- PublicationRestrictedThe 2nd century AD earthquake in central Italy: archaeoseismological data and seismotectonic implications(2009-08)
; ; ; ; ;Ceccaroni, E.; Soprintendenza per i Beni Archeologici dell’Abruzzo, Chieti, Italy ;Ameri, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Milano-Pavia, Milano, Italia ;Gomez Capera, A. A.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Milano-Pavia, Milano, Italia ;Galadini, F.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Milano-Pavia, Milano, Italia; ; ; Abstract The 2nd century AD earthquake in central Italy is only known by an epigraph that mentions restorations to a damaged weighing-house at the ancient locality of Pagus Interpromium. The available seismic catalogues report this event with the conventional date of 101 AD, a magnitude M aw of 6.3, and an epicentral location at the village of San Valentino in Abruzzo Citeriore, in the province of Pescara. In order to improve the knowledge of the damage pattern, we gathered all the archaeological data collected during modern excavations at sites located in the area, which were presumably struck by the earthquake. This information is mainly represented by (1) stratigraphic units due to the sudden collapse of buildings over still frequented floors; (2) stratigraphic units demonstrating restoration or re-building of edifices; (3) stratigraphic units formed as the result of the abandonment of sites or of their lack of frequentation for decades or centuries. Only stratigraphic evidence consistent with an earthquake occurrence during the 2nd century AD has been considered. The most recent archaeological material found in a collapsed unit is a coin of Antoninus Pius, dated at 147–148 AD. This may represent a post quem date very close to the occurrence of the earthquake. The gathered information, plus the stratigraphic data that excluded the earthquake occurrence at some sites, has allowed us to roughly delineate an area of possible damage, including the Sulmona Plain and surrounding areas. Comparisons between the possible 2nd century damage distribution and (i) the damage patterns of more recent historical events that have struck the investigated area, (ii) the distribution of virtual intensities obtained by simulating an earthquake having an epicenter in the Sulmona Plain and applying an intensity attenuation relationship and (iii) a shaking scenario obtained by modelling the activation of the major active fault of the Sulmona Plain area (the Mt. Morrone fault) have revealed consistency between the ancient earthquake and the activation of this fault. Since no other historical events can be attributed to this active fault, we conclude that the time that has elapsed since the last fault activation should be in the order of 1,850 years, i.e. a time span that is very close to the recurrence interval of Apennine seismogenic sources. Moreover, considering the fault length, the causative source may be responsible for earthquakes with M up to 6.6–6.7. The comparison between the presumed 2nd century damage and the shaking scenario suggests that the magnitude mentioned is consistent with the presumed effects of the ancient earthquake. Finally, considering that Sulmona (the most important town in the region investigated) is located in the middle of the Mt. Morrone fault hanging wall, we consider it as the probable epicentral area. Therefore, to summarise the information on the 2nd century AD earthquake, we can conclude that (i) it occurred shortly after 147–148 AD; (ii) a magnitude M w 6.6–6.7 can be attributed to it and (iii) the probable macroseismic epicentral area was Sulmona.359 32 - PublicationRestrictedConsolidated models for attenuation of macroseismic intensity.

