extrusive igneous rock
An andesite rock. it came out of the volcanic eruption of Mt. St. Helens...
It is currently not known when Popocatepetl will erupt again. It's most recent eruption was on July 4th 2013. It is generally very hard to know when a volcano will erupt though scientists are finding ways to know when to expect one.

What you would expect after an explosive eruption is darkened skies. You should also expect warmer temperatures.

Dormant volcano
A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from below the surface. So expect explosions and a lot of noise.
Sheild volcanoes generally erupt "quietly."
You would expect to find lava solidifying into basalt on the flanks of a volcano, most likely a shield volcano.
Complex Eruption???
