The earthquake and tsunami that just struck Indonesia's Sulawesi island is proving to be a tragedy that's still unfolding. "Earthquakes are caused by the Earth's tectonic plates sliding against or under each other. Case Study – Earthquake in Indonesia. This is happening constantly, but sometimes the movement is big enough and close enough to populated areas to have devastating consequences.A complex system of sensors were installed across the region.
The Caribbean has some areas with subduction and strike-slip faulting, and it is possible that we could be affected by a tsunami, but it would be a very rare event.“Large tsunamis are usually triggered by so-called megathrust faults associated with large, upward vertical movement,” said Guoqing Lin, associate professor of marine geosciences at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science, noting that the fault that ruptured on Friday along the coast of Sulawesi about 50 miles north of Palu was a strike-slip fault. The extensive flooding caused by the tsunami will have an immediate impact on vector mosquitoes, first by washing out immature stages of mosquito larvae from most habitats. Indonesia sits along the “Pacific Ring of Fire” where several tectonic plates collide and many volcanic eruptions and earthquakes occur.In this area, there’s subduction, so the Australian plate is moving under the Sunda plate, and the Australian plate is moving to the north underneath the Sunda plate.Supplies for those made homeless were distributed with about 30,000 tents and 100 wheelchairs sent to affected areas.Because these cookies are strictly necessary to deliver the website, you cannot refuse them without impacting how our site functions. 11 Dec 2018 Originally published 11 Dec 2018.

These are meant to help scientists quickly assess whether a quake is likely to trigger a tsunami, and alert the public to move to higher ground.When it comes to quakes, she says, "those are the areas to worry about".Indonesia experiences earthquakes every day, but the scale of the quake and tsunami which hit Palu on Friday took local people and scientists by surprise.As scientists explained to the BBC, a combination of geography, timing and inadequate warnings meant that what happened in Palu was a worst case scenario.It's not unusual for people to be killed by a tsunami because they stayed to look at the spectacle of the sea suddenly drawing back as the wave builds up.
The amount of refuse, debris, and flotsam after the tsunami is likely to a) increase exponentially the potential breeding habitats of the mosquito and b) lead to more bites from Aedes aegypti, which feeds actively during the day outside. "When water comes into a horseshoe-shaped area like that, instead of the wave increasing just because the ocean is getting shallow, you also have the bowl effect, where the waves are going to reflect off the shoreline around it. Other reports are speaking of tsunami's of 6 meter. Most of the boundaries are more or less straight on colliding with the ocean crust, subducting (going under the lighter continental crust). It was unprecedented in its scale, destroying parts of Sri Lanka, Indonesia and Thailand and resulting in over 250,000 deaths within the region.
The surge is much more than 3 feet higher than the real Andrew and penetrates much, much further inwards across Miami-Dade County. This movement along plate boundaries is mostly a sticky business with the rocks on either side sticking together and gradually building up stress.
