Physico-chemical and isotopic composition of some lakes and springs in the Bamenda Highlands, North West Cameroon

19 Sep 2013 | Workshops | Contributor(s): Mengnjo Jude Wirmvem

The Bamenda Highlands (6o12’N, 10 o24’E), Northwest Cameroon, is located mid-way along a chain of volcanoes (ca. 1600 km long) cutting diagonally across Cameroon called the Cameroon Volcanic Line (CVL). The area is characterized by volcanic lakes and springs. Information on the chemical...

Plates vs. Plumes Debate

07 Oct 2011 | *Data Sets/Collections | Contributor(s): Gillian Rose Foulger

Early in the 21st century, scientists became increasingly skeptical about the deep-mantle plume hypothesis. This postulates that unusual volcanism results from thermal diapirs ("plumes") that originate at the core-mantle boundary and deliver hot material via narrow conduits to Earth's surface....

Plots of Wind Patterns of the World's Volcanoes

This product includes rose diagrams and tables of wind patterns at volcanoes listed in the Smithsonian Institution’s Volcanoes of the World Database.  At each volcano, the speed and direction of wind above the volcano were read from output of the NCEP/NCAR Reanalysis 1 model, at...

PlumeMoM

27 Mar 2015 | Offline Tools | Contributor(s): Mattia de\' Michieli Vitturi

PlumeMoM is a numerical code for the steady-state plume model, describing the rise in the atmosphere of a mixture of gas and volcanic ash during an eruption. The system of equation is formally the same of that presented in Barsotti et al. 2008, i.e. the equations we formulate describe the same...

Plumeria 2.3.1

06 Dec 2011 | Offline Tools | Contributor(s): Larry Garver Mastin

This is a graphical 1-D steady-state model for the dynamics of volcanic plumes. Written in Visual Basic, it runs on all computers having a Windows operating system (Windows 98 or later).Input values are entered into text boxes in the GUI. These magma temperature, gas content, vent diameter,...

Plumeria_wd--Fortran open-source version

06 Dec 2011 | Offline Tools | Contributor(s): Larry Garver Mastin

This is an open-source Fortran version of Plumeria, a one-dimensional steady-state model for volcanic plumes. It calculates plume properties such as upward velocity, radius, density, mass fractions of particles, air, water vapor, liquid water and ice, as a function of height in a plume.  The...
