Capulin Volcano, New Mexico by Vaughn Kerr

The Capulin Volcano was formed in the period of the Raton-Clayton Volcanic field, where the cone rose to over a thousand feet about the plain, which was aver 8000 feet about sea level. It is in located in New Mexico, the lava flowed from a single vent that was created from small fragments that was flung into the air, it solidified as cinders around the vent. This formed the oval cone that is there today.

What evidence do you see regarding the nature of past eruptions?

Evidence of the other episodes of activity can be seen in nearly 100 nearby volcanic peaks and lava capped mesas. There Is a series of the extinct volcanic peaks such as the Sierra Grande and the Johnson Mesa that is west of Capulin.

Was it explosive or quiescent? Why?

It is stated that it was a blast that created the Capulin, which form the conical mountain that cover the vent were the eruption occurred. It is said that the cinder was ejected during a successive eruption and fell back upon the vent. It also indicated that Capulin was an ear-shattering explosion.

What kinds of hazards would be associated with this particular volcano?

The hazards that was document was wildfires and wildlife that would have inhabited the land at the time of the eruption. In most recent documentation it speaks of wildfire and control burn to help the natural fire cycle.

Will it be likely to erupt again?

It does not seem that it would erupt in the future as the lava has seemingly move away from the Capulin as the many other approximately 100 additional peaks that were created nearby, indicate in my view the movement of the lava keep moving further away.

Note details of particular interest to you.

Volcanic fields stretch across New Mexico, yet their cause is not completely understood. Most volcanic activity in the world occurs at plate boundaries below the earth's surface, along the Pacific Ring (NPS, 2015).
