Phreatic explosion in January 1994

On about 15 January 1994, Bolivar Miranda, a SERNAGEOMIN chemical engineer, observed a 5-km-high explosive column rising above Tinguiririca from a location 65 km W. A photograph taken by his son, Matías, showed a distinct white cauliflower-shaped column on a clear day. Based on the shape and growth of the column, this eruption was most likely phreatic.

Information Contacts: J. Naranjo, SERNAGEOMIN, Santiago.

Deformation during 2010 Feb 27 - 2010 Feb 27 [Subsidence; Observed by InSAR]

Start Date: 2010 Feb 27 Stop Date: 2010 Feb 27 Direction: Subsidence Method: InSAR
Magnitude: 12.000 cm Spatial Extent: 15.00 km Latitude: -35.000 Longitude: -70.000

Remarks: Short-lived subsidence triggered by the Mw 8.8 2010 Maule earthquake

Figure (see Caption)

Volcanic ground subsidence observed in interferogram stacks spanning the earthquake (with earthquake effects removed). We assume the ground displacement is of short duration compared to the interferogram time span, so we compute the stack by summing the interferograms and dividing by the number of measurements in the stack for each pixel.
