QuakeFeed version 6.6.2 is now available in the App Store. This update contains a new feature that we're excited about because it brings us closer to our goal of making the QuakeFeed community the smartest, most knowledgeable group of earthquake nerds on the planet!

Have you ever noticed the small icons in the QuakeFeed earthquake list? Here are some examples:

These icons indicate that there are links to additional information about this event on the earthquake details screen. In the episode, we explain what each icon means, and what to do when you see them.

Join Linda and Sequoya as they introduce QuakeFeed v6.5.8, a bug fix update that brings back a fan favorite: Dad Jokes!

For a limited time, we've replaced the ads in the earthquake list with holiday-themed humor. Earthquakes are serious – it's true – but your earthquake app doesn't have to feel bah humbug all the time. And you never know when a terrible pun might come to your rescue at a family gathering.

Not a dad joke fan? (cough Scrooge! cough) QuakeFeed Premium subscribers can turn them off and enjoy a completely joke-free experience.

Download QuakeFeed from the iOS App Store to track earthquakes, wildfires, and volcanoes – now with a side of family humor.

In this episode, we begin with Hurricane Melissa, which made landfall in Jamaica on October 28th as a Category 5 storm and then tore a path of destruction through the Caribbean. If you would like to help support disaster response and recover, please visit Charity Navigator. There you can find highly rated organizations that are helping those impacted by Hurricane Melissa.

Then we continue with a QuakeFeed status update. We share our plan and timeline for the next few QuakeFed app updates – including how and when we plan to support iOS 26. We also talk about new content we creating, such as the On This Day in Earthquake History series. We close with a few words about why we think learning about historical earthquake events is important and helpful.

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.

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.

On June 29, 1925, at 6:44 a.m., a magnitude 6.8 earthquake struck Santa Barbara, California, killing 13 people and damaging 85% of its downtown buildings. Three brave and quick-thinking utility workers immediately cut power and gas to the entire city, preventing widespread fires, saving lives, and shielding Santa Barbara from further destruction.

This gave engineers and seismologists a rare laboratory for studying seismic damage without fire obscuring the destruction patterns. What they learned led Santa Barbara to adopt comprehensive seismic building codes. But the city didn't just build back safer. By mandating both earthquake-resistant construction and a unified Spanish Colonial Revival style, Santa Barbara was reborn as an iconic coastal destination.
