Earthquake Watch January: Guyana Mw 5.6

EGU Seismology ECS Team February 25, 2021

South America is one of the most seismic regions where the collision of several tectonic plates is shaping the topography along the Pacific coast. On January 31, an Mw5.6 earthquake hit Southern Guyana near the border with Brazil. This event was largely felt in Boa Vista (Brazil), the nearest main city close to the epicentre …[Read More]

Open teaching to navigate hydrology: how ready are we?

Bettina Schaefli February 24, 2021

Around a year ago, I all of a sudden had to find a quick solution to do online teaching. The timing was perfect: start of the semester, start of online teaching, video conference infrastructure unavailable, three kids at home and me, a hydrology teacher who has never produced any kind of video exceeding a 20s …[Read More]

The Indian Ocean Geoid Low at a plume-slab overpass

Elodie Kendall and edited by Anne Glerum February 24, 2021

In this week’s News & Views, Postdoc Elodie Kendall from GFZ Potsdam shares with us recent work on the mantle structures that could explain the Indian Ocean Geoid Low. What is the geoid, what does it look like and what can it tell us about mantle structure? The geoid is …[Read More]

2020: The escalation of extreme rainfall events in Brazil

Paulo Hader February 22, 2021

In summer 2020, extreme rainfall events dumped up to 320 mm of rain in a single day in the Baixada Santista metropolitan region, São Paulo state, breaking Brazil’s record for the biggest rainfall in a single event and demonstrating one of the greatest threats of climate change. The damage caused by the associated landslides led …[Read More]

Subglacial Hydrology For Dummies – Water, water everywhere…

Samuel Cook February 19, 2021

Glaciers are mostly made of water. Sometimes, perhaps more than we’d like, some of that water makes a break for it by melting, the inconstant molecule… It might pootle around on the surface of the glacier a bit and get a lot of remote sensers very excited, but it’s what it does once it gets …[Read More]

The Sassy Scientist – #WriteProperly #NoMoreAcronyms

The Sassy Scientist February 19, 2021

Nerea cannot get enough of writing papers, reports and proposals. However, actually reading scribbles, especially those jotted down by (under)grad students, leaves her a histrionic gasp. She thus ejaculates: LLSVP or LLVP or LL(S)VP – why must we prolong the acronym wars? Aupa Nerea, The Americans. No doubt. It has got to be them. Just …[Read More]

Four reasons for still observing cold spells despite the undeniable global climate change

Davide Faranda February 18, 2021

The winter of 2020-2021 has been characterized by various cold waves affecting – at different times – Western and Eastern Europe and North America. The most striking pictures show Madrid covered by up to 40 cm of fresh snow, frozen Thames near London and Canal St Martin in Paris, heavy snow in Amsterdam and even …[Read More]

Rayleigh-Taylor instability in geodynamics

Dip Ghosh and edited by Jyotirmoy Paul February 17, 2021

Flow against gravity is a common feature in the geodynamic phenomenon. In this week’s Geodynamics 101, Dip Ghosh from Jadavpur University Geodynamics Lab will explain the fundamentals of Rayleigh-Taylor instability: A key to understanding the anti-gravity flow. It has long been realized that most of the geodynamic processes can be described in terms of slow …[Read More]
