Unsupervised Anomaly Detection for Volcanic Deformation in InSAR Imagery

open access: yesEarth and Space Science
Satellite‐based Interferometric Synthetic Aperture Radar (InSAR) images have the potential to detect volcanic deformation prior to eruptions, but while a vast number of images are routinely acquired, only a small percentage contain volcanic deformation ...

How satellite InSAR has grown from opportunistic science to routine monitoring over the last decade

open access: yesNature Communications, 2020
In the past decade, a new generation of radar satellites have revolutionised our ability to measure Earth’s surface deformation globally and with unprecedented resolution.

Nearly Three Centuries of Lava Flow Subsidence at Timanfaya, Lanzarote

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The 1730–1736 eruption on Lanzarote was one of the most significant volcanic eruptions to occur on the Canary Islands, with lavas covering over 200 km2.

The Great Comet and Schmidt's Comet [PDF]

open access: yesNature, 1882
THERE can be no doubt of the elongation of the nucleus of the Great Comet in the direction of the axis of the tail, in which direction it is three times as long as in a direction at right angles thereto.

Systematic satellite observations of the impact of aerosols from passive volcanic degassing on local cloud properties [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
The impact of volcanic emissions, especially from passive degassing and minor explosions, is a source of uncertainty in estimations of aerosol indirect effects.

Near-Earth Asteroids as Possible Parent Bodies of Meteor Streams [PDF]

open access: yesУчёные записки Казанского университета: Серия Естественные науки, 2016
The genetic relationship of meteor streams with near-Earth asteroids (NEAs) is being actively studied. A genetic link with the asteroid is possible only for streams in which meteoroids have the geocentric speed smaller than 50 km/s, thereby meaning the ...

Are the main belt comets, comets? [PDF]

open access: yesProceedings of the International Astronomical Union, 2009
AbstractWe present the visible spectrum of asteroid-comet transition object 133P/Elst-Pizarro (7968), the first member of the new population of objects called Main Belt Comets (Hsieh & Jewitt 2006). The spectrum was obtained with the 4.2m William Herschel Telescope at the “Roque de los Muchachos” observatory.

Observing eruptions of gas-rich compressible magmas from space

open access: yesNature Communications, 2016
Satellite observations are an important tool in volcano monitoring, but observations such as ground deformation and gas emissions are treated independently. Here, the authors present a model coupling them through their link to magma volatile contents and
