Jenlogix Records Impact of Recent Fiji and Kermadec Quakes
Following the 7th September earthquake Jenlogix collected wave forms from seismometers in the Wellington region. The company has 60 plus seismometers in the region. The seismic waves of the 608km deep earthquake took several minutes to arrive in the capital.
In this instance the tremors were not big enough to create one of their automated shake maps, which are usually sent to their clients within 60 seconds of their sensors picking up a quake. Jenlogix’s website features wave forms from BECA’s Molesworth St office and the Red Wolf High Level Security offices in Lower Hutt.
A powerful magnitude 7.8 earthquake rocked the island nation of Fiji during the early hours of Friday 7th September. The quake struck at 3.49am about 100km from the capital, Suva. The Pacific Tsunami Warning Centre (PTWC) originally recorded the quake at 8.1 before downgrading it to 7.8. PTWC said there was no tsunami threat because the earthquake was located too deep inside the earth. Civil Defence confirmed there was no tsunami threat to New Zealand.
More recently thousands of people have reported feeling a 6.9 magnitude earthquake which hit near the Kermadec Islands on September 10th. The tremor, centred south of the Kermadec Islands, was initially reported as 6.8 magnitude but was revised to 6.9, GNS Science said. GeoNet said the quake could be felt across the country, from the East Coast to the South Island.
Seismologist John Ristau said even though the GNS automated system reported several small earthquakes in New Zealand, it was not the case. "People aren't imagining that they felt anything, they did feel it. They're just feeling this large earthquake that's a few hundred kilometres away, north of the North Island." The Jenlogix shake map was produced as it recorded ground movement.
Earthquake early warning systems from Jenlogix are important for facilities around the country. Jenlogix stocks detectors like Palert an advanced earthquake P wave alarm detector system from Taiwan. Palert uses embedded Pd technology to reduce earthquake damage by providing as much warning as possible at an affordable cost. The Palert only requires 3 seconds once a P-wave is detected to issue an alarm if it calculates that the following shockwave is likely to be of a significant level to cause damage.
