Pairing the Volcano

Isogeny volcanoes are graphs whose vertices are elliptic curves and whose edges are `-isogenies. Algorithms allowing to travel on these graphs were developed by Kohel in his thesis (1996) and later on, by Fouquet and Morain (2001). However, up to now, no method was known, to predict, before taking a step on the volcano, the direction of this step. Hence, in Kohel's and Fouquet-Morain algorithms...

Volcano-earthquake interaction at Mauna Loa volcano, Hawaii

[1] The activity at Mauna Loa volcano, Hawaii, is characterized by eruptive fissures that propagate into the Southwest Rift Zone (SWRZ) or into the Northeast Rift Zone (NERZ) and by large earthquakes at the basal decollement fault. In this paper we examine the historic eruption and earthquake catalogues, and we test the hypothesis that the events are interconnected in time and space. Earthquake...

Predictability of Volcano Eruption: lessons from a basaltic effusive volcano

Volcano eruption forecast remains a challenging and controversial problem despite the fact that data from volcano monitoring significantly increased in quantity and quality during the last decades. This study uses pattern recognition techniques to quantify the predictability of the 15 Piton de la Fournaise (PdlF) eruptions in the 1988-2001 period using increase of the daily seismicity rate as a...

To the centre of the volcano

Introduction transport between the cell nucleus and cytoplasm has captured the imagination of researchers ever since the discovery of the cell nucleus by robert Brown in the early 1830s (Brown, 1866). in eukaryotes, trans­ cription and translation are spatially separated by the double mem­ branes of the nuclear envelope. this alone necessitates a large amount of nuclear transport—that is, the e...
