Is this big enough to produce a Tsunami? Apparently maybe only a small localised one, but I'm supposed to be getting the ferry from Lombok to Bali shortly and two of those have already burnt down the last 2 weeks!

A ferry in the open ocean is one of the safer places to be during a tsunami. Remember, it's not a surf-style wave, but a gradual increase in water level.
After the tsunami, would the current induced by the water drawback disrupt the ferry ability to come back ? I wonder if the ocean “rise” again (water on top of water) or if it’s more a current-style (water push water) movement.
boarding the ferry may not be the most pleasant, however.
Indonesia's tsunami bulletins appear to be here:
https://rtsp.bmkg.go.id/publicbull.php
They've declared the event over - some waves were generated but nothing particularly large. Bulletin 3 for the recent quake includes wave height observations - maximum reported was 94cm; most were under 50cm.
Tsunamis are only an issue close to shore. In the ocean it's barely a mild wave.
In a boat going further out is the safest thing you can do if there's a tsunami warning.
Depends on how the tsunami was created. By earthquake or by land slide. For example, the following tsunami no boat is safe.

That's a hypothetical "hazard" of a megatsunami and on top of that, seems reaaaally unlikely to happen within the lifetime of any of us:
> Giant landslides are rare events.[117] Humanity has never witnessed enormous collapses on La Palma[59] and there is evidence that the western flank of La Palma is currently stable[65] and a collapse in the near future is unlikely.[133] A worst-case scenario giant landslide like the one modelled by Ward and Day 2001 is a very low probability event, probably much less common than once per 100,000 years[123]
But, never say never, apparently we're ruining the planet faster than anyone of us thought possible just 50 years ago, so who knows what could happen.
Safer than going inland..?
There have been 70m tsunamis and lakes get tsunamis too, so… maybe?

I've seen "possible tsunami" pre-warnings, and a sea level gauge at/near Lembar showing sea level oscillations - so I would recommend keeping a close watch on some information source that's better than HN comment threads, yes.
Correct, but also, I’d bet there is a lurking tsunami expert here somewhere. Nothing is ever too niche for HN.
There's a tsunami warning list you can sign up for. As well as global earthquake alerts. In my experience they arrive very quickly
Usually earthquakes on land don't trigger tsunamis but are more damaging locally
I would upgrade the ferry and make sure to get a high quality one given all the swell in the ocean already (most of bali had 6ft+ waves yesterday) and this incident. Not worth the risk.
Lombok will have lots of higher ground at least. You really just have to be careful on and near the beach.
Easily big enough, but how deep it was generated and how the movements happened do impact the risk a lot.
Safe travels, friend.
the tsunami risk is negligible compared to the fire risk
Agreed, currently aboard and on high alert, pray for me HN
Let us know you made it ok!
Interesting times for the ferry indeed
