Small Mexico City Earthquakes Reveal Big Risks for Buildings

A recent swarm of small, shallow earthquakes in Mexico City has raised new concerns about how moderate earthquakes might impact the city buildings. Researchers found that even relatively weak earthquakes produced surprisingly strong ground shaking prompting them to explore potential damage in future scenarios. In a study published in the Bulletin of the Seismological Society of America Miguel Jaimes and Gerardo Suárez from Universidad Nacional Autónoma de México modeled the expected damage from moderate earthquakes in three key regions of the Mexico City basin. Their scenarios were based on past earthquakes including a 2023 event in La Magdalena Contreras the 2018 San Juan de Aragón earthquake and the 1995 Milpa Alta and 1985 Juchitepec earthquakes. Their findings highlight the criti...

5.3 Magnitude Earthquake Shakes Telangana: Residents Mistake Tremors for Monkey Mischief

Breaking News, Disasters

Mulugu, Telangana: Early Monday morning, residents of Mulugu in Telangana were startled by what they initially thought was the work of mischievous monkeys. However, as walls began to shake and utensils clattered, it became clear that the region was experiencing a 5.3 magnitude earthquake. The quake, one of the strongest recorded in the area in 55 years, caused tremors that rippled across parts of central and northern India. Residents Share Their Experiences Mangamma, an Auxiliary Nurse Midwife from SS Tadvai, recalled, “I was sorting things at home when the vessels and cot started shaking. At first, I blamed the monkeys, but when the walls trembled too, I froze in confusion. It lasted about a minute.” Similarly, A. Trishul, lying on his bed during the quake, mistook the monke...

Revolutionizing Seismology: Machine Learning in Earthquake Detection

Breaking News, Disasters

In 2017, Ross experienced a breakthrough that could reshape the field of seismology. Observing the prowess of machine learning programs in processing and categorizing vast sets of images with unmatched speed and accuracy, he wondered: could this technology be adapted to detect earthquakes? Ross and his team began their innovative journey by collecting seismic waveforms from across Southern California, using data previously identified by scientists as genuine earthquakes. They created templates—essentially, snapshots of each earthquake's unique seismic wave pattern. With these templates in hand, they developed an algorithm designed to comb through seismic records, searching for quakes that matched these specific patterns. However, the initial program had its limitations. It was a prec...
