Today's #earthquake in W Java has a strike-slip mechanism according to moment tensor solution by BMKG, Indonesian Meteorology, Climatology, and Geophysical Agency - https://inatews.bmkg.go.id/
See map 👇🏼 with the "beach ball" showing the fault mechanism with two possible very steep fault planes.
Hypocenter shallow depth ~11km and closeness to Cianjur town (less than 10km), where damages are reported, likely explains its destructive character. Strong shaking also reported in Jakarta at ~80km from the epicenter.
This recalls that even in contexts like #Java or #Sumatra, where the #subduction #megathrust may produce very big #earthquakes, much smaller shallow crustal ruptures may present significant hazards because closer to towns.
