Surge in Global Seismic Activity Highlights Persistent Threats from Earthquakes

Recent reports indicate significant global seismic activity, with multiple earthquakes and seismic-like events occurring across various locations. On November 17, 2024, the Earth experienced several notable quakes, particularly near the Pacific region and parts of the United States.

A major earthquake, measuring 6.4 on the Richter scale, struck 155 kilometers southeast of Koshima, Japan, at 9:16 PM local time. This quake was broadly felt across the region and characterized as strong. The US Geological Survey (USGS) issued alerts following this seismic activity, urging residents to remain prepared for potential aftershocks. Local authorities have not reported significant damage or injuries, but vigilant monitoring continues as smaller aftershocks are common after substantial quakes. Japan, situated on the Pacific Ring of Fire, experiences frequent seismic activity, emphasizing the importance of preparedness and emergency response protocols.

Hours earlier, another seismic-like event was reported near Riverside, California, at approximately 1:22 AM. Although preliminary reports suggest it might not be classified as a full earthquake, residents reported feeling ground movement. Seismic detection networks confirmed unusual activity at shallow depths in the region.

Cyprus experienced two separate seismic incidents on the same day. The first occurred at approximately 2:40 AM, registering as a minor 2.8 magnitude quake south of Limassol. Shortly thereafter, another seismic-like event was detected near the city. Although assessments of damage are pending, the events were relatively low in magnitude.

Undersea tremors were also recorded near the Fiji Islands, where a 4.8 magnitude earthquake occurred just south of their coastline. The event happened at 2:14 AM GMT on November 18, and no tsunami warning was issued, providing relief to those living along vulnerable coastlines.

Seismologists are examining these patterns to determine potential causes, considering whether they are part of larger tectonic shifts or isolated geological activities. Experts highlight the importance of preparedness as minor quakes often follow significant seismic activity.

Seismic activity has surged recently across the globe, with notable tremors drawing attention to the persistent threats they pose to communities. One of the recent significant events occurred near Sarmi, Papua, on November 21, 2024. The Meteorology, Climatology, and Geophysics Agency (BMKG) reported a 5.4 magnitude earthquake. Its epicenter was 56 kilometers southeast of Sarmi. Classified as shallow, the quake’s tremors were akin to the vibrations of passing trucks, according to the Modified Mercalli Intensity (MMI) scale.

Importantly, there was no tsunami threat associated with the Sarmi quake, relieving residents. However, authorities urged caution regarding buildings showing structural damage.

Prior to Papua’s event, another earthquake hit near West Java, Indonesia, on November 19, 2024, measuring 4.6. This heightened concerns among local communities following recent tremors felt in the Cianjur region.

Additionally, seismic activity was reported in Puerto Armuelles, Chiriquí, Panama, and near Kathmandu, Nepal, both experiencing unconfirmed magnitude events that stirred concerns among residents.

Indonesia and Nepal, sitting on the Pacific Ring of Fire, frequently experience seismic and volcanic activities due to tectonic plate interactions. These realities underscore the importance of disaster preparedness and community education to mitigate danger.
