Piton de l. a. Fournaise and Karthala are either safeguard volcanoes within the southwest Indian Ocean. This booklet summarizes the paintings performed on those very energetic basaltic volcanoes. Piton de los angeles Fournaise has an extended background of medical study and tracking, with many facts accumulated in the course of contemporary eruptions. it's considered one of the main studied volcanoes on the earth. The paintings provided during this monograph comprises geological, geophysical, geochemical and petrological elements, but additionally experiences on actual geography, common risks and the sociological and behavioural approaches.'
The Karthala volcano could be much less popular, however it serves as an enticing comparability to Piton de los angeles Fournaise. even supposing located as regards to the volcanoes of Hawaii, it differs from them by way of its extra alkaline magmas and no more common job. It was once additionally monitored for greater than 25 years, generating notable eruptions lately.

This booklet summarizes the reviews conducted at of the main lively volcanoes of Chiapas (Mexico): El Chichón and Tacaná. El Chichón erupted explosively in 1982 killing greater than 2000 humans being the worst volcanic catastrophe in Mexico, and Tacaná produced light phreatic explosions in 1950 and 1986.

2008) and named Sonne Seamount. The ridges and their sedimentary environment have been studied by Fretzdorff et al. (1998), de Voogd et al. (2009), Deplus et al. (2009). The ridges and seamounts protrude from a flat seafloor covered by a few hundred meters of sediments. The morphology of their flanks, their sediment cover and the coating of the dredged samples by Mn-oxides (Fretzdorff et al. 1998) indicate that they are old seamounts. The seismic data show that the sedimentary sequence is deformed and disrupted in several places (de Voogd et al.
Their main argument was that such intrusive complexes usually develop during the ediﬁcation of shield volcanoes, as is the case, for example, for Piton des Neiges volcano (see above) and the Hawaiian volcanoes (Kauahikaua et al. 2000; Ryan 1987). The presence of negative magnetic anomalies (Fig. 78 Ma) are present at fairly shallow depths beneath the younger formations of Piton de la Fournaise and its submarine flank (Gailler and Lénat 2012). On land, the oldest dated rocks of the Piton de la Fournaise volcano (up to 535 ka; Gillot and Nativel 1989; Kluska 1997) are found at the bottom of deep valleys (Rivière des Remparts, Rivière Langevin, Rivière de L’Est) and in La Plaine des Palmistes.
Around 50 individual event deposits have been recognized by Oehler et al. (2008). About one third are interpreted as secondary landslides, affecting previously emplaced debris avalanches. The location and geometry of some mass wasting units suggest source areas on land, in accordance with the fact that dredged samples at the surface of the deposits often have a clear subaerial origin (Cochonat et al. 1990; Lénat et al. 2009a). Recently, Le Friant et al. (2011) proposed that debris avalanches were more developed offshore of Piton de la Fournaise than offshore of Piton de Neiges, where the flanks are more likely to have resulted from a general spreading of the ediﬁce.
