It's been a busy few days at #EGU26 in Vienna - catching up with friends and meeting new people, lots of interesting science and discussions, especially in our session on Seismic imaging with uncertainties. To top it all off, a nice session dinner and a view over the Donau Insel on my way home!

This is a huge mistake. My experience on NERC panels is that resubmissions score higher and are more likely to be funded: the review process improves good proposals that should not be lost (along with the time spent on them).

For an earthquake prediction to be meaningful, it has to specify a time, location, and magnitude range that is unlikely to occur randomly. So who can predict earthquakes? - NO ONE. This video breaks it down. youtu.be/F4Ypv0PmDDE

"It might never happen..." Remembering forgotten earthquakes in Central Asia
Where in the world do earthquakes pose the greatest risk? Japan, perhaps...or California? When devastating earthquakes hit the news headlines, they implant themselves in our memory, and we create a long-lasting association between the location and the event. But what about the earthquakes that lie outside of living memory? Are the locations of these events perceived to hold the same degree of risk? In this film, Professor Richard Walker and Dr Neill Marshall from Oxford's Department of Earth Sciences share their work on the forgotten earthquakes of Central Asia, and explain the societal implications of natural disasters that have faded into the past.

So NERC have quietly announced this afternoon that they're delaying/cancelling/suspending, whatever 'not launched at this time' means, their 2025 Independent Research Fellowship round. After announcing it 34 days ago. Flip-flopping like this is really detrimental to early career researchers.
