Stop Seismic Testing off the Central Coast of California

VICTORY the California Coastal Commission voted unanimously to deny PG&E's request to conduct seismic testing along the Coast of California!

Pacific Gas & Electric (PG&E) is seeking to conduct seismic testing off the Central Coast of California at the Diablo Canyon Power Plant.  These tests require firing underwater air guns (each one producing an explosion measuring approximately 255 decibels), day and night, for days on end.

By PG&E’s own admission, these tests have the potential to harm or kill thousand marine mammals!  Moreover, these tests may also pose a significant risk to any surfers, swimmers or divers in the water.

According to researchers, including a scientist at the United States Geologic Survey (USGS), the data derived from this project is duplicative and may not answer key questions regarding plant safety.  PG&E has not made the case that these destructive tests are necessary to improve plant safety.

Please help us stop seismic testing off the Central Coast of California by attending the California Coastal Commission hearing on November 14th!

If you do not speak out now we will likely be unable to stop this project from taking place.  Not only will this project cause great harm to the Central Coast, it virtually guarantees a similar project to take place off San Onofre in the next few months!

What: California Coastal Commission hearing on proposed seismic testing.

Where: Santa Monica Civic Auditorium – East Wing 
1855 Main Street 
Santa Monica, CA 90401

When: November 14th, starting at 9am

Why: Help us keep our coast open to swimming, surfing and diving and protect thousands of marine mammals!
