Can an Antarctic ice sheet collapse cause a worldwide tsunami?

[NealM]

Hi,

I am not a Physical Student/Physical Scientist.
Can an Antarctic ice sheet collapse cause a worldwide tsunami? A big one or bigger like this: https://www.theguardian.com/world/2021/feb/26/iceberg-size-of-greater-london-breaks-off-antarctica

Can you please explain why this can cause a worldwide tsunami or why not ?

Research done but for me it is still not clear if an Antarctic ice sheet collapse can cause a worldwide tsunami.

Welcome to PF.
The large parts of the icecap that break away are floating in the seawater before the break. Since there is no sudden change in displaced volume, there will be no tsunami generated.

The land mass is not polished like a slide, so the icecap fits the landscape profile well. The speed of movement is determined by the rate of melting and refreezing of the bottom of the ice cap. No sudden movement is possible.

Here is a collapse that took several years:
