Recent large earthquakes, including the M7.4 in Colombia on August 10 and M7.7 in Indonesia on August 14, have elevated aftershock sequences that could add several M5.5+ events during August 17–23, pushing counts above typical background rates. Global M5.5+ frequency averages roughly 6–10 per week based on USGS catalogs, with Poisson-like variability and clustering in subduction zones along the Ring of Fire driving the spread across market bins. Aftershock productivity follows Omori’s law, decaying over days to weeks, while any new mainshocks or foreshock activity remain uncertain; traders weigh ongoing sequences against quiet periods in other regions when assessing the close probabilities for 7–10 versus extremes below 7 or above 13.
