Giant countries like Canada or Russia can take their sprawling landmasses for granted, but for smaller oceanic nations, topography takes on greater importance.
In the Indian Ocean, ringed by protective barriers, lies the island city of Malé – the capital of the Maldives. Malé has a thriving tourism industry and is one of the most urbanized islands in the world, but it has one major problem: its elevation (or lack thereof).
Over 80% of the nation’s landmass is below 3.3 ft (1m), leaving it acutely vulnerable to the impacts of climate change. If sea levels continue to rise, the entire chain of islands, including the homes of half a million people, could be submerged in as soon as 30 years.
Breaking out the measuring stick
Today’s data visualization, via Fascinating Maps, is a global breakdown of every country’s elevation span, from the severe mountain peaks that dominate Bhutan’s landscape, to the sweltering Dead Sea depression that runs along the Israel–Jordan border.
By looking at the data, we see interesting patterns and unique situations emerge.
The Power of Zero: The median low-end land elevation of the world’s countries is zero. This is because shoreline typically makes up the lowest portion of a country’s terra firma. It’s easy to spot a landlocked country in the data set, as its lowest elevation is far more likely to be above sea level.
The Lowlands: In general, the smallest countries tend to have the smallest elevation spans, but some countries buck that trend. Denmark, which has a respectable 16,577 quare miles (42,933 sq. km) of land, has an elevation range of only 583 ft (178m). This means the highest point in the country is only 50m taller than its tallest building, Herlev Hospital, near Copenhagen.
The Highlands: Three countries – Nepal, Tajikistan, and Bhutan – have an average elevation that soars above 10,000 ft (3,050m). The latter country has the highest average elevation in the world.
Bhutan Elevation Map:
Supersized Elevation Span: China has the the largest elevation span of any country on Earth. The average elevation of the country skews high, thanks in part to the Tibetan Plateau. A number of the highest permanent settlements in the world exist in this region.
How People and Companies Feel About Working Remotely
During the pandemic, millions of people have transitioned to working remotely. But how do workers and managers actually feel about it?
According to the U.S. Census Bureau, nearly one-third of the U.S. workforce, and half of all “information workers”, are able to work from home. Though the number of people working partially or fully remote has been on the rise for years now, the COVID-19 pandemic may have pressed the fast-forward button on this trend.
With millions of people taking part in this work-from-home experiment, it’s worth asking the question – how do people and companies actually feel about working from home?
The Flex Life
It’s no secret that people value freedom of choice. A whopping 98% of people would like to have the option to work remotely for the rest of their careers.
Aside from working in sweatpants, what are the things people like about working from home?
A flexible schedule, the ability to work from any location, and no more commuting were the top reported benefits.
Of course, not everything is positive about working from home. Here are some of the challenges people face as they work remotely.
The top issue faced by remote workers was “unplugging” from work. Without the clear-cut change of location and defined office hours, many people had a tougher time clearly dividing their personal and professional time.
As well, the lack of person-to-person communication can be a challenge for some people. In fact, one-third of people were concerned that the full extent of their professional efforts wouldn’t be appreciated because of a lack of in-office contact.
For the majority of people, having tough conversations via phone or teleconferencing software was actually viewed as a positive development.
Barriers to Implementing a Remote Work Policy
Despite the popularity of remote and flexible working, not every company has embraced the concept. Here are some of the reasons why.
While there can be technical or security-related reasons behind remote work resistance, a major barrier is simple resistance to change. Over 50% of companies that didn’t have a flexible or remote workplace policy cited “longstanding company policy” as the reason. In other words, that is just the way things have always worked.
Here are the reservations managers have with remote work:
Managers are worried that productivity and focus will be diminished if people are working in more informal locations, such as home or a cafe. Also, if people aren’t working in the same physical location, managers feel that team cohesiveness and company culture could suffer.
On the flip side, the cost savings associated with remote work may win over many companies. Research has found that typical employer can save about $11,000 per year for every person who works remotely half of the time. As well, switching to virtual meets in some instances can also be a significant cost savings.
Flexibility: The Ultimate Perk?
Location flexibility isn’t just a way to keep current employees happy. Companies that don’t embrace flexible working may find themselves at a disadvantage when recruiting new talent. Nearly two-thirds of candidates say that having a choice of work location is a key consideration in choosing an employer.
