The Earth is constantly moving, and sometimes it sends us warnings through unpredictable tremors. With the increasing frequency of earthquakes globally, even areas previously considered seismically safe are detecting unusual crustal activity. In particular, a magnitude 4.8 earthquake near New York City in April 2024 surprised many residents, and a magnitude 3.0 earthquake shook the New York-New Jersey area in August 2025, making the possibility of earthquakes in New York no longer a distant concern. In light of these realities, New Yorkers need to accurately recognize the risks of earthquakes and adopt a wise stance of preparedness for any eventuality.
New York City is not located on major active fault lines like California's San Andreas Fault. However, there are old and deep-seated faults beneath the surface of New York that can cause earthquakes. According to the U.S. Geological Survey (USGS), the likelihood of a major earthquake in New York City is considered moderate, but given the extremely high population density and complex urban environment, the risk cannot be underestimated. From 1700 to 1986, over 400 earthquakes of magnitude 2.0 or greater were recorded in New York State, and the magnitude 4.8 earthquake in April 2024 was the strongest earthquake near New York City since 1884. These historical records and recent seismic activities clearly show that New York City is a region where earthquake preparedness cannot be neglected.
New York City's unique architectural landscape can exacerbate damage during an earthquake. The complex interdependence of numerous high-rise buildings and aging infrastructure systems could lead to catastrophic consequences in the event of strong shaking. The high proportion of buildings constructed before seismic design provisions were adopted into the city's building code in 1995 raises concerns about their vulnerability. While tall buildings themselves may be less susceptible to certain types of earthquake damage, low-frequency vibrations from distant, large earthquakes can still affect them. Furthermore, ground shaking caused by earthquakes can lead not only to building damage but also to utility disruptions, fires, landslides, and soil liquefaction, threatening public safety. Therefore, customized earthquake preparedness strategies that consider New York City's specific characteristics are essential.
Since earthquakes strike without warning, calm and immediate response at the moment of occurrence is crucial for survival. The most important principle is to 'Drop, Cover, and Hold On.' If you are indoors, get under a sturdy table and hold onto its legs to protect yourself. Once the shaking stops, turn off gas and electricity, open doors to ensure an exit, and evacuate using the stairs. Never use elevators. If you are outside, move away from buildings, walls, utility poles, and power lines to an open area and protect your head. If you are driving, pull over to a safe location, stay in your vehicle, turn on your hazard lights, and keep the road clear for emergency vehicles. When evacuating, be sure to wear sturdy shoes to protect against broken glass.
Preparing before an earthquake is the most effective way to minimize damage. First, ensure safety within your home. Secure objects that could fall or tip over, such as furniture and televisions, by anchoring them to walls, and store fragile items in lower, more stable locations. It is important to create a family emergency plan that outlines each member's role, evacuation sites, and emergency contact information in the event of an earthquake. Additionally, prepare an emergency supply kit to enable self-sufficiency for at least 3 to 15 days. This should include water, non-perishable food (canned goods, energy bars, etc., requiring no cooking), first-aid supplies, a flashlight, a radio, a whistle, blankets, and extra clothing. Store these supplies in an easily portable backpack and regularly check and replace items with expiring dates. More detailed preparedness information can be found on the NYC Emergency Management website.
Even after the shaking stops, the danger is not completely over. Be aware of potential aftershocks and remain vigilant. After returning home, thoroughly check gas, electricity, and water systems. If you smell gas or if a carbon monoxide detector sounds, immediately open windows, evacuate, and call 911. Do not re-enter your home until its safety has been officially confirmed. If water pipes are damaged, shut off the main valve. If there is a risk of electrical shock, turn off power at the meter box. It is also important to check the sewer lines before using the bathroom in case of damage. Do not be misled by rumors or false information; act according to reliable sources such as radio broadcasts or official announcements. If there are injured individuals, provide first aid and seek professional help if necessary.
New York City, unlike in the past, is no longer completely free from the risk of earthquakes. Recent seismic activity serves as a stark reminder of the importance of earthquake preparedness. Recognizing that earthquakes can occur anytime and anywhere, it is paramount for individuals, families, and communities to develop thorough preparedness plans together. Small efforts such as preparing emergency supplies, creating a family emergency plan, and familiarizing oneself with earthquake action procedures can collectively become a powerful force in protecting precious lives during a crisis. We urge you to actively participate in making New York safer by regularly checking information provided by the U.S. Geological Survey (USGS) and NYC Emergency Management. Disasters cannot be prevented, but preparedness is possible.
Q1: Are earthquakes frequent in New York City?
A1: While New York City is not located on major fault lines like California, leading to a lower frequency of major earthquakes, it is an area where earthquakes can occur. Recent seismic activity, including a magnitude 4.8 earthquake in April 2024 and a magnitude 3.0 earthquake in August 2025, has been detected.
Q2: Are New York City's high-rise buildings safe during an earthquake?
A2: Buildings constructed after 1995 incorporate seismic designs, but older buildings may be vulnerable. While tall buildings can withstand certain types of seismic forces, they can be affected by low-frequency vibrations from distant earthquakes.
Q3: What is the first thing to do during an earthquake?
A3: Indoors, take a 'Drop, Cover, and Hold On' position by getting under a sturdy table and holding onto its legs for protection. Once the shaking stops, shut off gas and electricity, then evacuate safely using the stairs.
Q4: What should be included in an emergency supply kit?
A4: Prepare supplies for at least 3 days, including water, non-perishable food, first-aid items, a flashlight, a radio, extra clothing, blankets, a whistle, and sturdy shoes. Store these in an easily portable backpack.
