After looking into the past of this supervoocano located in the Chilean Andes, Volcano Discovery posted an interesting article that suggests a large eruption could occur there in the near future.

The large 23.5 by 16.5 km caldera has been having an uplift rate of 5cm per year on average, amongst the highest ever observed in a volcano that isnt actively erupting. The supervolcano has been know to produce large eruptions 1 and 1.5 million years ago. Between 2006 and 2007, an uplift of 18cm was observed, and from 2007-2011, the volcano had an uplift of about a meter. In 2012, an uplift if 28cm was recorded. So far this year, an uplift of 25cm has been observed. This clearly shows that magma us rising from below ground, and is currently estimated to be at 5km depth.

Back in July, it was reported that 2 million m³ of new magma supplies were entering the magma chamber annually, far more than is needed to fuel even a moderate eruption. Since 2013, there have also been seismic swarms st the volcano, indicating that the magma is currently on the rise. 0.044 km³ of this enters the lava tubes directly beneath the field annually, with the largest earthquakes being up to 5.5 within the calderas. As of July, the average number of earthquakes per month is 4.

The volcano has had several violent eruptions, including at least 1 if VEI8 that occurred around a million years ago, and several VEI 6 and 7 eruptions. The latest eruption was 2000 years, and has been recorded as being a VEI6. Considering that the recurrance interval is 1000 years, suggesting another eruption in the near future is highly likely as a result.
