Can't be compared really - you get reports on incoming hurricanes a week in advance and you can follow its direction online, especially on American news outlets they give continuous updates (as they should) for people's safety and whether they should be evacuated, stuff like that. After that it's again major news when they make landfall, and the aftermath is also well documented.
An earthquake comes unexpected most of the times, and it's normal that we get more CNN coverage than say from Sulawesi for example. They are not prepared, there are barely any correspondants or news outlets present and it's harder to get access to the affected area. Anyway, the most recent earthquake and what happened after got plenty of attention imo, at least in Belgium media, what with the plundering going on and all of that stuff. The earthquakes that caused havoc in Lombok and Bali also got major coverage over here.
