southeast Missouri experienced another tremor on Saturday, marking the fourth earthquake recorded in the region over the past three days. This latest seismic event adds to a recent pattern of minor geological activity.

The United states Geological Survey reported a magnitude 2.0 earthquake occurred at 12:23 a.m. on July 12. The epicenter was located approximately 2.7 miles east of Risco, with the tremor originating at a depth of 14.3 kilometers.

As of now, no residents in the immediate vicinity have reported feeling the quake. Data from the USGS indicates that no one has yet submitted a report about experiencing this particular earthquake.

This weekend’s event follows a series of other small earthquakes in Missouri. A magnitude 2.4 quake was recorded in central Missouri on Thursday morning. Additionally, two more small tremors struck southeast missouri on thursday night.

What is the New Madrid Seismic Zone and why is it important to Missouri?

Recent Seismic Activity in the Midwest

A minor earthquake rattled parts of Missouri earlier today, July 12, 2025, prompting reports from residents across several counties.While no significant damage or injuries have been reported, the event serves as a reminder that earthquakes, though infrequent, do occur in the state.The United States geological Survey (USGS) confirmed the earthquake, initially reporting a magnitude of 3.6.Later revisions adjusted the magnitude to 3.4 on the Richter scale.

The epicenter was located approximately 8 miles northwest of Columbia, Missouri, at a depth of 5 kilometers (3.1 miles). Shaking was felt in Columbia, Jefferson City, and as far west as Kansas City, though reports indicate the intensity varied significantly depending on location and geological conditions. This event falls under the category of a microearthquake or minor tremor, generally not causing structural damage but often felt by people.

understanding Missouri’s Earthquake Risk

Missouri sits within the New Madrid seismic Zone (NMSZ), a highly active seismic region responsible for some of the largest earthquakes in U.S. history.

Historical Context: The NMSZ was the site of a series of powerful earthquakes in 1811-1812, estimated to have been between magnitudes 7.0 and 8.1. These events caused widespread damage and altered the course of the Mississippi River.

Geological Factors: The zone is caused by ancient faults reactivating due to stresses in the Earth’s crust. The underlying geology of the region, including layers of sediment and rock, can amplify seismic waves.

Frequency of Earthquakes: While large earthquakes are rare, smaller tremors occur frequently within the NMSZ. The USGS estimates that approximately 200 earthquakes are recorded in the zone each year, most of which are too small to be felt. Seismic monitoring is crucial for tracking these events.

What to Do During an Earthquake in Missouri

Knowing how to react during an earthquake can significantly reduce your risk of injury. here’s a breakdown of recommended safety procedures:

1. Drop, Cover, and Hold On: This is the universally recommended action. Drop to your hands and knees, cover your head and neck with your arms, and hold onto something sturdy.
2. If Indoors: Stay inside. Move away from windows,glass,and anything that could fall. If you are in bed, stay there and protect your head with a pillow.
3. If Outdoors: Move to a clear area away from buildings, trees, and power lines.
4. If in a vehicle: Pull over to a safe location and set the parking brake. Stay inside the vehicle until the shaking stops.
5. After the Shaking Stops: Check for injuries. Look for damage to utilities (gas,water,electricity). If you smell gas, evacuate instantly and report it to the authorities.

Earthquake Preparedness for missouri Residents

Proactive readiness is key to mitigating the impact of a potential earthquake. Consider these steps:

Emergency Kit: Assemble an emergency kit containing essential supplies like water, non-perishable food, a first-aid kit, a flashlight, a radio, and medications.

Home Safety: secure heavy objects that could fall during an earthquake. Consider earthquake straps for furniture and appliances.

Family Plan: Develop a family emergency plan,including a designated meeting place and communication strategy.

Insurance review: Review your homeowner’s or renter’s insurance policy to understand your coverage for earthquake damage. Earthquake insurance is often a separate policy.

Stay Informed: Monitor local news and weather reports for updates on seismic activity.The USGS website (https://www.usgs.gov/) provides real-time earthquake information.

Recent Seismic Events & Data Analysis (2024-2025)

Data from the USGS indicates a slight increase in minor earthquake activity within the NMSZ over the past year. While this doesn’t necessarily indicate an impending major earthquake, it highlights the ongoing seismic risk.

2024: 187 earthquakes recorded within the NMSZ, with the largest magnitude being 3.8.

2025 (Year-to-Date): 112 earthquakes recorded, including today’s 3.4 magnitude event.

Trend Analysis: Seismologists are continuously analyzing data to identify patterns and assess the potential for future earthquakes. Seismic hazard maps are regularly updated to reflect the latest research.
