This animation discusses the tectonic setting, the history of M7+ earthquakes in Haiti, and the aftermath of the earthquake.
"Myth-Conceptions" is a series of 2 minute animations where we address common misunderstandings, misconceptions and myths in Earth science.
Whereas transform-fault and shallow-crustal-intraplate earthquakes have dominated the recent history of deadly and destructive earthquakes in Central America, we should never underestimate the potential destructive power of subduction zone earthquakes.
Earth’s thin, brittle outer shell of rock is under a constant state of stress. This animation explores how this stress impacts the formation of small local faults, and broader tectonic plate boundaries.
This 50s video introduces the 3 main types of faults and the motion that creates them. Perfect for the classroom!
Seismometers in Alaska have it rough - they experience extreme weather, months of darkness and frequent encounters with wildlife. Learn about how seismologists are "bear proofing" remote seismic equipment!
If you live in earthquake-prone regions it isn’t a question of IF, but WHEN an earthquake will occur. This animation shows quick steps to take if you are in a building, outside, in bed, in a classroom or lab, in a wheelchair, in a store, in a high rise, or in a car.
Large earthquakes are usually followed by hundreds and even thousands of smaller earthquakes, called aftershocks. In some earthquake sequences, a smaller earthquake called a “foreshock”, precedes the mainshock.
Placas Tectónicas: ¿Que son las Placas (litosféricas) tectónicas?

The theory of plate tectonics represents a fairly young science. This animation gives an overview of the most-recognized proponents (and opponents) of Plate Tectonics Theory from the 1600's into the 1960's.
The cool, rigid, outer layer of the earth, the lithosphere, is broken into massive plates along discrete boundaries. What are these plates, and what do the boundaries represent?
Lithospheric plates are part of a planetary scale thermal convection system. The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces.

Mega–terremotos de la Zona de subducción, los terremotos más potentes, pueden producir tsunamis a través de una variedad de estructuras que no son detectadas por los modelos simples. En esta animación exploramos diferentes mecanismos productores de tsunamis examinando tres terremotos famosos: Japón 2011, Chile 2010, y Alaska 2014.
Esto describe la dirección de desplazamiento en un terremoto y de orientación de la falla sobre la cual ocurre. Cuando se produce un terremoto, los sismólogos crean gráficos de mecanismos focales, informalmente conocidos como pelotas de playa para mostrar los movimientos de falla que producen un terremoto.
This animation integrates the unique and rich eruptive volcanic history of the Pacific Northwest in relation to the complicated tectonic regime revealed by seismology and geodetics in recent decades. We weave together geologic maps, time scales, and cross sections to help simplify and clarify elusive hidden structures and processes below Earth’s surface.
La intensidad sísmica, que es el temblor que experimentas, puede ser leve o severo, corto o largo, brusco o de bandeo. A diferencia de la magnitud de un terremoto, que es una medida de la energía liberada y es la misma para todos los lugares, la intensidad sísmica que percibes depende de dónde te encuentras.
Los científicos han desarrollado sismómetros mucho más sensibles, que con computadoras más rápidas, les han permitido registrar e interpretar un espectro más amplio de señales sísmicas, estas mejoras les permitieron determinar de una mejor manera la energía liberada por grandes terremotos.
Japan has more measurable earthquakes than any other country and has over 100 active volcanoes. The tectonics are complicated, but in this animation we look at the basic mechanics of the region as we focus on two famous earthquakes: the 1995 Kobe earthquake and the 2011 Tohoku-Oki earthquake.

Modern seismometers include 3 elements to determine the simultaneous movement in 3 directions: up-down, north-south,and east-west. Each direction gives information about the earthquake. This animation shows both the movement of the three basic waves (P, S, and surface) and the effect of the waves on a building.
