However, the earthquakes which occur most frequently are often too small to cause significant damage whether to human life, or in economic terms. Significant earthquakes are those which are large enough to cause notable damage. Available data — which you can explore in the chart below — extends back to BC.
But we should be aware that most recent records will be much more complete than our long-run historic estimates. In the chart below we see the estimated mortality numbers from BC through to At the global level we see that earthquake deaths have been a persistent human risk through time. The number of people dying in natural disasters is lower today than it was in the past, the world has become more resilient. Earthquakes, however, can still claim a large number of lives. Whilst historically floods, droughts and epidemics dominated disaster deaths , a high annual death toll now often results from a major earthquake and possibly a tsunami caused by them.
Since , the two peak years in annual death tolls reaching s of thousands were and Earthquake deaths accounted for 93 percent and 69 percent of such deaths, respectively. In fact, both events the Sumatra earthquake and tsunami of , and Port-au-Prince earthquake in are in the deadliest earthquake rankings below. What have been the most deadly earthquakes in human history?
In the visualization below we have mapped the top 10 rankings of known earthquakes which resulted in the largest number of deaths. The most deadly earthquake in history was in Shaanxi, China in This is more than twice that of the second most fatal: the recent Port-au-Prince earthquake in Haiti in Two very recent earthquakes — the Sumatra earthquake and tsunami of , and Port-au-Prince earthquake — feature amongst the most deadly in human history.
But equally, some of the most fatal occurred in the very distant past. Making the top three was the earthquake in Antakya Turkey in the year Both old and very recent feature near the top the list. The deadly nature earthquakes has been a persistent threat throughout our history. There are a large number of volcanoes across the world which are volcanically active, but display little or only very low-level activity. In the map we see the number of significant volcanic eruptions which occur in each country in a given year.
Estimates of volcanic eruptions are available dating back as early as BCE, however, the data completeness for long historic events will be much lower than in the recent past. In the visualization we see the number of deaths from significant volcanic eruptions across the world. Using the timeline on the map we can see the frequency of volcanic activity deaths over time.
As we would expect, the risks of landslides are much greater close to highly mountainous regions with dense neighbouring populations. This makes the mortality risk highest across the Andes region in South America, and the Himalayas across Asia. We cover the history of Famines in detail in our dedicated entry here. For this research we assembled a new global dataset on famines from the s until In the visualization shown here we see trends in drought severity in the United States.
Given is the annual data of drought severity, plus the 9-year average. This is measured by the The Palmer Drought Severity Index: the average moisture conditions observed between and at a given location is given an index value of zero. A positive value means conditions are wetter than average, while a negative value is drier than average.
A value between -2 and -3 indicates moderate drought, -3 to -4 is severe drought, and -4 or below indicates extreme drought. Trends in the US provide some of the most complete data on impacts and deaths from weather events over time.
This chart shows death rates from lightning and other weather events in the United States over time. Death rates are given as the number of deaths per million individuals.
Over this period, we see that on average each has seen a significant decline in death rates. This is primarily the result of improved infrastructure, predicted and response systems to disaster events.
A key metric for assessing hurricane severity is their intensity, and the power they carry. The visualizations here use two metrics to define this: the accumulated cyclone energy ACE , an index that measures the activity of a cyclone season; and the power dissipation index of cyclones. In the visualization shown we see the global precipitation anomaly each year; trends in the US-specific anomaly can be found here.
This precipitation anomaly is measured relative to the century average from to Positive values indicate a wetter year than normal; negative values indicate a drier year. Also shown is US-specific data on the share of land area which experiences unusually high precipitation in any given year. We can look at precipitation anomalies over the course of year, however, flooding events are often caused by intense rainfall over much shorter periods.
Flooding events tend to occur when there is extremely high rainfall over the course of hours or days. The visualization here shows the extent of extreme one-day precipitation in the US. What we see is a general upwards trend in the extent of extreme rainfall in recent decades.
Extreme temperature risks to human health and mortality can result from both exposure to extreme heat and cold. In the visualizations shown here we see long-term data on heatwaves and unusually high temperatures in the United States.
