There is a little plus sign you might see on your cursor if you are on a computer or other media and the cursor is over the map. If you click with the plus sign over by where the lava is entering the ocean you can see quite clearly where the old coastline used to be.

We also visited Pahoa and my friends I was snorkeling with played a concert for people in Hilo while we were there too.
