Big Bear Lake (4.8 km NNE of epicenter) [Map] / Very weak shaking (MMI II) / single vertical bump / very short : Just after 3:00 pm on 3-13-2023. I was sitting up in bed reading news articles on my Android. Felt a quick and sudden jolt. Asked my adult daughter in next room, she felt it too. Live up in Big Bear Lake, CA and no wind currently. Earthquake felt small here, but sudden movement,a jolt then stopped. So uncertain if earthquake or not? I am born & raised in So Cal,been through earthquakes before. Felt like it. | 5 users found this interesting.
