Our planet Earth is a dynamic system in which endogenous and exogenous processes permanently change the terrestrial physiognomy, contribute to the mobility and redistribution of chemical elements, transform terrestrial ecosystems (with their respective effects on natural selection), and ensure the permanent interaction between rocks, soil, life, hydrosphere, and atmosphere. All this gives rise to the complex planetary homeostasis that our world has experienced, especially in its most recent evolutionary history.

Due to the enormous importance of these complex interactions mentioned above, necessary for the correct understanding of the evolutionary history of our planetary home, it is essential to continue deepening both in the methods of study and in the knowledge itself of endogenous and exogenous processes, the latter materialized in natural phenomena (past and present), which manifest themselves in a particular way according to their corresponding spatio-temporal scale.

In the context of the above mentioned, this issue of the Geology Bulletin brings to its readers a variety of research papers covering topics related to processes related to both exogenous and endogenous processes, as well as topics related to methodological contributions that are key to ensuring the robustness of geoscientific data.

Among the articles published here, we present topics such as: (1) the formation and evolution of diapirs and mud volcanoes present in the Colombian Caribbean, which is a study that has great implications in hydrocarbon exploration; (2) the retreat shown by the Nevado del Cocuy glacier, which is a process that deserves special attention for being an important water resource; (3) the study of agglutinated benthic foraminifera in sedimentary rocks of the San Cayetano Formation (outcropping unit in northern Colombia), which is important to interpret its depositional environment, among other implications; (4) the implementation of models to assess susceptibility, hazard and risk of mass movements, which is fundamental to better understand landslide processes; (5) seismicity and seismotectonic associated with the Algeciras Fault System (Eastern Cordillera of Colombia), fundamental to better understand the seismic hazard in this region of the Colombian territory; (6) the application of non-seismic and non-conventional methods to support geological and geophysical studies used in hydrocarbon exploration in the Central Basin of Cuba; (7) the implementation of predictive deconvolution, homomorphic phase inversion and extended Kalman filter algorithms, key to obtain seismic reflectivity profiles, thus offering a great opportunity to compare the reliability of data obtained by other methods; and finally, (8) a review of microscopic techniques for digital rock models, which are key in exploration and exploitation studies of oil and gas, especially unconventional reservoirs, is presented. Finally, we invite all those interested in the scientific papers published in the different issues of the Geology Journal, to consult and download the articles they require, through the web page:
