A tsunami advisory was issued for the US West Coast on April 5, 2024, due to volcanic activity in Tonga. On the same day, a magnitude 4.8 earthquake occurred off the East Coast, but no tsunami warning, advisory, watch, or threat was issued. Additionally, a video circulating on social media, which was initially believed to show a woman taking a selfie during a tsunami, was later determined to be a tidal bore event in Indonesia, not a tsunami.
