Excited to share our new publication in Tectonophysics! We present updated active-fault mapping and paleoseismic evidence from the Aceh Fault, advancing our understanding of seismic hazard in northern Sumatra. Read here: authors.elsevier.com/a/1m7C%7E98w...

Some damage has been reported in Karang Teko, Wongsorejo. Video source: Farhan Hidayat, BPBD Probolinggo

Mapped aftershocks are clustering along a NE-SW trend

The focal mechanism just came out (GFZ) shows a strike-slip style, the nearby Baluran Fault north of the epicenter is mapped NE–SW, there might be some complexity, it can be unmapped structure at play, i'lll keep following as more data & local reports come in.

A M5.7 shallow eq hit off the coast near Situbondo, East Java this afternoon. Felt pretty strong in Banyuwangi & Bali, also reported in Lombok, Surabaya, even Madura.  Reports of damage are starting to come in—will keep this thread updated as we learn more. Stay safe, everyone!

Fold and waterfall: nature's way of spoiling geologist 😀

Quite impressive storm cloud, a moment before it rains hard, we're in Nagan Raya, the Batee Fault scarp is just behind us

I went back and forth to North Sumatra in the past few months, studying the paleoseismology of the Aceh, Seulimeum and Batee Fault of the Sumatran Fault Zone. Do I need to tell you why I love this beautiful place? I'll follow up with more stories!
