Lessons from the recent devastating earthquakes
in Indonesia
Dr. Irwan Meilano
In the last three years, Indonesia has experienced several large earthquakes, which have resulted insignificant economic losses. The earthquakes were the Lombok M6.9 earthquake in August 2018, the PaluM7.5 earthquake in September 2018, the Ambon M6.5 earthquake in September 2020, and the M6.2
Mamuju earthquake in January 2021. These earthquakes had resulted in economic losses of more than 1.8
million dollars and more than 5000 people died. In this study, lessons learned from the latest earthquake inIndonesia will be discussed, especially aspects related to understanding the earthquake's source, with adetailed discussion of the 2018 Palu earthquake.
Palu's coastal area suffered a tsunami on September 28, 2018 caused by an earthquake with a magnitudeof 7.5. With a known pattern of strain accumulation and release, the potential for earthquakes due to thePalu-Koro Fault is well understood by experts. However, this understanding from the expert did not succeed
in becoming part of the community's knowledge. The survey results showed that 71% of the community did
not understand the potential for an earthquake and 84% of the tsunami's potential.
This earthquake also provides an important lesson for experts, that a strike-slip fault, if it has a fast rupture(supershear), can generate a tsunami. As well as the potential for a tsunami due to submarine landslides
associated with strong ground shaking. Another lesson learned from the Palu earthquake is that there is aneed for a system that can rapidly estimate the earthquake's magnitude by combining information from GPS
displacement and Seismic data. This rapid estimate of the magnitude can be used to estimate the impact ofa disaster quickly.

From Community and Science to Policy Change:
Improvement of Tsunami Warning Chain
Ir. Harkunti P. Rahayu, Ph.D.
In the past few decades, Indonesia have suffered a lot of casualties from tsunami. Despite having
been fully operated since 2008, the Indonesian Tsunami Early Warning System (InaTEWS) still needs extensive work especially in the downstream component. Meanwhile, the Indonesian constitution have mandated
the responsibility to save people’s lives against natural disasters to local government in the city and regency
level. In Padang City, the existing regulation related to early warning system—Padang Mayor Regulation
14/2010—mainly considers inter-agency in provincial and city level while only utilizes mass communication
ways methods such as siren and mass media for disseminating evacuation orders. This raised a problem aspeople-centered approach has been the main agenda for early warning systems and have also been shownto increase resilience. This study aims to identify the gaps in the current policy and propose a viable framework for policy improvement regarding people-centered tsunami early warning chain in Padang City. The
study found that the existed regulation lacks extension nodes to relay warnings to the last mile population.
Moreover, receiving warning information from both formal and informal sources is important to mobilize
people evacuation more effectively during an emergency. The study found that community masjid and disaster preparedness leaders are the potential actors who should be involved in the local early warning chain.
The research finding was presented as a recommendation to Padang City government and have been legalized as the new tsunami early warning chain procedure in the Padang City Mayor Regulation 19/2018.
