Residents in parts of Fremont, California, reported hearing a loud noise on Monday night, according to posts on social media and local online forums. The cause of the sound has not been confirmed.
Several users on X and Reddit said they heard or felt a “boom” in and around Fremont, with some claiming it was audible in neighboring areas such as Union City, Hayward and Newark. To be sure, local authorities have not issued any statement on the reports so far. And these accounts could not be independently verified by HT.com.
Posts on the Reddit Fremont thread included residents asking whether others had heard a loud noise, with some describing minor vibrations in their homes. Others said they noticed a limited number of fire engines in the area, though it was unclear whether these were connected to the reported sound.
There were also unsubstantiated claims online suggesting an incident may have occurred near Northgate Park on Milton Street. However, other users who said they live nearby reported no visible activity, and suggested that any emergency vehicles had already left the area.
HT.com has contacted the Fremont Fire Department for clarification and will update this report as and when official information becomes available.
