Cowell’s Cove is a beach in Santa Cruz, California noted for good surfing. The Santa Cruz coastal area is in the form of a broad (5 km) short (1.5 km) bay, facing south
? On the west side of the beach is a long (1 km) raised peninsula with a steep rocky cliff edge. The top is about 5 m above the water level. Behind the peninsula, the ground rises in a neighborhood of twisty, one-lane streets to a level 15 m above sea level. The nearest stairway is about 100 m away. To the east, the beach is flat leading to a popular tourist boardwalk. Your car is parked behind the boardwalk about 200 m away. Behind this area a straight two-lane road goes through the downtown area for about 5 km before reaching Highway 101 and hilly country. ? The sea is calm and flat except for a regular line of clean surf breaks surf breaks about 1 m high along the peninsula. You feel a slight jolt. Some rocks tumble from the cliffs, and you can hear car horns honking at areas along the beachfront. After looking around for a few minutes, you notice that the edge of the water is receding quickly, and hear sirens from emergency vehicles in some directions. ? Assume that you are physically fit, and that your car is in good working order. What do you do? Explain your reasoning. What will be an ideal response?
