5. [Note: this question has two (2) pages.] We started the semester talking about the explosive eruption at Hunga volcano and later we learned about the explosive eruption at Mt. Pinatubo (both VEI 5-6). We are going to compare the sizes of these eruptions, then think about the consequences of a similar size eruption in Mexico, a country with volcanoes capable of similar explosive eruptions. A. Below are satellite photographs of the ash plumes from the 1991 Mt. Pinatubo and the 2022 Hunga eruptions, both taken approximately one (1) hour after the eruption started. What is the diameter of each ash plume? How do they compare in size? 1997 Mt. Pinatubo 2022 Hunga B. Popocatepetl is a stratovolcano near Mexico City that has erupted explosively in the past. If Popocatepetl had an eruption the size of the 1991 Pinatubo event, using what you learned about the Pinatubo eruption in this course, which eities on the map below would have significant ashfall? How thick would the ash accumulation be in those cities? 200 km [Continued on next page!

D. Another volcanic hazard we learned about is a lahar. What is a lahar, and why is it dangerous? E. The map below shows previous paths of lahars coming from Popocatepetl. One of those paths leads towards the city of Puebla (population over 3 million, so about the size of Los Angeles). If lahars travel at approximately 35 km/hr (20 mph), how much warning time would people in Puebla have before it arrived? [Remember your units!! Mexico City Popocatepet! Volcano Puebla 10 km F. Mexico City is one of the largest cities in the world (population over 20 million!!). What systems should be in place and what precautions should people in Mexico City take to protect against volcanic hazards? As part of your answer, you should define the specific hazards in Mexico City.
