Penn State researchers found Masaya's caldera sank then rose across six years of satellite radar, while its Santiago crater deflated throughout. The authors read that as two reservoirs behaving separately, something monitoring has to account for at a volcano within 21 km of 2 million people.

Crystals from three La Palma eruptions trace each one to a deep magma recharge days or weeks earlier
Crystals in lava from La Palma's 1712, 1971 and 2021 eruptions show hot mantle magma stirring a mush 18 to 25 km down days or weeks before each one. The authors say that record helps read future unrest at depths monitoring networks struggle to see, though it cannot date the next eruption.

Seventeen NISAR radar frames trace Krasheninnikov's lava as it overflows its crater
NISAR scientists turned 17 radar frames of Kamchatka's Krasheninnikov volcano into a time-lapse of lava filling and overflowing its crater. Two looks every 12 days are enough to follow a lava field that grows over months, though the satellite began imaging about five months into the eruption.

Two radars looking from opposite sides caught Erta Ale sinking during Hayli Gubbi's eruption
Wenbin Xu's team combined NISAR's left-looking radar with Sentinel-1's right-looking passes over Ethiopia's Afar Depression. The largest ground motion during November's Hayli Gubbi eruption sat next door, at Erta Ale.

A Yellowstone super-eruption scenario starts eight weeks out with a migrating earthquake swarm
A thought experiment published by The Conversation walks a Yellowstone super-eruption from the first earthquake swarm to a VEI 8 blast, and the timeline it lays out hands monitoring staff two months of ambiguous signals.

Modeling pins Ol Doinyo Lengai's 2024 bulge on a million cubic meters of new magma
D. Sarah Stamps's team attributes a short-lived swelling at Tanzania's Ol Doinyo Lengai to about 1 million cubic meters of magma roughly three kilometers down, a figure that comes out of numerical modeling of surface motion.
