“…This alternative interpretation suggests a common secular process involving the complete South American Pacific margin in a slowly expanding Earth framework. (Scalera, 2008). The results of the Lima paper (Scalera, 2008) were purely phenomenological and did not indicate a causal link.…”

“…(Scalera, 2008). The results of the Lima paper (Scalera, 2008) were purely phenomenological and did not indicate a causal link. Nevertheless, they did present the possibility (not the certainty) of a repetition of the correlation-events with an imperfect periodicity of about 45 yr.…”

“…Although not explicit in the preceding work (Scalera, 2008), it is clear that the subdivision of the time-axis on a calendar year basis (using a minimum resolving power of 1 yr) is an artefact -dictated by a frequent lack of days and months for the catalogued onset and conclusion of eruptions -inapplicable in nature. This subdivision of time into a series of equal adjacent intervals lasting 1 yr is necessary for the treatment of the data for drafting Fig.…”

“…However, when reanalysing the data the following set of five criteria were adopted: (Siebert et al, 2011). Light blue bands mark the new entries in the volcanoes list compared to the data used in analysis a few years ago (Scalera, 2008). On the time axis 1800-2010 the eruptions are represented by rectangular bars, horizontal length of which is equal to the duration of the eruption and following the Volcanic Explosivity Index (VEI) colour scale on the right.…”

“…Due to its potential implications, an alternative conception worth scrutinizing is the non-compressional explanation for mountain building (Ollier, 2003;Scalera, 2007aScalera, , 2008. The main advantage of the non-compressional schema is the possibility of explaining major shallow earthquakes not as the subhorizontal slippage of a subducting lithosphere but as sudden vertical movements along the complementary perpendicular fault plane of the focal mechanism (Scalera, 2007c), under the forearc.…”

Abstract. During his trip on the Beagle, Charles Darwin wrote about the eruptions associated with the Concepción earthquake of 1835. A later survey by Lorenzo Casertano, following the great 1960 Chilean earthquake, identified some unclear evidence of a link between eruptions and the seismic event, although some reservations were also raised. Using data available in 2006 in the Smithsonian Institution Catalogue of volcanic eruptions, Scalera revealed grounded evidence that South-American Wadati-Benioff zone earthquakes of magnitudes greater than 8.4 are associated with an increased rate of volcanic eruptions, but it was still impossible to determine a causal link between the two phenomena. An average return period of about 50 yr was deducible from the data for the time window 1800–1999. After 2006, the Smithsonian Institution's effort to improve our knowledge of this region has greatly increased the completeness of the catalogue, adding the eruptions from the 2000–2010 interval, together with 50 % more new entries in the list of Andean volcanoes. The great Chilean Maule earthquake of 27 February 2010 (M=8.8), occurring exactly five decades after the 1960 event, provided an occasion to reanalyse this updated database. The results suggest a preferential causal eruptions-earthquake relationship, but additional future volcano-seismic events should be studied to arrive at a definitive conclusion, within the perspective of using this phenomenon for Civil Protection. The possible correlation of South American volcano-seismic events with the Markowitz oscillation of the Polar Motion is another good reason for trying to establish an integrated geodynamic explanation.

given scale for graphical reasons. The diurnal and semidiurnal rates of stress changes are of course always (without any exception) larger than the fortnightly variations as can be seen in Fig. 3 where all the curves are depicted including a scale.The corrected sentence should thus read as follows:As the diurnal and semidiurnal rates of stress changes are larger than the fortnightly variations, their effect on degassing should accordingly be more pronounced, which is consistent with the high variability of the SO 2 fluxes throughout a day. The original article has been published with a misleading error on page 11 (bottom left), second sentence of subsection The fortnightly cycle. The respective sentence reads:As the diurnal and semidiurnal rates of stress changes are larger than the fortnightly variations, except for the period around the fortnightly tidal minimum (Fig. 7b), their effect on degassing should accordingly be more pronounced, which is consistent with the high variability of the SO 2 fluxes throughout a day. The fortnightly tidal curve (black line) in Fig. 7b is, however, amplified by a factor ~10 with respect to the The online version of the original article can be found under
