**************************************************************************************************** Piton de la Fournaise volcano eruption. From: Guillaume LEVIEUX <levieux@xxxxxxxxxxxxxxx> **************************************************************************************************** Piton de la Fournaise volcano erupted Monday, December 14, 2009 at 18:45 (local time GMT +4). The eruption was preceded by a seismic crisis and a raise of the summit area deformations, which started at 17:30 (GMT +4). The eruptive tremor began at 18:30 (GMT+4). A system of sub-parallel fractures along the summit of Dolomieu crater fed lava flows on the southern slope of the Piton de la Fournaise, inside the Enclos Fouqué. A second fissures system opened on the eastern flank of the Dolomieu summit crater at 20:25 (GMT +4). Then lava flows were spent towards the eastern slope. This eruption ended during the night at 00h40 (GMT +4) after a gradual decrease in magma supply from midnight (local time). This morning, Tuesday, December 15, 2009, a visible degassing in the south and southeast fractures is associated with a low intensity eruptive tremor. All of the lava flows was confined to high zone of the volcano and more specifically the slopes south and south-east of Piton de la Fournaise.
