The separation between the mobile plate (Phanerozoic) in south and west of the eastern European Precambrian East European Craton is the most prominent geological limit in Europe known as the Trans-European Suture Zone (TESZ) In this study we were mainly interested in a prominent segment of TESZ, known as the Tornquist -Teisseyre Area (TTZ). In this study we highlighted the TTZ area through the gradient of geoid from Romania. The geoid provides a good representation of the long wavelength characteristics of the Ear...

Space weather can be monitored from the ground (astronomic/astrophysics observations and geomagnetic observatories) and from space (satellite data). Optical instruments (telescopes on the ground) recording the number of sun spots, as well as to viewing aurora, but these observations are affected by the weather from Earth's atmosphere. Observation from space does not have such a limitation. In the last years,satellites and spacecraft have monitoring the space weather. Through cooperationbetween European Space Agenc...
