Transcript text: What was the 1986 earthquake in California, along the San Andreas Fault, an example of?
Solution
The answer is the third one: a transform fault earthquake.
Explanation for each option:
A tsunami: A tsunami is a series of ocean waves caused by large underwater disturbances, such as earthquakes under the sea, volcanic eruptions, or landslides. The 1986 earthquake in California was not associated with any significant oceanic activity that would generate a tsunami.
A volcanic eruption: A volcanic eruption involves the expulsion of magma, ash, and gases from a volcano. The San Andreas Fault is not associated with volcanic activity; it is a tectonic boundary between the Pacific Plate and the North American Plate, where earthquakes occur due to the movement of these plates.
A transform fault earthquake: The San Andreas Fault is a classic example of a transform fault, where two tectonic plates slide past each other horizontally. The 1986 earthquake in California was caused by the movement along this fault, making it a transform fault earthquake.
In summary, the 1986 earthquake along the San Andreas Fault was an example of a transform fault earthquake.
