Mystery Booms Continue Daily Sonora, CA, Meanwhile South Bay Earthquake Swarm Continues Near Hollister, California
A mysterious booming noise in a small California town has residents baffled, and has sparked many conspiracy theories.
Every weekday, between 11 a.m. and 2 p.m., a thunderous noise rocks through Sonora, California, according to locals.
The cause of the mysterious booms remains a mystery, with local residents pointing to everything from mining operations to aliens.
Glen White, a local teacher and geologist who has researched the sound extensively, told local ABC affiliate KXTV-TV that he thinks the noise comes from bombs and grenades exploding.
White said he believes the explosions come from an Army depot outside of Hawthorne, Nevada, about a hundred miles away from Sonora. There, a private company disposes and dismantles old munitions, White said.
“They go through old munitions bombs, grenades, then they destroy them,” White explained, and has video footage to back up his claim.
Ken Thomas, a contracting officer for the Hawthorne Army Depot, told ABC News today that they do detonate munitions regularly at the depot when the munitions are past their shelf-life, but he is not convinced that it can be heard in Sonora.
“It doesn’t feel right that what we’re doing here would be heard 200 miles away when there’s a mountain range in between us,” Thomas said. “My office is 27 miles from where they detonate the old munitions, I only hear it here maybe one time a month, and just barely and it’s like ‘Was that a boom?'”
While White thinks he has solved the town’s mystery, he told KXTV-TV he remains open to hearing other people’s theories, as long as they are backed up by scientific research.
South Bay earthquake swarm continues near Hollister, California
An earthquake swarm is continuing to rattle the South Bay near Hollister. In the past four days, more than 39 tremors have hit the area on a section of the San Andreas system known as the Calaveras Fault. Between Sunday night and Monday afternoon, 39 quakes greater than 1.0 have occurred and 20 more than 2.0, seven over 3.0, one 4.1 and one 4.2, according to the U.S. Geological Survey.
The first struck Sunday night at 10:26 a.m., 12 miles southeast of Hollister, and had a preliminary magnitude of 3.3. Over 260 people reported the incident to the USGS. The largest quake recorded on Monday gave a gentle shake at 2:27 a.m., 12 miles northeast of Hollister, and had a preliminary magnitude of 3.8.
Several quakes shook the area on Tuesday, including a 4.2 trembler recorded 11 miles southeast of Hollister and 17 miles east of Salinas. Over 650 people reported feeling this quake. On Wednesday, tremors continued to gently shake the area, and the USGS recorded two 3.0 earthquakes. One hit 12 miles southeast of Hollister at 5:14 a.m. and another two miles southwest of San Juan Bautista and nine miles west of Hollister at 7:08 a.m.
No injuries or damage have been reported.
Earthquakes with a magnitude of 3.0 are common along this area of the fault, and swarms occur more rarely. A series of 4.0s and 4.6s hit in the early 1970s, and in 2001, the USGS recorded three earthquakes around 4.0.
“This part of the Calaveras Fault creeps and it continually deforms,” explains Ole Kaven, a research geophysicist with the USGS. “What that generally suggests is that strain doesn’t build up sufficiently to create very large earthquakes, though that possibility can’t be entirely excluded.”
