Question
hello can you please tell me how does this work? thanks
You are a volcanologist sent out to investigate Mt. Calvin volcano in Northern California; there have been recent small earthquakes and positive elevation changes near the summit of this volcano. While you were on location, the volcano erupted, spewing out an ash cloud with a column that extended upwards to 13 km. Your gas spectrometer measured total SO2 and CO2 concentration of about 24,000,000 m3, while your geologist colleagues measured pyroclastic and lava volumes of 20,000,000 m3 and 16,000,000 m3, respectively (for a total magma volume of 60,000,000 m3).
Based on your observations and utilizing the table above, classify the type of volcanic eruption. ________________________
The description of this eruption would be ____________________
The VEI for this eruption would be a category ______
What would be the recurrence interval for this type of eruption (e.g., how often)?__________
