The Tonga Eruption Was So Powerful it Disrupted Satellites Half a World Away - by spacewriter
EPBs form when plasma, electric fields, and neutral winds move through the ionosphere. Essentially, these bubbles are localized density gradients of plasma. Atmospheric waves disturb them. Since the volcanic blast created such a wave, the team theorized that a volcanic eruption is a trigger. The Hunga Tonga-Hunga Ha’apai event was essentially a “volcanic hammer”. It pounded ten cubic kilometers of rock out in the form of ash and sediment from beneath the ocean waves.
They also spotted something unusual. “Our new finding is that the ionospheric disturbances are observed several minutes to hours before the initial arrival of the shock waves triggered by the Tonga volcanic eruption,” Shinbori said. “This suggests that the propagation of the fast atmospheric waves in the ionosphere triggered the ionospheric disturbances before the initial arrival of the shock waves.
