Health and Volcanoes

We are happy to continue our tradition of April-1 stories that are almost true. Some of the science is correct – although we do NOT recommend sulphur-sniffing! April-1 should be a time of happiness. If you would like to re-read our previous ‘almost true’ stories The Sicilian affair Iceland eruption postponement Lava lake to provide…

CSO

One from the archives As I was growing up, having an interest in things geophysical/astrophysical, there was always a search for the “wow” factor. Not everyone’s “wow” sense is geared the same… and in some cases, the scale of stuff that people are familiar with has a lot to say about how they perceive the…

Hiawatha

Snow is beautiful. It turns the world white and unblemished. Children love it for play, grown-ups love it for what it hides. Soon the snow will melt again, or worse, it will age like the world ages, lose its colour and become pockmarked with dirt. The beauty is temporary, here today, gone tomorrow. What was…

Sounds and shakes

For the walls are woven Of Serpents spines.” Völuspá, Níðhöggr First Stanza.   I come from the North, and in our traditions and old religious motifs, we have always known…

Hunga Tonga and The Supercriticality Event

As the numbers for the Hunga Tonga eruption continues to come in it is becoming ever clearer that something truly momentous happened, something not seen or heard in 139 years. With a columnar height of 55 kilometres, an explosive pressure wave travelling several laps around the planet, forming a medium sized deadly tsunami, gouging out…
