Final answer:
The risk of a volcanic explosion at Yucca Mountain is low.
Step-by-step explanation:
The risk of a volcanic explosion at Yucca Mountain is considered low. Yucca Mountain is located in Nevada, and while it is a volcanic region, the volcanic activity in this area is considered to be dormant. Dormant volcanoes have not erupted in the past 10,000 years, but they still have the potential to erupt in the future.
However, it is important to note that volcanic eruptions are difficult to predict, and monitoring and research are essential to keep track of any changes.
