Visualizing Earthquakes

[rasagy]

For the final assignment, let’s use the USGS Earthquake Catalog to visualize earthquakes on a map.

For the assignment, try to narrow down on the three filters for your narrative: Minimum magnitude, Date range and Geographic Region and add that as a comment below.

Next, pick one of the following tools to visualize this data:

1. Tableau: Read about how to make proportional symbol maps (dots sized by data), and how to add a custom Mapbox style to Tableau.
2. Flourish: Try the Time Map template for a timeline view, or experiment with the 3D Marker map
3. Mapbox Studio + Mapbox GL: Check out the heatmap tutorial, timeline visualization tutorial and scrollytelling example. Also see Alli’s video tutorials on visualizing trees.
4. DataWrapper: Use the Symbol Map approach to bring in your data and create dots on a map.

For the final submission, make sure your visualization tells a story — choose an insightful heading, give it a description, use annotations & help the reader understand your story.

For inspiration, have a look at what your senior batch did: #38 & #44.

I downloaded earthquake data from USGS website. These were the filters I used:

Magnitude > 2.5 Date and Time: 1999-08-16T18:16:11.370Z to 2003-10-11T09:47:53.620Z Location: Region Around Bhuj, Gujarat

The devastating Bhuj earthquake of 2001 occurred on January 26, 2001, near the Pakistani border in Bhuj, Gujarat. The concept was to observe the sequential events occurring near Bhuj in the following years.

Earthquakes, Aftershocks, Foreshocks

Aftershocks are smaller earthquakes that occur in the days or even years following a larger event, or "mainshock"; and foreshocks are similarly smaller earthquakes that occur in the days leading up to the main incident.

I was especially interested in the 2004 Indian Ocean earthquake and tsunami, that occurred on 26th December 2004. Were there possibly smaller events leading up to and following this tragic incident? hypothetically, yes

Hence, I used the following filters- Magnitude: 2.5+ Date and Time: 2003-12-26 00:00:00 to 2005-12-26 00:00:00 (the incident occurred exactly in the middle of these two points) Location: Region Around Sumatra, Indonesia

Outcome:

timeline of earthquakes (2003-2005, Indian Ocean Region)

The graph does indeed show a series of smaller incidents in the year before the incident; followed by a sharp spike in December 2004, followed by another peak in 2005, before diffusing into a series of aftershocks.

The Pacific Ring of Fire: Unveiling a History of Devastating Earthquakes

The Pacific Ring of Fire, a geological wonder encircling the Pacific Ocean, continues to baffle experts with its relentless seismic activity. Renowned for its frequent and intense earthquakes, this horseshoe-shaped region has left an indelible mark on history, causing widespread destruction and loss of life. Seismic data from authoritative sources, such as the United States Geological Survey (USGS), underscores the region's staggering impact. A striking 81% of the world's most significant earthquakes originate here, a chilling testament to its geological potency. Over the past century, it has borne witness to 75% of history's deadliest quakes, spanning from minor tremors to catastrophic events.

Filters used: Magnitude: 7+ Date and Time: 1923-01-01 00:00:00 to 2023-08-26 00:00:00 (basically past 100 years) Location: Circum-Pacific Belt, a path along the Pacific Ocean

Magnitude > 5 Date and Time: 2000-01-01 to 2023-08-19 Location: Indonesia Source: USCG

I chose Indonesia as This Country has the highest earthquake happened and I filtered Magnitude as 5. Indonesia, a nation defined by its stunning landscapes and seismic activity, experienced a series of significant earthquakes between 2000 and 2023. These temblors, a reminder of Earth's dynamic nature, left indelible marks on the region. From the devastating 2004 Indian Ocean earthquake and tsunami that claimed countless lives, to subsequent quakes highlighting the nation's vulnerability, Indonesia's resilience shines amidst the tremors. These events spurred advancements in disaster preparedness, emphasizing the urgent need for global cooperation in safeguarding vulnerable communities against the earth's mighty rumblings.

{WORK IN PROGRESS}

Area Chose : China The country that experienced the most fatalities due to earthquakes is China. China is located on the top of the Eurasian plate, part of the Indian plate, and a small part of the Philippine Sea plate. Being located in such an active area, China has experienced many catastrophic earthquakes during its history and accounts for roughly half of all earthquake deaths.

Magnitude>7.5 Duration: 1885 - 2023 Location: Entire Map

Hypothesis: This unique map provides a glimpse into earthquakes that have occurred since 1885. Notably, this year marks the establishment of BHP, a significant mining company. Mining involves extracting valuable resources from the Earth's crust, which can sometimes have an impact on the stability of the ground. This connection raises intriguing questions about whether the activities of BHP and similar enterprises might have played a role in shaping seismic events. By observing the data on this map, we can explore the correlation between mining, seismic activity, and the dynamic forces at play beneath our feet

Magnitude≥6.5 Duration: 2000 - 2023 Location: Japan

Resilience Rising: Reflecting on Japan's 2011 Earthquake

The 2011 Earthquake in Japan was one of the deadliest earthquake in 21st century. On March 11, Japan is struck by an enormous 9.0-magnitude earthquake, unleashing a towering tsunami that levels communities along the country's north-eastern coast. Around 18,500 people are left dead or missing as the terrifying wall of water travelling at the speed of a jet plane swallows up everything in its path. The timeline map shows the scale of 2011 earthquake compared to others and how many 6.5 or above magnitude earthquakes (6.5 magnitude earthquake can easily destroy poorly constructed buildings) happened in Japan in 21st century.

Magnitude >5 Duration: 2000 - 2023 Location: Sichuan province, China

The Sichuan Earthquake

The [Sichuan earthquake of 2008] left over 5 million people homeless across the region, and over half of town of Beichuan was destroyed by the initial seismic event and the release of water from a nearby lake. Striking on May 12, 2008, the quake brought enormous devastation to the mountainous central region of Sichuan province in southwestern China. The epicentre of the magnitude-7.9 quake (measured as magnitude 8.0 by Chinese scientists) was in the city of Wenchuan, about 60 miles (100 km) north-northwest of Chengdu, the provincial capital; some four-fifths of the structures in that area were flattened. Whole villages and towns in the mountains were destroyed.

Earthquakes, as we know, occur due to disturbances (collisions) caused by the tectonic plates. Locating earthquakes over a period of time could help prove this point, or if we choose to go the other way around, plotting earthquakes over a long period of time could help us plot the edges of the tectonic plates. On plotting earthquakes of magnitude ≥ 6 that occurred from 1902-2022 (a span of 100 years), we see that the activity is not even across the edges of all tectonic plates and cannot be used to plot or even find many of these tectonic plates. The highest seismic activity can be seen on the Eastern edge of the Pacific Plate and hence the most affected nations include Japan, Korea, etc. There also seems to be higher activities along coasts which demarks that some tectonic plates are separated along these longer coasts such as that of South America and some of North America. There are still some interesting cases of earthquakes that are almost in the exact center of the major tectonic plates but there are very minute such cases.

Data : Min. magnitude - 2.5 to Max. magnitude - 10 Date range - Jan 1, 2015 till Jan 1, 2023 Geographic Region - East Africa

East African Rift: A Rift in the African Continent's Heart

The following map shows the East African Rift (EAR), a tectonic feature that stretches approximately 3,000 kilometers across eastern Africa. It illustrates the prominent geological processes at play, where the African Plate is gradually splitting into the Nubian and Somali Plates, causing the formation of deep rift valleys and volcanic activity. The East African Rift's ever-changing nature shapes the landscape, triggers earthquakes, and may lead to major geological changes in the future, drawing attention from geologists and scientists.
