<p>In the earth and planetary sciences, the term "analog experiment" indicates laboratory experiments that use analog materials to investigate natural processes. Scaled experiments constitute a representative sub-category of analog experiments. They are designed to have the same dominant dimensionless parameter in the same range as the targeted natural processes. Other primary uses of analog experiments are education and outreach. Reproducing similar phenomena in front of the audience is useful in explaining the essence of the complex dynamics of natural processes. However, it is often the case that we do not fully understand the physics of the experimental systems or the targeted natural phenomena. In such cases, especially when the process is complex, it is difficult to guarantee the scaling similarity. When we take such laboratory phenomena as a research subject of earth science, we encounter critical comments about the scaling issue.</p><p>Nevertheless, I think it scientifically important to consider questions like follows. What is the mechanism of the experimental phenomena? Why the behaviors of the experiment look similar to the natural phenomena? To what extent the laboratory and the natural systems are similar. To indicate experimental studies to elucidate these questions, I would like to define "analogy experiment" as a new sub-category of analog experiments.  Some recent experiments are presented as examples.</p>

This paper addresses recent growth within thes caleand kind of Earth science knowledge has provided new opportunities to massive knowledge analytics analysis for understanding the Earth's physical processes. There has been associate upsurge of natural science datasets within the past few decades that are being frequently collected mistreatment various modes of acquisition, at deferent scales of observation, and in numerous knowledge sorts and formats. Earth science knowledge sets but exhibit some distinctive characteristics (e.g. adherence to physical properties and spatiotemporal constraints), that gift challengestoancientdata-centric approaches.In this paper the comparative study of Hadoop’s programming paradigm (Map reduce)andHadoop’s ecosystems Hive and Pig.The processing time of map reduce, hive and pig is implement edona data set with simple queries. It is observed that Map reduce processes the datain shorter time ascompared with Map reduceand Hive. It is not necessary that only Map Reduce is useful other techniques are also useful under differentconstraints.

Iceland is one of the most recognizable and iconic places on Earth, offering an unparalleled chance to admire the most powerful natural phenomena related to the combination of geodynamic, tectonic and magmatic forces, such as active rifting, volcanic eruptions and subvolcanic intrusions. We have identified and selected 25 geosites from the Snæfellsnes Peninsula and the Northern Volcanic Zone, areas where most of the above phenomena can be admired as they unfold before the viewers’ eyes. We have qualitatively assessed the selected volcano–tectonic geosites by applying a set of criteria derived from previous studies and illustrated them through field photographs, unmanned aerial vehicle (UAV)-captured images and 3-D models. Finally, we have discussed and compared the different options and advantages provided by such visualization techniques and proposed a novel, cutting-edge approach to geoheritage promotion and popularization, based on interactive, navigable Virtual Outcrops made available online.

Always actual tasks of obtaining and processing experimental results in complex systems. Random obstacles (errors), measurement errors, imperfections and limitations of mathematical models and data processing algorithms can change the appearance of the distribution and lead to incorrect use of algorithms, for example, as is the case with Kalman filtering in control systems. Complex methods for the identification of distribution laws require the study of quantum systems, natural phenomena, environmental, biological, etc. processes, which are characterized by the presence of singularities and multimodality of distributions. Therefore, it is often not recommended to apply separate distribution laws to simulate probabilistic experimental data distributions, but a generalized distribution as a single statistical system, which known distributions include as individual partial cases. Thus, the generalized gamma distribution includes Rayleigh, Maxwell, Weibull, Levy, Hi-Square distributions, which are widely used in applied problems associated with statistical methods of physical processes research, remote sensing, in the theory of reliability, for describing the dispersion composition of particles fragmentation and calculation of the efficiency of phase separation in gas-liquid streams.

<p>The teaching learning of Earth science, particularly the Italian schools, where the research has been developed in the last ten years, has highlighted a widespread lack of knowledge among students, which corresponds to a lack of sensitivity in the common thought towards geological and environmental issues, to its territory, moreover often characterized by widespread disruption phenomena and natural hazards.</p><p> As a consequence, too often the culture of geosciences is understood as a culture of emergencies and not of prevention. It is a priority to promote a widespread culture of natural hazards, the knowledge of natural phenomena, the danger inherent in the geological evolution of the territory, the responsible use of the environment, the perception of phenomenon as part of the dynamics of the Earth. This research presents a path,  defined with disciplinary objectives and specific skills to be developed and monitored, with the aim  to contribute in spreading a greater awareness of the dangers derived from natural phenomena. The training of students must pass through more effective methodological and educational approaches, active teaching, inquiry and investigation, promoting competences and skills. Since it is experienced that the usual transmissive approach of this content is not proving effective, a PBL approach was experimented. The different steps are to raise awareness of the  territory in which one lives, through a geological and historical analysis of the context, the understanding of the natural and inevitable evolution of the territory, the speed and frequency with can occur, the surface that can be affected by different natural phenomena and the transformations into risks factors. Finally, awareness that their knowledge is the basis for preventing and vulnerable contexts is needed.</p><p>The research has highlighted the need of new and more effectives educational tools and paths, that has product a widespread awareness towards the need of a repertory of practical activities. These applied, investigative and hands-on activities have shown growth of skills and competences in the involved students. The double result of a greater awareness of environmental dynamics and risks and of greater skills, technical, such as knowing how recognize relationships, and of citizenship, seem to have been achieved.</p><p>The  experience has also discoved new needs: the development of a unique and more consistent  epistemology of the discipline,  that is capable of giving links and coherence to phenomena, materials and processes, closely interconnected, but too often not recognized as a disciplinary unicum.</p>

Abstract We developed the model, and carried out its discussion at the PIRT-2021 conference, within the framework of the research topic “External Forcing on Volcanoes and Volcanic Processes: Observations, Analysis and Implications” announced by the journal “Frontiers in Earth Science” in October 2020. Besides other, external processes considered in this Research Topic included astronomical. In this study, in the category “Hypothesis and Theory”, we investigate how changes in the position of large bodies of the Solar system can cause natural phenomena, associated with the movement of free masses, such as volcanism, earthquakes and landslides in the lithosphere, as well as various catastrophic events in the atmosphere and hydrosphere. The analysis has shown that the discovered phenomena of celestial bodies’ alignments accompanying manifestations of natural phenomena require going beyond the standard cosmological model and clarify the fundamental mechanism of gravity. We propose the novel Bidirectional Pushing Gravitation model (BPG), which, in addition to application in Earth Sciences, may occur useful in Astrophysics, Cosmology and Gravitation research.

The paper presented the evaluation of oil spill simulation backward in time with some input data conditions at South China Sea in Vietnam such as the environment factors (from simple to complex conditions) and oil spills (from one to multifarious). Oil spill processes are computed simulations such as physical processes and weathering processes and the oil properties change. The results of research and development for oil spill simulation backward in time are considered và determined with oil spill on sea that are consistent with hypotheses and natural phenomena such as reversing the direction of divergence, increased concentration backward in time, especially with an remarkable concentration area. It determines the ability to trace emission source in space and time under each corresponding input condition. Besides, this study may still not be optimized so they will continue to be solved in the future.
