Key findings
Twelve findings carry the baseline. They are grouped by system, never ranked. Each resolves to its source or, where Nexus analysis is involved, to its stated method.

2.1Headline finding
ReportedEQL 5NRF-REGIONAL-ASN-2026-BASELINE-CLI-003
The magnitude 7.7 earthquake near Mandalay on 28 March 2025 killed at least 3,791 people in Myanmar and at least 63 in Thailand, injured at least 5,106 in Myanmar and damaged an estimated 55,000 homes, with damage valued at US$1.9 billion.
| Item | Bar, scaled to the largest value | Value |
|---|---|---|
| Myanmar | 3,791 | |
| Thailand | 63 |
Source: US Geological Survey17. Thailand’s deaths were mainly in the north and the Bangkok area. The record also reports damage to high-rise buildings in Ho Chi Minh City.
Implication
A single rupture of about 500 km on the Sagaing Fault was felt across four countries. Health services, housing, power and water failed in Myanmar, and building damage reached Bangkok and Ho Chi Minh City. Response and insurance therefore need to be read across borders17.
What would move it
Reconstruction progress, the AHA Centre’s response records and any member-level loss series would each move this finding. Losses by member are not bound21.
2.2Systemic
EstimatedEQL 4NRF-REGIONAL-ASN-2026-BASELINE-SYS-001
The eleven ASEAN member states had about 700.3 million people in 2025 and a combined output of about US$4.27 trillion at current prices; Indonesia held 40.8% of the people and 33.9% of the output.1226
Expert inputEQL 2NRF-REGIONAL-ASN-2026-BASELINE-SYS-012
The leading compound pathway for 2027 testing is a strong dry season in which fire haze, urban heat and power demand coincide across the southern archipelago and the Malacca Strait. §9.3
2.3Climate forcing
ReportedEQL 4NRF-REGIONAL-ASN-2026-BASELINE-CLI-002
Asia’s 2025 mean temperature was 0.96 °C above the 1991–2020 average, marine heatwaves covered more than 10 million km² of ocean in July to September, and prolonged flooding in Viet Nam caused at least 200 deaths and US$1.9 billion of losses.16
ReportedEQL 5NRF-REGIONAL-ASN-2026-BASELINE-CLI-003
The magnitude 7.7 earthquake near Mandalay on 28 March 2025 killed at least 3,791 people in Myanmar and at least 63 in Thailand, with damage estimated at US$1.9 billion.17
ReportedEQL 3NRF-REGIONAL-ASN-2026-BASELINE-CLI-004
Cyclone Senyar, formed in the Malacca Strait in November 2025, brought severe flooding to parts of Indonesia, Thailand and Malaysia; an interim Indonesian count stood at 174 deaths in Aceh, North Sumatra and West Sumatra.1625
ReportedEQL 4NRF-REGIONAL-ASN-2026-BASELINE-CLI-005
The haze alert for southern ASEAN was raised to Level 3 on 26 August 2026, after 287 and 190 hotspots in Kalimantan and 65 and 81 in Sumatra on 24 and 25 August, and Sumatra recorded its highest July hotspot count in five years in 2025.4823
EstimatedEQL 3NRF-REGIONAL-ASN-2026-BASELINE-CLI-008
The eleven states emitted about 3,228 Mt CO₂e excluding land use in 2024; Indonesia emitted 41.0%, Viet Nam 18.1% and Thailand 13.1%.5
2.4Health
ReportedEQL 4NRF-REGIONAL-ASN-2026-BASELINE-HLT-006
Fine-particle exposure in 2023 ranged from 7.6 µg/m³ in Brunei Darussalam to 35.1 µg/m³ in Myanmar, and air-pollution deaths in 2019 reached 202.8 per 100,000 in the Philippines.612
2.5Energy
ReportedEQL 4NRF-REGIONAL-ASN-2026-BASELINE-ENE-007
In 2024 fossil fuels supplied 85.1% of Indonesia’s electricity and 70.5% came from coal, while renewables supplied 15.6% of the region’s primary energy in 2022 against a 23% target for 2025.818
2.6Water
ReportedEQL 4NRF-REGIONAL-ASN-2026-BASELINE-WAT-009
Renewable internal freshwater was 106 m³ per person in Singapore and 25,190 m³ in Lao PDR in 2022, and 30.5% of Indonesians used safely managed drinking water in 2024.1013
2.7Food
EstimatedEQL 3NRF-REGIONAL-ASN-2026-BASELINE-FOO-010
Ten reporting states produced about 234.2 Mt of cereals in 2024, and agriculture employed 68.6% of workers in Lao PDR and 45.0% in Myanmar in 2025.11
2.8Biodiversity
ReportedEQL 4NRF-REGIONAL-ASN-2026-BASELINE-BIO-011
Forest covered 50.7% of Indonesia’s land in 2024 and terrestrial protected areas covered from 4.6% of land in Singapore to 39.9% in Brunei Darussalam in 2025.9
