However, their trigger mechanism, especially for tectonic earthquakes, involves many variables, including, among others, the influence of the Sun. This study presents the collection and discussion of data from 2012 to 2023, which compares solar activity with the occurrence of potentially destructive earthquakes, of magnitude equal to or greater than M6, considered on a global scale. The most significant clue from the study is constituted by the flow of solar protons which, corresponding to significant increases, show a potential relationship between potentially destructive geophysical events. The spatio-temporal analysis of proton increases, based on the discussion of 1567 events, has shown to have a close relationship with seismic events, especially for those of magnitude M6+.

The values, of an electromagnetic nature, fall within the category of natural origin radio signals, distinct from anthropogenic frequencies. The comparison between the two classes of candidate seismic precursors, which have been tested for over ten years, confirmed the trend observed in other earthquakes during the preseismic phases, with the appearance of magnetic anomalies starting five days before the earthquake. While solar activity studies may indicate potential global scale events, the data recorded by the Radio Direction Finding Network does not provide information on the direction of the earthquake epicenter relative to the monitoring stations. The earthquake under study confirms the trend of candidate precursors in the preseismic phases of seismic events with a magnitude equal to or greater than M5.

These systems utilize high-resolution cameras and advanced algorithms to produce accurate and precise 3D models, which are essential for analyzing, documenting, and preserving cultural heritage. While there are various methods for creating 3D models, minimizing cost and time is a primary concern. This paper focuses on photogrammetry as an option for surface reconstruction that might be used to make 3D representations of transparent objects. The objective of the research is to investigate the feasibility of creating appropriate 3D models for surface reconstruction and units of transparent objects through photogrammetry, utilizing open-source photogrammetry algorithms.

This study considered whether there was a relationship between the UTC time of occurrence of these earthquakes and their number, to verify whether there were emerging relationships between these data and the identification of any precursory seismogenic phenomena. The analysis of the data has shown that a periodicity of the seismic occurrence can be hypothesized, at certain hours of the solar day.

At 14:23:00 UTC a medium energy earthquake of M4 occurred. .8, in the United States, in New Jersey, Whitehouse station, a few kilometers from New York. The data discussed in this research are the result of continuous 24/7 monitoring and were considered to verify whether the direction of arrival of the electromagnetic signals can be associated with the direction of the future epicentral area, despite the considerable distance between the Rome station and New York. In particular, during the monitoring, low frequencies were recorded with the azimuth coming from the future epicentral area, already ten days before the earthquake occurred. Similar frequencies appeared, respectively, nine and four days before the earthquake.

The primary event also resulted in a tsunami that overwhelmed the population and infrastructure. In this study, the natural electromagnetic spectrum is analyzed a few days before these earthquakes occurred, with the aim of investigating any electromagnetic signals as possible candidates for physical phenomena in the preparatory phases of earthquakes. The signals detected are characterized by very low frequencies, already noted during other potentially destructive earthquakes, and by RDF signals attributable to candidate pre-seismic signals.

However, the roots of AI research trace back to the 1950s, with incremental developments along the way. The real explosion of interest and practical applications took hold with the advent of big data, increased computational power, and improvements in machine learning algorithms, especially since the early 2010s. In 2023, the Radio Emissions Project experimented with AIs to enhance the computing capability and data analysis of seismic data related to the research on seismic precursors. This study aims to understand whether AIs are capable of producing useful information for the comprehension of seismogenic mechanisms and interpreting data to perform short-term predictions on Italian seismic activity.

Within this context, there are actual international networks of observatories capable of providing data on the detection of these luminous appearances. In Italy, one of the most active stations is the LTPA Observer Project, established in 2007, which is equipped to monitor the night sky daily and provide key data on astronomical recordings associated with the passage of meteoric bodies in orbit around the Sun, attracted by Earth's gravitational force. In this realm, the study of these events has led to the emergence of a new investigative technique associated with seismic prediction. The LTPA Observer Project and the Radio Emissions Project, two Italian scientific initiatives for studying visible atmospheric luminous phenomena and seismic precursors, have highlighted the need to understand if sometimes the observation of large fireballs can be associated with the occurrence of strong earthquakes, albeit in a temporal context. This study explores precisely this possibility, namely whether the appearance of large fireballs can be considered a new, previously unknown seismic precursor, and whether this meteoric activity could be linked to solar activity.

