Moderate magnitude 4.5 earthquake at 21 km depth15 Sep 02:15 UTC: First to report: VolcanoDiscovery after 13 minutes.15 Sep 02:16: Now using data updates from RaspberryShake15 Sep 02:20: Now using data updates from PHIVOLCSUpdate Tue, 15 Sep 2026, 02:18Moderate magnitude 4.5 earthquake 40 km northeast of Tandag, PhilippinesJust 15 minutes ago, a 4.5-magnitude earthquake struck near Tandag, Surigao del Sur, Caraga, Philippines. The tremor was recorded in the morning on Tuesday, September 15th, 2026, at 10:03 am local time, at a shallow depth of 21. km below the surface.The event was filed by the citizen-seismograph network of RaspberryShake, the first seismological agency to report it.Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.Weak shaking might have been felt in Cortes (pop. 3,000) located 23 km from the epicenter, Burgos (pop. 3,500) 24 km away, Tandag (pop. 29,000) 40 km away, Cantilan (pop. 9,400) 42 km away, Tago (pop. 6,300) 45 km away, Socorro (pop. 9,700) 48 km away, Cabadbaran (pop. 31,100) 95 km away, Bayugan (pop. 110,300) 97 km away, and Butuan (pop. 309,700) 102 km away.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.

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 (*)IV: Light shaking141–41 km (25–25 mi)41 km (25 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (1 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 3 km2 (1 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 3 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Sep 15, 2026 10:03 am (Manila)32 minutes ago4.521 km0 km - This quakePhilippine Sea, 40 km NE of Tandag, PhilippinesMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 26 years and our earthquake archive back to 1900, there are about 2,100 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.04 quakes per year (or 1 quake every 25.6 years)Mag. 6 or higher: 0.43 quakes per year (or 1 quake every 2.3 years)Mag. 5 or higher: 9 quakes per yearMag. 4 or higher: 115 quakes per year (or 9.6 quakes per month)Mag. 3 or higher: 406 quakes per year (or 33.8 quakes per month)Mag. 2 or higher: 1,600 quakes per year (or 4.3 quakes per day)Mag. 1 or higher: 2,100 quakes per year (or 5.8 quakes per day)The area where this quake occurred has a very high level of seismic activity. It has had at least 5 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 25 to 30 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeLat / Lng: 9.41 / 126.35: Philippines: 022 km N 49° E of Cortes (Surigao Del Sur)Lat / Lng: 9.41 / 126.35: Philippines: 022 km N 49° E of Cortes (Surigao Del Sur)
