Answer:
b. it is probably about to erupt
Explanation:
An earthquake can cause shock between underground tectonic plates, volcano eruption or gas displacement inside planet Earth (rarer situation). In an earthquake there are fault openings on the earth's surface and landslides.
Tremors caused by volcanism may be strong, but are located in areas near volcanoes. They occur due to some rupture or internal eruption of the magma or gases trapped under high pressure. Its effects are not usually felt over long distances.
