Mississippi Blues: The earthquakes of New Madrid

The Mississippi valley had once been densely inhabited, but it was so no longer. The Indian cultures had been decimated by disease; their lands were emptied and their villages deserted. The area had just become US property, and American settlers were moving in but it was still early days, here on the western frontier, in…

Up!

When the ground starts to rise beneath your feet, it is time to sit up. Fishermen would be the first to notice, being unable to leave their harbours due to lack of sea. Governments would discuss the risk of reduction in tax income from fishing, and would commission research. The scientists report evidence of widespread…

The Canadian wilderness eruption: Tseax volcano

It rains a lot in British Columbia. Here is where the Pacific Ocean dumps its excess moisture. The mountains are covered with trees; the lichen-covered branches drip in the seemingly perpetual rain or drizzle. The summers are mild and dry but don’t last long enough. The everlasting days soon end, and the autumn rains and…

In other places, deep scratches in the stony surface, all pointing in one direction. U-shaped valleys are found in hills, a shape which rivers don’t do. To the readers of the landscape, it…

(From Rachel Carson: Silent Spring) The history of life on earth…

Life’s end: mass extinctions

The Bogoslof eruption

Volcanoes are the tip of an iceberg. 90% of the volcano is hidden, down to the magma chamber 10 km or more below the surface. What we see is only the cone on top of the conduit. The perfect cone of Fuji, or even St Helens (before it blew up), is like the hat on…

Volcano’s child

Child The volcano towers; forms a mountain sublime Build by eruptions and matured over time But a new site is feeding from its magma supply A small mountain is trying to reach for the sky The volcano watches a new cone unfold Child of its magma. New life to behold The little volcano plays with…
