Around 10 buildings collapsed in Ramona, Dawson and the other areas surrounding downtown. | |||
Santa Cecilia was partly disconnected due to a truck that crashed into one of the stores, blocking the main road, and the bay bridge being in bad shape. Around 5 buildings collapsed in Santa Cecilia, but many of the beach houses were badly damaged and had to be rebuilt entirely. | |||
Los Llanos, Palma and Rio Pueblo werent hit as hard with in total only 7 houses collapsing, but with many being in bad shape. However Due to the emergency services focusing on the airport and downtown, looting was a big problem after the earthquake. | |||
Rockwell had a lot of unstable beach houses, even before the earthquake so 18 buildings collapsed, with many being in bad shape. A parking structure of the Tropicana Palms hotel collapsed, and a lot of roads were blocked by debris. | |||

The Glenview waterfront was blocked off from the rest of the city, due to the interstate collapsing onto every road into Glenview. The residents of the area came together and set up a first aid camp on the waterfront park, they also made a temporary living setup for residents with houses in bad shape, or without them. | The Glenview waterfront was blocked off from the rest of the city, due to the interstate collapsing onto every road into Glenview.

Ashfield central was flooded due to multiple sewerpipes bursting. Many residents evacuated the tall buildings and were brought to the ashfield waterfront by the Ashfield police. The police couldnt reach other areas due to flooding and collapsed infrastructure, so they helped rescue victims of collapsed buildings, and keep ashfield as safe as possible. | Ashfield central was flooded due to multiple sewerpipes bursting. Many residents evacuated the tall buildings and were brought to the ashfield waterfront by the Ashfield police. The police couldnt reach other areas due to flooding and collapsed infrastructure, so they helped rescue victims of collapsed buildings, and keep ashfield as safe as possible. They set up a large temporary living camp on the grass field in the park, and police evacuated people to get them away from the buildings in case there was another aftershock. | ||
Downtown was a mess, with collapsed infrastructure and heavily damaged buildings it was already very hard to navigate, but with all the toxic fumes and debris that came from the collapsed tower, it became even harder for the police to evacuate people to a save space. Everyone was forced to wear a mask so they wouldnt breath in as much of the toxic air. The citizens were evacuated to three spots in the city, the city hall, the downtown marina and the santa cecilia bay bridge. | |||
A large fire started in Chinatown, burning down atleast 5 buildings before it was put out by the residents of the area. | |||
Ramona, Dawson and other areas near downtown were neglected by emergency services and looters ran around the streets. The ground under one of the houses in Ramona collapsed onto the interstate nexto it. Blocking one of the only still nagivable interstates to downtown. While some streets in Ramona were flooding due to bursted sewer pipes, they still managed to set up a first aid camp on the parking lot of the ramona plaza mall, a large stripmall. Residents came together to help others out of collapsed buildings, and put out fires. | |||
Santa cecilia was partly disconnected so they couldnt get as much help from Downtown emergency services as other areas. Luckily many residents voluntarily made a first aid camp on the beach, and helped others get out of badly damaged buildings. | |||
Los Llanos, Palma and Rio Pueblo were all very badly hit by looters and fires raged in the areas due to emergency services focusing on the airport and downtown. A first aid camp was made near the convention center. | |||
Rockwell was a mess with many residents hurrying out of their houses onto the beach, with lots of rubble in and around the area. An emergency aid camp was set up by the palma police department to resident the victims of the earthquake. | |||
== The day after the earthquake. == | |||
A lot of infrastructure was either blocked, or collapsed so especially in and around downtown heavy gridlock was in effect, A lot of the main interstates were blocked off by emergency services, so people had to drive through city streets to get away. Santa Cecilia was one of the only places people could easily drive through, however with the mass of traffic going into the small side streets, Santa Cecilia ended up gridlocked aswell, so did Ramona, Dawson Los Llanos, Rio Pueblo, Ashfield, Glenview and Westwood. Many of these were pretty dangerous without power or police supervision. Emergency services started rescues all over the city and took over most of the makeshift first aid camps. Surrounding cities in california sent rescue operations to help with the damage, including LA, San Francisco, And multiple cities in the valley. | |||
With flooded, blocked or collapsed infrastucture, gridlocked traffic and rescue operations going on all over the city the last thing they would want was another aftershock to start. | |||
So at 3:59:19 p.m. PST the second aftershock, almost 12 hours after the first struck. An 6.8 aftershock that lasted for 10-20 seconds struck the city. | |||
