Tropical Cyclone Seroja has triggered flooding, landslides, and extreme winds in East Nusa Tenggara, causing severe damage across the region since April 4th, 2021.
According to first-hand reports submitted to PetaBencana.id, the extreme weather has collapsed bridges, washed away homes, and caused power outages. Residents have been sharing real-time updates through the PetaBencana.id platform to help keep each other informed, and support response efforts.
According to Raditya Jati, Head of Data, Information and Communications at the National Emergency Management Agency of Indonesia (BNPB), “Extreme weather due to tropical cyclone Seroja still has the potential to occur in the East Nusa Tenggara (NTT) region in the next few days.”
We remind residents to check https://petabencana.id for up-to-date information. Residents in East Nusa Tenggara can also submit real-time flood reports by tweeting #banjir @petabencana, sending a Facebook message to @petabencana.id, or sending a Telegram message to @bencanabot. When we share what we see, everyone can stay informed, avoid danger, and reduce risk together!
On February 20th, #banjir and #JakartaBanjir were the highest trending topics on Twitter Indonesia, as the capital city was inundated for the third major time this year, following particularly heavy rainfall from Friday night (19/2/2021) to Saturday morning (20/02/2021). As Jakarta residents turned to social media to share updates about the flood, they were greeted by “Disaster Bot” – a novel AI-assisted chatbot that monitors social media for posts about disasters and automatically invites users to submit more detailed disaster reports. These crowd-sourced reports are used to map disasters in real-time, on a free and open source website, PetaBencana.id.
As flooding blocked major thoroughfares and toll roads, disrupted commuter lines, and cut off electricity to over 60,000 homes, residents continued to share updates about the flood situation in order to stay alert and make timely decisions about safety and response. Hundreds of residents submitted flood reports to PetaBencana.id, alerting each other about water levels, broken infrastructures and road accessibility. The Jakarta Emergency Management Agency also updated the map with official information about flood affected areas, and monitored the map to respond to resident needs. PetaBencana.id experienced a 2000% in activity in under 12 hours as residents actively checked the map to understand the flooding situation, avoid flooded areas, and make decisions about safety and response.
As flooding incidents continue to occur with increasing intensity across the country, community-led information sharing is once again proving its significance in supporting response and planning at multiple scales. Data from PetaBencana.id is consumed by the National Emergency Management Agency’s (BNPB) InAWARE Disaster Monitoring platform to support decision making. BPBD DKI’s application Pantau Banjir also integrates real-time flood information from PetaBencana.id to push flood updates to residents. Over the course of the weekend, several media platforms turned to PetaBencana.id as a verified information source to support news coverage about the flooding situation across Jakarta’s neighborhoods, including the Jakarta Post, Kompas, Tribun, and the Jakarta Globe, among others. Once again, this weekend’s incidents highlight the significance of community engagement in disaster information sharing.
People on-the-ground are best equipped to provide location-specific information updates, and observations arising from lived experiences are critical to gain insight on how we collectively respond to the changing behavior of floods in the city. One of the most common observations shared by residents was the persistence of flood waters in their neighborhoods even several days after the rain had stopped; an observation that can be attributed to the increased concretization of the city and overflowing canals.
Yayasan Peta Bencana thanks all residents of Indonesia for continuing to share critical information, and applauds the indispensable role of all residents in helping neighbors, government agencies, responders, and researchers develop strategies for climate adaptation.
As BMKG predicts extreme rainfall to continue until April, Dwikorita Karnawati, Head of BMKG, emphasizes the need for improved coordination and synergy between multiple stakeholders for climate adaptation efforts.
Residents of Indonesia can submit real-time flood reports by tweeting #banjir @petabencana, sending a Facebook message to @petabencana.id, or sending a Telegram message to @bencanabot. We remind everyone to check https://petabencana.id for up-to-date information and to stay safe!

PetaBencana.id is supported by the U.S. Agency for International Development (USAID). The project is made possible through collaboration with project partners including the Pacific Disaster Center at the University of Hawaii, the Humanitarian OpenStreetMap Team, and Civic Data Lab; our implementing partners at the National Emergency Management Agency (BNPB) and Jakarta Emergency Management Agency (BPBD DKI Jakarta); and, our data partners including Mapbox, Twitter, Qlue, and PasangMata.
