Amos vs Hosea

They were both prophesying in 760 BC.  The chart says they were both prophets to Israel.  I find the style of writing a bit hard to understand in the prophets.  But the thing that I do notice is that the prophecies of Amos seem to be more general and the prophecies of Hosea are aimed squarely  at Israel. 

In both cases God is ticked off at the people.  In Amos the grievances include many different nations including Israel and Judah.  In Hosea the focus is entirely on Israel.
