  • 1960 Valdivia Earthquake – The Largest Ever Recorded

    On May 22, 1960 at 3:11 p.m. local time, a magnitude 9.5 earthquake struck the coast of southern Chile. It was the largest earthquake ever recorded and what followed was not a single disaster but a cascade: tsunamis, landslides, flooding, and a volcanic eruption.

  • 2025 Kamchatka Peninsula Earthquake

    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.

  • 2019 Ridgecrest Earthquake Sequence: An Independence Day California Won't Forget

    On July 4, 2019, a magnitude 6.4 earthquake struck near Ridgecrest, a town in California's Mojave Desert. Thirty-four hours later, a magnitude 7.1 earthquake hit the same area – the largest to strike California in 20 years. Shaking was felt across California, Arizona, and Nevada. The earthquakes killed one person, injured 25, and caused surface ruptures stretching 30 miles with ground displacement exceeding six feet. Total damage exceeded $5.3 billion.

    Learn about the impact of the Ridgecrest earthquakes and how they became a case study for understanding earthquake cascades and stress transfer between intersecting fault systems. We'll also share an important message about safety and preparedness.
