### 1/5 — La Palma

*2021-09-21*

REALLY disappointed. Wanted to check in earthquakes associated with volcanic eruption there and nothing was reported even though I know there were multiple ear quakes reported. Deleting this app……

### 3/5 — It dose it’s job. Just not well

*2018-06-30*

I just got this app and there was a 6.1 earthquake near Mexico on June 29 2018. Today is June 30 2018 so I expected to see a red dot near Mexico but it wasn’t there witch means this app isn’t the updated app. Then I refreshed it multiple times and it still wasn’t there. I checked other apps and they had the red dot near Mexico     So this is why I have to give this 3 stars compared to other apps, it dose it’s job. Just not very well.
