From the very early years on this Planet, earthquakes have always captivated people’s attention. The feeling of admiration and fear always lies within us, especially drawing on the most recent megathrust earthquake that hit the south coast of Kamchatka’s Peninsula, in Russia, twice this year. Therefore, in this week’s blog, we aim to explore how this phenomenon evolved and why this specific region ...[Read More]

How do earthquakes nucleate? How do they arrest? Can we predict or control them? How do fault zone structure and rheology influence rupture? What do earthquakes in the lab tell us? How does fluid injection modulate seismicity? The Institut des Etudes Scientifiques de Cargèse (IESC) premise in Corsica, France was abuzz with discussions about these and many other related questions this October. The ...[Read More]

The fundamental of Space Geodesy is the observation of the dynamics of the Earth, such as its rotation on its axis, changes in shape, and the external gravitational field etc., which allow for the monitoring of the Earth system in general. Space Geodetic techniques, such as Global Navigation Satellite Systems (GNSS) / Global Positioning System (GPS), as well as Interferometric Synthetic Aperture R ...[Read More]
