We use the horizontal components of land-based seismometers in the vicinity of shorelines to apply to meteotsunamis the deconvolution algorithm introduced by Okal (Pure Appl Geophys 164:325–353, 2007) in order to recover time series of tsunami amplitudes from seismic recordings. For a selected set of seven such events recorded at 16 seismic stations, we obtain equivalent wave amplitudes and horizontal polarizations, the latter expressing the directions of particle motions at the surface of the sea. Our amplitudes are generally on the same order of magnitude as available regional records or reports, and the direction of tsunami currents is found mostly parallel to the relevant shorelines. In particular, seismic records available at three Spanish stations suggest that the unexplained waves which killed twelve people in Mostaganem, Algeria in 2007, had a meteorological origin. Our results, of an exploratory nature, suggest that seismic records could play an important role in the further understanding of the structure of meteotsunamis.

为了恢复地震记录中海啸振幅的时间序列，我们使用海岸线附近的陆地地震仪的水平分量将海啸应用到由Okal（Pure Appl Geophys 164：325–353，2007）引入的海啸解卷积算法中。对于在16个地震台站记录的七个此类事件的选定集合，我们获得了等效的波幅和水平极化，后者表示了海面粒子运动的方向。我们的振幅通常与可用的区域记录或报告处于相同的数量级，并且发现海啸流的方向基本上与相关海岸线平行。特别是，西班牙三个站点的地震记录表明，无法解释的海浪在2007年杀死了阿尔及利亚莫斯塔加涅姆的12人，有气象起源。我们的研究结果具有探索性，表明地震记录在进一步理解海啸结构方面可能发挥重要作用。
