In the frame of European Commission project "Seismic Hazard Harmonization in Europe" (SHARE), aiming at harmonizing seismic hazard a scale, compilation homogeneous, parametric earthquake catalogue was planned. The goal to be achieved by considering most updated historical dataset and assessing homogenous magnitudes, with support from several institutions. This paper describes SHARE Earthquake Catalogue (SHEEC), which covers time window 1000–1899. It strongly relies on experience "Network...
Moment tensor inversion of early XX century mechanical seismograph recordings offers the opportunity to estimate source parameters for a number important earthquakes. This knowledge is crucial understanding regional tectonics and estimating seismic hazard; but processing historical seismograms often difficult. Especially, rotation horizontal into radial (P–SV) transverse (SH) components tends fail; example, if one polarity wrong, alignment not correct, or component lost. To avoid these kind...
The investigation of historical seismicity has increasingly demonstrated its pivotal role in advancing seismic hazard and risk assessment. This study presents an integrated methodological approach to recover analyze analog seismograms, aiming enhance our understanding earthquakes their implications for local regional seismotectonic modeling. Our work focuses on three events occurred southern Italy: the 1947 Squillace Basin earthquake, 1968 Belice sequence, 1978 Ferruzzano earthquake. These...
Abstract An accurate re-evaluation of the instrumental magnitude has been performed for 28 December 1908 Messina Straits earthquake (Southern Italy), one most destructive events ever recorded in Mediterranean region. Despite crucial importance this seismic hazard assessment, values reported literature show a wide range variability, reflecting inherent uncertainties typical early data. This variability suggests need rigorous revision data and methods used estimation. With purpose, we (1)...
We examine and model analogue recordings from 6 early mechanical seismographs for the 1910 June 16 earthquake at Adra, Southern Spain. Modern standard, time-domain analysis techniques were applied to historical data estimate source parameters of event: The regional sparse network inverted deviatoric seismic moment tensor. best tensor solution corresponds a M0= 1.50 · 1018 Nm, MW 6.1 oblique strike-slip event km depth. Our preferred faulting is: strike 122°, dip 80°, rake −137°, in very good...
Abstract On 26 January 1531, a strong‐magnitude earthquake heavily impacted Lisbon downtown. Immediately after the earthquake, eyewitnesses reported large waves in Tagus estuary, mainly north of city and along northern bank river. Descriptions include impacts on ships anchored estuary even morphological changes riverbed. We present synthesis available information concerning both water disturbance as basis for discussion probable tectonic source magnitude associated river oscillations....
Abstract. The M ∼ 8.3–8.4 25 November 1941 was one of the largest submarine strike-slip earthquakes ever recorded in Northeast (NE) Atlantic basin. This event occurred along Eurasia–Nubia plate boundary between Azores and Strait Gibraltar. After earthquake, tide stations NE a small tsunami with maximum amplitudes 40 cm peak to through Madeira islands. In this study, we present re-evaluation earthquake epicentre location using seismological data not included previous studies. We invert travel...
The Iberia-Maghreb region, made up of Spain, Portugal, Algeria, and Morocco as well the surrounding offshore areas in Atlantic Ocean Mediterranean Sea, is a complex plate boundary setting that displays important variations earthquake faulting stress patterns at regional local scales ( e.g. , Buforn et al. 2004; Stich 2006; Fernandez-Ibanez 2007; De Vicente 2008). inventory seismic moment tensors for region rapidly increasing network broadband stations becoming denser, small-to-moderate...
Studying a changing world requires observations going back in time to extend and contextualize our latest scientific knowledge. Old legacy data exist non-digital formats. Thus, techniques methodologies for the preservation, dissemination, interpretation, homogenization, calibration, use of such their associated metadata, as well present are important topics advancing understanding Earth past extreme events. The articles presented this special issue review different issues involved these...
Abstract The scientific community has become increasingly aware of the importance preserving and recovering historical seismic data, also because their possible use in combination with modern techniques analysis. Seismograms coming from analog recording era cover more than 100 yr activity may have a great relevance, especially for risk evaluations regions struck by destructive events past centuries but characterized minor last decades. In this study we used seismograms to investigate an...
Abstract The 10 July 1923 earthquake near Berdún (Spain) is the largest instrumentally recorded event in Pyrenees. We recover old analog seismograms and use 20 hand‐digitized waveforms for regional moment tensor inversion. estimate magnitude M w 5.4, centroid depth of 8 km, a pure normal faulting source with strike parallel to mountain chain (N292°E), dip 66° rake −88°. new mechanism fits into general predominance Pyrenees extension inferred from Global Positioning System data. unique...
We collected analog seismogram recordings and seismic bulletins for two moderate magnitude earthquakes in the province of Jaen, southern Spain, on 10 March 19 May 1951, series aftershocks. Seismograms from main events reveal striking similarity, pointing to nearby locations similar source mechanisms. This casts a shadow quality preserved phase readings macroseismic data, which suggests distance several tens kilometers between both mainshocks A critical review available permitted us detect...
<p>On 10th September 1919 several slightly damaging earthquakes struck the towns of Torremendo, Jacarilla (near Alicante, SE-Spain) and others nearby. Available magnitude estimations for largest two events series are M = 5 approx. They were moderate size they occurred in a region where similar earthquakes, thoroughly studied, recently (1999 Mula; 2002 Bullas; 2005 La Paca; 2011 Lorca). This makes these interest better definition regional seismicity. We study their sources from analysis...

Abstract. The M~8.3–8.4 25th November 1941 was one of the largest submarine strike-slip earthquakes ever recorded in North East (NE) Atlantic basin. This event occurred along Eurasia-Nubia plate boundary between Azores and Strait Gibraltar. After earthquake, tide stations NE a small tsunami with maximum amplitudes 40 cm peak to throw Madeira islands. In this study, we present re-evaluation earthquake epicentre location using seismological data not included previous studies. We invert travel...
Abstract We present the first estimates of moment tensor solutions and probabilistic nonlinear hypocenter locations for 1968 Belice earthquake sequence, which is most relevant seismic activity occurred in western Sicily historical times. This phase, including six earthquakes with magnitude between 5 6.4, produced severe damages fatalities a sector Nubia–Eurasia plate margin, previously considered aseismic. Poorly constrained often controversial focal mechanism available from literature have...
