Indonesia rolls out JRC-designed system to enhance Tsunami Early Warning
Indonesia has announced plans to roll out a tsunami early warning system based on the Inexpensive Device for Sea Level Monitoring (IDSL).
The system was developed by the European Commission’s Joint Research Centre with support from the Commission’s department for European Civil Protection and Humanitarian Aid Operations (DG ECHO).
The new plan for IDSL installation foresees the acquisition of 100 new units before the end of 2020 and a more ambitious implementation of an additional 530 units over the coming years, for fisheries, ports and conservation areas across Indonesia.
The IDSL is already installed in 7 locations in Indonesia (Sebesi Island, Marina Jambu, Pandangaran, Sadeng Port and Pelabuhan Ratu on Java Island and Bungus Port on Sumatra Island). It is also being installed in Mentawai Island.
The initiative is part of a collaboration between the JRC, DG ECHO and the Ministry of Maritime and Fisheries, initiated in 2019 when the JRC provided Indonesia with 8 IDSL devices to quickly implement a new Tsunami Warning System in the aftermath of the Anuk Krakatau volcano explosion on 22 Dec 2018. The event triggered a severe Tsunami, killing more than 400 people in the Sunda Strait.
The JRC began developing the IDSL in 2014. It has been installed in 35 locations in the Mediterranean Sea to enhance the monitoring capability of the Tsunami Warning Centres, in collaboration with local institutions and the UNESCO International Oceanographic Commission.
The characteristics of this innovative device are:
its low cost (2.5 k Euro vs 25-30 k Euro of similar devices);
the quick response and transmission (latency less than 5s from measurement to data publication);
the easy installation (less than 2h);
the presence of a software onboard able to detect Tsunami waves or other large sea level variations and send email and SMS to a prescribed list of recipients.
The name of IDSL has been modified to ‘PUMMA’ in the Indonesian language, or Perangkat Ukur Murah untuk Muka Air (Low cost Device for Sea Level Measurement).
It has the same meaning but is easier for Indonesians to recognise and understand its functioning.
Announcing the plans, Indonesian Maritime and Fisheries Minister Edhy Prabowo referred to the geographical position of Indonesia and indicated: “This situation prompts the Indonesian government to formulate a practical tsunami mitigation regime because a large number of coastal communities and villages could be left vulnerable and devastated when a tsunami strikes. In addition, vast coastlines and a large number of coastal communities means that Indonesia needs tsunami early warning systems to be installed in many tsunami prone areas. In this situation, the government needs to develop a tsunami mitigation program that includes the participation of the communities to develop their preparedness and make them more resilient to tsunami."
The new devices will be built with the collaboration of the European Commission and the involvement of local small scale companies and universities.
They will be integrated with the overall monitoring network in Indonesia provided by BIG (Sea Level Monitoring Institution) and BMKG (Tsunami Service Provider).
The IDSL (or PUMMA) will be implemented not only for tsunami early warning, but also for monitoring of fisheries port activities, marine tourisms, marine ecosystem and sea level rise.
Climate change-fueled weather disasters: Costs to state and local economies
The US Government Accountability Office (GAO) estimates that between 2005 and 2019, the federal government, including FEMA and other agencies, has spent at least $450 billion on weather disaster assistance, an average of $30 billion per year (GAO 2019). It is easy to imagine that, in the face of the COVID-19 pandemic, a similar level of aid may not be available for weather disaster assistance.
The report draws on a growing body of climate science research that connects climate change to worsening weather disasters; shifting climate conditions in response to greenhouse gas emissions have been linked to fiercer storms, heatwaves, droughts, and wildfires.
To gain insight into the price Americans are paying for worsening weather disasters, it summarizes data from the National Oceanic and Atmospheric Administration (NOAA) Billion-Dollar Weather and Climate Disasters database and other public sources.
NOAA has tracked the costs of the most extreme weather events in the United States since 1980, estimating the total direct cost of each event that caused $1 billion or more in damage (adjusting all costs to 2019 dollars). No state is untouched by these billion-dollar disasters.
The analysis includes projections of future increases in the intensity and frequency of weather disasters—should governments, corporations, and citizens fail to take action to curb greenhouse gas emissions. Cities, states, and regions also need to work together to build resilience to future weather disasters.

Policy brief: technologies for averting, minimizing and addressing loss and damage in coastal zones
Coastal zones are home to about 40 per cent of the world’s population, living within 100 km of the coastline.
The most recent technology needs assessment indicates that one-third of developing countries placed infrastructure, including in coastal zones, as a prioritized sector, and most of the prioritized technologies in this regard were related to coastal protection, including both hard and soft measures.
Today more than 600 million people live in coastal zones that are less than 10 meters above sea level, and approximately 60 per cent of the world’s metropolises whose populations exceed 5 million people are located within 100 kilometers of a coastline. Coastal zones are a critical component of national economies, including shipping, aquaculture, tourism and other coastal services and industries.
Furthermore, entire economic activities in those of small islands developing states and low-lying delta countries, belong to their coasts. And yet coastal areas stand at risk from rising sea level and extreme weather intensity caused by climate change.
Recently as evidenced in many coastal areas, the impacts of these climate change phenomena, including the losses and damages, are increasingly becoming disruptive.
The report aims to inform policy-makers and practitioners on technological solutions to assess and manage climate-related risks comprehensively in coastal zones. It also identifies recovery and rehabilitation measures to address the impacts from tropical cyclones, storm surges, sea level rise, ocean acidification and other climate-change-related impacts.
