| 49. 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.
