NPG Paper of the Month: “Inferring the instability of a dynamical system from the skill of data assimilation exercises”

The NPG paper of the month was awarded to “Inferring the instability of a dynamical system from the skill of data assimilation exercises” by Yumeng Chen, Alberto Carrassi, and Valerio Lucarini. Geophysical systems are usually described by a set of dynamical equations that are often non-linear and chaotic (Ghil and Lucarini, 2020). Errors about the initial state can grow, shrink, or sta ...[Read More]

TS Must Read – Scholz (1998): Earthquakes and friction laws

Scholz (1998) is the “must-read” review article about rate- and state- variable laws of rock friction. The article is a robust introduction to the state-of-the art of the discipline at the end of the past century and should be considered of particular interest for students and/or early career scientists. In spite of its relative simplicity, rock mechanics unfortunately is still not taught universa ...[Read More]

Breaking the glass ceiling in diversity, equity, and inclusion in geosciences

Despite many efforts around Diversity, Equity, and Inclusion (DEI) in Science,Technology, Engineering, and Mathematics (STEM), a noticeable disparity in geosciences still exists. To understand the root cause and steps we can take forward, it was my privilege to talk with Dr Kuheli Dutt, Assistant Dean for DEI at the Massachusetts Institute of Technology (MIT). Before MIT, Dr Dutt was an Assistant ...[Read More]

GeoPolicy: Climate solutions at the center of focus this Earth Day

Earlier this month, Climate Change 2022: Mitigation of Climate Change was published by the IPCC Working Group III as the third instalment of the IPCC’s Sixth Assessment Report (AR6). It emphasises that “rapid and deep” greenhouse gas emission reductions are needed across all sectors to have any chance of keeping the world below 1.5°C of warming above pre-industrial levels. However, it also outline ...[Read More]

Celebrate Earth Day with the Deep Earth Explorers!

Happy Earth Day 2022! To celebrate this event in a slightly different way, EGU Seismology blog editor Matthew Kemp thought he’d go on a journey to the centre of the Earth, and highlight the work of the Deep Earth Explorers… Back in March 2020, Professor Sanne Cottaar‘s Deep Earth seismology group at the University of Cambridge, UK, unveiled their new exhibit “Deep Earth Exp ...[Read More]

Hydrologists celebrate Earth Day 2022

Today is Earth Day. As hydrologists, we work closely with what covers about 71% of the Earth’s surface: water! How do you feel when surrounded by Earth’s nature? How would you describe the contribution of your research on the water cycle to the wellbeing of our planet? If you should prepare a warning sign to join people marching in the streets on this special day, what would you write? ...[Read More]

More pancakes in the future!

More pancakes in the future – that sounds like a very good New Year’s Eve resolution for Sunday brunches, but it could also be a development of the most tasty looking sea ice shape in the Arctic. Let’s find out more! Arctic Sea Ice The growth and melt of Arctic sea ice follows a seasonal cycle. In the springtime, under the midnight sun, the sea ice begins to melt until it reaches its m ...[Read More]

How to EGU22: Five ways you can help us make a greener EGU22!

For several years, EGU has committed – both in terms of resources and research – to helping to create a cleaner and greener environment. As our biggest event of the year (EGU22) soon approaches, nearly 10,000 people are expected to travel to Vienna for the week-long conference. An event of this scale can of course impact the environment any number of ways. The good news? Even the small ...[Read More]

Volcanoes and social media make us (more?) crazy

Many people are drawn to danger and behaviors that can harm their health or finances. Dangerous activities include the attraction that humans have always had towards natural events, such as volcanic eruptions, or towards gambling, adventure, challenging travels or physical activities without the ability or the necessary preparation. In today’s life many people face risks, however these risks ...[Read More]
