Spontaneous Transient Summit Uplift at Taftan Volcano (Makran Subduction Arc) Imaged Using an InSAR Common‐Mode Filtering Method

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We unambiguously document unrest at Taftan volcano. Summit uplift was detected using Interferometric Synthetic Aperture Radar time series and its timing tightly constrained applying a new common mode filtering method. Uplift started and ended gradually lasting 10 months (July 2023 to May 2024).

Accurate hindcasting of explosive eruptions at Whakaari, New Zealand

Volcanica
Phreatic eruptions are small, sudden events, commonly with few precursory signals. They are driven by interactions between magmatic and hydrothermal processes at shallow levels beneath the surface.

Aquagene volcanism in the Tasmanian Tertiary, in relation to coastal seas and river systems [PDF]

, 1980
Tertiary aquagene volcanics at over forty localities in Tasmania concentrate in three main regions. The North West Coast - Bass Strait islands examples are mostly related to Miocene high seas.

Precursory tilt changes of small phreatic eruptions of Meakan-dake volcano, Hokkaido, Japan, in November 2008

Earth, Planets and Space, 2015
Although forecasting an occurrence of phreatic eruption is very difficult, it has been reported that some precursory activities often precede these eruptions at several volcanoes.

Characterizing Spatiotemporal Ground Deformation at Whakaari (White Island) Volcano, New Zealand From 2014 to 2024 Using InSAR Time‐Series Analysis

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract Whakaari (White Island) volcano is the most active volcano in New Zealand with a dynamic hydrothermal system. The volcano has had four eruptive periods since 2014. In this study, our aim is to understand the pre‐and post‐eruption deformation processes occurring at Whakaari using interferometric synthetic aperture radar (InSAR).

An Overview of the Dynamics of the Volcanic Paroxysmal Explosive Activity, and Related Seismicity, at Andesitic and Dacitic Volcanoes (1960–2010)

Frontiers in Earth Science, 2018
Understanding volcanic paroxysmal explosive activity requires the knowledge of many associated processes. An overview of the dynamics of paroxysmal explosive eruptions (PEEs) at andesitic and dacitic volcanoes occurring between 1960 and 2010 is presented

The 2018 phreatic eruption at Mt. Motoshirane of Kusatsu–Shirane volcano, Japan: eruption and intrusion of hydrothermal fluid observed by a borehole tiltmeter network

Earth, Planets and Space, 2021
We estimate the mass and energy budgets for the 2018 phreatic eruption of Mt. Motoshirane on Kusatsu–Shirane volcano, Japan, based on data obtained from a network of eight tiltmeters and weather radar echoes.

Re-evaluation of the history of phreatic eruptions from Atosanupuri Volcano, eastern Hokkaido, Japan:: Inferred from 14 C ages and borehole cores of Japan Meteorological Agency@@@炭素年代および気象庁ボーリングコアからの検討

, 2017
Atosanupuri Volcano is one of the active volcanoes, located in the Akan–Shiretoko Volcanic Chain, eastern Hokkaido. Tephro-strati-graphic and tephro-chronologic studies were conducted on two drill cores and new outcrops around the volcano to reveal a ...

Imaging the hydrothermal system beneath the Jigokudani valley, Tateyama volcano, Japan: implications for structures controlling repeated phreatic eruptions from an audio-frequency magnetotelluric survey

Earth, Planets and Space, 2015
This study focuses on the results of an audio-frequency magnetotelluric (AMT) survey across the Jigokudani valley, Tateyama volcano, Japan, to investigate the spatial relationship between the distribution of electrical resistivity and geothermal activity
