Researchers have tried for decades to determine whether there is a reliable precursor that can act as an early warning before the shaking begins. The technology to predict when an earthquake will str...
Read MoreScientists are planning a “CAT scan” of a British Columbia volcano to help harness the underground heat that turns rock into magma for renewable energy. “Canadians are often surprised to know there...
Read MoreWhen it comes to open pit mines, generally, the steeper the slopes, the greater the ore extraction, but at what cost to safety? This is an age-old question for geotechnical engineers working in the m...
Read MoreIt was impossible to foresee what began as heavy rainfall on 18 May, 2020, would end with the brutal failure of both the Edenville and Sanford dams in Michigan, USA. But the catastrophe could have b...

Read MoreWhether in a recently reclaimed land or a densely populated area, excavating on soft and heterogeneous soil can make it challenging to understand the ground response. This highlights the importance o...
Read MoreBy Reginald Hammah and Frema Awuku-Asabere Here are some intriguing “do you know” questions for you: Do you know the value of acceleration due to gravity for the Moon? What about that for Mars? Do y...
Read MoreSlope failure induced by rainfall is a common geotechnical problem in tropical locations with abundant soils; landslides in Hong Kong are one such example. Soils found in tropical locations typically...
Read MoreAn overview of the application of XFEM in jointed rock slopes for discontinuities Introduction: Modeling jointed rock slopes is one of the more challenging problems in rock mechanics. The position an...
Read MoreBy Reginald Hammah and Frema Awuku-Asabere A lot has been written about 3D slope stability analysis generating factors of safety that can be higher than 2D results by up to 20%. But is this true? We...
