On July 30, 2025, at 11:24 a.m. local time, a magnitude 8.8 earthquake struck off the east coast of Russia's Kamchatka Peninsula, generating a Pacific-wide tsunami. Although this powerful earthquake was tied as the sixth strongest ever recorded by seismometers, the tsunami was weaker than initially feared, and the impact in terms of loss of life was minimal. In this episode, we examine how effective planning and warning systems helped minimize casualties. We also debunk a myth about a "parade of erupting volcanoes" and share essential tsunami safety information – all while doing our best to pronounce some beautifully complicated place names.
