Task: Question Generation
Input (English): Passage: Hazards stemming from volcanic activity at Ubinas are mainly the fallout from explosive eruptions, lahars of different origins, large landslides that can generate debris flows and pyroclastic flows. Small explosive eruptions are the most likely occurrences at Ubinas, while large Plinian eruptions are considerably less likely. The area of the cone itself is the area most likely to be affected by volcanic phenomena, while pyroclastic flows and lahars are a danger for the valleys that drain Ubinas in southeastern direction and landslides are hazardous for an area of the southern flank. The town closest to the volcano is only 4 kilometres (2.5 mi) away from Ubinas. Large Plinian eruptions could have effects on the city of Arequipa.The Peruvian INGEMMET geological service monitors the seismic activity, any deformation of the mountain, and hot spring and gas composition at Ubinas. It regularly publishes a report on the activity of Ubinas. Hazard maps were created during the 2006 eruptive event to show the relative risk in various locations around the volcano, which is graded in a three-zone scheme with one high-risk, one intermediate-risk and one low-risk zone. A contingency map was created to show and explain the procedures to follow in case of various eruption scenarios. Both maps were widely disseminated after publication to aid in the response to future eruptions.
Output (English): What is the name of the thing that has three risk zones?
