| EARTHQUAKE ECOLOGY During the “era of reclamation” from the mid 19th Century until the early 21st Century, increased human control over the Delta was deadly for the native fauna. Overfishing, development, pollution, water diversion, and the introduction of non-native catfish, bass, and American shad decimated indigenous fish populations. The loss of habitat and increased competition among the species had left the area’s animals struggling for survival. By the mid-1990s, winter salmon runs that had numbered in the millions during the early 19th Century were down to as few as 191. The Las Trampas earthquake devastated the human
landscape, but it offered a new possibility of life to many struggling
animals. When the former Delta turned into a large lake and marshlands,
fish, birds, amphibians and reptiles that had been all but extinct began
to reclaim their former territory. Aquatic life took over submerged buildings
and highways, which became like gigantic inland reefs. The tops of high
buildings, now dotting the region as tiny islands, became nesting areas
for migrating birds and new homes for turtles, frogs, and other water-going
animals.

ECOLOGIA DE TERREMOTOS El terremoto Las Trampas devastó el paisaje humano, pero ofreció nuevas posibilidades de vida a muchos de los animales que quedaban en la region. Cuando el Delta se convirtio en un lago grande y cienaga, los pez, los pájaros, los anfibios y los reptiles cuales habian casi desaparecido, comenzaron a reclamar su territorio anterior. La vida acuática reclamo los edificios y las carreteras sumergidas, cuales se convirtieron en arrecifes enormes. Los techos de edificios altos, ahora salpicando la region como islas pequeñas, se convirtieron en areas de nidos para pajaros migratorios y nuevos hogares para las tortugas, las ranas, y otros animales dependiente de agua. |
