Earthquakes are a regular occurrence in many regions of the United States. Due to its location over active tectonic plates, the country experiences earthquakes of varying magnitudes throughout the year. According to reports from the U.S. Geological Survey (USGS), the areas with the highest frequency of seismic activity are California, Alaska, Hawaii, Nevada, Texas, New York, New Jersey, and the Washington D.C. Metropolitan area.
Seismic monitoring is ongoing and updated in real time through the USGS’s official platform. This system collects precise information about each event, including the exact time, the location of the epicenter, the depth, and the recorded magnitude. This data allows citizens, researchers, and authorities to assess seismic activity and strengthen prevention protocols.
Earthquake Report: Friday, February 20
The USGS publishes real-time reports of the latest earthquakes recorded in the United States today, Friday, February 20. This official record allows the public to track seismic activity and know precisely where and when these events occur.
In addition to real-time reports, the public can access the interactive Latest Earthquakes map and the ShakeAlert early warning system, which sends notifications seconds before a strong earthquake is felt. These technological tools are a fundamental part of the national strategy to reduce risks and foster a rapid and coordinated response.
What to Do Before, During, and After an Earthquake in the United States
Before an Earthquake
- Develop a family emergency plan and practice drills regularly.
- Identify safe zones in your home, school, or workplace.
- Prepare a kit with a flashlight, water, non-perishable food, a radio, medications, and important documents.
- Inspect the structure of your home and ensure that shelves and heavy objects are secured.
- Familiarize yourself with local evacuation routes and meeting points.
During an Earthquake
- Stay calm and avoid running or shouting.
- If indoors, drop, cover under a sturdy table, and hold on.
- Stay away from windows, lamps, and objects that could fall.
- If outdoors, move away from walls, poles, or electrical wires.
- Do not use elevators until authorities confirm This proves safe.
After an Earthquake
- Check your safety and the safety of those around you.
- Inspect your home for potential structural damage or gas leaks.
- Stay informed through official media and follow the instructions of the authorities.
- Avoid obstructing emergency routes.
- Offer assistance to those who need it, as long as you do not put your own safety at risk.
Frequently Asked Questions
What are the zones with the highest seismic risk?
The most exposed regions are California, Alaska, and the state of Washington, where important tectonic faults such as the San Andreas Fault and the Cascadia subduction zone converge.
How often do earthquakes occur in the United States?
Thousands of tremors are recorded each year, although most are of low magnitude and barely perceptible. Only a small fraction exceeds 5.0 magnitude.
What is the ShakeAlert system?
ShakeAlert is an early warning system that detects initial seismic waves and sends notifications to cell phones and emergency systems before the stronger tremors are felt.
Given the ongoing seismic activity in the United States, and the tools available for monitoring and early warning, how prepared do you feel for a potential earthquake in your region?
