Get free Metro Manila flood + quake alerts on Nova → walang download, walang accountThree official feeds cover the metro, and each answers a different question. PAGASA issues flood bulletins for the Pasig-Marikina-Laguna de Bay and Tullahan river basins — these tell you when a river is rising. The MMDA flood-monitoring map tells you which roads are passable, gutter-deep, or impassable right now. Your city DRRMO issues local evacuation advisories for your barangay.
During the July 2025 habagat, PAGASA raised flood bulletins for the Pasig-Marikina-Laguna de Bay and Tullahan river basins as monsoon rains hit (Manila Bulletin, citing PAGASA, July 9, 2025). The lesson: ang baha sa Metro Manila ay hindi iisang bagay — iba ang flooding ng ilog sa flooding ng kalsada, kaya bantayan ang dalawa. Nova bundles NDRRMC, PAGASA, and MMDA alerts into one free push feed so hindi mo na kailangang mag-refresh ng maraming page.
Metro Manila floods from several river systems at once, not one — that is why a downpour can hit Marikina and Quezon City hard while other cities stay dry. The metro sits on a floodplain between Manila Bay and Laguna de Bay, laced by the Pasig, Marikina, San Juan, and Tullahan rivers (Project e-SMART, UP NHRC).
On August 30, 2025, severe thunderstorms dumped 121 mm of rain in a single hour over Quezon City — higher than Typhoon Ondoy's peak hourly average — flooding 36 of QC's 142 barangays and submerging Nangka, Marikina (PAGASA; Quezon City government, via GMA News and Inquirer). Even non-flood-prone streets like Mother Ignacia and Katipunan went underwater.
The West Valley Fault runs straight through Metro Manila, so most of the metro's population lives within a major earthquake's reach. According to PHIVOLCS, the roughly 100-km fault crosses Quezon City, Marikina, Pasig, Makati, Taguig, and Muntinlupa, plus nearby Rizal, Laguna, Cavite, and Bulacan.
PHIVOLCS warns the fault could generate a magnitude-7.2 earthquake — "The Big One" — that could topple up to 168,000 buildings and kill more than 33,000 people across Metro Manila and surrounding provinces (PHIVOLCS, via Daily Tribune, March 2025). No one can predict when. What you can do today: secure heavy furniture, pack a go-bag, and check whether the fault runs near you using the PHIVOLCS Valley Fault Atlas. For city-specific quake prep, see our Makati guide, and the national Lindol: Ano ang Gagawin? guide for the Duck, Cover, and Hold response.
For any life-threatening emergency anywhere in Metro Manila, call 911 — it is the single nationwide emergency number (police, fire, medical, rescue), free and 24/7, after Executive Order No. 56 replaced the old Patrol 117 network. These verified metro-wide numbers work across all 16 cities and the municipality of Pateros:
911 — National emergency (police · fire · medical · rescue), nationwide
143 — Philippine Red Cross (first aid, ambulance, blood)
136 — MMDA (traffic + road flooding, Metro Manila)
(02) 8911-1406 — NDRRMC (national disaster response)
(02) 8284-0800 — PAGASA (weather + flood advisories)
For your own city's rescue + DRRMO hotline, check your official city government site — these change per LGU and we only publish numbers we have verified. Find your city below. Save 911 first: it routes to police, fire, and medical anywhere in the country, so it is the one number to remember when seconds count. For the full national list, see our emergency hotlines guide.

Each Metro Manila city runs its own DRRMO, evacuation centers, and rescue hotline — so the safest move is to open your city's guide. We are building one per city; here are the ones live now:
More Metro Manila cities are coming — Quezon City, Marikina, Taguig, Manila, and the rest of the 16 cities plus Pateros. Until your city's page is live, watch PAGASA and MMDA, and find your city's DRRMO hotline on its official government site.
If you spot a blocked drainage canal, a flooded street, a fallen post, or a damaged road, report it to your barangay first — they are the fastest local responders. Sa Nova, pwede kang mag-report ng hazard nang libre at makikita ito sa safety map para mabalaan ang ibang residente. For the full step-by-step on escalating a problem to your barangay and LGU, see our how to report a barangay problem guide. For a life-threatening emergency, do not wait — call 911 first.