Overall we see there is significant year-to-year variability in the extent of heatwave events. What stands out over the past century of data was the North American heatwave — one of the most extreme heat wave events in modern history, which coincided with the Great Depression and Dust Bowl of the s. Whilst we often focus on heatwave and warm temperatures in relation to weather extremes, extremely low temperatures can often have a high toll on human health and mortality.
In the visualization here we show trends in the share of US land area experiencing unusually low winter temperatures. In recent years there appears to have been a declining trend in the extent of the US experiencing particularly cold winters.
In the charts below we provide three overviews: the number of wildfires, the total acres burned, and the average acres burned per wildfire.
This data is shown from onwards, when comparable data recording began. Over the past years we notice three general trends in the charts below although there is significant year-to-year variability :. The original statistics are available back to the year When we look at this long-term series our chart is here it suggests there has been a significant decline in acres burned over the past century. However, the NIFC explicitly state:.
Prior to , sources of these figures are not known, or cannot be confirmed, and were not derived from the current situation reporting process. As a result the figures prior to should not be compared to later data. The lack of reliable methods of measurement and reporting mean some historic statistics may in fact be double or triple-counted in national statistics.
This means we cannot compare the recent data below with old, historic records. Historically, fires were an often-used method of clearing land for agriculture, for example. This chart shows the declining death rate due to lightning strikes in the US. In the first decade of the 20th century the average annual rate of deaths was 4.
In the first 15 years of the 21st century the death rate had declined to an average of 0. This is a fold reduction in the likelihood of being killed by lightning in the US.
The objective of this series is to help first time home buyers understand the steps and gain a good level of knowledge and confidence within the home buying process. An informed buyer is a confident buyer. The key to maintaining financial health is not only in the planning and managing of one's personal assets but in understanding the basics and evolution of the economy. The economy affects every part of our lives, yet many school districts do not offer economics and graduating without it is possible.
In our households, money is rarely discussed, except for the idea of running out of it. Let's all start taking a proactive approach to becoming well-rounded in economics and finance, in order to make better everyday decisions for ourselves, and generations to come.

While a single heat wave might not be as catastrophic as a major hurricane, heat waves are more common, which means they ultimately can result in more deaths and injuries over several years. Although the greatest number of deaths from a single disaster might occur in places with large populations, these are not necessarily the areas where individual residents are most likely to die from such an event in the United States. The areas with the greatest mortality risks are in the South Atlantic and Gulf coasts, the lower Mississippi River valley, the northern Great Plains, south-central and southwestern Texas, and the Rocky Mountain West.
People living in urbanized areas, particularly in the Northeast, have the lowest mortality risk, mainly because the number of deaths from natural hazards is small relative to the large population size. According to the authors, identifying the areas most prone to disaster-related deaths could result in more resources for these areas aimed at prevention. Tangshan, an industrial city with a population of about 1 million at the time of the disaster, suffered staggering casualties of over , While this was the official death toll, some experts suggest this number is grossly underestimated and that the loss of life was likely closer to , It took several years before the city of Tangshan was rebuilt to its prior glory.
As with all disasters occurring millenia ago, a precise death toll for the Antioch earthquake is hard to come by. Contemporary chronicler John Malalas wrote at the time that about , people died when the temblor hit the Byzantine Empire city now Turkey and Syria in May, Malalas attributed the disaster to the wrath of God and reported that fires destroyed everything in Antioch that the earthquake did not.
According to a paper in The Medieval History Journal , the death toll was higher than it would have been at other times of the year because the city was full of tourists celebrating Ascension Day — the Christian feast that commemorates Jesus' ascension into heaven.

The USGS reported total casualties of ,, but according to a study by Chinese seismologists, the death toll could have been as high as , The region's high deposits of loess soils porous, silty sediment that's very unstable triggered massive landslides which were responsible for over 30, of these deaths, according to a study published in the journal Landslides.
The hurricane's wind speeds and category are not known, as is the case for many storms that took place before the 20th century. About 20, ships and vessels were destroyed, along with the lives of an estimated , people.
Tying the Coringa cyclone as the sixth deadliest natural disaster is the typhoon that hit the port city of Haiphong in northeastern Vietnam on October 8.
