The science of volcanoes and their relationship with the climate is hard to keep up with. Why do some volcanoes give us little warning before they blow? Are we ignoring the next big eruption?

The St Vincent eruption shows that preparedness and early anticipatory action can avert a volcanic disaster!
Today marks the 4th anniversary of the explosive phase of the 2020-2021 St Vincent eruption. Effective monitoring, good coordination, extensive education campaigns and efficient communications contributed to the successful evacuation of over 20,000 people with no recorded deaths.

Now that it's thought the sesimic activity around Santorini is caused by magma, authorities plan an emergency port. Important to note that the vast proportion of magmatic unrest on volcanoes doesn't lead to eruptions, but preparation is key in cases where they might.

It does look like the Washington VAAC (Volcanic Ash Advisory Center) is still up and issuing alerts, but if that stops ... ho boy, that could get messy. The VAAC is a NOAA operation.

This effectively ends all nsf-funded disaster research.
NSF is still freezing grants and reviewing for potential clashes with trumps edicts: terms such as“broadening participation” language, foreign assistance, climate science, domestic energy” all flagged. This is insane, career wrecking and damaging for quality science 😡🧪
Exclusive: how NSF is scouring research grants for violations of Trump’s orders
The US National Science Foundation has unfrozen grant funding, but it continues to scrutinize research projects, sowing turmoil.
