Olive Tree Problem

[Jmjoffrion]

Can someone comment on what might be wrong with our olive trees? They are about 8 years old and just started dropping leaves and becoming sparse. This spring, they started growing clumps of tiny leaves. Some on the trunk and some writhing the canopy branches. I’m not convinced it’s gall as they are not woody growths but diminutive leaves.

Not much help but I'm guessing it's a kind of virus having seem similar on trees here in Britain.
