Co-benefits of Nature-based Solutions: what we know and what we should know

Co-benefits of Nature-based Solutions: what we know and what we should know

Nature-based Solutions are on everyone’s lips in the view of their risk reduction potential but also their social, economic, and environmental side effects (so-called co-benefits). But how significant are these co-benefits? What are NBS? Nature-based Solutions (or in short NBS) are an umbrella term for ecosystem-based solutions to counteract societal challenges such as climate change, …[Read More]

TS Must-Read – Cannat et al. (2006) Modes of seafloor generation at a melt-poor ultraslow-spreading ridge

For the first time in 2006 Cannat and co-workers described a smooth seafloor type in the mid-ocean ridge located in the SW Indian Ocean (SWIR). The 660-km-long off-axis bathymetry, gravity, and magnetic dataset presented in the study lies near the Rodrigues triple junction (RTJ in Fig. 1). The must read paper expanded the previous conceptual …[Read More]

COVID-19 and natural hazards: a complex multi-risk scenario

COVID-19 and natural hazards: a complex multi-risk scenario

COVID-19 has been a disruptive ‘tsunami’ that most countries were not prepared to handle. The pandemic has been representing a global slow-onset long-lasting disaster that has drastically challenged all emergency management systems worldwide. The pandemic slow-onset disaster has been characterized by a prolonged emergency phase with varying intensity levels, and a cyclic behavior, where the …[Read More]

On the Frontline of the Mission for Marsquakes

On the Frontline of the Mission for Marsquakes

This week we interview Géraldine Zenhäusern, a PhD student at ETH Zurich’s Department of Earth Sciences, about her experience of being on the frontline of spotting Marsquakes with NASA’s InSight mission…. What is the InSight mission? The NASA InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission is a geophysical observatory (see Fig. …[Read More]

Outcrop analogues to Carbon Sequestration Targets: the Gog Quartzite of Alberta – including a short virtual field trip!

Outcrop analogues to Carbon Sequestration Targets: the Gog Quartzite of Alberta – including a short virtual field trip!

Introduction In 2022 I was asked to put together a virtual field trip looking at carbon sequestration (CCS). We are particularly lucky in Alberta in having three excellent Cambrian targets for CCS including the Basal Cambrian Sandstone, currently being used for CCS in Shell’s QUEST project, quartzites of the Deadwood Formation (being utilized for a …[Read More]

Arc and Intraplate Volcanism in Northeast Asia Since mid-Miocene: Numerical model studies

Arc and Intraplate Volcanism in Northeast Asia Since mid-Miocene: Numerical model studies

Northeast Asia may be one of the best natural laboratories to investigate both arc and intraplate volcanisms which have developed since the mid-Miocene. The arc volcanoes have occurred above the sinking young (Philippine) and old (Pacific) oceanic plates in Southwest and Northeast Japan subduction zones, respectively. The intraplate volcanoes across the Korean Peninsula and China …[Read More]