Five consecutive typhoons struck the Philippines in late October and early November. Still recovering from damages brought about by Typhoon Molave (Quinta), Typhoon Goni (Rolly), Typhoon Atsani (Siony), and Typhoon Etau (Tonyo), the rain-drenched eastern and northern portions of the country endured excarbarated impacts from Typhoon Vamco (Ulysses), the fifth major storm to hit the region in just two weeks.
These typhoons left major roads impassable due to flooding and affected electrical and communication powers. Major dams in the country have reportedly worsened the flooding situations in the downstream areas of Cagayan Valley, Central Luzon, the Cordillera Administrative Region and Metro Manila.
In the midst of the massive flooding situation, which paralyzed major thoroughfares and stranded thousands of Filipino commuters, hashtags #FloodPH and #RescuePH trended on social media, with people calling for help and posting information about the flood situation in their area. MapaKalamidad.ph, a recently launched disaster information sharing platform in the Philippines, is harnessing the active use of social media to support community-led risk reduction. Using AI-assisted chatbots to monitor and respond to social media posts, the platform gathers confirmed crowd-sourced reports from residents to map flooding in real-time. The platform experienced a significant increase in activity during Typhoon Ulysses as residents actively shared real-time situational updates about the flood. The free web-based map was used to support residents and disaster management units identify the areas that needed immediate response and rescue efforts. MapaKalamidad.ph was launched last September 2020 as part of the PhilAWARE Program with support from the U.S. Agency for International Development Bureau of Humanitarian Affairs (USAID BHA) in partnership with the Philippine Office of the Civil Defense (OCD), Pacific Disaster Center (PDC), and Humanitarian OpenStreetMap Team (HOT).
According to Joseph Curry, from USAID BHA, “While we depend on the government to be the authoritative source on damages and needs, we also recognize that those affected have the most up to date information and have an essential role to play. MapaKalamidad.ph adds a new dimension to data and information collection by empowering citizens to directly report hazards, critical lifelines and damages in their neighbourhoods via social media apps and mobile apps. In the true spirit of bayanihan, MapaKalamidad.ph gives us a tool that everyone can use together in disaster response, potentially connecting every barangay right to the top.”
The unpredictable behavior of the recent typhoons have highlighted the necessity for verified real-time information to support response efforts in rapidly fluctuating conditions. As storms quickly changed course and floodwaters inundated the country, netizens shared the platform has a great potential in becoming the primary information source to share real-time flood map to make more informed decisions on safety and response.
MapaKalamidad.ph is currently available to residents in Quezon City and Pampanga where residents can share flood information anonymously by sending a Facebook message to @mapakalamidad, tweeting #flood or #baha to @mapakalamidad, or sending a Telegram message to @kalamidadbot. Government emergency management agencies also monitor the map to assess the disaster situation and respond to the needs of the residents.
With La Nina conditions expected to continue, heavy rainfall is expected throughout the region over the next few months. Yayasan Peta Bencana encourages residents of the Philippines to continue sharing critical information to help their neighbors, government agencies, and emergency responders in times of disaster events.
We remind everyone to check https://mapakalamidad.ph for up-to-date flood information to stay safe!

Powered by CogniCity Open Source Software, PetaBencana.id is a free web-based platform that produces megacity-scale visualizations of disasters using both crowd-sourced reporting and government agency validations in real time. The platform harnesses the heightened use of social media and instant messaging during emergency events to gather confirmed situational updates from street level, in a manner that removes the need for expensive and time consuming data processing. These verified user reports are displayed alongside relevant emergency data collected by local and government agencies. By integrating localized knowledge from a variety of sources into a single, robust platform, PetaBencana.id is able to provide a comprehensive overview of disaster events, enabling residents, humanitarian agencies, and government agencies to make more informed decisions during emergencies.
Since its debut in 2013 (as PetaJakarta.org), the PetaBencana.id platform has been used by millions of resident users to make time-critical decisions about safety and navigation during emergency flood events; it has also been adopted by the National Emergency Management Agency (BNPB) to monitor flood events, improve response times, and share time-critical emergency information with residents. The platform has enabled greater information sharing and data coordination among residents and government agencies, fostering equitable and collaborative resilience to climate change.
PetaBencana.id has proven that community-led data collection, sharing, and visualization reduces flood risk and assists in relief efforts. In the 2015 World Disaster Report of the International Federation of the Red Cross, the project was recommended as a model for community engagement in relation to disaster response. In 2016, the Federal Communication Commission of the United States also recommended the project as a best practice regarding disaster information crowdsourcing. PetaBencana.id is now available for all residents in Indonesia!
