Airport Cellphone Lot |
|||||
|
N32 43.788' W117 11.337' This site is easy to get to and can accommodate a large amount of people. Driving I-5 South, exit at Sassafras and turn right on Laurel. Turn right on Harbor Drive. Turn right into an empty cell phone parking lot, just South of the Airport terminal, and park. At this site there are stress fractures running from North to South. This is in the same direction in which the fault travels. A dip in the asphalt runs with the fault and looks like it is for drainage, but there is no drain hole. This could be a possible sag-line(?). |

| Tidelands Park Scarpeage |
N32 4.154' W117 9.841' This site is easy to get to and can accommodate a large amount of people. From the I-5, merge onto CA-75 North, over the Coronado Bridge. Once you get off the bridge, take the first right at Glorieta Blvd. Park on the street next to the park. Walk in a Southeast direction (towards the water). About 30 meters before the water is a ridge that could be scarp. This park might be considered to be under the Allquist Priolo laws. |

| Coronado Yacht Club Scarp |
N32 40.945' W117 10.495' This site is easy to get to and can accommodate a large amount of people. From the I-5, merge onto CA-75 North, over Coronado Bridge. Turn slight right onto Pamona Ave. (CA 282 W). Turn left onto A Ave. Turn left onto 10th. 10th becomes Pamona Ave. Turn left onto Strand Way. End at 1631 Strand Way (Coronado Yacht Club) and park on the street. Across (North) from your vehicle is possible scarp. The scarp is diagonal, from lower right to upper left. The fault goes under the yacht club, but there are no visible signs of seismic shift. If the main gate to the club is open feel free to look around. Once you enter the club, walk North towards the water and docks. The fault travels from the Southeast (by the golf course) to the West (under the Chart House restaurant). |

| Coronado Ferry Landing Scarp |
N32 41.996' W117 10.334' This site is easy to get to and can accommodate a large amount of people. From the I-5, merge onto CA-75 North, over the Coronado Bridge. Turn a slight right onto Pomona Ave. (CA 282 W) and continue. Turn right onto Orange Ave and park at the meters just after the intersection with 1st. Walk East (toward San Diego harbor), past the ticket booth from the intersection of 1st and Orange. Turn left (North) on the cement walk-way past the fenced swimming pool for about 20 meters. On the bayside of the walk-way is the possible scarp. From this point, the fault line travels under the fenced swimming pool, towards the street intersection. Allquist Priolo could be a possible reason why there is a pool and a grass park, and not more high-price condominiums. |
