Flare characteristics: Properties of eruptive and non-eruptive events and their associations
Advances in Space Research, 2003Abstract The complex: relationship between solar flares and coronal mass ejections is investigated using a comparison of flare parameters for a total of 69 ejective and non-ejective flares. In the case of solar flares which do not show mass ejection there seems to be a clear relationship between the peak intensity and duration, with higher intensity ...

Eruptive fracture location forecasts from high‐frequency events on Piton de la Fournaise Volcano [PDF]
Geophysical Research Letters, 2013 Piton de la Fournaise (La Réunion island) is a very active basaltic volcano, with five eruptions between Nov 2009 and Dec 2010. Pre-eruptive seismic crises usually last for a few hours and mainly consist of a volcano-tectonic swarm. During the quiescent

Geoefficiency of solar eruptive events
Geomagnetism and Aeronomy, 2009The sources of geomagnetic disturbances during 1999–2003 are discussed. The relation between geomagnetic activity and the rate of coronal mass ejections (CMEs), their parameters, and the dynamics of solar photospheric magnetic fields is considered. It is shown that during the reorganization of unipolar regions of the photospheric magnetic field, the ...

Subplinian eruptions are generally characterized by unsteadiness in magma discharge, which is reflected in the formation of strongly oscillating convective columns. As a result, the pyroclastic fall deposits show clear grain size stratification, and are frequently interlayered with small-volume pyroclastic density currents. The causes of this pulsatory

A seasonal dependence for the geoeffectiveness of eruptive solar events
Solar Physics, 1993The pronounced seasonal variation of the occurrence rate of great geomagnetic storms, attributed to in-ecliptic draping of interplanetary magnetic fields and the Russell-McPherron effect, suggests that the geoeffectiveness of the causative eruptive solar events has a seasonal dependence. Thus an eruptive solar event of a given ‘size’ occurring near the
