Enjambre sísmico?

Enjambre sísmico?
 

What would be a good translation for enjambre sísmico?

seismic 'cluster' / 'swarm' ? I can't think of the English saying that we would use, hmmm seismic activity, not quite is it? nope nothing coming to me

Thanks for any suggestions

seismic swarm
earthquake swarm

I'd think of "seismic cluster" as the closest...

Never heard the Spanish expression before... (Do you have more context for it?)

Yes, a cluster or a surge could be used, since both figure in the definition of a seismic swarm.

I'm supposing the Spanish translation is a literal translation of seismic swarm.

Thanks guys, seismic swarm must be the one, for some reason I haven't heard this phrase in English or it hasn't registered when I have. Gracias por la ayuda como siempre :)
