However, these are thought to be effusive eruptions producing fluid basalt lava rather than explosive eruptions producing ejecta. The Paraná and Etendeka eruption(s) occurred about 128 to 138 million years ago.

Eruption-fed facies are characterized by the dominance of unmodified juvenile components of uniform composition and thick to very thick, mass-flow sedimentation units. Facies (1) and (2) above are both eruption-fed and related to effusive or explosive eruptions, respectively. In many cases, ...
explosive eruptions are less voluminous than effusive eruptions. Surprisingly, however,explosive volcanismis common (although not abundant) throughout the inner Solar System. Farther away from the Sun, water ice dominates volcanic processes. Cryovolcanism seems to have occurred on Europa, Enceladus, Tita...

The condensation aerosol dominated the mass during the later stages of the eruption when the explosive activity had ceased, and was characterized by the greatest variety of particle compositions. Na㎏ sulfate and Fe (III) oxide comprised more than 95% of the solid fraction of the condensation ...
As part of the dome emplacement episode, the crater lake progressively dried, leaving isolated pools which then promoted persistent mud/sulphur eruption activity starting in mid-January 2013. We interpret the emplacement of the dome as a non-explosive process where the hot...

Indeed, for explosive eruptions power law acceleration in the seismic rate is observed in a temporal interval of few days up to 10 days before eruptions [406,407]. Conversely, before effusive eruptions the final approach to eruption time is much shorter, ranging from tens of minutes to tens ...
After the caldera-forming eruption, magmatic activity resumed at the rims and inside the caldera, forming three volcanic centers. Such activity was mostly effusive whereas the most recent manifestations at Mt. Sibayak were explosive, indicating a possible change in eruptive style with time. We sampl...
