“…The changes in electric field can also generate thermal radiation as the observed quasisynchronous increase in some temperature-related parameters in the case of Wenchuan earthquake, i.e., MBT (Microwave brightness temperature) [1,2], SKT (Skin temperature) [8], AT (Air temperature) [8], DTR (Diurnal temperature range) [8], OLR (Outgoing longwave radiation) [27] (see Table I). Coseismic responses of groundwater level and temperature have also been observed [7,68]. (2) Increased ozone precursors around the time of earthquake occurrence.…”

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).

“…2). Such changes have been particularly well observed in hydrogeologic systems 140 , with sudden variations in streamflow 141,142 , groundwater level [143][144][145][146][147] , temperature [148][149][150] and seismically triggered mud volcanism 6,60,[151][152][153] . With increased permeability, regions of higher and lower pressures may become connected, allowing fluid flow and pore pressure redistribution 59,63 .…”

It is generally accepted that tectonic earthquakes may trigger volcanic activity, although the underlying mechanisms are poorly constrained. Here, we review current knowledge, and introduce a novel framework to help characterize earthquake-triggering processes. This framework outlines three parameters observable at volcanoes, namely magma viscosity, open- or closed-system degassing and the presence or absence of an active hydrothermal system. Our classification illustrates that most types of volcanoes may be seismically-triggered, though require different combinations of volcanic and seismic conditions, and triggering is unlikely unless the system is primed for eruption. Seismically-triggered unrest is more common, and particularly associated with hydrothermal systems.

“…A large amount of TEC profiles around the epicenter from 0000 to 1200 UT provide evidence of continental earthquake-induced vertical oscillations that lasted in the ionosphere for several hours. He and Singh (2019) analyzed water temperature data in continental China from the boreholes equipped with water temperature sensors, and found that nearly half of the boreholes show a coseismic response associated with the Wenchuan earthquake. They explained the mechanism of the coseismic groundwater temperature response with enhanced fluid flow induced by an earthquake.…”

During May 12-14, 2018, the International Conference for the Decade Memory of the Wenchuan Earthquake, in connection to the 4th International Conference on Continental Earthquakes (4th ICCE) and the 12th General Assembly of the Asian Seismological Commission (ASC), was held in Chengdu, China. There have been several outcomes of the Conference (for example, the book published jointly by Higher Education Press and Springer) as well as the present special issue. Among the 58 submissions, 34 have been accepted after peer review. Some of the papers came from the presentations during the Conference, but with additional submissions, the scope of this special issue is far beyond that of the proceedings of the meeting.
