Meet the blog illustrators: Vojta Hýbl
Vojta Hýbl from the blog illustration team (photo taken by India Hunkin). Spreading research news to a broad audience is important but difficult work for scientists. Luckily, we have an amazing illustration team who are happy to share their artistic creation. Their artwork has helped us expand the readership and made our blogs increasingly popular. …[Read More]
Democratising Climate Information
How can we ensure a greener and more equitable future for everyone in the forthcoming years? In this week’s blog, Professor Monica Sanders from Georgetown University and Tulane University shares her thoughts on how and why we need to democratise climate information towards the general public and primarily to the divested communities that are being …[Read More]
The Geodynamics Division @ EGU23
With the EGU General Assembly (GA) less than a month away, it’s time for attendees to start planning their schedule to get the most out of the week. In today’s blog, Geodynamics (GD) Division Early Career Scientist (ECS) representative Megan Holdt highlights the networking events for the GD Division, provides an overview of key events …[Read More]
How does slab tearing evolve?
Slab tearing refers to the gradual propagation of the break-off of a subducting plate. As observed in numerous modern and ancient convergent tectonic settings, the growth of the tear “window” in the downgoing plate has strongly influenced various geologic and geodynamic processes, such as depocenter migration of foreland basins, uplift rates in mountain ranges, earthquakes, …[Read More]
The first observational evidence for a volcanically active Venus
Our neighbouring planet Venus is gaining popularity in the terrestrial planetary sciences, especially since the selection of three new Venus missions by NASA and ESA in 2021. Now, for the first time ever, scientists have directly observed surface changes that indicate active volcanism on Venus. This discovery was made with data from NASA’s 30-year-old Magellan …[Read More]
Geodynamics 101 – Viscous anisotropy
We are living in an anisotropic world. From rock-building crystals, ice, and trees growing in your garden to your favourite slice of cake many materials or objects has some anisotropic behaviour. What does this mean? Anisotropy (non-isotropy) implies that a material property depends on the direction of the measurement. In geodynamics we often talk about …[Read More]
Study of the Lithospheric deformations, Earthquakes, Tsunamis, Volcanic eruptions and their imprints in Atmosphere using Space Geodetic Observations
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 …[Read More]
Ambient seismic wavefield: how noise can be a signal
Every now and then, the surface of our planet shakes violently during earthquakes like the recent magnitudes 7.8 and 7.5 Kahramanmaraş Earthquake Sequence in Türkiye. These vibrations are recorded by instruments called seismometers and are then processed and analyzed by seismologists to study the earthquake processes themselves as well as other deep Earth structures. Interestingly, …[Read More]
