So far, we have received 9 reports for this quake from Chile. Out of these, 8 people indicated they felt it. The quake was reported to have been felt in up to approx. 160–190 km (99–118 mi) distance, with isolated cases to have felt the quake even 195 km (121 mi) away.Most reports came from Valparaiso (2 reports), a city with more than 280,000 inhabitants in 68 km (42 mi) distance northeast of the epicenter, Chile, Santiago (2 reports), the capital of Chile with 4,800,000 inhabitants in 118 km (74 mi) distance east of the epicenter, and Vina del Mar (1 report) (72 km or 45 mi to the northeast) in Region de Valparaiso.

It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.Read more about the MMI scale!Number of reports by intensityShaking intensityNumber of reportsMin-Max distance from epicenter (*)Average distance (*)I: Not felt1121–121 km (75–75 mi)121 km (75 mi)II: Very weak shaking2118–195 km (73–121 mi)156 km (97 mi)III: Weak shaking558–118 km (36–74 mi)78 km (49 mi)IV: Light shaking177–77 km (48–48 mi)77 km (48 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (9 in total) could be used for geographic statistics.Get the Android appI didn't feel itI felt this quakeIf you were near the epicenter and felt it, please share your experience and submit a short "I felt it" report!

When aftershocks are detected, we will update this section.What are aftershocks?Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.[More info]What about this quake?Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface area of approximately 5 km2 (2 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 4 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Aug 1, 2026 09:21 pm (GMT -4)13 minutes ago - felt4.717 km0 km - This quakeOffshore Valparaiso, ChileMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake
