Is it possible for a meteor to cause a chain of volcanoes to blow? like all the pressure under the crust gets rattled around?
On Mercury, it seems the impact that created the Caloris basin [1] may also have created a seriously busted-up region at its antipode (opposite on the planet from the impact) [2]. This may have happened due to shock waves propagating through Mercury's interior, focused by reflection at the planet's surface onto an area opposite the impact. There are alternate theories.
A few years ago, I looked into whether the Deccan Traps eruptions might have been either triggered or enhanced by similar antipodal seismic wave energy from the Chicxulub impact. Based on Earth's continental positions about 65M years ago, it seemed possible, maybe plausible. There were some papers discussing the possibility, but I don't have the data at hand.

Could it be worked backwards, there a re a number of flood basalts, some as recently as 10mya, is there any evidence of impacts for any others? Or is there some reason the Deccan traps stand out compared to the others?
But, unfortunately, just because we like something, doesn't mean it really went down that way. And rightfully so, a horde of nerds will come out of the woodwork, to inform us if we were to claim the validity of an event, without true evidence in hand.
Either way, it won't stop me from harboring a deep suspicion that this is exactly what happened.
Mostly, my own belief is founded in similar conceptual origins for the moon.
It's very human to want to connect these events into a cohesive narrative, but there is still the possibility that they were independent events in our universe.
