SAN DIEGO (KGTV) - The Julian area was shaken by a preliminary 4.2-magnitude earthquake late Wednesday.
The earthquake struck at about 4:33 p.m. and had a depth of about 10.0 k.m. A 3.0-magnitude aftershock - with a depth of about 11.6 k.m. - appeared to hit around the same area five minutes afterward.
Just before 8 p.m. Wednesday night, a 3.8 magnitude earthquake struck near Julian following a series of earthquakes and aftershocks earlier in the day. The earthquake registered at a depth of about 11.4 k.m.
San Diego Sheriff's said there were no initial reports of damages. SDG&E also said there were no initial reports of damage to gas or power lines.
North County Transit District (NCTD) trains were not allowed through the Del Mar Bluffs, located between Solana Beach Station and Sorrento Valley Station, immediately following the earthquake.
NCTD said Del Mar Bluffs will be closed until a track inspector can clear the route for safety. A BREEZE and MTS bus bridge was deployed to for service between Solana Beach Station and Sorrento Valley Stations.

"We certainly did feel quite a bit. Everything rattled and shook," said one employee at the Julian Gold Rush Hotel. She did say the hotel was not damaged in anyway and guests were doing fine.
An employee of Mom's Pie's in Julian reported a strong 'boom' instead of a roll.
"It was just real quick. Hit hard, rattled the windows ... We only had one jar break," an employee at Julian Cider Mill told 10News.
Residents across the North County and as far away as Chula Vista reported feeling the quake.
At least one San Diego Fire-Rescue team was seen rolling out after the quake to check for damage, according to 10News' Breaking News Tracker.
