Magnitude, frequency and climate forcing of global volcanism during the last glacial period as seen in Greenland and Antarctic ice cores (60–9 ka) [PDF]

Climate of the Past, 2022
Large volcanic eruptions occurring in the last glacial period can be detected by their accompanying sulfuric acid deposition in continuous ice cores. Here we employ continuous sulfate and sulfur records from three Greenland and three Antarctic ice cores ...

Tambora 1815 as a test case for high impact volcanic eruptions: Earth system effects [PDF]

, 2016
The eruption of Tambora (Indonesia) in April 1815 had substantial effects on global climate and led to the ‘Year Without a Summer’ of 1816 in Europe and North America. Although a tragic event—tens of thousands of people lost their lives—the eruption also

Hydrological and Chemical Budgets of Okama Crater Lake in Active Zao Volcano, Japan

Hydrology, 2022
The Okama Crater Lake is located in the highly active Zao Volcano on the boundary of Miyagi and Yamagata Prefectures, Japan. At present, the lake stays relatively calm with neither bubbling, steaming nor gas smell at a pH of 3.2–3.4, though the lake did ...

Pyroclastic deposits and volcanic history of Mayor Island [PDF]

, 1981
The emergent summit of Mayor Island, Bay of Plenty, New Zealand, is a peralkaline rhyolite volcano constructed by: a sequence of lava flows, the Tutaretare Rhyolite Formation new; and pyroclastic deposits, the Oira Pyroclastite Formition (new).

Potential for crustal deformation monitoring using a dense cell phone carrier Global Navigation Satellite System network

Earth, Planets and Space, 2022
Monitoring of crustal deformation provides essential information for seismology and volcanology. For such earth science fields and other purposes, various Global Navigation Satellite System (GNSS) networks have been constructed at the national and ...

Volcanic eruptions from ghost magma chambers [PDF]

, 2008
Recent studies have proposed that magma reservoirs crystallized to a virtually rigid crystal-mush can be partially remelted by diffusion of hot fluids. We show that for a crystal mush with the composition of a K-trachyte from the Campanian Ignimbrite (CI)

Assessment of directional accuracy of GNSS-Acoustic measurement using a slackly moored buoy

Progress in Earth and Planetary Science, 2019
We assessed the positioning accuracy of GNSS-Acoustic (GNSS-A) measurement using a slackly moored buoy. A key feature of real-time buoy-based GNSS-A measurement is that positioning must be performed via single ranging from an arbitrary observation ...

Detecting volcanic sulfur dioxide plumes in the Northern Hemisphere using the Brewer spectrophotometer, other networks, and satellite observations [PDF]

, 2016
This paper demonstrates that SO 2 columnar amounts have significantly increased following the five largest volcanic eruptions of the past decade in the Northern Hemisphere.

Evaluation of the favorability of faults to slip: the case of the 2024 Noto Peninsula earthquake

Earth, Planets and Space
The 2024 Noto Peninsula earthquake (M 7.6) occurred at a depth of approximately 15 km in the eastern part of Noto Peninsula. The high dip angle faults (50–60°) in this area were formed by the extensional stress field during the formation of the Japan Sea.

The Influences of Tropical Volcanic Eruptions with Different Magnitudes on Persistent Droughts over Eastern China

Atmosphere, 2020
In this study, the influences on persistent droughts over Eastern China from tropical volcanic eruptions with three categories of magnitudes, i.e., 25 Tg, 50 Tg, and 100 Tg, were investigated through three groups of volcanic sensitivity experiments based
