DESCRIPTION:This presentation explores the exposure of Southern Leyte's Pac
 ific towns to potential earthquake-induced tsunamis. Earthquakes\, a natur
 al catastrophe resulting from tectonic plate movements or volcanic eruptio
 ns\, often lead to tsunamis\, posing severe threats in unprepared regions.
  The Philippines\, due to its geological makeup\, faces recurrent earthqua
 kes and the risk of tsunamis.\nHighlighting past tsunami incidents in the 
 Philippines\, like the 1994 Mindoro earthquake and the 1976 Cotabato trenc
 h earthquake\, this presentation emphasizes the need for tsunami risk asse
 ssment. Spatial analysis is vital to identify vulnerable areas based on fa
 ctors such as earthquake magnitude\, depth\, and proximity to the shorelin
 e.\nThis study employs spatial mapping techniques\, using earthquake data 
 from USGS and geographic data from open data sources. QGIS software\, an o
 pen source mapping software\, processes the data\, producing maps illustra
 ting earthquake depth and magnitude. Heatmaps identify high-risk zones bas
 ed on earthquake depth concentration. Temporal analysis reveals an increas
 ing trend in earthquake occurrences\, particularly in recent years.\nUnder
 standing earthquake behavior and its relation to tsunamis is crucial for p
 reparedness and mitigation. Identifying high-risk areas enables the develo
 pment of strategies to reduce tsunami impacts\, emphasizing risk managemen
 t over crisis response. Learning from past experiences and conducting comp
 rehensive studies are essential steps toward earthquake-induced tsunami pr
 eparedness in vulnerable regions like Southern Leyte's Pacific towns.
