Unlike earthquakes felt elsewhere around the world, Hawai'i earthquakes are not usually the result of plate movement. Since Hawai'i sits in the middle of the Pacific plate, but is a volcanic hot spot, most earthquakes in Hawai'i have to do with the movement of magma in and below Hawai'i volcanoes. Every day the Big Island receives hundreds of small earthquakes, most too small to be noticeable. The Jaggar Observatory in the Hawai'i Volcanoes National Park constantly monitors earthquake sensors spread around the island and uses that information for eruption predictions. During normal volcanic activity the Big Island gets a handful of noticable earthquakes each month. These range from 2.0 to 4.0 in magnitude and rarely result in any damage. However we sometimes get more powerful earthquakes and during major eruptions we can experience quakes in the 5.0 to 8.0 range. Any earthquake that you cannot keep standing through may also result in a local tsunami being generated.

Our seismograph is dead center between the Begin Fault Zone and End of Fault Zone signs on Highway 11 in the Hawai'i Volcanoes National Park. The seismograph consists of three geophone sensors, one for each axis (East-West, North-South and Vertical). Each sensor delivers 200 samples per second (for a total of 600 samples per second) to a computer that sends it over the internet to our servers in Indiana where the data is plotted and made available to you on this page. Within two minutes of an earthquake happening in Hawai'i our charts should show the quake. For more information about the equipment and software click here. To view the latest 24 hours of seismic activity click here. To view confirmed USGS earthquake activity, as seen by our seismograph select the desired DATE from the events on the left. To understand how to read the charts click here. The chart below represents the most recent 24 hours of seismic data from our seismograph. The data at the very bottom of the chart is the most recent readings. To understand how to read the chart click here. How To Read The Charts The graphs on this site display three sensors of data. The chart begins at a UTC (Universal Time Code - same as GMT, Greenwich Mean Time) and shows a span of time up to 24 hours. The vertical (up/down) axis of the chart will show the UTC time in hours:minutes:seconds and the horizontal (left/right) will show seconds or minutes depending on the zoom of the chart. Because this program charts the data from any start point and any time span up to 24 hours, and because there is so much data involved, the program does not determine what the maximum magnitude for the signal during that time span prior to generating the chart. Because of this, some signals may not appear (during no activity) or some signals may appear too big (as in a major earthquake event). When a chart is rendered, near the top of the chart will a line that shows the samples per pixel, seconds displayed, sensors, total samples and amplitude chosen for the chart. The colors for the sensor data combine to produce a graph that allows you to determine how sensors interact. The chart to the right explains how this works.
