Listening, this is the difference between tsunami alert, advice and watch

Jakarta – A tsunami warning was recently released to an earthquake of size (m) 7.4 that shook the southeastern region of the Philippines. This strong shaking was traced as a minor tsunami in Talaud, North Sulawesi (Sulut). The Meteorology, Climatology and Geophysics Agency (BMKG) also performed modeling to identify the potential for a tsunami. Earthquake and Tsunami director BMKG Daryono, Daryono, said the modeling results show the potential for a tsunami with a warning level (maximum height of 50 cm) covering the Talaud Islands, Bitung City, Southern Minahasa, Southernhasa and Supiori. “The modeling results show that this earthquake has the potential for a tsunami, with a warning level in the Talaud Islands, Kota-Bitung, South Minahasa-North, South Minahasa and Supiori,” Daryono said on Friday (10/10/2025).

So what is the basic difference between tsunami advice and other warning levels, such as tsunami alert to Tsunami Watch? According to the US National Weather Service (NWS), there are four most important tsunami warning levels to get to know the Tsunami warning levels. Each of these levels has a different meaning, level of danger and reaction. The following is an outline of the four levels. 1. Tsunami Warning: Danger and Evacuation! This is the most serious level. A tsunami that has the potential to cause widespread floods and very strong streams are expected to occur or currently occur in coastal areas. This dangerous condition can take several hours. Actions to take: move away from beaches and waters immediately. Move to higher areas (highlands) or to land far from the coastline (interior). Follow all evacuation instructions from local authorities. 2. Tsunami Advice (Advice/Advice): Beware of water! This level indicates the potential for strong streams and waves that are dangerous to people in or very close to the water. Coastal areas, beaches and ports may experience minor floods or unusual streams. Actions to take: Stay out of the water and stay away from coastal areas and waterways (rivers, channels, estuaries). Follow advice from local officials to remain vigilant. 3. Tsunami Watch: Get ready! An earthquake that has the potential to activate a distant tsunami has occurred, but the threat to coastal areas is still uncertain and is currently intensive monitoring. Action to take: Stay alert and monitor the latest information from official sources. Prepare yourself and your family to act (evacuate) if the warning is increased to a higher level. 4. Tsunami Information Statement: Safe is issued this level after an earthquake has occurred. This means that no tsunami threat has been detected, or that the threat is very far and its impact cannot be determined. This statement was issued when no threat to a devastating tsunami was expected. Action to take: Stay calm. No special evacuation or preparedness measures are required. The importance of understanding natural warnings Tsunami warnings, either in the form of a warning, advice or watch, can be updated or canceled as more accurate information becomes available. The warning level can also be increased if the threat is considered greater than initially estimated. In addition to relying on official warning systems, it is strongly encouraged to understand natural warnings, and people who are broadcast via radio, television, authorities (such as BMKG) and sirens living on the coast. Because there is not always enough time to wait for the official warning. Therefore, if you are on the beach and suddenly feel one of the following: feel a strong or long -lasting earthquake. See a sudden and unusual rise or drop in sea level (sudden low tide). Hear a loud and strange roar from the sea. These three things are natural warnings that a tsunami can occur soon. Don’t wait for official instructions. Take steps immediately to move to a higher, safer ground. (Wia/IDN)
