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.
