Japan has issued its first warning regarding the potential for a "megaquake" following a 7.1-magnitude earthquake that struck off the southern coast near Miyazaki Prefecture. The earthquake occurred at 4:42 p.m. local time at a depth of approximately 18 miles, prompting a tsunami advisory, although no significant damage or injuries were reported initially. Three individuals sustained injuries, and while there were minor reports of damage, including landslides and broken windows, the overall impact was relatively light. The Japan Meteorological Agency held an emergency meeting to assess the quake's implications for the nearby Nankai Trough, known for causing severe earthquakes in the past. Officials have urged residents to remain vigilant and prepared for potential evacuations. Tsunami waves of up to 1.6 feet were recorded, but the advisory indicated that waves would not exceed 1 meter. All nuclear reactors in the affected regions were reported to be safe. Japan, situated on the Pacific "Ring of Fire," is highly susceptible to seismic activity, with a history of devastating earthquakes.

The Central U.S., notably the New Madrid region, harbors a puzzling earthquake hotspot due to ancient fault lines. Scientists struggle to predict future events, warning of a 25-40% chance of a significant earthquake in 50 years. Cities like Memphis and St. Louis face heightened vulnerability.

Japan recorded its hottest July ever, with temperatures averaging 2.16 degrees Celsius above normal. The extreme heat is attributed to a high-pressure system and warm air, with ongoing risks of heatstroke.

Japan issues advisory over possible Nankai Trough megaquake
Japan has issued its first advisory for the Nankai Trough after a 7.1-magnitude quake, warning of increased earthquake risk, urging public preparedness, and highlighting potential extensive casualties and economic damage.
Japan issues first-ever alert over risk of Nankai Trough megaquake

8 comments>The Japanese government estimates that a major earthquake on the Nankai Trough would cause 169.5 trillion yen in direct damage and 50.8 trillion yen in economic losses for the following year. A study by the Japan Society of Civil Engineers in 2018 estimated that the long-term damage from the earthquake could result in 1,240 trillion yen in economic losses over a 20-year period.[11] It is predicted that the economic damage is likely to be 10 times higher than for the 2011 Tōhoku earthquake and tsunami.[12] A death toll as high as 230,000 has been suggested for such an event.[13]
Early warning / evacuation can reduce casualty by 80%+. 1240T yen = 8.5T USD. 1.5T direct+next year loss = 40% of GDP, with another 160% over next 19 years. Stupendous numbers.
>Information from the agency on Nankai Trough megaquakes is delivered at two levels — an alert and a higher warning. The weather agency issued the lower level alert on Thursday, urging people to be prepared for cases requiring evacuation. No evacuations are required for the alert level.
> A warning means people would need to be on higher alert, and officials would urge those who wouldn’t be able to evacuate quickly to do so before any large quake occurs.

I would say no, but it would imagine geologists would not say it's impossible?
