“…The main science goal of the mission is to probe the interior of Mars through seismic, geodetic, and heat-flow measurements: The relevant experiments are SEIS (Seismic During the first 6 months of operations following the Wind and Thermal Shield (WTS) deployment, the InSight seismometers have shown this expected sensitivity to atmospheric phenomena, even during the 18:00-24:00 LMST when the wind generated signal is very small and wind is below the resolution of the wind sensors (Banfield et al, 2020;Lognonné et al, 2020). On Earth, seismic noise of environmental origin provides information both about the source of noise and the structure beneath the stations (see, e.g., Tanimoto et al, 2015). Although many techniques used in terrestrial studies, such as the extremely powerful micro-seismic noise tomography Shapiro and Campillo (2004), rely on seismic networks, a variety of methods work for single station and can thus be applied in the framework of InSight.…”

Subsurface Structure at the InSight Landing Site From Compliance Measurements by Seismic and Meteorological Experiments

et al. 2020

Measurements of ground compliance at the InSight landing site—describing the surface response to pressure loading—are obtained from seismic and meteorological data. Compliance observations show an increase with frequency indicating the presence of a stiffer rock layer beneath the exposed regolith. We performed a Markov chain Monte Carlo inversion to investigate the vertical profile of the elastic parameters down to 20 m below InSight. Compliance was inverted both freely and assuming prior knowledge of compaction in the regolith, and the limitations and strengths of the methods were assessed on the basis of theoretical considerations and synthetic tests. The inverted Young modulus exhibits an increase by a factor of 10–100 over the first 10–15 m, compatible with a structural discontinuity between 0.7 and 7 m. The proposed scheme can be used for joint inversion of other seismic, geological, or mechanical constraints to refine the resulting vertical section.

A Critical Review of Ground Based Observations of Earthquake Precursors

2021

View full text Add to dashboard Cite

We aim at giving a short review of the seismo-associated phenomena detected on ground that in recent years have been investigated as possible earthquake precursors. The paper comes together with a companion article–published on this same volume by Picozza et al., 2021–devoted to summarize the space-based observation of earthquake–precursors by satellites missions. In the present work, we give an overview of the observations carried out on ground in order to identify earthquake precursors by distinguishing them from the large background constituted by both natural non-seismic and artificial sources. We start discussing the measurements of mechanical parameters and variations of geochemical fluids detected before earthquakes; then we review thermal and atmospheric oscillations; finally, observations of electromagnetic and ionospheric parameters possibly related to the occurrence of impeding earthquakes are discussed. In order to introduce a so large field of research, we focus only on some main case studies and statistical analyses together with the main hypotheses and models proposed in literature in order to explain the observed phenomenology.

“…Основні відмінності результатів для окремих іоносферних станцій стосуються деякої відмінності часу появи максимуму f0F2 поблизу нульової дати у західній і східній півкулях, що можна пов'язати як з особливостями прояву іоносферних збурень на різних геомагнітних широтах, так і впливом на іоносферу процесів у тропосфері, де екстремуми P також не збігаються. І дані про f0F2 у різних півкулях, і тим більше дані про глобальний ПЕВ вказують на те, що цей ефект носить загальнопланетарний характер і вимагає для свого пояснення інших механізмів, ніж розглядаються в багатьох роботах (див., наприклад, [1][2][3][4]).…”

Manifestation of global seismic activity in the atmosphere and ionosphere

Background. In recent decades, the concept of earthquakes (EQ) has been formed as the final stage of a planetary continuous self-organizing process with periods of accumulation and relaxation of tectonic stresses. However, in the scientific literature, as before, studies of the response of atmospheric and ionospheric processes to individual strong EQs are presented. In this work, the coupling of processes in the lithosphere, troposphere and ionosphere is considered for the first time, taking into account new ideas about the seismic process against the background of processes caused by space weather, which is a new step in the study of the human environment. Objectives of the work is to find relationships in the Earth – atmosphere – ionosphere – magnetosphere system on a planetary scale with a change in global seismic activity (GSA). Materials and methods. The studies were carried out using four daily databases for 2007–2015 on space weather and the magnetosphere (solar and geomagnetic activity indices), the ionosphere (f0F2 is the critical frequency of the F2 region in the western and eastern hemispheres; TEC is the global ionospheric total electron content), the surface atmosphere (atmospheric pressure) and the lithosphere (maximum EQ amplitude per day). The method of superimposed epochs and other statistical methods of analysis were used. Results. Quasi-synchronous changes in magnetospheric, ionospheric, and tropospheric characteristics have been established during periods of a sharp increase in GSA. They often have a cyclical sawtooth character from one seismically active period to another, which indicates the possibility of continuous interaction of geospheres, and not only during periods of disturbances. In particular, an increase in f0F2 with a sharp increase in GSA by up to 0.5 MHz was found almost simultaneously in the eastern and western hemispheres. Conclusions. The results obtained indicate the possibility of long-term or continuous interaction of the lithosphere with the geospheres located above. Space weather changes can be one of the sources of synchronization. As a possible mechanism for the appearance of global effects in the atmosphere and ionosphere when the GSA changes, it is proposed to consider the role of the release of deep gases to the surface. This process is global and is associated simultaneously with both seismicity and the parameters of the Earth's rotation.
