Tremors were felt on all adjacent islands.

As you can see from these tweets, there are at least three reports of ground failures. If there are many such messages and everything is confirmed, this will be a very bad sign for the islands.
Since the epicenter is at the sea, a tsunami is expected. So far, waves of not more than 50 cm are reported:

Lost communication with one of the buoys in the epicenter area. Perhaps a technical malfunction, perhaps a very large wave.
The trigger for the earthquake most likely was yesterday’s gamma-ray burst:
