Seychelles — Natural Disaster Report

Africa · Live status: High (1 active event)

Alerts for Seychelles

Current situation: 1 natural disaster event is currently monitored in Seychelles, with a worst severity of Severe. Details, sources and timestamps are listed below.

Seychelles is a low-lying island nation where most infrastructure sits on narrow coastal plains, making sea-level rise, storm surge and coastal erosion the central long-term hazards. The islands lie outside the main cyclone track but are affected by tropical systems and by heavy swell events. The 2004 Indian Ocean tsunami caused flooding and damage. Landslides occur on the steep granite slopes of Mahé during intense rainfall, and drought affects water supply during dry periods.

Official emergency authorities

What this site sees in Seychelles

Source Events here, last 12 months What it will not tell you
WMO Alert Hub (national weather services) 17 Each warning comes from one country own alerting authority, so the scale is that agency scale and is not comparable between countries. Many agencies publish no coordinates, and those warnings are placed at the centre of the country rather than where the weather is - the area name is the real answer.
GDACS (European Commission / United Nations) none Global, but deliberately selective: it alerts on disasters likely to need INTERNATIONAL response. Serious local flooding that a national agency handles alone will not appear here.
US Geological Survey none Global for earthquakes above roughly M4.5, and denser where there are more seismometers. It publishes nothing about any other hazard.
European-Mediterranean Seismological Centre none Global for earthquakes, with the best coverage in Europe and the Mediterranean. It publishes nothing about any other hazard.
NASA FIRMS none Global, but it sees only what the satellite saw on its pass, and thick cloud hides fire. A quiet day here is not evidence that nothing burned.
NASA EONET none Global and curated rather than automatic, so it is slower than the raw feeds and carries far fewer events.
MeteoAlarm (EUMETNET) none Europe only. It publishes no coordinates at all, so every warning here is placed at the centre of its country and the area name is the only reliable indication of where it applies.
NOAA Tsunami Warning Centers none These two centres warn for the US and Canadian coasts and for the Pacific and Caribbean basins. The Indian Ocean and Mediterranean have their own warning centres, which are not read here. Their routine information statements - the ones that say there is NO tsunami danger - are deliberately not imported, so an empty tsunami list means no threat was issued, not that nothing was checked.
NOAA National Hurricane Center none The Atlantic and the eastern and central Pacific only. No typhoon in the western Pacific and no cyclone in the Indian Ocean or the southern hemisphere appears here; those come from GDACS and from national services.
ReliefWeb (UN OCHA) none Global, but it reports on humanitarian RESPONSE. It arrives days after an event rather than during it, and never functions as a warning.

Not applicable here: US National Weather Service — Covers the United States only. It publishes nothing about any other country, so its absence from a country page is not an outage. ; USGS Volcano Hazards Program — United States volcanoes only - Alaska, Hawaii, the Cascades, Yellowstone, California and the Northern Mariana Islands. It says nothing about Indonesia, Iceland, Italy or anywhere else, so its silence about a foreign eruption is not a judgement about that eruption.
