EARTHQUAKE STATISTICS

Average number of earthquakes

Based on data from the past 54 years and our earthquake archive back to 1900, there are about 117 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):

Mag. 6 or higher: 0.04 quakes per year (or 1 quake every 25 years)
Mag. 5 or higher: 0.63 quakes per year (or 1 quake every 1.6 years)
Mag. 4 or higher: 3.3 quakes per year
Mag. 3 or higher: 27.6 quakes per year
Mag. 2 or higher: 106 quakes per year (or 8.8 quakes per month)
Mag. 1 or higher: 117 quakes per year (or 9.7 quakes per month)

The area where this quake occurred has a high level of seismic activity. It has had at least 5 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 20 to 25 years.

PREVIOUS QUAKES IN THE SAME AREA OF THIS EARTHQUAKE

The earthquake occurred 9 days after a magnitude 3.4 earthquake had hit on Sunday, Aug 18, 2024, at 08:59 am (GMT +8 local time) in 19.3 km (12 mi) distance to the southeast:
Mag. 3.4 earthquake 037 km N 70° E of Divilacan (Isabela) – Aug 18, 2024 – 9 days ago
The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 7.0. It had occurred 2 years earlier, on Wednesday, Jul 27, 2022, at 08:43 am local time (Asia/Manila GMT +8) in Cordillera,  Philippines:
Mag. 7.0 earthquake Abra – Ilocos, Philippines – Jul 27, 2022 – 2 years ago
The strongest-ever (since 1900) recorded quake in this area measured magnitude 7.7. It had occurred 34 years ago earlier, on Monday, Jul 16, 1990, at 03:26 pm local time (Asia/Manila GMT +8) in Central Luzon,  Philippines:
Mag. 7.7 earthquake Luzon – Philippines – Jul 16, 1990 – 34 years ago
Below is a list and map of (larger or recent) quakes that had occurred near the area of the epicenter before this earthquake (within up to 100 km/61 mi distance, up to 300 km/183 mi for very large quakes above mag. 7). Filter the list to limit the number to show, by magnitude or time before.
