Ubinas is a stratovolcano in the Moquegua Region of southern Peru, 60
kilometres (37 mi) east of the city of Arequipa. Part of the Central
Volcanic Zone of the Andes, it rises 5,672 metres (18,609 ft) above sea
level. Its summit is cut by a caldera 1.4 kilometres (0.87 mi) wide and
150 metres (490 ft) deep, which itself contains a smaller crater. Below
the summit, Ubinas is a steep cone with a prominent notch on the
southern side. The most active volcano in Peru, it has a history of
small- to moderate-sized explosive eruptions and persistent degassing
and ash emissions. An eruption in 1667, its largest since prehistoric
times, produced scoria falls and pyroclastic flows. In 2006 and 2007
eruption columns led to ash fall in the region, resulting in health
issues and evacuations. During the most recent activity, from 2013 to
2019, a lava flow formed inside the crater, and as ash fell, surrounding
towns had to be evacuated.

Wikiquote quote of the day:
We are going to die, and that makes us the lucky ones. Most
people are never going to die because they are never going to be born.
The potential people who could have been here in my place but who will
in fact never see the light of day outnumber the sand grains of Arabia.
Certainly those unborn ghosts include greater poets than Keats,
scientists greater than Newton. We know this because the set of possible
people allowed by our DNA so massively outnumbers the set of actual
people. In the teeth of these stupefying odds it is you and I, in our
ordinariness, that are here. … what I see as I write is that I am
lucky to be alive and so are you.
