The basin is filled with late fluvioterrestrial deposits up to 500 m thick. These plains formed from the post-orgenic collapse of the first extensional phase in the Late Miocene–Pliocene. The first trended NE–SW and the second phase trended N–S during the mid-Pleistocene that then activated the E–W and ENE–WSW striking faults in the region. The hills that surround the plains are with Alpine like formations of the Pelagonian, Pindos and Koziakas/Western Greece geotectonic units made up of mostly limestone and undated Molassic sediments. Leontari-Anavra Fault Zone The Leontari-Anavara Fault Zone (LAFZ) is the most active Quaternary fault zone of the Western Thessaly plain region. The fault zone consists of four linked segments; the Kedros, Leontari, Velesiotes and Thaumako; all dipping northward and arranged in an en echelon fashion trending ENE–WSW. These segments are about 5–7 km in length, with a combined length of 25 km. Continuing seismic activity along the fault even after the quake has led to the creation of a multiple-scarp footwall morphology, some observed near and on the Enipeas river.Papathanassiou George Valkaniotis Sotirios Pavlides Spyros 2007-01-01 Applying the INQUA scale to the Sofades 1954, Central Greece, earthquake https://www.researchgate.net/publication/260163864 40Field study of the southern Thessaly highly active fault zone. http://doczz.net/doc/7240252/field-study-of-the-southern-thessaly-highly-active-fault-... 2021-10-31 doczz.net It also produced later tremors, one of them being the 2021 Larissa earthquake that led to the death of one person and summoned severe damage to multiple villages and towns. The earthquake was also said to have been part of the episodic pattern of tremors that have been produced in the area over the years.Vallianatos Filippos Michas Georgios Hloupis George September 2021 Seismicity Patterns Prior to the Thessaly (Mw6.3) Strong Earthquake on 3 March 2021 in Terms of Multiresolution Wavelets and Natural Time Analysis Geosciences 11 9 379 10.3390/geosciences11090379 2021Geosc..11..379V free Another example is the 1957 Velestino earthquake which occurred in the same basin but far on the other side of the LAFZ. Despite that it bears similarities and characteristics to the 1954 Sofades event.Papazachos Giannis Papazachos Costas Skarlatoudis Andreas Kkallas Harris Lekkas Efthimios 2016-01-01 Modelling macroseismic observations for historical earthquakes: the cases of the M = 7.0, 1954 Sofades and M = 6.8, 1957 Velestino events (central Greece) https://doi.org/10.1007/s10950-015-9517-9 Journal of Seismology 20 1 151–165 10.1007/s10950-015-9517-9 2016JSeis..20..151P 129650530 1573-157X subscription The Enipeas, Domokos, Vouzi, Farsala and Narthaki faults constitute an E-W trending fault zone with similar characteristics and kinematics to those of the eastern part. More precisely, a dominant strike-slip striation corresponding to a dextral strike slip motion has been recognized along the fault to be super imposed by two oblique to dip-slip striations corresponding respectively to two normal reactivations. Earthquake The earthquake struck at around 16:00 local time, initially reported of having a magnitude of 6.7–6.8, with most sources saying it recorded as 7.0 in magnitude. The maximum Modified Mercalli intensity ranged from intensity IX (Violent) to X (Extreme). The largest possible foreshock that was recorded was an earthquake of 4.6 w, and the largest aftershock measured 5.8 w, with an intensity of VI (Strong) according to the United States Geological Survey.M 5.8 – 6 km SSE of Kallifóni, Greece https://earthquake.usgs.gov/earthquakes/eventpage/iscgem890614/executive live 2021-10-31 United States Geological Survey https://web.archive.org/web/20211031105619/https://earthquake.usgs.gov/earthquakes/eventpage/iscgem890614/executive 2021-10-31 Impact Damage was observed mostly in the Thessalian Plain, specifically in the prefectures of Karditsa, Larissa, Trikala, Phthiotis, Magnesia and Evritania. The villages of Paschalitsa, Neo Ikonio, Asimochori, Fyllo, Grammatiko and Othomaniko among others suffered severe to complete damage. The villages near the epicenter also suffered major affects such as liquefaction; this was possibly due to the soft sedimentary rocks that comprise the Thessalian plains and the large scale intensities recorded in the regions. Surface ruptures were produced, measuring 5 km in length at most, which also interrupted and disrupted a train line connecting villages and to other regions. Local transport networks were badly affected, with damage to rail and road infrastructure, damage or destroyed.Lekka F Σιδηροδρομικός σταθμός https://dimoskarditsas.gov.gr/building/sidirodromikos-stathmos/ Δήμος Καρδίτσας DETAK & City Museum of the Municipality of Karditsa 9 January 2025 el Overall records say the tremor caused $3.15 or 100 million Francs (1954 rate) in damage. About 28,000 structures and homes sustained damage, 6,599 of which were destroyed, while 22,074 structures were slightly to heavily damaged. 25−31 people died and 717 people were injured.Rothé J.
