Characterization analysis of multi-source parameters from satellite and
ground data in the 2022 Tonga Volcanic Eruption
Abstract
The Tonga volcano erupted with a mass of energy released into the plate
and atmosphere, causing the variations of the relevant geophysical
parameters. Thus, we creatively apply the observations from space-borne
and ground-based sensors to reveal the characterizations of up to four
items (tropospheric response, sea surface temperature, plate movement,
and ionospheric reaction). The results of precipitable water vapor from
space-borne and ground-based data show that tropospheric response has a
trend of rising first, after volcano event dropping sharply, then
recovering to a normal level. The examination of ground-based GNSS
station coordinates illustrates that plate movements up to 20 dm are
caused by volcano eruption. Eventually, for the ionospheric reaction a
similar characterization is found as the tropospheric response through
total electron content variation. These are the first comprehensive
analyses showing the impacts of the Tonga volcano on multiple types of
parameters from both space-borne and ground-based data.
