Discoverer: A Guide to Earthquake Data Sources

Earthquake information, research and studies. Click a region on the map to skip to that section >



Recent advances in technology have led to an explosion in the amount of geologic data available online. The number of seismic monitoring stations has increased from around three hundred in the 1930s to thousands today. Satellites, in continuous orbit around the planet, are able to measure small changes in topography related to earthquakes. Often, detailed preliminary information is available online within minutes of a quake occurring.

The sheer multitude of earthquake data sources can be confusing for decision makers and researchers who rely on the data to do their jobs. This webpage was developed to serve as a guide for those seeking earthquake data for seismic events anywhere in the world. Each continent has a different geologic setting and level of earthquake hazard.

We’ve provided a summary of continent-specific hazards including information about major historic earthquakes in each region. Below each summary is a list of links to useful data portals for each region.

Types of Earthquake Data

Sometimes the amount of seismic data available online can seem overwhelming. Luckily, there are a few categories into which nearly all of the data fits. We’ve summarized them below:

Parametric Data: These data describe a given ground motion event using several variables. Usually, parametric data will include the three dimension location of the earthquake within the Earth’s crust (hypocenter), the estimated earthquake magnitude, and data about the different types of waves produced by the earthquake. Some parametric datasets also include the epicenter, the location on the Earth’s surface directly above the hypocenter.
Waveform Data: Waveform data can be thought of as raw earthquake data, which can be analysed and interpreted to produce parametric data. While parametric data summarizes an earthquake based on information from many seismographs, waveform data is specific to an individual seismograph and does not in itself contain information about the location of an earthquake. Analysing waveform data allows us to study a certain event in more detail. By studying the arrival times of earthquake waves from a specific earthquake at multiple seismographs, geologists can determine the location of the hypocenter.

Hazard Maps: Hazard maps describe the probability of a seismic event with certain characteristic occurring at different locations on a map. They are useful for planners and geologists who specialize in geologic hazards.

Earthquake effects data: These data focus on the effects of an earthquake on human life and property. Usually, a summary of casualties and economic damages is associated with a given earthquake in the database. In general, these data sets are of greater interest to planners, insurance agencies, and earthquake response efforts than to seismologists.

From the famous 1906 earthquake (magnitude 7.8) that destroyed most of San Francisco to the 1989 Loma Prieta quake (magnitude 6.9), which closed down highways and collapsed bridges, Northern California has long been considered a prime example of an earthquake prone region. In reality, the earthquake risk in the USA is much more widespread than many people realize.

The greatest risk is concentrated along the West Coast. In California, the San Andreas fault is the primary structure producing earthquakes. Pressure has been building since the 1906 earthquake, and geologists are certain that another big quake will strike, probably within the next 100 years. To the north of the San Andreas lies the Cascadia Subduction Zone, where the Juan de Fuca plunges beneath the North American plate. No major earthquake has occurred here since European settlement, but one is expected within the next couple hundred years. It would likely be severe (magnitude >8) and is capable of producing a tsunami that could threaten countries as far away as Japan.

There is risk of small earthquakes in structures defining the western Rocky Mountains, but large earthquakes are relatively uncommon in the region.

To the east lies the New Madrid Seismic Zone, a zone underlying the states of Tennesee and Missouri. Although the reactivated rift zone has not had a major earthquake since 1812, geologists warn that it is capable of producing magnitude 8 earthquakes.

In the northeast US, a poorly understood system of ancient faults is capable of producing moderate earthquakes (magnitude <6) with low risk for catastrophic damage.

Canada and Alaska

Earthquake risk in Canada is centered on two regions.

The first is the St. Lawrence river valley in Eastern Canada. The valley is an ancient rift system that has been reactivated in modern times. The rift is closing at a rate of 0.5 mm per year and has produced several powerful earthquakes up to magnitude 7. There are many population centers in the region, including Quebec and Montreal.

The second zone of earthquake activity in Canada lies along the west coast. The Cascadia Subduction Zone (described in the USA section) continues into Canada, and is likely to produce a large (magnitude >8) earthquake within the next 200 years. The only major population center is Vancouver, but tsunami waves could affect countries in East Asia.

Alaska has been the location of some of the largest earthquakes ever recorded, including the Great Alaska Earthquake of 1964 (magnitude 9.2), which heavily damaged Anchorage and outlying communities. Most major earthquakes in the region are caused by the Aleutian Megathrust fault, a major subduction zone that extends across southern Alaska.

South America

The west coast of South America has been struck by some of the most devastating earthquakes in history, including the 1960 Valdivia Earthquake in Chile, the largest ever recorded (magnitude 9.5). The most famous account of an earthquake in the region was made by Charles Darwin, who experienced the 1835 Conception earthquake (magnitude 8) and wrote about it in “The Voyage of the Beagle”.

