Staying Prepared: April is National Earthquake Preparedness Month

As we step into April, our attention shifts to earthquake readiness, a crucial aspect of safety in earthquake-prone regions. In recognition of National Earthquake Preparedness Month, the California Governor’s Office of Emergency Services (Cal OES) is spearheading efforts to encourage residents to refresh their emergency plans and leverage tools like the MyShake App for timely alerts. With proper preparedness, earthquakes no longer have to catch us off guard.

Understanding Earthquake Preparedness in 2024: Recent Events, Risk Assessment, and Preparedness Strategies

The San Francisco Bay region faces a significant threat of a major earthquake, not merely as a statistical probability but as a stark reality demanding preparedness and proactive planning. The U.S. Geological Survey (USGS) and other scientific organizations project a 70% likelihood of at least one magnitude 6.7 or greater earthquake striking this area before 2030. The potential for widespread damage and disruption is substantial, underscoring the critical need for communities to mitigate risks and ensure safety.

Exploring Recent Significant Earthquakes: A Detailed Analysis

Several notable earthquakes have occurred worldwide recently, each classified as "significant" based on magnitude, impact, and public response. This classification considers three key factors:

1. Magnitude: The earthquake's strength determines its potential impact and damage. Higher magnitudes pose a greater risk to communities and infrastructure.

2. Public Response (DYFI): The number of "Did You Feel It" (DYFI) responses indicates the earthquake's impact on populated areas. Higher response rates suggest a larger affected population.

3. PAGER Alert Level: This categorization estimates casualties and economic losses. Higher alert levels signify severe potential consequences.

Calculating Significance

To gauge earthquake significance, a composite score is computed using:

• Magnitude Significance (mag_significance): Calculated as magnitude * 100 * (magnitude / 6.5), reflecting relative strength compared to a standardized scale.

• PAGER Significance (pager_significance): Assigned based on alert level (red = 2000, orange = 1000, yellow = 500, green = 0) indicating potential impact severity.

• DYFI Significance (dyfi_significance): Derived from DYFI responses and Community Internet Intensity Map (CDI), reflecting perceived intensity in affected areas.

The combined significance score (significance) is the maximum value among mag_significance, pager_significance, and dyfi_significance. Earthquakes with a significance score exceeding 600 are deemed "significant" and highlighted on real-time monitoring platforms.

Recent Noteworthy Earthquakes

Several recent earthquakes met the significance criteria, including:

• M 4.8 - 2024 Whitehouse Station, New Jersey Earthquake
• M 3.8 - 7 km SW of Gladstone, New Jersey
• M 7.4 - 18 km SSW of Hualien City, Taiwan
• M 6.6 - 149 km NW of Tobelo, Indonesia
• M 6.8 - Maug Islands region, Northern Mariana Islands
• M 4.4 - 6 km NW of Belden, CA
• M 6.4 - 110 km N of Paciran, Indonesia
• M 5.4 - 23 km ENE of Bileća, Bosnia and Herzegovina
• M 6.4 - 11 km NE of Hualien City, Taiwan
• M 6.4 - Vanuatu region
• M 6.9 - 38 km ENE of Ambunti, Papua New Guinea

Urgency of Earthquake Preparedness in the San Francisco Bay Area by 2030

According to the U.S. Geological Survey (USGS) and scientific research since the 1989 Loma Prieta earthquake, there is a 70% probability of a magnitude 6.7 or greater earthquake hitting the San Francisco Bay region by 2030. This highlights the critical need for ongoing earthquake preparedness efforts by Bay Area communities to mitigate risks and enhance resilience.

Importance of Emergency Preparedness

Preparation is paramount to minimizing earthquake impact. Every household and community should have a robust emergency plan addressing:

• Family Communication: Establish a strategy to connect during and after earthquakes, with designated meeting places and out-of-area contacts.

• Emergency Supplies: Stockpile water, non-perishable food, first aid kits, flashlights, batteries, and blankets for several days.

• Home Safety: Conduct a hazard hunt to identify and address dangers like unsecured furniture and flammable materials.

• Community Collaboration: Work with neighbors and local authorities to establish response plans, evacuation routes, and safe areas.

Utilizing Technology for Safety

In the digital age, technology enhances earthquake preparedness. Smartphone apps and alert systems provide real-time updates, and structural engineering advancements offer seismic retrofitting techniques to strengthen buildings.
