Resumo | In this work, we focused on the survey of tsunamigenic variations in the vertical component (Z) and in the horizontal component (H) of the geomagnetic field using four spatiotemporal methods. Magnetic disturbances originated from ionospheric currents contain both horizontal and vertical components, however the vertical component is dominant in tsunamigenic magnetic signals observed on land. In this way, one can distinguish the former from the latter, and vice-verse. Here, we selected nine magnetic observatories that were influenced or more directly affected by the Maule (2010) tsunami event, which occurred during a very geomagnetically quiet period, i.e., without external influences. The continuous and discrete wavelet techniques have been used to identify the tsunamigenic magnetic disturbances, and together with the travel-time diagram (TTD) and mean absolute percentage error (MAPE) maps, these found tsunamigenic disturbances have been validated. These disturbances are found to have contributions from both oceanic and thermospheric currents which are arising from the tsunami forcing. The amplified N-shaped disturbances occurring instantly and with the time delay of 10-50 minutes from the tsunami arrival are attributed to be of the oceanic current and thermospheric current origin, respectively. These results suggest that these both kinds of tsunamigenic magnetic disturbances can be well-identified for the four spatiotemporal methods used here. |
