- •
2014 unrest at Chiles–Cerro Negro culminated in Mw 5.6 earthquake.
- •
Slip was shallow and consistent with El Angel fault zone.
- •
Earthquake was preceded, and potentially triggered, by mid-crustal pressurisation.
- •
The Mw 5.6 earthquake coincided with cessation of uplift and start of fall in seismicity.
- •
Earthquakes during volcanic unrest may inhibit the driving magmatic process.
