LongBeach is the 34th-largest city in the nation, 5th in California and 2nd in Los Angeles County (after Los Angeles).
The LongBeachearthquake of 1933 was a magnitude 6.3 earthquake that caused significant damage to the city and surrounding areas.
LongBeach once had a sizable Japanese-American population mostly working in the fish canneries on Terminal Island and small truck farms in the area, but the Japanese and Japanese Americans were removed for internment in 1942, and most did not return after their release from the camps.
Along the shore between LongBeach and Newport Beach, the settling or lateral movement of road fills across marshy land caused much damage to the concrete highway surfaces and to approaches to highway bridges.
At LongBeach, buildings collapsed, houses were pushed from foundations, walls were knocked down, and tanks and chimneys fell through roofs.
The earthquake was felt almost everywhere in the 10 southern counties of California and at some points farther to the northwest and north in the Coast Range, the San Joaquin Valley, the Sierra Nevada, and the Owens Valley.
