Flat ocean

I like this app, but really an earthquake map should show the topography of the ocean floor, not leave it blank as though we are looking at the top of the ocean at sea level. When there’s an earthquake on a mid-ocean ridge I want to be able to exactly where it was in relation to other ridges or junctions or subduction zones. This app is missing details of 2/3 of the world. Please update to include the ocean floors because I do like this app, and would like to give it more stars

Great interactive map

I live in CA, and my family is scattered throughout the state. I original got this so I could track the activity of their area, but the map is so much fun to use that I've started monitoring other areas of the world too. The ring of fire is particularly interesting to keep an eye on.

It's good to stay educated in the world around you. I've learned that Californa is not at all the worst place to live in regards to earthquakes! Stay safe out there.

My favorite part about the map is the global 3d sphere. It's really easy to jump around to different locations and review the quakes. I love the map is not politically divided - it's all topho (at least that's how I keep my settings). As you zoom in, the state/country dividers pop up, but when you zoom out, they fade away which I love. Or you can select plate boundaries to be toggled on, which is pretty sweet too look at. Great app. Definitely learning more about the world.

Could be better

I really like the app but..,
My number one complaint: print is so small I can’t even read it with a magnifying glass! It’s basically guessing the general area when I look at map. Enlarge by at least 6!
Secondly: I’d love to see ocean’s topography!!
