Formation of a rotating jet during the filament eruption on 10-11 April 2013

, 2015
We analyze multi-wavelength and multi-viewpoint observations of a helically twisted plasma jet formed during a confined filament eruption on 10-11 April 2013. Given a rather large scale event with its high spatial and temporal resolution observations, it

Strong persistent cooling of the stratosphere after the Hunga eruption

Communications Earth & Environment
The 2022 eruption of the Hunga volcano was a major event that propelled aerosols and water vapor up to an altitude of 53–57 km. It caused an unprecedented stratospheric hydration that is expected to affect composition, thermal structure, circulation and ...

Filament Activation in Response to Magnetic Flux Emergence and Cancellation in Filament Channels

, 2015
We make a comparative analysis for two filaments that showed quite different activation in response to the flux emergence within the filament channels. The observations from the Solar Dynamics Observatory (SDO) and Global Oscillation Network Group (GONG)

Seismicity rate before eruptions on Piton de la Fournaise volcano: Implications for eruption dynamics

Geophysical Research Letters, 2003
Individual eruptions are difficult to foresee using daily seismicity at Piton de la Fournaise (PdlF) volcano, except within a few hours from the eruption time. However, when using a superposed epoch analysis for all of the 15 eruptions in the 1988–2001 period, we find that the seismicity rate increases 2 weeks before the eruption time as (t) ∼ (te − t)−

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

New insight into the 2011-2012 unrest and eruption of El Hierro Island (Canary Islands) based on integrated geophysical, geodetical and petrological data

Annals of Geophysics, 2015
A shallow water eruption started on October 10, 2011, ~2 km south off the coast of El Hierro (Canary Islands, Spain). The eruption lasted about five months and ended by early March 2012.

Two Energy Release Processes for CMEs: MHD Catastrophe and Magnetic Reconnection

, 2007
It remains an open question how magnetic energy is rapidly released in the solar corona so as to create solar explosions such as solar flares and coronal mass ejections (CMEs).
