MANILA, Philippines – The Philippine Institute of Volcanology and Seismology (Phivolcs) has issued a tsunami advisory for coastal communities facing the Pacific Ocean, following a significant earthquake that struck Russia. While the potential tsunami wave height is currently estimated to be less than one meter, authorities are urging vigilance and precautionary measures.

The earthquake, which registered a considerable magnitude, originated in Russia and generated concerns about potential tsunami impacts across the Pacific region. Phivolcs closely monitors seismic activity and assesses the risk of tsunami generation, issuing alerts when necessary to protect vulnerable coastal populations.

What You Need to Know:

• Tsunami Advisory: A tsunami advisory means that a tsunami is possible, and coastal areas should remain alert.
• Expected Wave Height: Phivolcs anticipates tsunami wave heights of less than one meter along the Philippine coastline. While this is considered a relatively low height, even small tsunamis can pose risks, particularly in areas with shallow coastal waters.
• Affected Areas: The advisory primarily concerns coastal areas in the Philippines that directly face the Pacific Ocean.
• Precautionary Measures: Residents in affected areas are advised to stay informed, monitor official updates from Phivolcs and local authorities, and be prepared to move to higher ground if necessary.

Understanding Tsunami Risks

Tsunamis are a series of ocean waves caused by large-scale disturbances, such as earthquakes, volcanic eruptions, or underwater landslides. Even relatively small tsunami waves can be dangerous due to their long wavelengths and the potential for strong currents. The impact of a tsunami can vary significantly depending on local coastal topography, bathymetry (underwater terrain), and other factors.

Phivolcs' Role in Tsunami Preparedness

Phivolcs plays a crucial role in the Philippines' tsunami preparedness efforts. The institute operates a network of seismic monitoring stations and tide gauges to detect earthquakes and monitor sea levels. Upon detecting a potential tsunami-generating event, Phivolcs assesses the risk and issues alerts and warnings to relevant government agencies and the public. The institute also conducts public awareness campaigns to educate communities about tsunami hazards and preparedness measures.

Staying Safe: What to Do

• Stay Informed: Monitor official updates from Phivolcs, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), and local disaster risk reduction and management offices.
• Move to Higher Ground: If a tsunami warning or advisory is issued, immediately move to higher ground or inland, away from the coastline.
• Be Aware of Natural Signs: Be alert for natural signs of a tsunami, such as a strong earthquake, a sudden rise or fall in sea level, or a loud roaring sound coming from the ocean.
• Follow Instructions: Follow the instructions of emergency responders and local authorities.

The situation is being closely monitored, and further updates will be provided as more information becomes available. The safety and well-being of coastal communities remain the top priority.