; ; ;Salcedo-Hurtado, E.; Universidad del Valle (Cali, Colombia) ;Gomez Capera, A. A,; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Milano-Pavia, Milano, Italia; On October 18, 1743 a great earthquake hit in Colombian central region. This seismic event caused severe damage in Santa Fe de Bogota that since 1740 had just been reinstated again as the capital of the “Nuevo Reino de Granada”. The churches of “Monserrate” and “Guadalupe” were destroyed and other suffered heavy damage. Damages were extended in surrounding areas as the towns of Fómeque, Chia, Usaquén Cáqueza, among others. In these towns, the churches were destroyed, and subsidence phenomena were noted, large cracks, fissures and landslides that clogged roads and some rivers and caused the death several people and animals. Applying the 1998 European Macroseismic Scale (EMS- 98), in the present work reassessing the macroseismic intensity in each affected town. We present a new macroseismic map with 18 intensity data points. We have proposed as maximum intensity equal to VIII in Fómeque, Guachavita and Cáqueza. In Santa Fe de Bogota the instensity is VII. The Bakun and Wentworth (1997) method is applied, using the intensity data points obtained in the present study and macroseismic intensity attenuation relationship given by Gómez Capera and Salcedo Hurtado (2002), to estimate earthquake parameters to 1743 event. We have proposed a macroseismic magnitude that equals 6.30±0.35 and the epicenter location in (4.43N, 73.91W) between the townships of Cáqueza and Guachavita.595 32 - PublicationOpen AccessKahramanmaraş - Gaziantep Türkiye M7.7 Earthquake, 6 February 2023 (04:17 GMT+03:00) Large historical earthquakes of the earthquake-affected region: a preliminary report(2023-02-16)
; ; ; ; ; ; ; The region where the 2023 February 6 earthquakes took place is known to have been very active in the past; it is part of the contact between the Eurasian and the Arabic plate, an area where seismic activity was relatively low in the 20th century (Figure 1). It is a “border zone” also from the historical point of view; therefore, although many earthquakes are known to most earthquake catalogues and compilations, the relevant information is often rather poor and affected by chronological and place-names problems. As a consequence, earthquake parameters given in the catalogues are often based on a poor dataset; the situation is even more complicated by chronological issues and careless compilations, which lead to earthquake duplications. In the frame of a larger investigation effort underway (Sesetyan et al., 2020; Stucchi et al. 2022) we first considered the available information from the main earthquake catalogues and compilations in the time-window 1000-1900. The volume by Ambraseys (2009) summarizes and sometimes updates the knowledge already proposed in previous works such as Ambraseys and Jackson (1988), Ambraseys (1989), Ambraseys and Finkel (1995). We also considered the works by Soysal et al. (1981), Guidoboni et al. (2019), Sbeinati et al. (2005), some recent historical earthquake investigations and the parametric catalogues by Shebalin and Tatevossian (1997), Tan et al. (2008), Sesetyan et al. (2013). Next, we assessed - when possible - macroseismic intensities at the mentioned localities and, from them, we assessed earthquake parameters by making use of the so-called “Boxer” method by Gasperini et al. (1999). For some of the main earthquakes in the region we briefly summarise here the earthquake parameters from our investigation and from the main catalogues. In the Appendix we summarise the available information.426 525 - PublicationOpen AccessThe CERESIS earthquake catalogue and database of the Andean Region: background, characteristics and examples of use(2004)

R.; Centro Regional de Sismologia para América del Sur (CERESIS), Lima, Peru; ; ; ; The history of earthquakes in South America starts with the coming of the Spanish and Portuguese «conquistadores» at the beginning of the 16th century. Their chronicles, and those of local historians, are the only source of earthquake information for the following 400 years. The creation of the Regional Centre for Seismology for South America (CERESIS) was a major factor for homogenous regional progress, in that CERESIS promoted the implementation of the first unified earthquake catalogue and database for the whole Andean Region. This paper reviews basic information about the intensity database and the focal parameter catalogues proposed by CERESIS in 1985. Further macroseismic data available from the CERESIS database (earthquakes with I0 = 8) are used to obtain preliminary results for the earthquake source parameters of selected South American historical events. The case of the Great Earthquake of the Venezuelan Andes, 29 April 1894, is presented in some detail.265 2870 - PublicationRestrictedSCIENZAPERTA: EARTH SCIENCE FOR EVERYONE...

