\begin{abstract}
Meteotsunamis triggered by atmospheric disturbances of Lamb waves due to
the 2022 Hunga Tonga volcanic eruption were observed in coastal areas
surrounding the Pacific Ocean. However, the spatio-temporal evolution of
the meteotsunami wavefield remain elusive due to the lack of geophysical
observations in the ocean. Here, we show a detailed distribution of the
propagation velocities and directions of the meteotsunamis in the
bathymetric slope area between the Japan Trench and nearshore, using 150
absolute pressure gauges deployed at water depths of 100--8000 m. We
also illuminate the generation of free waves, i.e., tsunamis, which
occur when the meteotsunamis propagate at the slope area. Large
amplitudes of the meteotsunamis are produced in the southern part of the
slope area, which is caused by the relationship between the incoming
direction and the gradient of the bathymetry. Our findings establish a
link between seafloor pressure measurements and the Lamb wave-excited
wavefields.%
