The project called "Swarm for earthquake study (SAFE)" will study, based on data collected from satellites and from ground-based instruments, what happens during the phase preceding the great earthquakes, trying to identify any electromagnetic signals from space. The project is coordinated by the INGV and funded by the European Space Agency. Planetek Italia will also collaborate to the project.
SAFE is going to start on May 2, 2015, and will last 16 months.
"The project aims to study the preparatory phase of large earthquakes through the analysis of electromagnetic data from sensors onboard the three satellites of ESA Swarm constellation in order to better understand the physical mechanisms involved," says Angelo De Santis, research director of the INGV and coordinator of the study - In particular, the Safe project aims to study the coupling between the outer part of the solid Earth, the lithosphere, where the earthquakes occur, and the overlying fluid portion, the atmosphere, with the objective to capture the information exchanged between the two layers through the integration of the data acquired by the satellites Swarm with those collected by other satellites and measuredby ground-based stations"

The primary goal of the Swarm satellite mission is to measure the Earth's magnetic field. The newborn SAFE project (funded by ESA under the framework STSE Swarm+Innovation, 2014) aims at applying the new approach of geosystemics to the analysis of Swarm data for investigating the preparatory phase of earthquakes. The main objective is to explore the possible link between magnetic/ionospheric anomalies and large earthquakes analysing Swarm as well as ground-based data (seismic, magnetic, GNSS, etc.). This paper shows the state of the art in lithosphere-atmosphere-ionosphere coupling (LAIC) and the expected contribution of SAFE in the field.

Although magnetometers may be capable of picking up precursor signals in surface rocks, they have one major drawback: They must be located within 100 kilometers or so of the epicenter. That’s why Angelo de Santis, director of research at the National Institute of Geophysics and Volcanology in Rome, and others have turned to satellites to get a global view of what happens in the atmosphere before earthquakes. Through a new research initiative called SAFE (Swarm for earthquake study), de Santis and his colleagues will pair data from the European Space Agency’s Swarm satellites, launched in 2013, with those from traditional earthquake monitoring devices like seismometers and GPS stations.
Their goal, de Santis says, is first to understand the link between Earth’s crust and atmosphere. “If you understand the physics, you double the chances to make predictions,” he says. They will also study past earthquakes to identify any patterns that precede known ruptures, and then see whether those same patterns precede future earthquakes. Already, at the meeting, they reported finding ionospheric anomalies before the 2014 Iquique earthquake in Chile and the recent disaster in Nepal.

Satellite measurements such as those provided by the present ESA Swarm mission provide measurements of the geomagnetic field with unprecedented spatial resolution and homogeneous coverage, which are not available from Earth’s surface data. On the other hand, downward continuation of satellite data is affected by external magnetic field sources in the ionosphere. Within this context, land, ocean and near surface measurements are an essential complement of satellite data.

To pursue the SAFE Project objectives and in order to investigate ionospheric signatures of possible lithospheric origin, the geospace conditions have been carefully investigated by considering the following worldwide adopted geomagnetic indices: ap, AE and Dst. When these indices exceeded a given threshold, the anomalies detected from both ground based and in situ data are described as external forcing related, without fully excluding their possible LAIC origin. The results shown on the following data-sheets are then based on the above considerations.

A new study by Xiong et al. connects these losses of GPS signal to equatorial plasma irregularities (EPIs), which occur when the electron density in the ionosphere’s F region undergoes large, rapid changes. EPIs mostly occur close to Earth’s magnetic equator, which might explain why the loss of GPS signal to Swarm satellites also occurred most frequently when the satellites were at low latitudes.

Alexander Grayver, from ETH Zurich, said, “The Swarm and Champ satellites have allowed us to distinguish between the rigid ocean ‘lithosphere’ and the more pliable ‘asthenosphere’ underneath.”
The lithosphere is the rigid outer part of the earth, consisting of the crust and upper mantle, while the asthenosphere lies just below the lithosphere and is hotter and more fluid than the lithosphere.
“Effectively, ‘geo-electric sounding from space’, this result is a first for space exploration,” he continues.
“These new results are important for understanding plate tectonics, the theory of which argues that Earth’s lithosphere consists of rigid plates that glide on the hotter and less rigid asthenosphere that serves as a lubricant, enabling plate motion.”* Satellite tidal magnetic signals constrain oceanic lithosphere-asthenosphere boundary (Science Advances)

With the aim of making the best possible use of existing satellites, ESA and Canada have made a deal that turns Swarm into a four-satellite mission to shed even more light on space weather and features such as the aurora borealis.
In orbit since 2013, ESA’s three identical Swarm satellites have been returning a wealth of information about how our magnetic field is generated and how it protects us from dangerous electrically charged atomic particles in the solar wind.
Canada’s Cassiope satellite carries three instrument packages, one of which is e-POP. It delivers information on space weather which complements that provided by Swarm. Therefore, the mission teams began looking into how they could work together to make the most of the two missions.

Two missions are presently particularly interesting in this context: The TPM-supported Canadian e-POP payload on the CASSIOPE satellite, now also called "Swarm Echo", and the Chinese CSES satellite. But other satellite missions, like MMS, ICON, GOLD, and others could also be interesting.
Swarm DISC also plans to play an active role in the collaboration with the scientific team working on the Chinese CSES satellite (China Seismo-Electromagnetic Satellite), in particular regarding calibration of the magnetometer data and scientific exploitation of the data in combination with Swarm.
