“…Assuming the 484/508 CE earthquake indeed occurred on the Fucino fault, the Mw 6.5, 30 October 2016 earthquake (5 intensity degree EMS‐98 in Rome; Rossi et al, ) can be interpreted as a modern twin of the 443 CE event. This interpretation is in agreement with that in Galli et al (), concluding that the penultimate earthquake on the VBFS occurred in Late Roman times, perhaps in 443 CE.…”

22‐kyr‐Long Record of Surface Faulting Along the Source of the 30 October 2016 Earthquake (Central Apennines, Italy), From Integrated Paleoseismic Data Sets

We integrate paleoseismic data sets along the Mt. Vettore‐Mt. Bove normal fault system rupturing at the surface in the 30 October 2016 Norcia earthquake. Through the analysis of new trenches from this work and a review of the preexisting data, we correlate events among trench sites along antithetic and synthetic fault splays. We recognize seven M 6.5, 2016 Norcia‐type (or larger) surface‐faulting events in the last ~22 kyr, including 2016. Before 2016, one event occurred in the past two millennia (260–575 CE) and possibly corresponds to the event damaging Rome in 443 or 484/508 CE. Three previous events occurred between 10590 and 415 BCE, whereas the two oldest ones date between 19820 and 16540 BCE. The average recurrence time is 3,360–3,640 years for the last ~22 kyr and 1,220–1,970 years for the last ~4 kyr. We infer a minimum dip‐slip rate of 0.26–0.38 mm/year on the master fault in the central portion of the Mt. Vettore–Mt. Bove normal fault system and a dip‐slip rate of at least 0.10 mm/year on the southernmost portion. We infer a Middle–Late Pleistocene inception of the long‐term scarp of the investigated splays. The along‐strike variation of slip rates well reproduces the trend of the 2016 surface slip; thus, the time window exposed in the trenches is representative for the present fault activity. Based on trenching data, different earthquake rupture scenarios should be also considered for local hazard assessment.

“…However, since there are no physical models capable of fully describing this phenomenon, the comparison between qualitative and quantitative measures of the severity of the seismic ground shaking are commonly carried out empirically. However, several authors observed that such empirical relationships between macroseismic observation and instrumental measures of the ground shaking do not always have an good statistical correlation (Ritchter 1958;Ambraseys 1975;Decanini et al 1995;Yih-Min et al 2003;Fujimoto and Midorikawa 2005). The main issue relates to their high variability and is essentially due to the different spatial representativeness of the two ground shaking measures: the instrumental one is restricted to few hundreds of meters in the vicinity of the recording station and strongly depends on local site effects; on the other hand, the macroseismic observations that contribute to assigning to a locality an intensity level is carried out on an extended inhabited area (even several square kilometres), often placed on a composite substrate with different geological, geomorphological, and topographic characteristics (Trifunac and Westermo 1977;Trifunac and Lee 1992;Theodulis and Papazachos 1992).…”

The relation between macroseismic intensity and ground shaking makes it possible to transform instrumental Ground Motion Parameters (GMPs) in macroseismic intensity and vice versa, and is therefore useful for making comparisons between estimates of seismic hazard determined in terms of GMPs and macroseismic intensity, and for other engineering and seismological applications. Empirical relationships between macroseismic intensity and different recorded GMPs for the Italian territory are presented in this paper. The coefficients are calibrated using a dataset of horizontal geometrical mean GMPs, i.e. peak ground acceleration, peak ground velocity, spectral acceleration at 0.2, 0.3, 1.0 and 2.0 s from the ITalian ACcelerometric Archive (ITACA; Luzi et al. in Italian Accelerometric Archive v3.0, Istituto Nazionale di Geofisica e Vulcanologia, Dipartimento della Protezione Civile Nazionale, 2019.

“…These earthquakes have greatly affected the population, economy, environment, and the society as a whole (Figure 3a-c). Older historic buildings of inestimable heritage value were especially affected [10]- [13]. For example, the province of Emilia Romagna, for which a considerably lower seismic hazard is predicted compared to Zagreb, suffered 27 fatalities and heavy damage to 1,200 residential and 600 industrial buildings in two consecutive M5.7 and M5.8 earthquakes.…”

Seismic risk reduction in Croatia: mitigating the challenges and grasping the opportunities

Croatia is located in a seismically active region of Southern Europe. Disastrous earthquakes have occurred in the past and can hit again and, if not adequately addressed, losses to life and property can be significant. Yet, there is still not enough community awareness and understanding of the potential seismic risk, although it is indispensable for successful mitigation strategies. This paper discusses the current state of knowledge and practice related to seismic risk assessment and reduction activities in the country, and gives suggestions on how to effectively overcome challenges and seize the opportunities to increase community resilience.
