How Ancient Egyptian Decline Synced With Hydrological Change….And How They Survived

How Ancient Egyptian Decline Synced With Hydrological Change….And How They Survived

Cairo’s survival was, is, and will be dependent on the flow of the Nile. Since the city was founded in 10th century CE the Nile’s scouring waters have left behind untouched ground onto which the city has spilled and grown. Modern Cairo’s youngest districts are closest to the Nile, founded on earth which was underwater centuries before. It is the river’s changing nature that made the Nile Val ...[Read More]

What are Snow Mechanics and why should we care?

What are Snow Mechanics and why should we care?

Every time we walk, ski, drive or build upon snow, we’re relying upon the theory of Snow Mechanics; but what is that and why should we care?  Mechanics is the engineering terminology used to describe “the branch of applied mathematics dealing with motion and forces producing motion” (Oxford Languages) or more simply, the study of motion, in our case the motion of snow. What causes snow to move? Ge ...[Read More]

Living with a Volcano

and June 8, 2022
Living with a Volcano

Since ancient times, the growth of populations has been strongly combined with the presence of volcanoes, due to their ability to provide nutrients to soils (and so to agriculture) and resource extraction. One great example is described in our blog post about Volcanoes and wine. However, living near a volcano has its (obvious) drawbacks, starting with lava flows (see the recent Cumbre Vieja erupti ...[Read More]

Geomythology. The Sicilian Trilogy – Part II: Vulcano, Vulcan’s forge

Why is a fork actually called fork? And why are volcanoes actually called volcanoes? While I do not have any reply for the first question, I have one for the second… and with a quite interesting story. The Earth currently has around 1350 potentially active volcanoes, aside from the volcanoes along the spreading centres (USGS faq); all of them are named after a single volcano, called Vulcano. Vulca ...[Read More]

Did you know… that glaciers can sing?

Have you ever wondered what the voice of a glacier sounds like? Well, listen here! And if you want to know how the glacier makes these sounds, then let’s take a walk on the ice side… Close your eyes and think of the time you were in the middle of the mountains. On a snow plain, a glacier or a frozen lake; just you. You hear your footsteps in the snow, crunching ice. The wind blows through your hoo ...[Read More]

Visualizing the invisible through art

Visualizing the invisible through art

authored by Grant Ferguson Groundwater is often thought of as out of sight out of mind and has even been accused of being not photogenic. The typical visualization tools used by hydrogeologists include maps, cross-sections and graphs. These can be effective, especially amongst ourselves, but it is difficult to invoke the sort of emotional response that is typical from seeing other hydrologic featu ...[Read More]
