Microsismos Shake Azcapotzalco: What You Need to Know
A pair of microsisms shook the Azcapotzalco district on the night of November 18. Authorities started inspecting buildings in the area following the seismic events.
The first microsism occurred at 21:22:03, registering a magnitude of 1.8 and a depth of one kilometer. The second microsism took place shortly afterward at 21:22:49, with a stronger magnitude of 2.2. Experts indicated these may not be aftershocks, as the coordinates of the two events differ.
Currently, the exact locations of the microsisms in Azcapotzalco are unknown. However, authorities are already checking buildings in the district. The Secretariat of Integral Risk Management and Civil Protection of Mexico City activated protocols to ensure public safety, although no damage has been reported.
The Azcapotzalco district mentioned that initial inspections show no signs of damage. Residents noted the tremors felt minor or unnoticeable.
What are the potential impacts of microsisms on everyday life in urban areas like Azcapotzalco?
Interview with Dr. Elena Torres, Seismologist, on Azcapotzalco Microsisms
News Directory 3: Thank you for joining us, Dr. Torres. On the night of November 18, two microsisms struck the Azcapotzalco district. Can you explain what defines a microsism?
Dr. Elena Torres: Thank you for having me. A microsism is essentially a very minor seismic event, typically ranging from magnitude 1.0 to 3.0. These tremors generally go unnoticed by the public due to their low intensity. The recent events in Azcapotzalco, registering magnitudes of 1.8 and 2.2, certainly fit this category.
News Directory 3: The authorities noted that these were not aftershocks. Can you elaborate on that point?
Dr. Elena Torres: Yes, the distinction is important. Aftershocks are smaller seismic events that follow a larger quake, typically occurring near the original epicenter. In this case, since the coordinates of the two microsisms differed, it suggests they were independent events rather than aftershocks of a larger earthquake.
News Directory 3: The seismic alert system did not activate for these events. Why is that?
Dr. Elena Torres: The C5 monitoring system in Mexico City is designed to sound alarms based on the potential for significant danger to residents. Since the magnitudes of these microsisms were too low to pose a risk, the alerts did not trigger. The system focuses on providing warnings for larger events where there is adequate time for citizens to evacuate.
News Directory 3: Are there any safety concerns for the residents following these microsisms?
Dr. Elena Torres: While the seismic events were too minor to cause any structural damage according to initial inspections, it’s always prudent for residents to stay informed and be prepared. The rapid inspections conducted by authorities in Azcapotzalco illustrate a responsible approach to public safety and ensure that buildings remain secure.
News Directory 3: Just before the microsisms, an explosion occurred nearby. Could there be any connection between the two events?
Dr. Elena Torres: It’s an interesting coincidence, but seismologically, explosions and microsisms typically result from different processes. Explosions create pressure waves that do not correlate with tectonic movements that cause earthquakes. However, we should await further investigation results to see if any underlying issues may link them, especially regarding public safety.
News Directory 3: Thank you, Dr. Torres, for your insights on these seismic events and their implications.
Dr. Elena Torres: You’re welcome! It’s crucial to keep the public informed and aware of these occurrences, and I’m glad to contribute.
Concern arose about why the seismic alert did not sound. The C5 of Mexico City explained that alarms do not trigger for microsisms within the capital due to their low intensity. Alerts activate to warn citizens in situations where they can evacuate safely. Because the strength of tremors is low, there is often no time to react during such events.
Before the microsisms, an explosion was reported in the San Pedro Xalpa neighborhood. Firefighters responded to the incident, and updates on any potential injuries are expected soon. The explosion reportedly took place at the intersection of Abraham Sánchez and José Gardel streets.