Lockdown measures have highlighted the value of workplace flexibility – particularly for people with kids. A total of 86% of parents now want to work flexibly, compared to 46% pre-coronavirus.
As the economy slowly begins to reopen, it remains to be seen whether or not COVID-19 accelerated inevitable trends in workplace culture. If so, taking Zoom calls in sweatpants may become the new normal for millions of workers.
Visualizing the Power and Frequency of Earthquakes
Our planet is in a constant state of creation and destruction as the plates of the earth collide. This visualization looks at earthquake magnitude.
Visualizing the Power and Frequency of Earthquakes
The surface of our planet is in a constant state of creation and destruction as the plates of the Earth collide. It is this movement of the Earth’s crust that causes earthquakes, sending tremors throughout the world.
Today’s graphic is inspired by a classic USGS diagram that tracks the scale and frequency of earthquakes.
Earthquakes occur because the crust of the Earth is made up of several plates. The boundaries of these plates create faults that can run into one another.
Earthquakes describe both the mechanism that causes a sudden stress release along plate boundaries and also the ensuing ground shaking.
They occur when stress builds up along a tectonic fault. This stress causes the two surfaces of the fault, which had previously been stuck together due to friction, to suddenly move, or slide, releasing energy in the form of seismic waves.
Measuring an Earthquake’s Impact
There are three factors to assess the impact of Earthquakes – magnitude, energy, and intensity.
Magnitude is a number most commonly associated with the Richter scale, describing the size of an Earthquake on a scale from 0 to 10 – the latter of which is the maximum motion recorded by a seismograph. Each increase by one on the scale represents a tenfold increase in the amplitude. There are over a million tremors around the planet each year, but it’s not until an earthquake reaches a magnitude of 4 that humans can typically feel it.
Another way to measure the size of an earthquake is by how much energy it releases. The amount of energy radiated by an earthquake is a measure of the potential for damage to man-made structures.
An earthquake releases energy at various frequencies, and in order to calculate accurately, you have to include all frequencies of shaking for the entire event. Some research suggests technology could harness this energy for power generation.
Intensity describes the severity of an earthquake with a qualitative evaluation of its effects on the Earth’s surface and on the built environment. An earthquake may have a high magnitude but if a city or landscape experiences little damage, it can be said that the intensity is low. The Modified Mercalli Intensity Scale measures this intensity.
The World’s Largest Earthquakes by Magnitude
Prior to the development and use of seismographs, around 1900, scientists could only estimate magnitudes, based on historical reports of the extent and severity of damage.
|May 22, 1960||Valdivia, Chile||9.4-9.6|
|March 27, 1964||Prince William Sound, Alaska||9.2|
|Dec. 26, 2004||Indian Ocean, Sumatra, Indonesia||9.1|
|March 11, 2011||Pacific Ocean, Tohoku Region, Japan||9.1|
|July 8, 1730||Valparaiso, Chile||9.1-9.3 (est.)|
|Nov. 4, 1952||Kamchatka, Russia||9|
|Aug. 13, 1868||Arica, Chile||8.5-9.0 (est.)|
|January 26, 1700||Pacific Coast, Modern Day British Columbia||8.7-9.2 (est.)|
|April 2, 1762||Chittagong, Bangladesh||8.8 (est.)|
|Nov. 25, 1833||Sumatra Indonesia||8.8 (est.)|
Earthquakes are a fact of life on Earth and mark distinct moments in history. One would think given our knowledge of earthquakes, that humans would avoid these locations – however, the very faults of the Earth also create its greatest advantages.
Living with Your Faults
It’s extremely common to find human settlements along the fault lines where earthquakes occur most frequently. Some could say that this is because these decisions were made before a complete understanding of science enabled us to know the potential risks involved.
However, a recent scientific study reveals that there may be more to the pattern than previously thought. Tectonically active plates may have produced greater biodiversity, more food, and water for our human predecessors.
Certain landscape features formed by tectonic processes such as cliffs, river gorges, and sedimentary valleys create environments that support access to drinking water, shelter, and an abundant food supply.
This inherent problem reveals that humans are more connected to their environments than previously thought. It comes down to a question of how well humans can adapt their lifestyle and built environments to a dynamic planet.
Now let’s worry about the asteroids…
