Geometric estimation of volcanic eruption column height from GOES-R near-limb imagery – Part 1: Methodology
Autor: Á. Horváth, J. L. Carr, O. A. Girina, D. L. Wu, A. A. Bril, A. A. Mazurov, D. V. Melnikov, G. A. Hoshyaripour, S. A. Buehler
Publikováno v: Atmospheric Chemistry and Physics, Vol 21, Pp 12189-12206 (2021)
A geometric technique is introduced to estimate the height of volcanic eruption columns using the generally discarded near-limb portion of geostationary imagery. Such oblique observations facilitate a height-by-angle estimation method by offering clo

Geometric estimation of volcanic eruption column height from GOES-R near-limb imagery – Part 2: Case studies
Autor: Á. Horváth, O. A. Girina, J. L. Carr, D. L. Wu, A. A. Bril, A. A. Mazurov, D. V. Melnikov, G. A. Hoshyaripour, S. A. Buehler
Publikováno v: Atmospheric Chemistry and Physics, Vol 21, Pp 12207-12226 (2021)
In a companion paper (Horváth et al., 2021), we introduced a new technique to estimate volcanic eruption column height from extremely oblique near-limb geostationary views. The current paper demonstrates and validates the technique in a number of re

SQUEEZING OUT PLASTIC LAVA BLOCKS ON YOUNG SHIVELUCH VOLCANO (KAMCHATKA) IN 2020–2021
Autor: A. Yu. Ozerov, O. A. Girina, V.A. Tsvetkov, Seismology Feb Ras, Yu. V. Demyanchuk
Publikováno v: Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, Vol 51, Iss 3, Pp 77-83 (2021)
Volcano Young Sheveluch is one of the most active volcanoes in Kamchatka. Since August 1980 to the present time, an extrusive dome has been growing in the crater of the volcano. Plastic lavas in the form of large ribbons were noted on the dome alread

Classification of Video Observation Data for Volcanic Activity Monitoring Using Computer Vision and Modern Neural NetWorks (on Klyuchevskoy Volcano Example)
Autor: Igor Urmanov, O. A. Girina, Aleksandr Kamaev, Sergey Korolev, A. A. Sorokin
Publikováno v: Remote Sensing; Volume 13; Issue 23; Pages: 4747
Remote Sensing, Vol 13, Iss 4747, p 4747 (2021)
Currently, video observation systems are actively used for volcano activity monitoring. Video cameras allow us to remotely assess the state of a dangerous natural object and to detect thermal anomalies if technical capabilities are available. However

2016 volcano eruptions in Kamchatka and the Northern Kuriles and their danger to aviation
Autor: Elena Petrova, O. A. Girina, Dmitry Melnikov, A. G. Manevich, A. A. Nuzhdaev
Publikováno v: Вулканология и сейсмология. :34-48
Strong explosive volcanic eruptions are extremely dangerous to the modern jet aircraft as they can produce several cubic kilometers of volcanic ash and aerosols that can be sent to the atmosphere and the stratosphere in several hours to several days