A number of events, conferences, seminars, guided tours through the Institute and its laboratories are every year offered to general public. The venue is held in most of the cities where the Institute is located, priority to high seismic and/or volcanic risk regions. On May 2014 we held ScienzAperta for the first time in Milano and open up the doors to schools specifically dealing mostly with seismic hazard in a region where general public not necessarily think it might We offered students conferences, seminars and educational activities to highlight the fun of science and jet raise awareness on proper behaviours in case of earthquake shaking. We asked students and teachers, from elementary to high schools, to fill in a questionnaire that we use to evaluate the appreciation the venue had. One hundred years after Giuseppe Mercalli’s death we could not forget to celebrate his science the city where he was born.447 61 - PublicationOpen AccessCalibrating the Bakun Wentworth's Method for the Macroseismic Estimation of Earthquake Parameters in Italy(2008-09-07)

The calibration is required as the method derives an intensity magnitude (equal in the mean to moment magnitude Mw) from macroseismic observations by using a regionally suitable attenuation relationship of intensity as a function of Mw and source distance. To this purpose, a training set of earthquakes occurred in Italy since 1980 was selected, for which a large number of intensity observations and reliable instrumental determinations of Mw and epicentral location are available. Following the Bakun-Wentworth’s method, the distribution of intensity data with epicentral distance was analyzed for each one of the events considered and three different functional relations (linear, logarithmic and cubic dependence on distance) were calibrated. We also considered two better constrained (defined on a much larger dataset) intensity attenuation relationships recently proposed for Italy, originally derived as a function of epicentral intensity I0 and, thus, “converted” through an empirical I0-Mw relation. Performance of all the above relationships was then checked both on the training set and on an independent set of recent Italian earthquakes.209 94 - PublicationOpen AccessApplication of the Bakun Wentworth's Method for the Macroseismic Estimation of Parameters of Italian Earthquakes(2008-09-07)

Seism. Soc. Am., 87, 1502-1521; hereinafter B&W) and calibrated with Italian data by Gomez Capera AA, D’Amico V, Meletti C (2008, Calibrating the Bakun-Wentworth’s method for the macroseismic estimation of earthquake parameters in Italy, this conference) was applied to the recently released macroseismic database of Italian earthquakes (DBMI07; http://emidius.mi.ingv.it/DBMI07). The database contains about 83000 intensity data points for 1430 earthquakes. In the time-interval 1900-2006, for the greater part of the earthquakes the instrumental determination (epicentral coordinates and magnitude) is available. Thus, the Bakun and Wentworth method (B&W) was applied to a large set of Italian earthquakes and the results compared with those obtained adopting the Boxer approach (Gasperini, P., Bernardini, F., Valensise, G., Boschi, E.,1999, Defining seismogenic sources from historical earthquake felt reports, Bull. Seismol. Soc. Am. 89, 94-110); epicentral determinations by both methods were then compared with the instrumental parameters.201 262 - PublicationOpen AccessFrom macroseismic intensity data to the earthquake parameters(2010-09-06)

A tool called MIDOP (Macroseismic Data Online Publisher) has been created: by simply choosing a list of earthquakes and their corresponding MDPs, a complete self-sustained website can be created, ready to be published on the web. It offers an intuitive control panel for maps and tables customisation and it offers the possibility to generate places seismic histories. No external data-sources are required while presenting maps and the resulting websites can be browsed also locally. A series of problems related to the AHEAD environment have been taken into account while designing the tool: 1) macroseismic intensity data standardisation of formats among European institutions, 2) support the growth of locally developed macroseismic data-centres and 3) help publishing the earthquake data on the web with a specifically designed web-mapping tool.The second task to be addressed was to process such amount of MDPs in order to obtain earthquake parameters (epicentral location and magnitude) according to available and published methods. Three parameterization methods were identified: Boxer, Bakun & Wentworth and MEEP, each coming with its Windows pre-compiled line command executable. The tool, called “Parametrizator”, is able to batch process the input MDPs and present the result on maps using MIDOP.207 497 - PublicationOpen AccessModifica del codice SeisRisk III per l’utilizzo con dati di intensità(2009-09-17T09:28:18Z)
