Sea-level change is thought to influence the frequencies of volcanic eruptions on glacial interglacial timescales. However, underlying physical processes and their importance relative other influences (for example, magma recharge rates) remain poorly understood. Here we compare an approximately 360-kyr-long record effusive explosive from flooded caldera volcano at Santorini (Greece) with a high...

The dichotomy between explosive volcanic eruptions, which produce pyroclasts, and effusive lava, is defined by the presence or absence of fragmentation during magma ascent. For lava fountains distinction unclear, since liquid phase in rising may remain continuous to vent, fragment fountain, then re-weld on deposition feed rheomorphic flows. Here we use a numerical model constrain controls basal...

No similar measures exist for the sizes of volcanic eruptions, making i...

Explosive volcanic eruptions are responsible for producing localized pyroclatic deposits found across the lunar surface. These small pyroclastic thought to have erupted through transient, vulcanian-like eruptions. We used several remote data products, including a water abundance map, understand compositional and physical properties of these deposits. Within deposits, we strong relationships bet...

The oldest-known rocks of the eroded Dunedin Volcano (DV), New Zealand, active 16.0–11.0 Ma, were emplaced by penecontemporaneous explosive eruptions and intrusions magmas with a remarkable range compositions, including basanite, alkali basalt, trachyte phonolite. compositional diversity in rapid succession during earliest development volcano signify existence complex magmatic system highly evo...

Shinmoe-dake volcano, which is within the Kirishima volcanic complex, Japan, erupted from March to June 2018. The eruptions were recorded by various geophysical instruments that installed 3.1–5.4 km crater. Here we present first documented evidence of infrasound-induced electric-field changes in near surface at time explosive eruptions. Significant coincide with infrasound arrivals. An order-of...

Grain-size distributions and thicknesses of tephra layers are used to reconstruct characteristics, dynamics, hazards explosive volcanic eruptions, but the extent which preservation is influenced by depositional environments unclear. This paper analyses grain-size produced Eyjafjallajökull (2010) Grímsvötn (2011) eruptions. We collected 110 samples layer thickness measurements from 86 sites at t...

The tropical response to explosive volcanism remains underconstrained in the paleoclimate record. While atmosphere cools due aerosol forcing following volcanic eruptions, modeling evidence suggests that Pacific responds with compensatory warming. Given rarity of large eruptions and short instrumental record, these results require independent verification. Here, we test for links between dynamic...
