“…The occurrence of tropospheric ozone variance depends on many environmental factors (e.g. dust storms [42], volcanic eruptions [43], etc. ), thereby the previous monitoring of tropospheric ozone is based on comparative analysis of long time-series data [44][45][46].…”

The attention towards links of atmospheric parameter variation and earthquakes has increased exponentially by utilizing new methods and more accurate observations. Persistent research makes it possible to gain insight into the precursor mechanism of earthquakes. In this paper, we studied the universality of detecting atmospheric anomalies associated with earthquakes based on tidal force fluctuation in China for earthquakes of Ms > 6.0, and explored the influence of tidal force on tectonic stress. The data of air temperature, geopotential height, ozone mixing ratio, and relative humidity from the National Center for Environmental Prediction (NCEP) were analyzed to reveal the spatiotemporal variation of atmospheric anomalies at multiple isobaric surfaces. Furthermore, the coupling of atmospheric parameters was investigated. The results showed that continuous solicitation exerted by tidal forces could change the strength of tectonic stress that causes earthquakes. The evolution pattern of air temperature, geopotential height, and relative humidity could be supported by atmospheric thermal vertical diffusion, while the anomalies of ozone mixing ratio was not evident. This verified the feasibility of detecting multi-parameter atmospheric anomalies associated with earthquakes based on tidal force fluctuation. Our results provide more evidence for understanding the atmospheric precursor characteristics of earthquakes.

“…It should be noted that atmospheric parameters are influenced by many external factors. Strong meteorological phenomena, geological activities, and disasters can lead to significant variation of atmospheric parameters [42,43,48,49]. The air temperature at the top isobaric surface in Nima rises again in part of the time.…”

“…Ozone (O3) is one of the most important trace gases in the atmosphere, and the stratosphere is considered as home of the ozone. Changes in the total ozone column (TOC) have been observed globally which are associated with seasonal changes, dust storms [30], tropospheric-stratospheric exchanges, weather disturbances, volcanic eruptions [31], atmospheric disturbances and cyclone/hurricanes. Lasukov [32] proposed ozone production associated with the rock deformation and fracture growth as the electromagnetic wave propagates from the hypocentral region to ionosphere, the anomalous electromagnetic signals reflecting changes in ionosphere provide a potential early warning signal about an impending earthquake.…”

The Index of Ozone Anomaly (IOA) has been proposed to detect changes in tropospheric ozone associated with strong earthquakes. The tropospheric ozone prior and after the 2008 Wenchuan earthquake has been analyzed using IOA. AIRS ozone volume mixing ratio (O3 VMR) at different pressure levels (600, 500, 400, 300, 200 hPa) for an 18-year period 2003-2020 has been considered to identify the unique behavior associated with the strong earthquakes. Our results show distinct enhancement in tropospheric ozone occurred on 5-day (7 May 2008) prior to the main event and distributed along the Longmenshan fault zone. An enhancement in IOA has also been observed around the time of the 2013 Lushan and 2017 Jiuzhaigou earthquakes, but with the different emergence time, which indicates that the unusual behavior of tropospheric ozone depends on the tectonic and geological environment, focal mechanism, focal depth, meteorological conditions and other factors. The location of increased tropospheric ozone indicates the epicenter of earthquakes. The magnitude of earthquake could be one of the important factors affecting the appearance of the anomalous tropospheric ozone. The possible mechanism for the increased tropospheric ozone associated with strong earthquakes is discussed in this paper. The quasi-synchronous changes of tropospheric ozone and other parameters in the lithosphere/ atmosphere/ ionosphere have been found by combining with the other published results related to the Wenchuan earthquake, which show the existence of coupling during the earthquake preparation phase associated with the Lithosphere-Atmosphere-Ionosphere coupling (LAIC).

“…A large amount of volcanic ash was dispersed by winds in a different direction. The north-east wind at 500 meters altitude and the south-to-south-westerly wind at 5000 and 10,000 meters bring the volcanic ash towards different directions [6].…”

Volcanoes are a kind of geological feature which can bring both destruction and wealth to human beings. This study takes the eruption of Taal Volcano on January 12, 2020 as an example to analyze its eruption evolution, causes and influence factors via QGIS software. Taal Volcano lies at the southwestern end of a convergent boundary between the Eurasian and Philippine Sea tectonic plates where volcanic activities are frequent. Results show that the evolution of the eruption consists of increased CO2 flux, seismic swarms, phreatic explosion chronically. The origin of the volcano is the subduction of the oceanic plate and terrestrial plate. Volcanic eruptions are mostly due to pressurization by active convergent plates activities. The eruption emitted tephra and gas, which exerted impacts on the atmosphere, the nearby vegetation and the water body, and was predicted to result in an El Nino. High concentration of particles, dispersed tephra output, a sharp increase in SO2 and CO content, variation in atmospheric ozone, and rise in humidity were observed in the atmosphere following the eruption. The volcanic output wiped out the plant cover on the volcano island, and covered the vegetation outside of the volcano island, as shown in the RGB band composite and land cover change monitoring images generated using QGIS from Sentinel-2 data. The volcanic output’s influences on nearby water bodies were shown through drops in ocean salinity and Taal lake’s PH, variation in ocean temperature, and increased ocean’s surface latent heat flux.
