Earthquakes
Some 80 percent of all the planet's earthquakes occur along the rim of the Pacific Ocean, called the "Ring of Fire" because of the preponderance of volcanic activity there. Most earthquakes occur at fault zones, where tectonic plates – giant rock slabs that make up the Earth's upper layer – collide or slide against each other. These impacts are usually gradual and unnoticeable on the surface; however, immense stress can build up between plates. When this stress is released quickly, it sends massive vibrations, called seismic waves, often hundreds of miles through the rock and up to the surface.

De acordo com o texto,
A
maremotos ocorrem quando a energia acumulada entre placas tectônicas é liberada de modo abrupto, vindo, então, rapidamente à superfície.
B
terremotos podem ser imperceptíveis na superfície, ainda que tenha havido, de fato, colisão ou deslizamento de placas tectônicas.
C
maremotos, também denominados ondas sísmicas, ocorrem quando placas tectônicas colidem ou deslizam.
D
terremotos são mais frequentes na zona costeira do Oceano Pacífico devido à baixa incidência de atividades vulcânicas na região.

No trecho traduzido abaixo, inferimos que a alternativa B está correta.
"Estes impactos são normalmente graduais e imperceptíveis sobre a superfície; no entanto, o imenso estresse pode acumular-se entre as placas."
"Estes impactos são normalmente graduais e imperceptíveis sobre a superfície; no entanto, o imenso estresse pode acumular-se entre as placas."
