Tongo Volcano
Country:Tonga Subregion Name:Tonga Islands Volcano Number:0403-04= Volcano Type: Submarine volcano Volcano Status:Historical Last Known Eruption: 1988 Summit Elevation: 149 m 489 feet Latitude: 20.57°S 20°34'0"S Longitude: 175.38°W 175°23'0"W
The small islands of Hunga Tonga and Hunga Ha'apai cap a large seamount located about 30 km SSE of Falcon Island. The two linear andesitic islands are about 2 km long and represent the western and northern remnants of a the rim of a largely submarine caldera lying east and south of the islands. Hunga Tonga and Hunga Ha'apai reach an elevation of only 149 m and 128 m above sea level, respectively, and display inward-facing sea cliffs with lava and tephra layers dipping gently away from the submarine caldera. A rocky shoal 3.2 km SE of Hunga Ha'apai and 3 km south of Hunga Tonga marks the most prominent historically active vent. Submarine eruptions were reported here in 1912 and 1937 and from a fissure 1 km SSE of Hunga Ha'apai in 1988.

<style type="text/css"> <!-- @page { size: 8.5in 11in; margin: 0.79in } P { margin-bottom: 0.08in } --> </style> (CNN) -- A tsunami warning was issued and then canceled Friday shortly after a major earthquake struck early Friday off the coast of Tonga.
The earthquake "generated a small tsunami," but there is "no evidence of destructive waves," said Stewart Weinstein, assistant director of the Pacific Tsunami Warning Center in Hawaii.
Robert Cessaro, a geophysicist with the center, said: "There's a tsunami in the water, but it's not gonna do much."
On the largest island in the Tonga chain, Tongatapu, in the capital city of Nukualofa, a clerk at the International Dateline Hotel said the earthquake was felt but caused no damage.
At the Fafa Island Resort, off Nukualofa, Joseph Sanladerer told CNN that the earthquake woke up guests and shook wine glasses from racks, but caused no significant damage.
The tsunami center issued the regional tsunami warning for parts of the Pacific near the quake's epicenter, about 213 kilometers (132 miles) south-southeast of Nuku'alofa, Tonga. The quake struck at 6:17 a.m. local time (6:17 p.m. GMT).
At a depth of just 6.2 miles (10 km), it is considered a shallow earthquake. Typically, the shallower the quake, the more destructive potential it carries. But that is not always the case.
The USGS recorded the quake as 7.9 magnitude; the Pacific Tsunami Warning Center said it was 7.7. There were no immediate reports of damage or death.
The earthquake struck a few hours after a volcano erupted off Tongatapu, Tonga, about 200 km away.
Ken Hudnut, a geophysicist at the U.S. Geological Survey in Pasadena, California, said: "The association with the volcanic activity seems to be an interesting added dimension to this. It's not clear at this point that there is a direct association, but it seems suggestive at this point."
The Indo-Australian geologic plate goes underneath the Pacific plate there, making earthquakes fairly common events in the area, called the Tonga Kermadec trench, he said.
