Earthquake!

We exhaust our repertoire of tectonic plate jokes while introducing the following topics: the earth’s layers, what are tectonic plates, three types of plate boundaries, plate boundaries vs faults, and how earthquakes happen.

This is a brief overview to lay the groundwork. (… pun intended!) Future episodes will dive deeper.

INTERACTIVE LESSON We explain how to use the QuakeFeed app to locate plate boundaries and faults on the Quake Map. Download QuakeFeed from the App Store

ASK THE SCIENCE KID We answer an interesting question about earthquakes in Antarctica.

Our goal is to inspire CURIOSITY!

We hope you and your family enjoy our lighthearted humor while learning something new about this AWESOME planet we call home.

*NOT A FULL EPISODE* Just a quick announcement about QuakeFeed v5.1.0, available now in the App Store. This update adds three new features: USA Wildfires, Map Legend, and Aftershock Forecasts.

The USA Wildfires data layer requires a QuakeFeed Premium subscription. While viewing the map, tap on a wildfire symbol to view detailed information, such as: acres burned, percent contained, how many buildings were destroyed, how many firefighters are fighting it, etc.

The Map Legend and Aftershock Forecasts features are included in the free / ad-supported version. You will find the Map Legend button in the top right corner of the map. The USGS Aftershock Forecasts are linked in Quake Details. NOTE: The USGS only publishes aftershock forecasts for larger earthquakes. These quakes will include the words “Aftershock Forecast” in the Quake List, to let you know that it is available.

Next month, we will add more more wildfire features to QuakeFeed Premium, such as wildfire alerts and a wildfire list view.

We hope to get back to full podcast episodes soon. We have been coping with a family medical emergency for the past several months. Thank you for your patience and understanding.

We hope you enjoy QuakeFeed v5.1.0. If you have any questions, concerns, or feedback, please tap the ? in the top right corner of QuakeFeed then tap Ask to send us a support email.

You’ll laugh, you’ll cry, you’ll learn how to protect yourself in an earthquake!

When the shaking starts, what should you do? We use a bit of humor to help you remember that Drop, Cover and Hold On reduces your chance of injury in an earthquake. We also dispel some common myths about earthquake safety. We hope you enjoy. Stay safe!

Linda and Sequoya travel through time to April 14, 1906 and visit San Francisco. They ride a cable car down Market Street and see a bustling, prosperous city. Next, they travel forward four days and witness the 1906 San Francisco Earthquake. The devastating M7.9 quake and the fire that followed took 3,000 lives and destroyed 80% of the city. It also marked the dawn of modern scientific earthquake research in the United States.
