Volcano Watch: It’s all about perspective; how to interpret an interferogram

Volcanologists use interferograms to detect unrest by observing how the surface of a volcano is deforming in response to migrating magma beneath the ground. But while interferograms can be beautiful and informative, they are also difficult to interpret.

Volcano Watch: Potential long-term outcomes of recent intrusions in Kīlauea East Rift Zone

While scenarios such as a new pit crater forming in the Chain of Craters or large seaward movement of the volcano’s south flank are less likely, current conditions provide an excellent opportunity to better understand what can happen in the long run.

Seismicity still spiked in Kīlauea’s upper East Rift, but slightly lower than previous day

The unrest could represent another pulse of magma being supplied to the upper East Rift Zone following the intrusive event July 22-25 near Pauahi Crater.

Kīlauea alert level remains elevated; magma movement means ‘possibility’ of eruption

Based on past historical activity, this event is much more likely to continue as an intrusion, but there is still a possibility of it ending in an eruption.

Signs of unrest in summit area of Big Island’s Kīlauea volcano continue, but ground deformation has leveled off

Seismicity beneath the summit region, which began Oct. 4, also decreased with the change in deformation early Saturday morning and remained low as of about 9 a.m. Saturday.
