    Local and duration magnitude determination for the Italian Earthquake Catalog, 1981-2002 (2007)
    The Seismological Society of America
    Details
    Publication Date: 2017-04-04
    Description: In the present work, we update magnitude estimates of the instrumental catalogue of 99,780 Italian earthquakes that occurred during 1981-2002. The catalogue contains a large data set of P and S arrival times and accurate earthquake locations. We derive duration magnitude estimates from linear regression between local magnitude calculated from Mediterranean Very Broadband Seismographic Network (Med Net) and the corresponding seismic signal durations at the national network (RSNC). We introduce a station correction factor Scj because of most of the stations located in southern Italy show large residuals that appear to be of regional importance. The relation obtained: Mdij= 2.49•log (Tij) – 2.31+ Scj. Log MO - ML and MW - ML relations are also computed in the range of 3.5 - 5.8 from regional centroid moment tensor estimation of medium-strong Italian earthquakes, by linear regressions. We obtained best least square fits for: LogMo = 1.18(±0.06)•ML + 10.92 Mw = 0.79(±0.4)•ML + 1.20

    Evidence of seismic deformation of the paved floor of the decumanus at Tindari (NE, Sicily) (2008)
    Blackwell Publishing Ltd
    Details
    Publication Date: 2017-04-04
    Description: Most of the ancient town of Tindari (NE, Sicily) was settled on a plateau the most surficial layer of which was made of unconsolidated material. Ongoing excavations at the archaeological site at Tindari uncovered a large portion of the decumanus which suffered deformations preliminarily assigned to coseismic effects. An analysis of the local dynamic response through the simulation of strong seismic shaking to the bedrock and modelling of spectral ratios of the bedrock-soft soil was carried out to verify the susceptibility of superficial terrains of the promontory to coseismic deformations. To perform this simulation the finite element method (FEM) was used. Four accelerometric recordings of three earthquakes of medium-high magnitude, recorded on rocky sites, were chosen to simulate the seismic shaking, using a constitutive law for the materials composing the promontory layers both of linear-elastic type and of elastoplastic type. The analysis of the linear-elastic field allowed the definition of the frequencies for which the spectral ratios of the accelerations recorded the highest amplifications; in particular the frequency range 31.5–37.2 Hz can be combined with deformation of the paved floor of the decumanus. The analysis in the elastoplastic field highlighted the zones of promontory more susceptible to suffer plasticization process. The results show that the topmost layer of the decumanus is the most susceptible to suffer plasticization. Therefore, the performed analysis lends greater support to the hypothesis that the deformations were produced by seismic shaking.

    The 20 and 27 April 1894 (Locris, Central Greece) Earthquake Sources through Coeval Records on Macroseismic Effects (2005)
    The Seismological Society of America
    Details
    Publication Date: 2020-03-24
    Description: Newly retrieved coeval records on the effects of the two large earthquakes of 20 and 27 April 1894 in Locris (central Greece) have been analyzed to assess macroseismic intensities according to the European Macroseismic Scale (Grünthal, 1998). An intensity equal or higher than 8 has been estimated at 70 different places. The two earthquakes were close in time and both focused on the same area; this asked for an interpretation free, as much as possible, from the prejudice due to the accumulative descriptions implied, for instance, by the 1894 scientists' reports. To image the earthquake sources and derive the main seismic parameters, we processed the macroseismic intensity data by using the Boxer method proposed by Gasperini et al. (1999). On the basis of this approach and our new sets of data, we obtain M 6.4 and 6.5 for the 20 and 27 April earthquakes, respectively, the latter being substantially smaller than the estimates proposed in previous works. Results obtained from the processing of macroseismic data have been tested and compared to recent geological data. Our preferred interpretation is that the 20 and 27 April 1894 earthquakes ruptured together the whole Atalanti fault. The internal structural complexity of the Atalanti fault appears to have controlled the rupture propagation: the change in strike of the fault trace along with its intersection with the Malesina fault, near Proskinas, is interpreted as a geometric barrier that is the boundary between the two individual earthquake sources. The 20 April earthquake would have ruptured between Proskinas and Skroponeri Mountain, southeast of the village of Larimna, whereas the 27 April earthquake ruptured between Proskinas and the northwest Chlomon fault zone, north of the town of Atalanti.

    Design and function of superfast muscles : new insights into the physiology of skeletal muscle (2005)
    Annual Reviews
    Details
    Publication Date: 2022-05-25
    Description: First published online as a Review in Advance on October 24, 2005. (Some corrections may occur before final publication online and in print)
    Description: Author Posting. © Annual Reviews, 2005. This article is posted here by permission of Annual Reviews for personal use, not for redistribution. The definitive version was published in Annual Review of Physiology 68 (2006): 22.1-22.29, doi:10.1146/annurev.physiol.68.040104.105418.
    Description: Superfast muscles of vertebrates power sound production. The fastest, the swimbladder muscle of toadfish, generates mechanical power at frequencies in excess of 200 Hz. To operate at these frequencies, the speed of relaxation has had to increase approximately 50-fold. This increase is accomplished by modifications of three kinetic traits: (a) a fast calcium transient due to extremely high concentration of sarcoplasmic reticulum (SR)-Ca2+ pumps and parvalbumin, (b) fast off-rate of Ca2+ from troponin C due to an alteration in troponin, and (c) fast cross-bridge detachment rate constant (g, 50 times faster than that in rabbit fast-twitch muscle) due to an alteration in myosin. Although these three modifications permit swimbladder muscle to generate mechanical work at high frequencies (where locomotor muscles cannot), it comes with a cost: The high g causes a large reduction in attached force-generating cross-bridges, making the swimbladder incapable of powering low-frequency locomotory movements. Hence the locomotory and sound-producing muscles have mutually exclusive designs.
    Description: This work was made possible by support from NIH grants AR38404 and AR46125 as well as the University of Pennsylvania Research Foundation.
