4.8-Magnitude Earthquake Shakes Poly Prep JORDAN MILLAR EDITOR-IN-CHIEF

While within the New York City metropolitan area and across tremors were felt for more than 30 seconds and there were areas such as Philadelphia, Maryland, and Boston. New Yorkers and Poly students in particular, who typically do not experience significant seismic events or activity, raised questions and concerns. “I thought it was Middle Schoolers running around upstairs,” said senior Ava Rosario. “I was in string ensemble on the second floor practicing for the concert. We thought it was middle schoolers running in the hallway so we kept playing. Afterwards, our teacher told us it was an earthquake and we were very surprised,” said senior Jasmine Grant-Phillips. The earthquake did have a preliminary magnitude of 4.0 and was located near Gladstone, N.J., according to the U.S. Geological Survey (USGS), an agency of the United States government whose work spans the disciplines of biology, geography, geology, and hydrology. Seismologists refer to the largest earthquake event in an area as a mainshock, which was recorded at 4.8 magnitude. Head of Operations Matt Stelluto and Director of Security Sal Bonaventura sent out an email to families and students notifying them of the magnitude 4.8 earthquake in Tewksbury, NJ that was subsequently felt throughout the tri-state area. “Please know that our students are safe. At this time there is no need to evacuate buildings. If there is an emergency, we will communicate with families by text and email,” the email read, assuring the community that School Operations and Safety and Security had been monitoring the situation closely throughout the remainder of the day.VIA U.S. GEOLOGICAL SURVEY According to the New York Times, “The U.S.G.S. has logged 188 earthquakes with a magnitude of 2.5 or no immediate reports of injuries or damage, the earthgreater within a 250-mile radius of New York City since quake did in fact trigger “numerous delays and tempo1957.

es of the plates (known as plate boundaries) can get stuck while the rest of the plate keeps moving. “Finally, when the plate has moved far enough, the edges unstick on one of the faults and there is an earthquake,” the USGS notes. The earthquake that occurred across the East Coast on April 5, according to the USGS, occurred as a result of “oblique reverse and strike-slip faulting at shallow depths in the crust” ; though the earthquake did not occur near a plate boundary, intraplate earthquakes (which occur in the interior of a tectonic plate), are possible. “While this earthquake is relatively small globally, earthquakes of this magnitude are commonly widely felt in the eastern United States because of efficient seismic wave propagation in the region,” states the USGS. The April 5 earthquake did occur in a region where faults have been previously identified and may be reactivated at any time, and its epicenter was near Whitehouse Station, N.J., about 40 miles west of New York City. The depth of the bedrock rupture was estimated to be at 2.9 miles. Despite not presenting significant damage, the earthquake did impact some air and train travel according to CNN. “Buildings are also older in the Northeast and may not be designed to the latest earthquake code”, as stated by the USGS. “This is particularly a concern for shorter buildings like houses. Earthquakes tend to shake in a faster backand-forth motion in the East compared to the West, which puts smaller buildings more at risk for damage, the USGS noted. Aftershocks of the earthquake and physical effects in East Coast residents were also documented by the USGS. In addition to the physical tremors, according to the New York Times, “People can experience anxiety, sleep problems and other health issues in the hours and days after a quake.”

Chasing Shadows: Poly Experiences Solar Eclipse ELLA SCHOENBURG CONTRIBUTING WRITER

T

he April 2024 solar eclipse was the first total eclipse visible from the United States since August 2017. Poly students were able to take time out of class to view the eclipse after listening to a presentation in the Chapel by Physics Teacher Joseph Fallica about the importance and significance of the solar eclipse. On average, a total solar eclipse occurs every few years, visibility varying depending on the viewer’s location. A solar eclipse occurs when the moon blocks the sun from the Earth’s view, causing it to go dark for a few minutes. But, in order for a total eclipse to happen, there are many factors that come into play. There are two planes that need to align for a total eclipse: the plane on which the Earth orbits the sun and the plane on which the moon orbits the Earth. On the Earth-moon plane, which is slightly inclined compared to the Earth-sun plane, there are two points opposite each other where the planes intersect, called nodes. During a solar eclipse, the moon must be at one of the two nodes. When the moon is aligned with one of the two nodes and in front of the sun, the sun will cast a shadow onto Earth, allowing viewers to see what is known to be the solar eclipse. There are two types of eclipses possible at that point — total, which is what Poly students saw

on April 8, and annular, which last occurred on October 13, 2023, though it was not visible from New York. The difference between the two is how close the moon is to the Earth. During the annular eclipse, the moon is at its furthest point from the Earth, causing the sun to not be fully covered, while during a total eclipse, the moon is at its closest point to Earth, fully covering the sun. When asked about his personal experience and opinions on the eclipse, Fallica said that, although the eclipse was exactly as he expected, he wishes to have had “better emphasized what 90 percent coverage would look like to the group prior to going outside.” Fallica stated that he believes students expected to see complete darkness, explaining that “ten percent of the sun is still going to provide daylight, and so without the glasses, you won’t notice the eclipse happening”. The next total solar eclipse will be on August 12, 2026, though it will only be visible from Russia, Greenland, Spain, and Iceland. The next to be visible from the United States will be on August 23, 2044. Although current students won’t be at Poly when it happens, hopefully they may still be able to enjoy it safely from wherever they are. VIA TJ IANNELLI
