone of high pre-seismic locking remains unbroken. This observation is not consistent with the assumption that distributions of seismic rupture might be correlated with pre-seismic locking, potentially allowing the anticipation of slip distributions in seismic gaps. Moreover, increased stress on this unbroken patch might have increased the probability of another major to great earthquake there in the near future.

    Clues from joint inversion of tsunami and geodetic data of the 2011 Tohoku-oki earthquake (2013)
    Nature Publishing Group
    Details
    Publication Date: 2017-04-04
    Description: The 2011 Tohoku-oki (Mw 9.1) earthquake is so far the best-observed megathrust rupture, which allowed the collection of unprecedented offshore data. The joint inversion of tsunami waveforms (DART buoys, bottom pressure sensors, coastal wave gauges, and GPS-buoys) and static geodetic data (onshore GPS, seafloor displacements obtained by a GPS/acoustic combination technique), allows us to retrieve the slip distribution on a non-planar fault. We show that the inclusion of near-source data is necessary to image the details of slip pattern (maximum slip ,48 m, up to ,35 m close to the Japan trench), which generated the large and shallow seafloor coseismic deformations and the devastating inundation of the Japanese coast. We investigate the relation between the spatial distribution of previously inferred interseismic coupling and coseismic slip and we highlight the importance of seafloor geodetic measurements to constrain the interseismic coupling, which is one of the key-elements for long-term earthquake and tsunami hazard assessment.
