Seismologist Raises Alarm Over Escalating Earthquake Activity in Southern California
Notable Spike in Seismic Activity
Yesterday’s earthquake of 4.4 magnitude, which brought uneasiness across the vicinity of Los Angeles, signifies an escalating trend of increased seismic activity in Southern California. This trend is likely to sustain, states the region’s leading seismologist.
“This year has seen the occurrence of more earthquakes than any other year since 1988,” says Dr. Lucy Jones, a prominent geophysicist and research scientist. Starting from 1932 and onwards, Southern California experienced on average 10 to 12 earthquakes of 4.0 or higher magnitude annually. However, the similar average of the past two decades has been reported as only five such quakes each year. With the year far from over, the region has surprisingly registered 13 tremors measuring at or above 4.0 magnitude.
Historical Earthquake Pattern in the Region
A pattern has been observed where these complex natures of earthquakes have been mysteriously coming to life in this region. Dr. Jones goes on to say, “So, this year is proving to be an active one, resembling the activity we used to see in the past. It gives an impression that we should anticipate the continuation of this increased activity rate for a while.”
As per the U.S. Geological Survey, Monday’s 4.4-magnitude quake, with its epicenter in Los Angeles’ Highland Park neighborhood, happened along the Puente Hills thrust fault system. Although this did not result in any significant damage, it came less than a week after another seismic event, which was 5.2 on the Richter scale and occurred near Bakersfield. This quake as well caused widespread anxiety across Southern California.
A Series of Small Shakes Doesn’t Mean No Big Quake
Commonly, individuals believe a series of minor quakes lessen the chance of a major one hitting in the future; however, Dr. Jones clarifies that the relative number of large over small quakes is the constant feature of earthquakes. Therefore, if the number of 4.0 or above magnitude quakes increases, the probability of a severe quake hitting the area would also rise correspondingly, meaning more earthquakes can essentially mean – more earthquakes. While the exact timing of the anticipated “big one” remains unpredictable currently, Dr. Jones reassures the public that California is well-prepared and has strong plans in place for such a situation.
Preparation is Key
Dr. Jones emphasizes the fact that California’s built environment including its houses and other structures are primarily made not to collapse. She also emphasizes that being prepared does not only imply having supplies, but it also means being well-aware of what to do in such situations. “Simply having water isn’t enough, but having a plan discussed with family and friends about what should be done in such situations is probably more important than anything else,” says Dr. Jones.
This recent increase in seismic activity serves as a timely reminder for all residents of the region to remain constantly aware and prepared for possible future earthquakes. More measures in terms of public safety, improvements in infrastructure, and continuous monitoring of earthquake activity will help in mitigating the impacts of such natural disasters.
