Earthquake that strike university of Goroka and it's historical data frequency, magnitude and it's impact on community and create a risk map of the disaster area

1 answer

To provide a comprehensive overview regarding earthquakes affecting the University of Goroka (UOG) in Papua New Guinea, it’s essential to consider historical data, potential impacts, and risk mapping.

Historical Data on Earthquakes

  1. Frequency: The frequency of earthquakes in Papua New Guinea is relatively high due to its location along the Pacific Ring of Fire. The region experiences numerous earthquakes each year, with varying magnitudes.

  2. Magnitude: Earthquakes in Papua New Guinea can range from minor tremors (below 4.0) to major earthquakes (above 6.0). Notable earthquakes affecting the Goroka area have included:

    • The 2008 earthquake with a magnitude of 7.1 near the city of Goroka.
    • A series of aftershocks and smaller quakes that followed various larger seismic events in the region.

  3. Recent Significant Earthquakes: Review recent geological survey databases, national seismic networks, or academic publications for the latest data on earthquakes in and around Goroka. Specific attention should be directed toward:

    • Dates of significant seismic events.
    • Magnitudes and epicenters.

Impact on Community

  1. Physical Infrastructure: Earthquakes can damage buildings, roads, and utilities, seriously affecting the University of Goroka's facilities and surrounding communities.

  2. Casualties and Displacement: Injuries and fatalities during significant earthquakes can disrupt community life; some may also require evacuation and temporary accommodation.

  3. Economic Impact: The local economy may suffer from the destruction of infrastructure, educational disruptions, and decreased investor confidence in the region.

  4. Psychosocial Effects: Earthquakes can lead to long-term psychological trauma within communities, affecting students, staff, and residents.

Risk Map Creation

Creating a risk map involves analyzing various factors including:

  1. Historical Earthquake Data: Plotting the locations and magnitudes of past earthquakes will help assess risk areas.

  2. Geographical Considerations: Identify fault lines, geological features, and the topography of the land around UOG.

  3. Population Density: Overlay population maps to see how many individuals might be affected in the event of an earthquake.

  4. Infrastructure Mapping: Document the locations of critical infrastructure such as water supply, hospitals, roads, and emergency services.

  5. Vulnerabilities: Assess the building standards and preparedness of the university and surrounding areas.

Risks & Mitigation Strategies

  1. Awareness and Education: Community education on what to do during and after an earthquake can mitigate injuries.

  2. Infrastructure Resilience: Ensuring that structures adhere to seismic safety standards can reduce damage in future earthquakes.

  3. Emergency Preparedness Plans: Develop and regularly update plans that include evacuation routes, emergency supplies, and communication strategies.

  4. Conducting Drills: Regular drills for students and staff that reinforce preparedness for seismic events.

Conclusion

In conclusion, addressing the earthquake risk in the University of Goroka area requires a thorough understanding of historical data, potential community impacts, and strategic risk mapping. Collaboration with local geological expertise, government agencies, and community organizations will enhance preparedness and resilience against potential seismic events. For specific data and current risk maps, consulting geology and disaster management authorities in Papua New Guinea is recommended.
