LOS ANGELES – Thursday, July 30 was yet another day that Angelenos seemed to take in stride as the day started at about 4:30 a.m. with a 4.5 earthquake centered near Pacoima in the northern San Fernando Valley.
The U. S. Geological Survey later downgraded the quake to a 4.2 as a 3.3 magnitude aftershock rolled the area about 20 miles northwest of downtown Los Angeles about 10 minutes after the initial quake. A spokesperson for the USGS told the Los Angeles Blade that the early morning event hit at a depth of approximately 4.3 miles.
Caltech Staff Seismologist Dr. Jen Andrews told KABC7 that the Thursday morning temblor occurred near the area of the 6.7-magnitude San Fernando earthquake in 1971, and the 6.7-magnitude Northridge earthquake in 1994.
Andrews added that Caltech recorded 60 aftershocks today.
“It’s not possible for us to say today’s event is related to those (in 1971 and 1994), but it’s not surprising that we’re having seismicity in this area,” Andrews said. “We’ve got a number of fault signs nearby, including the Sierra Madre fault sign as well as the Mission Hills and Northridge Hills faults.”
Multiple Los Angeles media outlets reported that there were no immediate reports of serious damage or injuries due to the quake.
The quake seemingly set the tone for the rest of the day, as the Los Angeles County Public Health Department warned that temperatures around the region were expected.
“While it is very important that everyone take special care of themselves, it is equally important that we reach out and check on others, in particular those who are especially vulnerable to the harmful effects of high temperatures, including children, the elderly, and their pets,” Public Health’s Dr. Muntu Davis cautioned.
“High temperatures are not just an inconvenience, they can be dangerous and even deadly. But we can protect ourselves, our families, and our neighbors if we take steps to remain cool and hydrated. It is critically important to never leave children, elderly people, or pets unattended in homes with no air conditioning and particularly in vehicles, even if the windows are ‘cracked’ or open, as temperatures inside can quickly rise to life-threatening levels. If you have an elderly or infirm neighbor who is without air conditioning, check on them throughout the day,” he added.
A Heat Alert was issued as high temperatures have been forecast for the following areas:
Antelope Valley – through Monday, August 3
West San Fernando Valley –through Sunday, August 2
East San Fernando Valley –Friday, July 31, through Saturday, August 1
West San Gabriel Valley – Friday, July 31
East San Gabriel Valley – through Saturday, August 1
Santa Clarita Valley – through Saturday, August 1
LA Public Health has also announced that Cooling centers across the region will be open beginning Friday to provide the public relief from the heat.
Residents who do not have access to air conditioning are encouraged to take advantage of these free cooling centers. To find a location near you, visit this link https://ready.lacounty.gov/heat or call 211.

A brush fire that broke out Thursday afternoon in the Hollywood Hills on both sides of Laurel Canyon Drive was fully contained by early evening according to a spokesperson for the Los Angeles Fire Department. Firefighting crews were also working to contain a brush fire, dubbed the Dam Fire, that sparked in the Angeles National Forest Thursday afternoon near the Morris Dam in Azusa.
Adding to an already strife-filled day, the LA County Public Health identified the first two cases of human West Nile virus (WNV) infection in Los Angeles County for the 2020 season. According to a spokesperson for Public Health, an older adult with no underlying illness was hospitalized with neuroinvasive disease in early July and is recovering. The second case was detected in late July in a healthy blood donor. (The positive blood units were discarded.) Both are residents of the San Fernando Valley region
“West Nile virus continues to be a serious health threat to residents in Los Angeles County. We encourage residents to cover, clean, or get rid of items that can hold water and breed mosquitoes both inside and outside your home. This is important now more than ever as we spend the majority of our time at home,” said Public Health’s Dr. Davis.
Mosquito season in Los Angeles County starts in June and ends in November.
