He has had a prolonged and complicated postoperative course, including respiratory failure and delirium. The delirium workup included a urine culture, which was positive for Escherichia coli and treated with a 10-day course of trimethoprim-sulfamethoxazole. The antibiotic course finished 3 days ago. He is now extubated, mentally clear, and making slow but forward progress. You are called by the bedside RN to evaluate a new rash. There is a diffuse erythematous maculopapular rash over his upper anterior chest. His arms, stomach, back, and legs are unaffected. He reports a raw burning sensation over the affected area.

What tectonic setting is at this location? Tip: Recall which tectonic setting produces the volcano you chose in the previous question, then check the map to see if there are any additional clues (ie. if it is a rhyolitic composite volcano, you would expect it to be near the edge of a continent, indicating there is an ocean-continent convergent boundary)
