“…On the other hand, peculiar features, recognized in many caves worldwide, have been often linked to earthquake damages (e.g., Postpischl et al, 1991;Ferranti et al, 1997;Lemeille et al, 1999;Delaby, 2001;Forti, 2001;Kagan et al, 2005;Šebela, 2008;Panno et al, 2009;Bábek et al, 2015;Méjean et al, 2015), although specific paleoearthquakes identified in caves have been rarely constrained by independent data outside caves (Becker et al, 2005). The speleotectonic analysis conducted in this study within the Cavallone Cave (in the most external portion of the Central Apennines) allowed for recognizing a mid-Holocene paleoearthquake and finding robust correlations with independent on-fault and off-fault data in surrounding areas.…”

“…This evidence includes broken speleothems and fallen stalactites (e.g., Postpischl et al, 1991;Ferranti et al, 1997;Lemeille et al, 1999;Delaby, 2001;Kagan et al, 2005;Šebela, 2008;Panno et al, 2009;Bábek et al, 2015;Méjean et al, 2015), blocks and ceiling collapses (e.g., Gilli, 1999;Pérez-López et al, 2009), deformed cave sediments and fault displacements (e.g., Gilli et al, 2010;Bábek et al, 2015), and speleothem growth anomalies (e.g., Forti et al, 1981;Forti and Postpischl, 1984;Akgöz and Eren, 2015;Rajendran et al, 2015). Although direct observations of cave damages immediately after an earthquake have rarely been observed, "seismothems" (i.e., speleothems potentially broken, or deformed, by a seismic…”

“…Another piece of evidence of earthquake-induced phenomena is the presence of specific spatial distribution patterns of fallen concretions, resting on sub-horizontal or slightly inclined cave ground. Collapsed stalagmites toward preferential orientations may be consistent with the strike of the earthquake source (e.g., Gilli et al, 1999;Ferranti et al, 2015) or its slip direction (e.g., Méjean et al, 2015). More suitable for this kind of observations are fallen stalagmites cemented on the floor to ensure that broken speleothems have maintained their original direction in time (Forti, 2001).…”

Abstract. A speleoseismological study has been conducted in the Cavallone Cave, located in the easternmost carbonate sector of the Central Apennines (Maiella Massif), in a seismically active region interposed between the post-orogenic extensional domain, to the west, and the contractional one, to the east. The occurrence of active "silent normal faults", to the west, close to blind thrusts, to the east, raises critical questions about the seismic hazard for this transitional zone. Large collapses of cave ceilings, fractures, broken speleothems with new re-growing stalagmites on their top, preferential orientation of fallen stalagmites and the absence of thin and long concretions have been observed in many portions of the karst conduit. This may indicate that the cave suffered sudden deformation events likely linked to the occurrence of past strong earthquakes. Radiocarbon dating and, above all, the robust correspondence with other coeval on-fault and off-fault geological data collected in surrounding areas outside the cave, provide important constraints for the individuation of a mid-Holocene paleoearthquake around 4.6-4.8 kyr BP. On the basis of the available paleoseismological data, possible seismogenic sources can be identified with the Sulmona normal fault and other active normal fault segments along its southern prosecution, which recorded synchronous strong paleoevents. Although the correlation between speleotectonic observations and quantitative modeling is disputed, studies on possible effects of earthquake on karstic landforms and features, when corroborated by independent data collected outside caves, can provide a useful contribution in discovering past earthquakes.

This work presents the results of the speleological study developed in the Ecce Homo Cerro Cave located in the southwest of the central subregion of the Cesar department, in the Colombian Caribbean region, associated with carbonated rocks of the Aguas Blancas Formation belonging to the Cogollo Group, which have suffered Chemical and mechanical dissolution generating endocárstico and exocárstico environments. In the cavern were found different types of pavillian, paving and zenith speleothems of different sizes in the galleries, being this the tourist attraction of such cavity, such as columns, moonmilk, stalactites, castings, sawtooth, gours and flags. Lithologically, this geological unit is constituted by gray, biomicritic and dismicríticas limestones with high fossiliferous content, intercalations of shales, recrystallized sediments with calcium carbonate, pellets and shells recrystallized with calcium carbonate. The Ecce Homo Cerro Cave can be catalogued as a punctual Geosite with geomorphological interest, taking into account the large number and variety of speleothems presented as well as its excellent state of preservation.

“…The seismotectonic framework of the Central-Northern Apennines is complicated by the occurrence of re-verse and strike-slip events delineating an active contractional domain along the peri-Adriatic foredeep-foreland sector that exhibits a moderate and less frequent seismicity with respect to the western extensional one and for which paleoseismological and seismological data are very scarce (Fig. 1; e.g., Frepoli and Amato, 1997;Pondrelli et al, 2006;Montone et al, 2012).…”

Abstract. A speleoseismological study has been conducted in the Cavallone Cave, located in the easternmost carbonate sector of the Central Apennines (Maiella Massif), in a seismically active region interposed between the post-orogenic extensional domain, to the west, and the compressional one, to the east. The occurrence of active ''silent normal faults'', to the west, close to blind thrust, to the east, raises critical questions about the identification of the true seismogenic sources for this transitional zone. Large ceiling collapses, fractures, broken speleothems with new re-growing stalagmites on their top, preferential orientation of fallen stalagmites and absence of thin and long concretions have been observed in many portions of the conduit and may indicate that the cave suffered of sudden and catastrophic events likely linked to the occurrence of past strong earthquakes. Although controversies exist about the correlation between speleotectonic observations and quantitative modeling, speleotectonic studies, when corroborated by independent data collected outside caves, can play a fundamental role in discovering past earthquakes. Radiocarbon dating and, above all, the surprisingly correspondence with other coeval paleoseismological and geological data collected in surrounding areas outside the cave, provide important constraints for the individuation of a Mid-Holocene paleoearthquake around 4770 ± 30 yr BP and for the identification of the Sulmona normal fault as the most likely causative structure.
