The long-term seismic impact of mega thrust earthquakes

Here’s a very interesting analysis of aftershock patterns in the wake of M9+ megathrust events: the aftershocks in a ‘core’ region closest to the rupture shut off within a few years of the main shock, after which seismicity might remain … Continue reading

Weird rocky exoplanets

Obtaining the composition of rocky exoplanets from the spectral signature produced when their dying parent star eats them is already pretty mind-blowing. But the results – which suggest that on some of these worlds, quartz is substituted for olivine in their … Continue reading

Diversity (or lack thereof) in geoscience: are we hyping up the wrong things?

Via Dr Sarah Greene, some data from a survey of student attitudes to STEM careers, including geosciences, at a college in the SW US indicates that they care more about whether their career can help people or the environment than the … Continue reading

Why do we get earthquakes a long way from plate boundaries?

There’s already a lot of good info out there about this week’s magnitude 5.9 earthquake near Melbourne, Australia. I wanted to dig a little more into the broader reasons you can get earthquakes like this in places you might not … Continue reading
