A Small but Noticeable Shake in San Francisco
A small earthquake, measuring 4.3 on the Richter scale, recently shook the San Francisco Bay Area. This event, though not very strong, was felt by many people in the region. Earthquakes of this magnitude are common in California due to its location along the Pacific Ring of Fire.
Understanding the Shaking
The shaking was categorized using the Modified Mercalli Intensity scale, which measures how strong the shaking feels on the ground. This scale helps scientists understand the impact of the earthquake on people and buildings. The data collected from this event will help researchers learn more about the area's seismic activity.
Aftershocks and Data Collection
Aftershocks are smaller earthquakes that follow the main quake. In this case, any aftershocks within 100 miles and seven days of the initial quake will be included in the data. This information is crucial for understanding the behavior of earthquakes in the region.
Visualizing the Data
The maps and charts used to display this information come from various sources. These include:
- MapLibre for map rendering
- Natural Earth for roads, labels, and terrain
- Protomaps for map tiles
These tools help visualize the data and make it easier to understand.
