In order to do this, we make a manual review of the continuous data recorded by the PASSEQ seismic stations in Lithuania. Therefore, the aim of this paper is to find any natural tectonic seismic events in Lithuania and to obtain more general view of seismicity in the region. This data can be used to answer the question of whether there exist seismically active tectonic zones in Lithuania that could be potentially hazardous for critical industrial facilities. The stations recorded a number of local and regional seismic events originating from Lithuania and adjacent areas. Twenty-six seismic stations of the PASSEQ temporary seismic array were installed in the territory of Lithuania. A new opportunity to study seismicity in the region is provided by the PASSEQ (Pasive Seismic Experiment) project that aimed to study the lithosphere–asthenosphere structure around the Trans-European Suture Zone. Two recent earthquakes with magnitudes of more than 5 in the Kaliningrad District (Russian Federation) on 21 September 2004 motivated re-evaluation of the seismic hazard in Lithuania and adjacent territories. Ganas et al.The territory of Lithuania and adjacent areas of the East European Craton have always been considered a region of low seismicity. Presentation on the March 2021 earthquakes in Thessaly, Greece by A.The sequence raises numerous questions related to fault interactions, blind faulting, near- and far-field ground motions, damage distribution, earthquake triggering, liquefaction phenomena and seismic hazard and seismotectonics of the Northern Thessaly. Remote-sensing imagery is available from a number of satellites and other platforms. This was the most significant earthquake sequence in northern Thessaly in 80 years, and the first large events in this area of Greece since the major upgrades of the seismological, strong motion and geodetic networks. This sequence included a M6.3 mainshock on March 3, followed 32 hours later by a M6.0 event and a M5.6 event on March 12, and thousands of smaller aftershocks. The Bulletin of the Geological Society of Greece (BGSG) is inviting papers for a Special Issue on the 2021 Northern Thessaly, Greece, Earthquake Sequence. | Christoph Grützner in Earthquake, Paper Call for papers: Special Issue on the 2021 Northern Thessaly, Greece, earthquake sequence.If I’ll get that 1 million €, you’ll hear more on re-ruptures from me □ These ideas are at the core of a project I’m writing right now, called REDEFINE: “RE” stands for re-rupture and Task 1.1.3 will be the update of the probability curves of Figure 2b – no more spoiler on the project! In turn, this may affect the computation of key parameters for seismic hazard assessment, such as recurrence interval, slip per event and elapsed time. This has strong implications for paleoseismology, because it is virtually impossible to identify events occurring few months or years apart. So, I checked the USGS catalogue, looking for earthquakes with M > 6, depth 6, z 6 earthquakes onshore include the repeated rupture of the same fault strand(s). In the last 5 years, at least 2 other cases of repeated rupture in a short time interval were observed, i.e., the 2016 Kumamoto (Japan) and 2019 Ridgecrest (US) sequences.įault re-ruptures are currently not accounted for in seismic hazard assessment should paleoseismology folks care about re-ruptures? To answer this question, it is necessary to understand how common re-ruptures are. This event is particularly interesting because its surface rupture overprinted the faulting occurred only 3 months earlier, on August 24. ![]() | Francesca Ferrario in Earthquake, Opinion | one responseįive years ago, on October 30, 2016, a Mw 6.5 earthquake nucleated along the Vettore Fault in Central Italy.
