This study presents the analysis of seismic signatures generated during passage of hurricanes Newton (September 2016) and Willa (October 2018), recorded on the daily helicorders of a short-period seismic station at the distances about 450 km from the tracks of events. This view from seismic station allowed to obtain the following results. Periods of passage of these tropical storms and hurricanes were identified. Analysis of the dynamics of sequences of these seismic signals allowed to separate the time intervals of increase and decrease in the development of atmospheric disturbances. The spectral analysis of the signals of tropical storm Newton and hurricane Willa showed that the spectral amplitudes of signals, recorded during the maximum stage of activity of the tropical storm, were larger than the same for the maximum stage of activity of the hurricane. This may be related to the presence of intensive hailstorms during tropical storm.
