“…High seismicity of the SE Altai is evidenced by paleoruptures, numerous large Holocene earthquake induced landslides, and seismic convolutions in soft sediments (Fig. 2) (Butvilovsky, 1993;Rogozhin and Platonova, 2002;Rogozhin et al, 2007;Deev et al, 2009and Agatova et al, 2006, 2014a. Recently it was supported by the 2003 Chuya earthquake (M S =7.3).…”

“…This strongest historical seismic event generated a complicated NW trending system of primary seismotectonic deformations of about 70 km in length. Main rupture is a dextral strike slip fault with a horizontal displacement up to 2 m, and subsidiary branch faults of reverse and dextral strike slip kinematics (Rogozhin et al, 2007). Landslide on the right Taldura river bank is the largest seismogravitational deformation triggered by this earthquake (Fig.…”

This paper presents the results of paleoseismogeological investigations including tree-ring analysis and radiocarbon dating in pleistoseist zone of the 2003 Chuya earthquake, SE Altai, Russia. Twenty-five radiocarbon dates of previously unknown evidences of prehistoric earthquakes along the fault bounders of the Chagan-Uzun massif, North Chuya and South Chuya ranges are reported. Perspectives of applying dendroseismological approach within the high mountainous seismically active southeastern part of Russian Altai are demonstrated. In addition to estimating the germination ages of trees growing on the bare surfaces of seismically triggered landslides, analysis of wood penetrating injuries in the individual tree ring series was applied for dating paleorock-falls. Analysis of distribution patterns of tree-ring anomalies and injured trees suggests a criterion of recognizing seismic origin of past rock-falls. Dendrochronologically obtained dates of abrupt intensifications of rock-falls can be considered as supposed dates of past earthquakes, which should be verified by alternative proxy data. Obtained results argue for the high regional seismicity in the second half of the Holocene. Strong earthquakes occurred here AD 1532, and 600-700, 1300-1500, 2400-2700, 3400-3700, 3800-4200 cal BP. This data clarifies the chronology of seismic events within the SE Altai. The specified recurrence interval of strong earthquakes is about 400 years during the last 4000 years.

“…Rukavičková and Hanžl (2008) concluded that rock-mass dislocation caused by an earthquake may be a factor that triggers fluid migration but there are other natural processes to consider: exogenetic events such as floods or landslides causing rapid strain increase in rocks, or sudden changes in piezometric pressure in aquifers, which result in the ejection of diluted sandy-clayey material to the ground surface. The description of the physical features of the mud volcanoes found in NW Gobi and Altay (Mongolia), which formed as a result of earthquakes and other exogenetic phenomena, (Rukavičková andHanžl 2008 andRogozhin et al 2007), is similar to the mud volcanoes found in the Upper Benue Trough of Nigeria.…”

“…In other countries such as India (Chaudhuri et al 2012; http://mudvolcanoes.weebly.com/baratang-island-mudvolcano-india.html), Venezuela (Aslan et al 2001;Duerto, McClay 2002), Trinidad and Tobago (Knight et al 2002), Mongolia (Rukavičková, Hanžl 2008) Brought and USA (California), (Rudolph, Manga 2010) there are onshore mud volcanoes substantially similar to those discovered in Nigeria in terms of their height, shape, size and mud flow from the crater. The scientific discussion regarding the origin of mud volcanoes is concerned mainly with the following categories: (a) mud volcanoes sensu stricto, linked with hydrocarbon gas release, (b) hydrothermal mud volcanoes, (c) mud volcanoes as a manifestation of an earthquake or a sudden exogenetic event (Pitt and Hutchinson 1982;Dimitrov 2002;Rogozhin et al 2007fide: Rukavičková, Hanžl 2008. The Nigerian onshore mud volcanoes, based on their sizes, heights, and geological nature, indicate they originated as a result of an earthquake or sudden exogenetic events as proposed by Rukavičková and Hanžl (2008).…”

Onshore mud volcanoes are rare geological phenomena, which in Nigeria were reported for the first time few years ago in the Upper Benue Trough. In this study a detail geological mapping of the area of mud volcanoes occurrence was carried out, with the primary aim of defining their relationship, if any, to the structural geology there. The systematic field reconnaissance included field observations of the structural features, as well as analysis of the location and distribution of the onshore mud volcanoes, marking their locations on the topographic and geological maps, analysis of the aerial photographs and satellite images. The study area covered the central part of the Upper Benue Trough where the onshore mud volcanoes were found. The study area is the part of a sedimentary basin comprising Cretaceous clastic rocks that have been deformed intensively by a network of faults often embedded in the underlying Precambrian basement. This network of faults underwent a rejuvenation period from the Aptian to the Palaeocene. The most prominent tectonic structure in the study area is the NE -SW trending Kaltungo Fault Zone, however, there are other minor faults with N -S and NW -SE trends. This study shows that the mud volcanoes found in the study area are usually located near or within fault zones, within the outcropping Upper Cretaceous Yolde Formation and Upper Bima Sandstone, both of which were deformed by the Kaltungo faults, as well as by other minor faults.Worldwide, incidences of onshore mud volcano formation are usually attributed to areas of tectonic activity, rapid sedimentation or hydrocarbon occurrence. In this study, the interpretation of the field observations and mapping results, combined with information on the structural evolution of the study area and seismic pattern (very scarce), have led to the conclusion that the location of onshore mud volcanoes in the Upper Benue Trough, being located along the fault zones, is structurally controlled. The close relationship between mud volcano location and the structural framework of the area may be interpreted as one of several possible subsurface geological responses to present tectonic activity.
