Ireland was hit with two jolts last night as Tonga's volcanic eruption rippled across the world.
While not noticeable from above ground, Irish weather stations were able to pick up the wave which was travelling at close to 1,100 kilometres per hour.
The first wave was felt around 7pm with the second at 2am - although it wouldn't be significant enough to wake anyone up.
Met Eireann have shared images from their weather stations in Mullingar and Valentia where you can see the wave having an impact.
Ireland however has nothing to worry about when it comes to the Tonga Volcano, something that can't be said for the west coast of the US.
Parts of the country are under a tsunami warning after the volcanic eruption in the South Pacific.
The impacts of the tsunami have begun hitting the West Coast as officials warned of unpredictable currents, waves and tides, which could endanger swimmers and boats at sea.
The eruption occurred over 8,000 kilometres away from the majority of locations on the West Coast near Tonga.
The tsunami caused people to rush to higher ground and caused communication with the nation to be disrupted.
A tsunami advisory is in effect for Hawaii, Alaska and the U.S. Pacific coast as officials urge people to avoid beaches and marinas.
In Southern California, beaches and piers were closed as a precaution due to possible strong rip currents.
However, the National Weather Service said there were "no significant concerns about inundation."
The first waves arrived before 9 a.m. on the southern Oregon coast and measured over one foot tall, while California's central coast saw waves of up to 2.5 feet. Higher waves are expected to arrive later in the day.
The National Weather Service warned people to stay away from harbours and not go to the coastal destinations to watch the tsunami.
