Journal ArticleDOI
Weak mixing in Lake Kivu: New insights indicate increasing risk of uncontrolled gas eruption
TL;DR: In this article, the authors showed that the vertical turbulent exchange is negligible, as documented by a spectacular set of several hundred double-diffusive layers in the East African Rift Lake Kivu.
Journal ArticleDOI
Radon anomaly in the soil of Taal volcano, the Philippines: A likely precursor of the M 7.1 Mindoro earthquake (1994)
Patrick Richon,Jean-Christophe Sabroux,Michel Halbwachs,Jean Vandemeulebrouck,N. Poussielgue,J. Tabbagh,Raymundo S. Punongbayan +6 more
TL;DR: In this article, an anomalous increase in soil-gas radon (peak to background ratio = 6) was recorded, unique in the whole time series, and strong evidence that the Taal radon anomaly originated in stress accumulation preceding the Mindoro earthquake.
Journal ArticleDOI
Degassing the “Killer Lakes” Nyos and Monoun, Cameroon
Michel Halbwachs,Jean-Christophe Sabroux,Jacques Grangeon,Gaston Kayser,Jean-Claude Tochon-Danguy,Alain Felix,Jean-Christophe B´eard,Adelin Villevieille,Gérard Vitter,Patrick Richon,Alfred Wüest,Joseph Hell +11 more
TL;DR: The origin of the Monoun gas burst originates in the release of huge amounts of CO 2 and CO 2 in the lake Nyos and Monoun as discussed by the authors, a region known by geologists for its numerous soda water springs, a common feature of old volcanic areas.
Journal ArticleDOI
Response of Lake Kivu stratification to lava inflow and climate warming
TL;DR: In this article, the authors performed an ad hoc lake survey of the stability of the water column stratification and double-diffusive mixing phenomena in Lake Kivu after the Nyiragongo volcano eruption.
The volcanic risk - How hazardous is the gas accumulation in Lake Kivu? Arguments for a risk assesment in light of the Nyiragongo Volcano eruption of 2002
TL;DR: In this paper, the authors provide an overview on the current knowledge of the stability of the stratification of Lake Kivu and its influence on the safety of the lake and discuss risk assessment arguments based on present day conditions.
