What Happened
On June 13, 2025, a magnitude 2.9 earthquake was registered by the U.S. Geological Survey (USGS) near Dacono, Colorado, approximately three miles southwest of Denver. The earthquake occurred at around 6:18 a.m. local time and was reported to be relatively shallow, with its epicenter located about 5.09 miles beneath the surface. Residents across the Denver metro area reported feeling light shaking, particularly along Interstate 25 and in surrounding towns. As of the morning following the quake, no damage had been reported, and the USGS noted that this event was significant due to the rarity of earthquakes in the Denver area.
The earthquake was notable not only for its occurrence but also for the context in which it took place. The last recorded earthquake of magnitude 3 or higher in the Denver metro area was in 1981, when a magnitude 4.3 earthquake occurred in Northglenn. The USGS indicated that the shallow depth of the quake likely contributed to the widespread sensation of shaking felt by residents, as it occurred during a time when many people were awake and preparing for their day.
Key Details
- Magnitude: 2.9
- Location: Approximately 3 miles southwest of Dacono, Colorado, north of Denver
- Depth: 5.09 miles beneath the surface
- Time of Occurrence: 6:18 a.m. local time on June 13, 2025
- Reported Feelings: Light shaking reported throughout Denver and surrounding areas, with intensity varying from weak to moderate.
- Historical Context: Last significant earthquake in the Denver metro area was a magnitude 4.3 in 1981.
- Public Response: As of 7:29 a.m. on the day of the quake, 145 individuals had reported feeling the earthquake to the USGS.
Multiple Perspectives
The earthquake has elicited various responses from residents and experts. Some residents described the sensation as akin to a heavy door slamming, while others reported hearing loud booms during the shaking. This subjective experience highlights the varying perceptions of seismic activity among individuals.
Seismologists and geological experts have pointed out that while earthquakes are infrequent in Colorado compared to more seismically active states like California and Alaska, the state does have a history of seismic activity. According to the Colorado Geological Survey, there are five known faults in the state, three of which have generated earthquakes of magnitude 7.0 or greater. This context suggests that while the recent earthquake was minor, it serves as a reminder of the geological dynamics at play in the region.
Context & Background
Earthquakes in Colorado are generally less frequent and of lower magnitude than those in more active regions. The state has recorded over 700 earthquakes of magnitude 2.5 or higher since 1867, but the majority of these events are minor. The geological framework of Colorado includes several faults, but the overall seismic risk is considered lower than in states along the Pacific Ring of Fire.
The occurrence of the June 13 earthquake may prompt discussions about preparedness and awareness of seismic risks in the Denver area. Given that significant earthquakes have occurred in the past, including those of magnitude 7.0 or greater, local authorities and residents may need to consider their emergency response plans and building codes to mitigate potential risks.
What We Don’t Know Yet
As of now, there are several uncertainties surrounding the June 13 earthquake. While no damage has been reported, it is unclear whether any aftershocks will occur or if this event may be indicative of larger seismic activity in the future. The USGS continues to monitor the situation and encourages residents to report their experiences, which can help in assessing the earthquake’s impact.
Additionally, the long-term implications of this earthquake on local infrastructure and community preparedness remain to be seen. As more data is gathered, experts may provide further insights into the geological factors contributing to this event and the likelihood of future seismic activity in the Denver area.
