Tectonic Setting
The Java subduction zone has not had any large-magnitude earthquakes in the past 100 to 200 years except for an M8.0–8.5 Java Trench earthquake in 1780, which was the largest historical earthquake in the Java Trench. Recent large earthquakes in other subduction zones have cast doubt on the notion that long-term fault behavior can be inferred by as little as one century of historical earthquake records. The total convergence rate across the Java Trench is about 6 to 7 cm a year, higher than most other major subduction zones in the region [2]
