temblor

tem-BLOR

An earthquake. The word carries a different weight than its English equivalent — less clinical, more physical, closer to the body's experience of the ground shuddering beneath it. In California and the American Southwest, temblor is used interchangeably with "earthquake" in both journalism and conversation, a linguistic inheritance from the Spanish-speaking culture that named the landscape first.
Etymology
Spanish, from temblar, to tremble, from Latin tremulare. The word is a trembling — not the cause, not the mechanism, but the sensation. It entered American English through the seismically active borderlands where English and Spanish have always shared the ground.
