The Democratic Tsunami was/is(?) more of a pure action based protest group lead by an anonymous leader structure. The leaders were/are probably certain leader figures within the independence seeking community; but that is just a speculation on my part.
Its biggest action was probably at the Barcelona Airport in October 2019, a protest a couple of years after the Catalan independence election in October 2017. The election itself was deemed unconstitutional by the Spanish government. The registered voters/turnout of this election was 43.03%; where 92.01% voted for separation from Spain and 7.99% voted to stay within Spain –– see: https://en.wikipedia.org/wiki/2017_Catalan_independence_refe... –– but this was not a normal election by any means (read the link for more).
Typically the ANC –– see: https://en.wikipedia.org/wiki/Assemblea_Nacional_Catalana –– has been the leading organization in the independence movement. They have been organizing big independence rallies etc. and the actions has been peaceful (from what I've read and seen). The Democratic Tsunami based protests were different in this regard, where more direct confrontation was more the norm. From what I have read Democratic Tsunami is not particularly active at the moment, but of course this might change.