Most earthquakes in South America are related to the subduction of plates underlying the Pacific Ocean beneath the continent. A nearly continuous subduction zone runs along the entire west coast of South America, creating a high earthquake risk in Chile, Peru, Ecuador, and Colombia. Steep mountain roads and quake prone buildings make the Pacific Coast of South America one of the world’s most dangerous places to be during and after a major earthquake.

Central America and southern Mexico are also prone to subduction related earthquakes. Far northwestern Mexico is subject to the effects of movement along the San Andreas Fault, although the risk of a major earthquake is low.

Earthquake risk in Europe is concentrated in Italy, Greece, and the Balkans. The largest earthquake recorded in Europe is the 1908 Messina earthquake (magnitude 7.1), which struck Sicily and the southern tip of the Italian peninsula, killing 100,000 to 200,000 people.

Most tectonic activity in Europe is related to the ongoing collision with Africa, which is responsible for the Alps, the Pyrenees, and most other topographic features in southern Europe. The geology of Europe is quite complicated, meaning that earthquake risk can vary greatly over relatively small distances. However, earthquake risk in Northern Europe is minimal due to the greater distance from a plate boundary.

Africa is, for the most part, relatively geologically stable. However, there are two major areas prone to earthquakes. One is the East Africa Rift Zone, which is forming as Africa is pulled apart along a north-south axis. The other is a seismic zone in northern Africa related to the ongoing collision with Europe. Both of these regions experience earthquakes up to magnitude 7.5.

Although very large earthquakes are rare in Africa, they can have major economic and social consequences when they do occur.

The geology of Asia is extremely complex, and the size of the region makes it difficult to generalize about earthquake risk. There are three major tectonically active zones:

The first, in the Middle East, is the Zagros fold and thrust belt, which underlies much of Iran. Large earthquakes (magnitude 8) have occurred throughout history in the region, which is being deformed as the Arabian Peninsula collides with the Asia.

The second major active region is the Himalayan Orogeny, which consists of the Himalaya and Hindu Kush mountains, as well as the Tibetan Plateau and south-central China. Earthquakes here are related to the collision between the Indian subcontinent and Asia.

The third region consists a major subduction zone that extends from the Kamchatka Peninsula south to Japan. This region has produced some of the world’s largest earthquakes and many damaging tsunamis. The 2011 Tohoku earthquake (magnitude 9.0) lasted six minutes and caused widespread destruction. A large tsunami followed the earthquake and destroyed many coastal towns, and, famously, disabled the Fukushima Nuclear Power Plant.

Microseimic monitoring in Nepal started in November, 1978 by Department of Mines and Geology (DMG), Ministry of Industry, government of federal democratic republic of Nepal in collaboration with Laboratoire de Geophysique Appliquee, Paris University, France with the installation of first short period vertical seismic station Phulchoki(PKI) hilltop in the south of Kathmandu.


Earthquakes in Oceana are centered along the plate boundaries making up the Pacific Ring of Fire, where the Pacific Plate and other related plates are subducting beneath continents and island arcs. Particularly at risk are New Zealand, Singapore, the Philippines, Indonesia and Papua New Guinea. These regions are capable of experiencing megathrust earthquakes up to magnitude 9.

In 2004 a major megathrust earthquake occurred off the coast of Sumatra, where the Indian plate subducts beneath the Indonesian Island Arc. The earthquake (magnitude 9.3) was the third largest ever recorded. It generated a large tsunami that killed over 230,000 people, making the quake one of the largest disasters in recorded history.

In New Zealand, the Alpine Fault is a strike-slip fault capable of creating large earthquakes up to magnitude 8. In 2011, a magnitude 6.3 earthquake struck the Canterbury region of New Zealand, significantly damaging the city of Christchurch.

Islands located away from the edges of the Pacific Plate are almost entirely free of earthquakes (except those caused by volcanic activity).

Volcanic Seismic Data

Volcanoes are capable of producing localized large earthquakes as well as powerful atmospheric shock waves. Often, detailed seismic data associated with a specific volcano allows geologists to predict massive eruptions with a modest degree of accuracy. Many of the websites focusing on volcanoes are updated very frequently, especially for active volcanoes in regions where they might affect human safety.

Unlike non-volcanic seismic data, which is collected by a global network of seismographs, volcanic seismic data is collected on or near the volcano itself. Although some volcanoes have permanent seismograph networks, most networks are set up when the activity at a volcano increases. Because volcanic earthquakes are often localized, the databases are often incomplete – only a small percentage of the world’s active volcanoes are being monitored at any one time, so a lot of seismic events are missed.
