"Since the eruption, seismic activity has dropped to low levels and there has been no further eruptive activity. However, we are still observing localised steam and mud jetting from the active vent area," said the bulletin.
"Over the next 24 hours we estimate an equal likelihood of either no eruption or a smaller/similar sized eruption that would impact the main crater floor. There is a high level of uncertainty associated with this estimate. We also estimate the least likely scenario is a larger eruption. There is an extremely low likelihood of any ash impact to the mainland, but gas may be smelt depending on the prevailing wind direction."
