I was volunteering in Tohoku.
I'm living by myself in Tohoku now.
A magnitude 8.9 earthquake slammed into Japan’s northeastern coast.
The East North is also known as the Northeast. But, it's not just the Northeast, it's a region as well. You may have heard of the Tohoku Region before? It was the one hit by the 2011 Tohoku Earthquake.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
