2023-01-09, M7.6, Indonesia

On the 9th of January 2023 an M7.6 earthquake occurred in the Tanimbar region of Indonesia (see map below). Several aftershocks were also reported after the powerful quake that was also felt in some parts of northern Australia.

Indonesia is positioned at the boundary of 3 tectonic plates (the Indian-Australian, Eurasian and Pacific plates). The plate boundaries are long and found beneath the ocean, meaning large and shallow earthquake can be generated from this zone that may potentially generate tsunami.

The event was recorded by seismic stations worldwide, including stations in theĀ Irish National Seismic Network (INSN), see figure below.

2022-11-21, M5.6, Indonesia

On the 21st of November 2022, an M5.6 earthquake occurred at 06:21:11 UTC approximately 18 km WSW of Ciranjang-hilir, Indonesia, see map below. The event occurred in a densely populated region and resulted in over 200 fatalities and over 1,000 injured people largely due to buildings collapsing.

This is a highly seismically active region, close to the subductive plate boundary between the Australia and Sunda plates. The earthquake occurred within the crust of the Sunda plate approximately 260km northeast of the boundary.
