Magmatic lull (Volcanology 🌋)
A magmatic lull is a period of declined magmatic activity in volcanically active regions. They may occur as a result of underthrusting of hinterland lithosphere beneath a volcanic arc, changes in subduction parameters such as relative velocity, direction and slab dip, arc-arc collisions and subduction hinge advance. Individual magmatic lulls may last tens of millions of years between period...
Volcaniclastics (Volcanology 🌋)
Volcaniclastics are geologic materials composed of broken fragments of volcanic rock. These encompass all clastic volcanic materials, regardless of what process fragmented the rock, how it was subsequently transported, what environment it was deposited in, or whether nonvolcanic material is mingled with the volcanic clasts. The United State...

Second earthquake swarm hits Campi Flegrei one day after state of emergency declaration
A new #earthquake swarm began in the Campi Flegrei caldera at 14:23 local time on May 14, 2025, just five hours after Italy’s National Institute of Geophysics and #volcanology (INGV) reported the end of a previous swarm that led to a state of emergency declaration.

Glacial lake outburst flood (Volcanology 🌋)
A glacial lake outburst flood is a type of outburst flood caused by the failure of a dam containing a glacial lake. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup. The dam can consist of glacier ice or a terminal moraine. Failure can happen due to erosion, a...
Bulusan volcano erupts, triggers pyroclastic flow and ashfall in Sorsogon Province, Philippines
A phreatic eruption occurred at Bulusan #volcano, Philippines, on April 28, 2025, generating a 4.5 km (1 650 feet) high ash plume and resulting in ashfall over nearby communities. The Philippine Institute of #volcanology and Seismology raised the Alert Level to 1.

Magma supply rate (Volcanology 🌋)
The magma supply rate measures the production rate of magma at a volcano. Global magma production rates on Earth are about 20–25 cubic kilometres per year.
National Institute of Geophysics and Volcanology (Italy): DANTE, the database that tells the story of over 2500 years of eruptions, is online. “The National Institute of Geophysics and Volcanology (INGV) just published DANTE, the database that collects and systematizes over 2500 years of eruptive history of Etna, one of the most active volcanoes in the world. DANTE (Database of Etna’s […]
Scientists puzzled by Earth's 'heartbeat' that causes slight tremors every 26 seconds
All explanations including ocean waves, volcanoes, and fractured sediments have been ruled out, leaving the mystery behind seismic tremors every 26 seconds unsolved.

Tornillo event (Volcanology 🌋)
A tornillo event is a low-frequency seismic event associated with volcanoes. The term, which means "screw" in Spanish, was coined in the mid-1990s at the Observatorio Vulcanológico y Sismológico de Pasto in Pasto, Colombia to describe seismic events seen at the Galeras volcano. A tornillo has the following characteristics that distinguish it from other seismic events: very li...

Dispersal index (Volcanology 🌋)
Dispersal index is a parameter in volcanology. The dispersal index D {\displaystyle D} was defined by George P. L. Walker in 1973 as the surface area covered by an ash or tephra fall, where the thickness is equal or more than 1/100 of the thickness of the fall at the vent. An eruption with a low dispersal index leaves most of its products close to the vent, forming a cone; an ...