This study discusses the electromagnetic and solar signals that anticipated the strong earthquake. This earthquake was preceded by a series of electromagnetic signals recorded by the RDF network developed by the Radio Emissions Project in Italy and by peculiar solar activity that occurred in the days before the disastrous quake. The authors believe that there may be a relationship linking telluric activity with space weather, evidenced by electromagnetic signals detectable in the phases preceding the earthquake in a time window of about five days. The results of the experiment show that the data can be compared with other known cases in the scientific literature, in the context of a crustal diagnosis and seismic precursor candidates.

The data obtained from this study also highlighted a correlation between the magnitude of the recorded earthquakes and the extent of the observed protonic increase. To confirm this, in this study the authors will present the results obtained by analyzing seismic events
recorded in Mexico during two different periods: those recorded between September 19 and 22, 2022, and the one recorded on September 8, 2017.

The authors analyzed the characteristics of the solar ion flux in the hours and days that preceded this seismic sequence, finding an increase in the density of the solar wind that preceded the Turkish seismic sequence recorded on February 6, 2023. Furthermore, the analysis of the natural electromagnetic background through RDF (Radio Direction Finding) technology allowed the authors to detect pre-seismic radio emissions with an azimuth compatible with the Turkish seismic district.

This seismic event was preceded not only by electromagnetic emissions, but also by some variations produced by solar activity. In this study, the group of researchers intends to underline the importance of the presence of possible electromagnetic precursors and variations of the proton density measured in the space near planet Earth, which could predict the occurrence of earthquakes, in an innovative monitoring technique that could be used to understand whether an earthquake can be expected to occur in a given geographical area.

The technique is a combination of two methods of observing natural phenomena. The first method involves continuous monitoring of the electromagnetic signal observed at the epicenter of a future natural disaster. The second method, based on the signal trend analysis, predicts the moment of the expected natural event. The effectiveness of the methodology is demonstrated by the example of a retro predict of the Hunga-Tong volcano eruption, which confirmed the actual eruption date. Additionally, a prediction was made for the date of the future volcanic eruption.

The objective of the present study is, therefore, to analyze the interaction between the lithosphere, atmosphere, and ionosphere in order to propose, prospectively, a new hydro-climatic model to be applied not only in Italy, where this research was carried out. The study concerns some of the most intense Italian earthquakes starting from 1920, with the destructive event in Lunigiana, in North Western Apennines, until the recent earthquake swarm that hit the Emilia-Romagna region followed, as in the cases analyzed in this research, by strong atmospheric disturbances. The recurrence associating seismic events with atmospheric precipitation allows us to propose some hypotheses about the triggering mechanism. In tectonically stressed areas, during pre-seism...

In the same temporal context, an anomalous behavior of the Wood Pigeons was observed, which were not able to orient themselves autonomously to proceed in the S-SW direction towards the wintering areas mainly Corsica, Sardinia, the Iberian Peninsula, North Africa, after/ during the crossing of the Italian peninsula. Also in this case the anomalous behavior of these birds occurred a few days before the earthquake. In this study, the group of researchers verified all the data relating to the natural electromagnetic variation to understand if there is a clear relationship between the anomalous behavior of these migratory birds and the electromagnetic pre-seismic phenomenon.

For the first time in the history of volcanology, the forecast was made by two independent methods. The first method analyzed the nature of changes in electromagnetic emission in the environment surrounding the volcano, while the second method predicted the date of Etna's eruption based on a trend composed of regularly measured electromagnetic emission parameters.
