For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934. Sources: NOAA National Centers for Environmental Information (NCEI), Global Significant Volcanic Eruptions Database. doi:10.7289/V5TD9V7K | Global Volcanism Project / ...
Arenal Volcano has exhibited an almost continuous effusion of lava since September 19th, 1968. Present intra-crater activity is characterized by a relatively quiet rate of effusion accompanied by rhythmic pulsing of the lava due to degassing phenomena. At the vent, the main lava type is aa, ...

Gabbroic enclaves ejected during the current eruption phase (A-1) and during the latest prehistoric eruption phase (A-2) of Arenal Volcano show systematic variations in texture, mineralogy and composition as a function of host rock chemistry and timing of eruption. The most differentiated enclaves ...
Arenal volcanoThe bulk composition of magma erupted from Volcán Arenal has remained nearly constant (SiO 2 = 53.6–54.9wt%; MgO = 5.0–4.5wt%) during almost 30years of continuous activity (1969–1996). None the less, clinopyroxene (cpx) phenocrysts and their spinel inclusions record a much...
