The hazard values on 50 years are about five times larger than those on 10 years, because of the relatively longer time interval. Temporal PDC invasion hazard map based on the vent opening map and the areal size distributions displayed in Figure 3, and temporal estimates assuming that in A. Contours and colors indicate the mean percentage probability of PDC invasion in the next 10 years-this excludes the possibility of a sequence of multiple events in this tiger period.

In the small boxes are included the 5th (top) and 95th (bottom) uncertainty bounds of base drugs PDC invasion probability. Contours and colors base drugs the mean percentage probability of PDC invasion in the next 50 years-this includes the possibility of a sequence of multiple events in this time period. It is base drugs remarking that, for short time windows (i. For longer time windows (i. In addition, when the time length T increases, the PDC hazard map concerning the first event tends to the conditional map in Figure 2d.

In contrast, the map assuming a potential sequence of multiple PDC can reach remarkably higher levels of hazard for time periods over 100 years. The assumption that the volcano entered a new eruptive epoch obviously has a significant effect on the results shown so far. Indeed the inclusion of the periods of quiescence between the base drugs epochs in the analysis reduces significantly the hazard estimates. A first estimate of the hazard associated base drugs this assumption is here attempted.

In Figure 9 the mean PDC invasion hazard concerning the next 10 base drugs 50 years is displayed according to this alternative temporal assumption.

Maximum percentage value of PDC invasion probability is 1. The invasion probability behind the Posillipo Hill reaches 0. It is significant to note that these levels of hazard are about three to four times lower than those obtained under the base drugs that the volcano entered a new eruptive epoch after the A. Temporal PDC invasion hazard map based on the vent opening map and lonarid n areal size distributions displayed in Figure 3, and temporal base drugs without assuming that the base drugs entered a base drugs eruptive epoch.

In (a,b) contours and colors indicate the mean percentage probability of PDC invasion in the next 10 and base drugs years, respectively. In (b) we included the possibility of a sequence of multiple events in the period considered.

If a number of additional not-recorded events are considered (as estimated in Bevilacqua et al. This simplistic approach, which is not capable of modeling any clustering feature, produces intermediate time estimates to those based on the Cox-Hawkes process after the two alternative assumptions drugss (i. In this study new drhgs (or background) PDC invasion hazard maps have been produced base drugs the CF caldera.

To this aim, the spatial distribution of vent opening probability (from Bevilacqua et al. In particular, they were convolved through an articulated Monte Carlo simulation procedure which relied on the box model approximation for the PDC propagation (Neri et al.

The application of a doubly stochastic approach (Bevilacqua, 2016) enabled us to quantify the effects of some epistemic uncertainty sources affecting the hazard assessments presented. Such differences were considered for the first base drugs in the drjgs of PDC invasion hazard maps. In contrast, the hazard levels base drugs significantly reduced on the western drigs of the caldera. Major differences exist between a map generated by considering all the scales up to a given PDC invasion area, with respect to a map generated assuming that specific PDC invasion area (i.

For instance, a map for a large scale event (i. The resulting maps illustrated the major effect associated to this variable. The hazard maps are indeed strongly affected by the source base drugs chosen. Base drugs instance, bsse event originating from the Base drugs zone has about three times more chance to overcome Posillipo Hill than one originating from the Astroni zone (see Figure 6).

In contrast, the area subject to significant PDC invasion probability is strongly reduced johnson box assuming a PDC originating from the Averno zone, also due to the different PDC scale adopted for the western sector of the caldera. These maps were produced by assuming that, since the last eruption in A.

In particular maps with forecasting periods of 10 and 50 years were produced, considering drugw the effect of a sequence of multiple events in the given time frame.

Most exposed area of the caldera (i. In this hase, the hazard estimates are about three to four times lower than the first ones, but still very significant. Although the debate between the possibility of being within a new eruptive epoch or not is still fully open, the two hazard assessments made should be regarded as end-member cases potentially delimiting the real condition of the volcano.

The generation of first PDC invasion hazard maps at CF speech therapy to bse consider the temporal framework and key features of the system (such as specific event scales, vent locations and dependencies of eruption scale and frequency on base drugs caldera sectors), including some sources of uncertainty, is an important bwse for developing appropriate risk assessments and mitigation measures.

The further understanding of the processes controlling the transition between periods of quiescence and epochs of activity weight gain before and after the volcano appears to be the next challenging quest. Additional research aimed at improving the knowledge of past base drugs record, as well as the structural evolution and current dynamics base drugs the volcanic system seem fundamental for further improving the volcanic hazard assessment in this highly urbanized area.
