A transnational, valley-blocking landslide in Africa
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. On 23 February 2024, a large valley-blocking landslide was triggered by heavy rainfall in the Ruzizi Valley, to the south of the city of Bukavu, which is in the Democratic Republic of […]
ارتفاع درجة حرارة المحيطات يمهد الطريق لحدوث موجات جفاف خطيرة، ولكن يمكن التنبؤ بها، في شرق أفريقيا
اكتشف العلماء رابطة بين التدرجات الحرارية في المحيط الهادئ وبين موجات الجفاف الفتاكة والتي يمكن التنبؤ بها في شرق أفريقيا.
Using Machine Learning to Reconstruct Cloud-Obscured Dust Plumes
Satellite-observed dust plumes from North Africa are frequently obscured by clouds, but a new study uses machine learning to reconstruct dust patterns, demonstrating a new way to validate dust forecasts.
Planet Labs imagery of the Mount Hanang debris flows in Tanzania
On 21 December 2023, Planet Labs captured imagery of the Mount Hanang debris flows in Tanzania, highlighting that many failures coalesced into channelised debris flows.
Ostrich Eggshells Trace Namaqualand’s Ancient Rain
The plant-based nitrogen eaten by ostriches and stored in their eggshells was measured by researchers 20,000 years later.
Katesh and Gendabi: the 2 – 3 December 2023 channelised debris flows in Tanzania
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. On 2 – 3 December 2023, very heavy rainfall struck the Northern Manyara region in Tanzania in Africa, triggering damaging landslides. Worst affected appears to be the area of Mount Hanang, a […]
Sinking Cities and Rising Waters
Climate-driven sea level rise combines with land subsidence in some of Africa’s fastest-growing cities.
Affordable Robots Measure Soil Respiration
Measuring soil carbon flux, also known as soil respiration, can be expensive or time-consuming. A set of affordable robots that gather these data autonomously could especially benefit the Global South.
Ocean Warming Sets the Stage for Dangerous but Predictable East Africa Droughts
Scientists have uncovered a connection between temperature gradients in the Pacific Ocean and deadly but predictable consecutive dry spells in East Africa.
