Earthquake!

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.

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.
