The new Earthquake Map/List pages are slower than the older generation earthquake maps (recenteqs) because they provide additional benefits to viewing and interacting with the earthquake data.

If you are using a mobile device to view the earthquake pages, or have limited bandwidth, here are a few steps you can take to improve your experience using the interface:


The 4 icons in the top right corner toggle the following content in and out of view:


The list is loaded by default the first time you open the interface. The list can be toggled in and out of view by clicking on List in the top right corner. The list provides the least resource intensive method for viewing earthquakes. The list loads all earthquakes from the currently selected feed (Settings > Earthquakes), and by default shows the most recent earthquake first (Settings > List Sort Order).



To show (or hide on desktop) the map, click Map in the top right corner. Earthquakes from the currently selected feed (Settings > Earthquakes) are loaded onto the map.

Known Bugs

There are a few bugs that we are currently aware of:

Browser Crashes
If your browser crashes, it's probably because you're trying to view too many earthquakes. See our disclaimers for tips on how to avoid crashing a resource strapped device.
