Answer to Question 1

Convergent plate boundaries line the Pacific basin, since the Pacific is shrinking and the Atlantic is
growing due to plate tectonics motions. As plates subduct, they create earthquakes along their distance.
The Pacific basin also has some transform faults along it, including the San Andreas in California.



Answer to Question 2

Shallow-focus earthquakes have focal depths of less than 70 km; intermediate-focus earthquakes have
focal depths between 70 and 300 km; and deep-focus earthquakes have focal depths of more than 300
km. Divergent and transform plate boundaries produce only shallow-focus quakes, and all
intermediate- and deep-focus quakes occur along convergent boundaries

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.
