Under land 140 kilometer from Jayapura in Indonesia, a significant MAG-5.3 earthquake occurred in the early morning of Monday November 13th, 2023.
The earthquake struck on land in Indonesia, 140 kilometer (87 mi) south-southwest of Jayapura in Papua. The center of this earthquake had a quite shallow depth of 40 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

More earthquakes coming?
Earthquakes can create aftershocks. These are generally at least 1 magnitude lower than any main shock, and as time passes the chance and strength of aftershocks decreases.
The chance that a significant earthquake like this one is followed by an even larger earthquake is not so large. On average, scientists estimate a 94% chance that a major earthquake will not be followed by an even larger one. It is still adviced to be aware of this riskRead: How to Stay Safe during an Earthquake (cdc.gov).
Earthquakes like this happen often in the region
Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since July 3rd, 2023, when a 5.4 magnitude earthquake hit 10 km (6 mi) further south-southwest. An even stronger magnitude 7 earthquake struck on July 27th, 2015.
In total, 53 earthquakes with a magnitude of 5.3 or higher have been registered within 300km (186 mi) of this epicenter in the past 10 years. This comes down to an average of once every 2 months.
Tsunami very unlikely
While MAG-6.5+ earthquakes may cause tsunami's, it appears that the epicenter of this earthquake hit under land. In addition, the reported depth is deeper than 100km, making the risk of a tsunami even less likely. However always stay cautious and monitor advice from local authorities.
Tsunami Risk Factors
|Factor||Under Sea?||MAG-6.5 or stronger?||Shallow depth?|
|Explanation||Almost all tsunami's are caused by earthquakes with their epicenter under sea or very near the sea. However stay cautious in coastal areas as earthquakes on land may cause landslides into sea, potentially still causing a local tsunami.||Under MAG 6.5: Very unlikely to cause a tsunami.
MAG 6.5 to 7.5: Destructive tsunami's do occur, but are uncommon. Likely to observe small sea level changes.
MAG 7.6+: Earthquakes with these magnitudes might produce destructive tsunami's.
|Most destructive tsunami's are caused by shallow earthquakes with a depth between 0 and 100km under the surface of the earth. Deeper tsunami's are unlikely to displace to ocean floor.|
|This Earthquake||Not this earthquake.
This earthquake appears to have struck on land far from any coast.
|Not this earthquake.
This earthquake had a magnitude of 5.3. Earthquakes of this strength are unlikely to trigger a tsunami.
|This earthquake occurred at a depth of of 40 km (25 mi). Earthquakes this shallow could trigger a tsunami.|
